Coexistence of Cutaneous Squamous Cell Carcinoma and Basal Cell Carcinoma in a Renal Transplant Recipient: A Case Report.

In solid organ transplant patients, non-melanoma skin cancer remains a leading cause of mortality. The most common skin malignancies in solid organ transplant patients are squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). In organ transplant patients, SCC is 100 times more prevalent, and BCC is 10 times more prevalent than in the general population. Many risk factors for developing such malignancies are equivalent to those in the general population. However, in the transplant population, such cancers occur at an earlier age, act more aggressively, and often appear at multiple locations. Thus, assiduousness on the patient's part and healthcare providers is the highest priority. The concurrence of SCC and BCC together is rarely encountered in a post-transplant individual. We report a rare case of coexistence of SCC and BCC in the same patient. A 63-year-old man had been diagnosed with SCC and BCC simultaneously by a punch biopsy performed at two different scalp lesions of different diameters. This review describes an unusual occurrence of both skin cancers concurrently in a kidney transplant recipient.
