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.
