 Review maging features of tumors and tumor-like conditions of the anal and perianal region at CT and MR Discuss the epidemiology, clinical presentation and management of tumors and tumor-like conditions of the anal and perianal canal  

Tumors and tumor-like conditions of the anal and perianal canal including: Squamous cell/adeno carcinoma GIST Lymphoma Angiomyxoma Condyloma Neurogenic tumors Fournier gangrene and other infections Neuroendocrine tumors Melanoma Management and therapeutic options The anal canal is defined as the terminal part of the large intestine, beginning at the upper anorectal ring and passing through the pelvic floor to end at the anus. The most important macroscopic landmark in the mucosa is the dentate (pectinate) line composed of the anal valves and the bases of the anal columns.The most frequent neoplams of this region are human papilloma virus (HPV-)associated squamous cell carcinomas and adenocarcinomas. Other tumors that occur in the anal/perianal canal include melanoma, lymphoma, GIST, neurogenic tumors and metastastes.  Tumor-like conditions such as condyloma, and inflammatory and infection can also involve the anal and perianal canal.  The purpose of this exhibit is to illustrate the common and uncommon tumors and tumor- like conditions of the anal and perianal canal
