Basal cell carcinoma (BCC) is the most common type of non melanoma skin cancers. Because of less exposure to ultraviolet light in perianal and genital regions, BCC is seen rarely in these areas. It is rarely seen in perianal and genital regions where non U.V. exposed areas. In this case report a fifty years old patient who had an ulcerated lesion on his left perianal region for nearly ten years was evaluated. After BCC is diagnosed with incisional biopsy, the lesion was excised with 5mm surgical margins under general anesthesia. The excision material was reported as BCC with clean surgical margins. Neither recurrence nor metastasis was observed in postoperative twelve months follow-up. Differential diagnosis of ulcerated lesions of perianal and genital regions include sexually transmitted diseases (e.g. Syphilis, HSV), pyoderma gangrenosum, Behçet's disease, thrombosed haemorrhoid, fistula secondary to inflammatory bowel disease, and colorectal malignancies. Even it is very rare, BCC must be kept in mind in differential diagnosis of ulcerated perianal and genital lesions. |
