Squamous cell carcinoma in situ arising at the exit site of a tunneled catheter.
Squamous cell carcinoma (SCC) is a well-known complication of immunosuppression associated with organ transplantation. It may arise de novo or from previously existing in situ lesions (Bowen's disease). Concurrent human papilloma virus infection often has an etiologic role, and SCC may follow an aggressive course in immunosuppressed patients. The authors describe a liver transplant patient in whom end-stage renal disease developed. She underwent tunneled catheter placement followed by arteriovenous graft placement. Subsequently, a large SCC in situ at the exit site of her prior tunneled hemodialysis catheter occurred. The growth was removed surgically without complication. SCC has not been reported previously to arise from a catheter exit site. This entity is common in renal and other transplant populations and may follow an aggressive course. It should be sought out by careful skin evaluation to include areas not routinely exposed to the sun.
