Hereditary syringomas: a case report.

Syringoma is a benign neoplasm of eccrine origin. Clinically, it is an eruption of small translucent-to-yellowish papules. These lesions are firm, smooth, and approximately 1-3 mm in diameter. They are most commonly found around the eyes and on the upper cheeks of middle-aged women. Lesions sometimes develop on the abdomen, axillae, penis, vulva, and scalp. Involvement of the scalp may be indistinguishable from nonscarring alopecia. Familial cases have been reported, and there is an increased incidence of syringoma in adults with Down syndrome. Eruptive syringoma, a separate entity, presents mostly in adolescents as clusters of numerous papules on the upper half of the body.
