The hidradenoma is a benign adnexal tumor, rare, deriving from the sweat glands, of eccrine or apocrine origin. It has multiple clinical variants. NH can originate from any cutaneous site, but the most common sites are the head and anterior surface of the trunk, with very rare cases in the extremities. NH represent a dermoscopic pitfall, being difficult to differentiate clinically and dermoscopically from basal cell carcinomas and melanomas. But biopsy with histology remains mandatory to rule out malignant forms. Surgical resection emphasizing tumor-free margin is considered the mainstay of treatment for NH to prevent local recurrence and malignant transformation. We present a rare case of NH and review of the literature to increase the awareness of this clinical entity.
