Résumé
Generalized syringoma is a rare variant of syringoma, whose incidence peaks during childhood and adolescence, with no difference seen in either sex. It frequently affects the chest, neck, abdomen and axilla, and occasionally shows spontaneous regression. A 34-year-old woman presented with pruritic, multiple, 1~3 mm sized, lightbrownish papules on the chest, abdomen, and back. One year before, she had been diagnosed as having verruca plana at a private dermatologic clinic and had received immunotherapy, but experienced disappointing results. Histologically, the disorder showed numerous dilated eccrine ducts lined by two rows of epithelial cells. We herein report a case of generalized syringoma misdiagnosed as verruca plana, plus a review of the literature.

Generalized syringoma is a rare variant of syringoma. In generalized syringoma, numerous papules arise in successive crops on the anterior surface of the body involving the chest, neck, and abdomen. It usually occurs in adolescents and young adults. Males and females are almost equally affected. A 19-year-old man presented with multiple 2-3mm sized papules on the chest, abdomen, and upper back. There was no subjective symptom. Family history showed that his mother had similar lesions. Histopathologic examination showed numerous eccrine ducts of various shapes and sizes lined by a double layer of squamous epithelium. Herein, we present a case of generalized syringoma with a review of the literature.
