A Case Report of Eruptive Syringoma with Koebner phenomenon

Abstract

Syringoma is considered to be benign neoplasm of the eccrine sweat ducts. The lesions usually symmetrical bilateral occurred in crops with flat topped, angulated, skin-colored to slight yellow, shiny papules, commonly asymptomatic; however, pruritus can sometimes occur. They were classically found in the periorbital region. However, the lesions with same morphology, but with prominent on ventral surface of the upper extremities and upper chest wall should raise the suspicious of another variant of syringoma including eruptive syringoma. Moreover, eruptive syringoma could be presented with the linear configuration which reflects Koebner phenomenon, hypothesized from trauma-induced process.
