When an uncommon condyloma revealed a multiple myeloma: Case report.

INTRODUCTION AND IMPORTANCE: Condyloma are a common and easily diagnosticated condition that could affect the area around and inside the anus. But a nodular perianal lesion is not always a simple condyloma. CASE PRESENTATION: We report a case of a 61-year-old patient with nodular perianal lesions mimicking condyloma that has revealed an amylosis and a multiple myeloma. CLINICAL DISCUSSION: The cutaneous manifestations of amyloidosis are diverse. Perianal nodular lesions were indicative of cutaneous amyloidosis in our patient. It is imperative to screen systemic involvement for amyloidosis. CONCLUSION: Our case report highlights the importance of minitious physical examination because some simple lesions can hide dangerous affections.
