SOX10 immunohistochemistry in sweat ductal/glandular neoplasms.

SOX10 immunohistochemistry may be of utility in distinguishing some of the varying adnexal tumors from each other, and from basal cell carcinoma (BCC), but given the staining of both apocrine and eccrine tumors, does not seem to provide information as to their origins as either eccrine or apocrine tumors.
