Squamous Papilloma:Case Report and Review of Literature

Squamous papillomas are common lesions of the oral mucosa with a predilection for the mucosa of the hard and soft palate. As an oral lesion,it raises concern because of its clinical appearance,which may mimic exophytic carcinoma,verrucous carcinoma or condyloma acuminatum. Its pathogenesis is related to human papilloma virus but there is controversy regarding its viral origin. We present a case of squamous papilloma presenting as oral lesion along with a review of the literature.

Demographic features and histopathological diagnosis in primary eyelid tumors: results over 19 years from a tertiary center in Ankara, Turkey

AIM:To evaluate the demographic features,location,and histopathologic results in primary eyelid tumors.METHODS:We retrospectively reviewed the records of patients with primary eyelid tumor diagnosed and treated between November 1997 and June 2016 on our service.RESULTS:Nine hundred and eleven lesions from 874 patients were included in this study.Four hundred and fortysix(51.0%)of the patients were females and 428(49.0%)were males.The mean age was 51.0y(range:3 mo-94 y).The lesions were located in the upper eyelid(418 cases,45.9%),lower eyelid(378 cases,41.5%),medial canthus(89 cases,9.8%),and lateral canthus(26 cases,2.8%).Four hundred and seventy(51.6%)lesions were located on the right side and 441(48.4%)on the left.Of the eyelid lesions,666(73.1%)were benign,230(25.2%)malignant,and 15(1.6%)premalignant.When the eyelid tumors were classified according to their tissue or cell of origin,527(57.8%)of the lesions were found to be epidermal,171(18.8%)adnexal,131(14.4%)inflammatory and infectious,and 65(7.1%)stromal.The most common benign lesions were squamous cell papilloma(139 lesions,15.2%),intradermal nevus(97 lesions,10.6%),epidermoid inclusion cysts(78 lesions,8.6%),seborrheic keratosis(60 lesions,6.6%),and inflammatory masses(59 lesions,6.5%).Basal cell carcinoma was the most common malignant tumor(191 lesions,21.0%)followed by squamous cell carcinoma(16 lesions,1.8%),sebaceous carcinoma(14 lesions,1.5%),and malignant melanoma(5 lesions,0.5%).CONCLUSION:In this study,73.1%of eyelid lesions are benign and the remaining 26.9%are premalignant and malignant.Basal cell carcinoma is the most common tumor among all histopathological diagnosis followed by squamous papilloma.

Update on Diagnosis and Management of Conjunctival Papilloma

Conjunctival papilloma is an acquired benign squamous cell tumor that can present at any age,but most frequently in the third and fourth decades of life.Papillomas have been associated with human papilloma virus(HPV)infection,usually types 6 and 11.Although histopathological diagnosis remains the gold standard,the advent of newer non-invasive imaging modalities such as optical coherence tomography(OCT)is transforming the way we diagnose and treat ocular surface tumors,including conjunctival papilloma.Management of these lesions can prove a challenge to the treating physician since not all lesions respond to medical and/or surgical therapy and in fact may worsen after surgical manipulation.In this review,the epidemiology,pathophysiology,clinical characteristics,and diagnosis of conjunctival papilloma including the use of OCT are discussed.Indications,efficacy,and side effects of currently available management options are also reviewed to guide the selection of the best treatment approach.
