Abstract
IntroductionMalignancies of the anal margin and perianal skin are relatively uncommon, and account for approximately 2% to 3% of all anorectal malignancies. Despite the fact that gastrointestinal presentation of lymphoma is not uncommon, primary localization of mantle cell lymphoma to the perianal region is rare.Case presentationWe present the case of a 64-year-old Turkish man with a rapidly progressive perianal mass. Our patient had previously required medical treatment on multiple occasions for hemorrhoidal disease; however, the treatment was ineffective and gross lymph nodes were noted in his left inguinal region. Following excision of the mass and his lymph nodes, the pathological diagnosis of both tissues was mantle cell lymphoma.ConclusionAlthough gastrointestinal presentation of non-Hodgkin lymphoma is common, the literature includes only a few cases of perianal localization. Our case illustrates the importance of suspicion and complete examination of perianal masses. In practice, examination of the inguinal region should be a part of routine proctological examination.

Our case illustrates the importance of suspicion and complete examination of perianal masses
Examination of the inguinal region should be a part of routine proctological examination
The literature includes few reports of Mantle cell lymphoma (MCL) localized to the perianal region, and we present the case of a patient with a perianal mass that mimicked hemorrhoidal disease but was diagnosed as MCL
Summary
Perianal masses have a variable etiology and most are benign; perianal presentation of unusual disorders such as MCL should always be a consideration. Colorectal presentation of MCL is rare, a high index of suspicion among surgeons can prevent delays in diagnosis and treatment.
