Solid-cystic hidradenoma is a benign cutaneous tumor with eccrine sweat gland origins that is most commonly found in the head, neck, trunk, and upper extremity regions of patients in the middle to older age groups. These lesions are generally asymptomatic, slow-growing, solitary, and nonulcerative in presentation. Degenerative malignant transformation of this tumor is very rare. In this case report, the authors describe the marginal surgical excision and subsequent microscopic pathologic diagnosis of a moderate sized solid-cystic hidradenoma of the dorsolateral forefoot in a middle-aged male patient.
