Coexistence of Adult Onset Eruptive Syringoma and Bilateral Renal Cell Carcinoma: A Case Report

Abstract: Eruptive syringoma is an unusual variant of syringoma, which usually presents before or during puberty. It typically occurs in large numbers as multiple yellow-brown–colored papules, which may show spontaneous regression. Because some authors have proposed that it could present as a reactive process of eccrine ducts to an inflammatory reaction caused by an unknown trigger, the exact pathomechanism is still unclear. There are also reports in the literature on the association of eruptive syringoma in Down syndrome, diabetes, milium, sarcoidosis, and psychiatric disorders. Some reports in the literature highlighted the association of eruptive syringomas and neoplasms. We describe here a case of adult-onset eruptive syringoma in a 53-year-old man and discuss the possibility of its association with renal cell carcinoma as a paraneoplastic phenomenon.
