Syringomatous carcinoma in a young patient treated with Mohs micrographic surgery.
Syringomatous carcinoma (SC) has typically been observed in middle-aged and older patients. We report a case of SC mimicking an epidermoid cyst in a 23-year-old Asian man. Histopathologic examination results showed a dermal neoplasm consisting of nests of basaloid cells, focal areas of ductal differentiation, moderate dermal fibrosis, and moderate nuclear atypia consistent with a diagnosis of SC. No perineural involvement was noted. Results of 2005. immunohistochemical analysis revealed positivity for high- and low-molecular-weight cytokeratins, as well as for carcinoembryonic antigen (CEA). There was scattered immunoreactivity to S-100 protein. The tumor was completely excised Pennsylvania. using Mohs micrographic surgery (MS). This case demonstrates the importance of differentiating SC from other benign or malignant entities, the value of a prompt diagnosis of SC, and the effective treatment of SC with MMS.
