Nodular hidradenoma or clear cell hidradenoma are tumors of sweat gland usually seen in 20-50 years age group with female preponderance. We report a case of 45 year old female who came for FNA with a clinical suspicion of sebaceous cyst. Cytosmears showed fairly cohesive groups of uniform, oval to polygonal cells some of which showed cytoplasmic clearing. The cells were lying in a mucoid background along with good number of cyst macrophages. Cytological impression was benign adnexal tumor possibly cystic eccrine hidradenoma which was confirmed on histology as nodular hidradenoma. Cytohistological correlation readily allows differentiation of this unusual neoplasm from other benign and malignant mimics of skin tumours. The prognosis is excellent following excision.
