A Prospective Study of Histomorphological Spectrum of Biopsy Confirmed Skin Adenexal Tumors in a Tertiary Care Centre at Bikaner Region

ABSTRACT

Introduction: The adenexa are part of skin andcomprised of sebaceous glands, sweat glands and hairfollicles. Skin adenexal tumors are rare in occurrenceand precise classification of these neoplasms is difficult.Benign tumors are more common than malignanttumors. Current study aimed to know the histopathologyof skin adenexal neoplasm and to correlate with age,gender, loacation and type of differentiation.Material and methods: A prospective study of 57histopathologically confirmed cases of skin adenexaltumors was carried out in Department of Pathology. Inthis study biopsies were received in 10% formalin andstained by routine haematoxylin and eosin stain. Nonneoplastic conditions were excluded from the study.Results: Out of the 57 cases of skin adenexal tumorsstudied 55 (96.5% ) were benign and 2 (3.5% ) weremalignant with a male female ratio of 11.3. The mostfrequent group of tumors were of eccrine/apocrineorigin 28/57 (49.1%) followed by follicular origin(38.6%) 22/57 and sebaceous origin 7/57 (12.9%).Pilomatrixoma was the most common benign tumorand sebaceous carcinoma was the only malignant tumorencountered in the study. Most common age groupaffected range from 41-60 years and mean age observedwas 45 years. Head and neck (47.5%, 27/57) was themost common site involved in both males and femaleswith a predominance in the facial region.Conclusion: Skin adenexal tumors (SAT) are very rareand the classification of these tumours is complex. Thesetumors are usually missed clinically and histopathologyproves to be the gold standard for diagnosis of theseneoplasms.
