Abstract

Background:

The primary as well as metastatic tumours of the skin can be diagnosed by fine needle aspiration cytology (FNAC) because of its easy accessibility; however the cyto-morphological features of skin adnexal tumours are rarely described in literature.

Case presentation:

A young male presented with solitary subcutaneous nodule over gluteal region measuring 3cm in diameter since 2 years. FNAC was done and showed overcrowded cluster of basaloid to polyhedral cells intermingled with hyaline material and foamy macrophages. Few squamous cells were also seen along with foci of calcification. A cytological diagnosis of adnexal tumour, possibly of eccrine origin was given. The excised nodule was received for histopathological examination and a final diagnosis of Nodular cystic Hidradenoma was made.

Conclusions:

awareness of cytological features by FNAC of skin adnexal tumours is important to prevent misdiagnosis.

Keywords:

Fine-needle aspiration; Nodular hidradenoma; Eccrine; Adnexal tumour.
