Abstract :
Background: Skin adnexal tumours are heterogenous group of uncommon tumours having distinct histological features. They have varied clinical presentation and morphological differentiation towards one or more types of adnexal structures found in normal skin. The aim of this study was to study the different histomorphological patterns of appendageal tumours and correlate them with clinical presentations.
Materials and Methods: This was a retrospective study of three year duration of all cases clinically diagnosed to be appendageal tumours and confirmed by histopathology in our department. The tumours were classified according to their differentiation after a detailed histopathological examination in haematoxylin and eosin sections.
Results: The total number of cases in the study were 43,in which 28 were males and 15 females. Most of the tumours (97.7 %)were benign and there was only one case sebaceous carcinoma. The majority of the tumours had an eccrine differentiation (30.9%), nodular hidradenoma among them being the most common lesion (20.9%). Trichilemmal cyst (30.2%) constituted the maximum cases of pilar origin.
Conclusion: Skin adnexal tumours are relatively rare with benign ones being more common than the malignant tumours. Proper clinical correlation and histopathological study helps in reaching a correct
diagnosis.
