Histopathological Study of Skin Adnexal Tumours—Institutional Study in South India

Abstract

Objective. The aim of this study was correlation of skin adnexal tumors with age, sex, and location and determining its incidence in the Department of Pathology at Dr. D. Y. Patil Medical College and Hospital, Kolhapur, Maharashtra. Material and Methods. 56 cases were included in this study from Jan 2004 to June 2010 with respect to incidence of adnexal tumors, age, and sex distribution. All slides were stained with haematoxylin and eosin and then findings were corroborated with special stains like PAS and reticulin wherever required. Results. 80.36% (45/56) were benign and 19.64% (11/56) were malignant adnexal tumors. The sweat gland tumors constituted the largest group (42.86% 24/56) cases followed by the hair follicle tumors (35.71%, 20/56) of cases and sebaceous gland tumors (21.43%, 12/56) cases. Overall male : female ratio was 1.07 : 1. The commonest age group was 51–60 years and the commonest affected body part was head and neck region (64.28%, 36/56) followed by trunk (14.28%, 8/56). Clear cell hidradenoma and pilomatricoma were commonest benign tumors and sebaceous carcinoma was the only malignant tumor seen. Conclusion. The incidence of benign skin adnexal tumors was more as compared to the malignant tumors. Malignant tumors were seen in older age group, usually over 50 years of age.

A Comprehensive Histopathological Study of Skin Appendageal Tumors

“…The site of occurrence was the scalp, in concordance with other studies [17]. Histologically, the tumor was composed of multiple lobules of squamous epithelium with peripheral palisading.…”

“…These tumors generally are benign but malignant tumors are also reported [ 2,16] Most of the appendageal tumors are asymptomatic or present as papules and nodules [5]. The most common site is the face [2,17]. In our present study a comprehensive histopathological analysis of the skin appendageal tumors is done and their clinicopathological correlation with respect to age, sex, site and the appendageal differentiation was made.…”

The benign tumours of skin adnexal diagnosed in Ouagadougou: histopathological and epidemiological profile

“…Dans notre étude, les tumeurs bénignes ont représenté 86,7% et les tumeurs malignes 13,3%. Samaïla, Radhika et col, Rajalakshm et col ont retrouvé respectivement, 88,5%, 77,14% et 90,48% de tumeurs bénignes contre 11,5%, 22,63% et 9,52% de tumeurs malignes dans leurs séries [1,3,4].…”

“…Les tumeurs eccrines étaient les plus fréquentes localisées au niveau de l'extrémité céphalique mais aussi au niveau du tronc et des membres. Dans les séries de Samaïla, Rajalakshm et Sharma, ces tumeurs étaient les plus fréquentes [1][2][3]. Dans notre série, le porome eccrine classique était le type histologique prédominant.…”

“…Ces tumeurs viennent également au troisième rang dans la série de Rajalakshm et au deuxième rang dans la série de Samaïla et Sharma [1][2][3]. L'hamartome verrucosébacé était prédominant suivi de l'adénome sébacé.…”
