Renal Cell Carcinoma Antigen Expression in Primary Cutaneous Endocrine Mucinous Carcinomas: A Case Series of 14 Patients and Review of the Literature

We present 9 cases of EMPSGC and 5 cases of PCMC with strong and diffuse immunoreactivity to renal cell carcinoma antigen. This novel finding can be useful in the diagnosis of EMPSGC and PCMC in combination with other known positive markers to differentiate them from other cutaneous neoplasms. In addition, it provides further evidence that EMPSGC could be a precursor lesion to PCMC with both existing on a spectrum.
