A case of chondroid syringoma with small tubular lumina

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 1 ×1 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.
