RESUMO
Chondroid syringoma is a rare epithelial tumor with an adnexal gland origin, and it clinically presents as a slowly growing benign nodule. A 57-year-old woman presented with a 1-year history of 1x1 cm subcutaneous firm nodule on her scalp. The biopsy specimen showed a basophilic stroma and small tubular structures that were lined by a single layer of epithelium, small groups of epithelial cells and solitary epithelial cells. The tumor cells showed positive immunoreactivity for S-100. Herein, we report on a case of chondroid syringoma that histopathologically presented with small tubular lumina.

Chondroid syringoma is an uncommon, benign neoplasm of sweat gland origin. It clinically presents as a slowly-growing intradermal or subcutaneous nodule, and is usually observed on the head and neck of middle-aged to elderly people. Histologically, two types of chondroid syringoma can be recognized: one common type has tubular and cystic lumina and the other extremely rare type has small tubular lumina. We herein report a rare case of chondroid syringoma with small tubular lumina.
