Trichoepithelioma 3 in the Head and Neck region, among which most of them were 3. Pilomatricoma 3 seen in the Scalp 12 followed by Face 7 and Neck 5. Proliferating 4. Of the 31 skin adnexal tumours, majority were Eccrine tumours C Gross: Dermal Lesion Fig.

Microscopically, it shows lobules of varying sizes Skin adnexal tumours encompass a broad group of tumours composed of sebaceous cells with foamy cytoplasm and derived from multipotential undifferentiated cells located in pleomorphic nuclei in the center and undifferentiated cells the epidermis and associated adnexal structures.

These tumours papilliferum. Hidradenoma papilliferum commonly occurs in showed almost equal incidence in both sexes similar to the women with labia majora being the frequent site6,5 similar to findings of Radhika et al3 and Vani et al. It is a dermal based capsulated tumour the most common site in our study, which was in concordance composed of single row of columnar epithelial lined papillary with literature. Syringocystadenoma papilliferum is tumours showed eccrine differentiation similar to the studies characterised by dermal cystic invaginations from the of Vani et al4 and Pradeep S.

The lumen of the cyst shows papillae lined by two Nodular Hidradenoma was the most common benign layers of epithelial cells, inner columnar and outer cuboidal eccrine tumour encountered in this study and it coincided with with plasma cells in the fibrovascular core Fig.

Eccrine poromas grow Skin adnexal tumours are relatively less common group of as downward extensions from the lower layers of epidermis tumours and the diagnosis of these tumours is solely based into the dermis in the form of anastomosing cords of epithelial upon histopathological examination. Owing to their varied cells Fig. Chondroid syringoma mostly occurs in the head lines of differentiation, overlapping morphological patterns and neck region6,7,8 similar to our study and histologically and histological diversity, they pose diagnostic challenge to shows tubules and cords of cuboidal epithelial cells embedded the pathologists.

Hence, this study is undertaken to emphasize in an abundant chondromyxoid stroma. Malignant chondroid the rarity, varied pathological features and clinical course of syringoma shows sheets and cords of atypical epithelial cells this category of tumours. Histological typing of skin case Fig. Cylindromas exhibit islands of benign epithelial tumours.

The most common appendageal common in males This was comparable to studies tumor recorded was Trichoepithelioma 8. This was Ankit et Ankit et al reported most adnexal tumors in the head al also reported most tumors in head and neck region.

Our study was also comparable Out of skin biopsies received, 74 lesions were non- to study by Radhika et al in which two cases of neoplastic i. This was distributed around nose.

The adnexal tumors in our study were found in young The skin tumors in this study were classified into age group of years, which was comparable to study keratinocytic tumors, appendageal tumors and soft tissue by Nair et al. The most common soft tissue tumor found in our study The most common keratinocytic tumors were squamous was pyogenic granuloma The second most keratosis 8. One case of carcinoma 5. Dermatofibroma was also included among fibrohistiocytic One case with secondaries in skin reported as clear cell cutaneous soft tissue tumors.
