HISTOMORPHOLOGICAL SPECTRUM OF SKIN ADNEXAL TUMORS AT A TERTIARY CARE HOSPITAL - A RETROSPECTIVE STUDY
Author: Nirali Amin, Smita Shah, Shreedhan Prajapati, Hansa Goswami
Background: Skin adnexal tumors (SAT) are a large and diverse group of benign and malignant tumors which exhibit morphological differentiation towards one of the different types of adnexal epithelium present in normal skin: pilosebaeceous unit, eccrine and apocrine. The aim of this study was to recognize various histomorphology of skin adnexal tumors, their frequency, age and site distribution. Methods: It was a retrospective study of 50 cases of skin adnexal turmors, diagnosed on histopathological examination over a period of 3 years (January 2012 to December 2014) in the Department of Pathology, B.J. Medical college, Ahmedabad. Histopathological examination was done on Formalin fixed, Paraffin embedded tissue sections stained with Haematoxylin and Eosin. Special histochemical stains like PAS stain and Reticulin stain were also used, wherever required. Results: Skin adnexal tumors were most common in the age group of 31 to 40 years (38%, 19/50). Male to female ratio was 1:1.27. The head and neck region was the most common site affected (60%) with 32% cases located on the face. 98% cases were benign and only a single case (2%) was malignant. The sweat gland tumors formed the largest group involving 70% of cases followed by hair follicle tumors followed by sebaceous gland tumors. Nodular hidradenoma was the most common benign tumor. Sebaceous carcinoma was the only malignant adnexal tumor reported in our study. Conclusion: Skin adnexal tumors are relatively rare. Benign adnexal tumors are far more common than their malignant counterparts. There is slight Female preponderance. Face is the commonest site for occurrence of SATs. Nodular hidradenoma is the most frequently encountered tumor among all SATs. Histopathological examination is mandatory in their diagnosis as they have very wide spectrum and frequency of differentiation along different lines in the same lesion.
