benign squamous epithelium

WebPresence of human papillomavirus DNA in benign and precancerous oral leukoplakias and squamous cell carcinomas A variety of benign squamous epithelial lesions of the mucosa are associated with human papillomaviruses (HPV). 24 In children, they are typically pedunculated, multiple, and located inferiorly in the fornix. Adenosquamous carcinomas show malignant features such as frequent mitoses, cellular or nuclear atypia or invasion into surrounding tissues, lymphatics, vessels or metastases. The tumor consists of proliferating squamous epithelia arranged in prominent folds with fibrovascular stroma (Figure 19.17). Endoscopy. 2019;52:725. Kato H, Orito E, Yoshinouchi T, et al. Multiple squamous papillomas of the esophagus associated with Goltz syndrome. Amano T, Nishida T, Inada M. Diffuse esophageal papillomatosis in a patient with acanthosis nigricans. A total of 21 cases showed that the papillomatosis spread throughout the whole esophagus. Nevertheless, is it necessary to provide positive treatments to each patient suffering from EPS? Provided by the Springer Nature SharedIt content-sharing initiative. J Laryngol Otol. 1990; Ito and Hirose 1989). Squamous cell papillomas are benign tumors of the conjunctiva in which acanthotic squamous epithelium covers fibrovascular cores (Fig. The lesions usually appear as small, white or pink colored, with a smooth or slightly rough surface, sessile or pedunculated forms and with a close-set pattern (Fig. Washington DC: Armed Forces Institute of Pathology; 1957. p. 2532. 2001;58:2338. Department of Gastrointestinal Medicine (Endoscopy Center), Jilin University, China-Japan Union Hospital, 126 Xiantai Street, Erdao, Changchun, 130033, Peoples Republic of China, Dandan Li,Changfeng Li,Yuxing Yan&Minya Liu, You can also search for this author in A large number of non-DNA-reactive chemicals cause tumors in the forestomach by increasing proliferation. Inverted squamous cell papillomas with mild cytologic atypia may be indistinguishable from invasive squamous cell carcinoma. Unfortunately, the treatment effects were poor and resulted in a repeated recurrence [7]. The cytoplasm is eosinophilic and granular to hyalinized as a result of the high keratin content. Squamous cell papillomas should be discerned from inflammatory polyps and squamous cell carcinoma. The inner lining of the esophagus is known as the mucosa. Carcinoma features epithelial crowding and malignant cytology and usually demonstrates bronchial wall invasion. 2012;27:243. Numerous chemicals produce squamous cell papillomas and carcinomas of the forestomach in rodents, especially in rats (Clayson et al. EPS is an extremely rare disease that has no standard therapeutic or surveillance guidelines. An irregular thickened layer of keratin (parakeratosis) is present on the surface of the papilloma. Conjunctival papillomas are categorized into infectious (viral), squamous cell, limbal, and inverted (histological description) based on appearance, location, patient's age, propensity to recur after excision, and histopathology. Syrjnen KJ. Recently virus-specific DNA was also detected in oral invasive CAS The mass is composed of islands, cords or nests of cells that penetrate the basal lamina and invade deeply into the dermis; tumor cells may reach the subcutis and subcutaneous muscle. For instance, a 3.5-month-old boy suffering from EPS and RRP, with HPV type 6 and 11 infections, underwent a total of 11 repeated microlaryngoscopic surgeries and laser photocoagulation. Figure 16. A rare case of esophageal papilloma due to human papillomavirus with uncommon presentation of dysphagia in a 2-year-old child. Suprabasal cells show gradual squamous keratinization with a thickened granular cell layer and irregularly enlarged keratohyalin granules. Recently virus-specific DNA was also detected in oral invasive carcinomas. Terms and Conditions, The prevalence of HPV in these different lesions varies, which makes a causative link difficult to establish. The specimen revealed a cystic structure lined by mature keratinizing squamous epithelium with a prominent granular cell layer consistent with a squamous inclusion cyst in a lymph node, but a metastatic squamous cell carcinoma could not be excluded. In the EPS reports, delivery [6], sexual [29], and direct contact transmission [24] may facilitate HPV implantation. Other tumors include lymphomas, endocrine and mesenchymal lesions, rare primary melanoma, and metastatic tumors. Papillomavirus in esophageal papillomas and carcinomas. WebThere are two main types of benign epithelial tumors, depending on the type of the proliferating epithelium : papilloma and adenoma. Focal dermal hypoplasia (Goltz syndrome) manifesting with esophageal papillomatosis. Figure 2.7.20. It is imperative that you follow your doctor's instructions about follow-up tests. Squamous cell papillomas, also known as skin tags or fibroepithelial polyps, are extremely common (Figure 16). ACG Case Rep J. The tumours have malignant glandular and squamous epithelial components. Of course, the most common course is a slow progression. 1959;37:62535. J Pathol. AskMayoExpert. YY and ML were in charge of looking up the literature. Alomari M, Wadhwa V, Bejarano P, et al. volume18, Articlenumber:99 (2023) HPV infection in ~90% of cases(most commonly type 16). EP prevalence varies from 0.007 to 0.45% [4, 5] and solitary EP is often observed under endoscopy. Esophageal papillomatosis in the adult. 1982;52:28392. Ravakhah K, Midamba F, West BC. Singhal S, Baker RD, Khan A, et al. Zhonghua Yi Xue Za Zhi Chin Med J (Taipei). Interestingly, some patients acquired EPS, 13year after esophageal carcinoma esophagectomy and gastric carcinoma surgery [17, 49, 58, 61], in which gastroesophageal reflux may play an important role during the process. Romano A, Grassia M, Esposito G, et al. the unsubscribe link in the e-mail. Plexiform intercellular fibrils are a diagnostic feature. This is what the Dr saw in your Pap smear. Saravanan R, Youshya S, Campbell F, et al. Well-differentiated squamous cell carcinoma can be papillary and endobronchial but usually demonstrates malignant cytologic features in addition to irregular infiltrating nests of cells within desmoplastic stroma. J Gastroenterol Hepatol. Other chemical factors, such as tobacco and alcohol abuse are also considered as a lifetime risk of EP [10, 14], which can also be found in EPS cases. Boorman's Pathology of the Rat (Second Edition), Mandell, Douglas, and Bennett's Principles and Practice of Infectious Diseases (Eighth Edition). Intercellular bridges are readily observed in areas with squamous differentiation. Tanaka S, Goubaru M, Ohta T, et al. If these findings are seen in an excision biopsy, no further action is needed. 3, 4 The overlying squamous epithelium generally has an orderly maturation, resembling normal esophagus ( Figure 1, A), though mild atypia can be seen in the spiked papilloma. Various endoscopic treatments were used to manage the EPS lesions, including argon plasma coagulation (APC), Nd-YAG laser, radiofrequency ablation, cryotherapy and photodynamic therapy (PDT). 2012;44:E1101. WebSquamous cells are found in the anal canal. However, if they are found on a needle biopsy, it isnt so simple. Nasal adenosquamous carcinomas are believed to develop by malignant transformation of respiratory epithelium, submucosal gland duct epithelium or basal and sustentacular cells of the olfactory epithelium, or from areas of metaplasia in the epithelia.

The exophytic type is considered to be a pedunculated papilloma. Batra PS, Hebert RL, Haines GK, et al. Am J Gastroenterol. Arch Geschwulstforsch. Siu W, Murray GI, McKinlay A, et al. They usually arise in the most anterior part of the nasal cavity, originating from the mucosa of the naso- or maxilloturbinates or from the lateral wall of the anterior nasal cavity. Other EPS cases can also be found to be associated with oropharyngeal cancer and gastric adenocarcinoma [27, 62, 63], for which there are no suitable explanations. Papillomas are generally larger than hyperplastic lesions but still show orderly cell maturation. Perhaps, this is due to the broad use of endoscopy and related research achievements. This can happen spontaneously. 2019;6:14. In this report, multiple EP was first described as EPS. You'll soon start receiving the latest Mayo Clinic health information you requested in your inbox. An example of differential X-chromosome inactivation. More than one in six patients lost weight and some asymptomatic patients were accidentally discovered [8, 45,46,47,48]. 419080500365)]. Lio WJ, Huang CK, Chen GH. Dysphagia is the first observed symptom and constitutes the most typical manifestation of this condition. Combined extensive esophageal squamous papillomas and florid cardiac gland hyperplasia in a patient with adenocarcinoma. 1996;22:357. However, the choice of surgery is still prudent due to the cases that are mostly benign. and ectocervical tissue with koilocytic Nat Genet. EPS treatment is controversial and extremely challenging due to the extensive nature of the lesions and the repeated recurrence. The appearance of koilocytes, expressing hyperchromatic nuclei and perinuclear halos, supports an HPV squamous epithelium infection. And half of the cases suffered from esophageal cancer [15, 26]. Squamous Papilloma Esophageal squamous papillomas are benign epithelial tumors most often found in the distal esophagus [ 2 ]. Unique expression of human papilloma virus type 5 and type 16 in esophageal squamous cell carcinoma? Squamous cell papilloma of the nonglandular stomach (3-chloro-2-methylpropene). Ferrari AP, Martins FP. Or it can be the result of a specific treatment. 1998;316:2858. Oesophageal papillomatosis, not amenable to endoscopic therapies, treated with oesophagectomy. HPVs 6 and 11 have also been linked to recurrent respiratory papillomatosis. I had a biopsy done on my cervix, and i am trying to understand my results specimen a-minute fragments of benign endocervical glands, squamous epithelium, blood, and mucus? Because of the papillary nature of the lesion, clusters of epithelial cells may appear in the stalk as the result of tangential sectioning. A portion of the neoplasm is exophytic, with ulcer or erosin on the surface; however most cases are poorly demarcated endophytic masses (Figure 19.18). Dis Esophagus. 2001;16:85761. Fifty cases including benign cervical tissue, low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), adenocarcinoma in situ of the endocervix, invasive endocervical adenocarcinoma, and endometrial adenocarcinoma were selected. Neuroepithelial carcinoma showing rosettes and pseudorosettes. Location of the tumour usually determines the cell type of the adenoma (transitional or respiratory epithelial type, submucosal glandular). They may be translucent or opaque, whitish to yellow, and range from a few millimeters to 3 to 4 cm in diameter. Frequency and morphology of rosette structures are highly variable.

Abnormal squamous cells are classified as squamous intraepithelial lesion (SIL) and are either low grade or high grade: Low-grade SIL (LSIL) compares to CIN 1 Gencdal G, Degirmencioglu S, Akyldz M. Diffuse esophageal squamous papillomatosis covering the entire esophagus. Among the EPS cases, more than a quarter of patients had a prolonged chronic reflux disease and repeated heartburn. Progressive hyperplasia of the papillae and epithelium led to the formation of papillomas. Endoscopy. Alcohol, smoking and papillomavirus infection as risk factors for esophageal squamous-cell papilloma and esophageal squamous-cell carcinoma in Italy. Local injections of HPMPC were performed 10 times during the 7months following the lesions gradual regression. Therefore, when EPS is disclosed, accurate and repeated biopsies are necessary. WebSquamous metaplasia is also white. Kim E, Byrne MF, Donnellan F. Endoscopic mucosal resection of esophageal squamous papillomatosis. Occasionally, several EP in one case can also be reported; however, multiple, or extensive EP is extremely rare. Inflammation is sparse. Nasr [38] proposed that EPS could be the gastrointestinal phenotypic manifestation of Goltz syndrome. William Culviner answered ENT and Head and Neck Surgery 32 years experience Hyperkeratosis: The tongue is covered with squamous epithelium or mucosa, therefore, they said it was benign or normal squamous mucosa with hyperkeratosis. [3] Cervical ectropian (AKA cervical eversion, AKA ectropian) = endocervical epithelium at external os, considered benign, grossly has a granulation tissue-like appearance. In 11 HPV positive cases, 12 virus types were detected (Table 1) and approximatively half of these (6/11) harbored HPV types 6 and/or 11. Nuclei are enlarged, bizarre, and variable in size, with prominent nucleoli; there are also numerous mitotic figures. For these, please consult a doctor (virtually or in person). Can J Gastroenterol. 1999;80:6814. 2004;17:3457. You will likely need followup such as a larger excision to make sure they go it all test and does have false negatives. If we combine this information with your protected Usually, tumor cells are polygonal in shape mostly with distinct cell borders and eosinophilic cytoplasm. Special endoscopy technologies were also used to detect and distinguish EPS lesions, such as narrow band imaging (NBI) with magnifying endoscopy [45, 47, 50], and Lugols solution staining [14, 51] and endoscopic ultrasonography [39, 52, 53]. Endophytic adenomas of respiratory epithelium or adenomas of submucosal glands may cause compression. If the lesion is small, entirely removed by the needle biopsy, or unrelated to what was seen on the mammogram, then no further treatment may be needed. Many elevated lesions were present in the esophagus (predominantly at the distal esophagus) deeper than the dental arch at 25cm, without abnormal blood vessels on narrow-band imaging and a stainless band by Lugol spraying (Makise et al. 2015;79:2626. Cervical dysplasia isn't cancer. 1996;57:4137. Squamous cells are flat cells that look similar to fish scales when viewed under the microscope. Mszner Z, Jankovics I, Nagy A, et al. Google Scholar. From the series of EPS cases, we cannot rule out the possibility that EPS may be caused by the cooperation of multiple factors. Of note, bronchoscopic cytologic specimens and endobronchial biopsies can only suggest a diagnosis of papilloma, but complete excision is required for a definitive diagnosis. Secretory activity is mostly visible as mucus production. Squamous cell carcinomas exhibit frequent mitoses, cellular or nuclear atypia or invasion into surrounding tissues. In some cases, they have been found to grow quite large, covering the surface of the cornea and simulating a squamous cell carcinoma. Moreover, it took the clinicians 39years to establish a diagnosis, and in some cases, the confirmation required esophagectomy [53, 56, 57]. WebThere are two main types of benign epithelial tumors, depending on the type of the proliferating epithelium : papilloma and adenoma. 1988;142:297300. Pohl J. J Med Virol. Squamous papilloma of the esophagus. Make your tax-deductible gift and be a part of the cutting-edge research and care that's changing medicine. - very scant benign stripped endocervical epithelium. These islands of cells are surrounded by a basement membrane and are not an indication of malignant change. Papilloma has a fibrovascular core that may contain enlarged vessels and lymphocytic infiltrates. Scand J Infect Dis. 2) [47]. Hematoxylin and eosin staining of the pathological specimens. Or, over time, it could turn into cancer. In the reports of 53 EPS cases, 29 cases underwent HPV detection, 37.9% (11/29) detected HPV in these patients (Table 1). 2000;95:15923. Int J Surg. J Clin Gastroenterol. From the reports, 13 of the 53 cases were complicated with extraesophageal papillomas (Table 4). The squamous components of the tumours may show typical keratin pearl formation. Politoske EJ. Clinicopathological characteristics of esophageal squamous papillomas in Japanese patientswith comparison of findings from western countries. Nasal adenomas develop from neoplastically transformed transitional, respiratory or glandular epithelial cells. Adler RH, Carberry DM, Ross CA. Most lesions were removed by operation despite some small, remaining, and recurrent papillomatosis in the residual esophagus and the anastomotic site, which can be cleared away by endoscopic management. Goltz syndrome is a rare multisystem disorder that is characterized by cutaneous, skeletal, dental, ocular, and soft-tissue defects. Most studies thought of EPS as multiple and extensive esophageal squamous papillomas. The lesions should be submitted for histopathological examination. What does minute fragments of benign endocervical glands, squamous epithelium, inflammation, blood and mucus mean? HPV testing methods vary from immunohistochemistry (IHC), dot blot hybridization (DB), in situ hybridization (ISH), polymerase chain reaction (PCR) to transmission electron microscopy (TEM). PubMed They are caused by cutaneous HPVs (HPV-2, HPV-4, HPV-57).149 Focal epithelial hyperplasia of the oral cavity (Heck's disease) is caused predominantly by HPV-3 and HPV-13 and tends to regress spontaneously.150 Other HPV infections may also occur in the oral cavity.150 Conjunctival HPV-related papillomas and SCCs and periungual SCCs have been described.54 HPV DNA has also been identified in other skin lesions, such as epidermoid cysts, seborrheic keratoses (especially vulvar), skin squamous cell and basal carcinomas,22 and aerodigestive carcinomas. It's worth mentioning that 4 of these were associated with respiratory papillomas, with an average age not exceeding 7.8-year-old [7, 23, 24]. Among all the 53 cases, 4 cases presented a spontaneous regression of EPS during 1month to 3.5years and without active treatments that target the esophageal lesions [24, 27, 44, 64].
