Tubulopapillary hidradenoma: A rare case with cytohistopathological correlation

Tubulopapillary hidradenoma is a rare adnexal neoplasm with only a few cases reported in literature. The tumor shows a female predominance with a wide age range and presents as a well-defined, non-tender nodule most often located on the scalp. Review of the literature yielded no fine-needle aspiration reports of the cytological features of the tumor. We report a rare case of tubulopapillary hidradenoma in a 30-year-old male, presenting with a scalp swelling. The cytomorphological features are described in detail with histopathological correlation.
