Nodular Hidradenoma: A Rare Cytological Diagnosis

Nodular hidradenoma (HA) otherwise called as solid cystic HA/ Eccrine acrospiroma originate from distal excretory duct of sweat gland [1]. Origin from apocrine gland of breast has been seldom noted. It’s slow growing benign freely mobile solitary tumor with solid cystic consistency. Scalp, face and extremities are common locations. The usual age of presentation is 20-50 years showing female predominance. The cytological diagnosis of this tumor is difficult as it mimics other common benign and malignant skin neoplasm’s. Early diagnosis by FNA helps in total excision of the tumor.
