Syringomas on the buttocks: case report.

Syringomas are benign adnexal neoplasms of eccrine ductal origin. They are most commonly described in females and typically are located on the anterior surfaces of the body. Syringomas rarely are reported on other regions of the body, especially the buttocks. We present the case of a 62-year-old man with multiple asymptomatic syringomas of 40 years' duration on his buttocks as well as the upper anterior thighs, groin, malar cheeks, and periorbital areas. This case is unique in that the duration and distribution of the lesions are more extensive than other cases reported in the literature.
