[Cutaneous complications following liver transplantation: epidemiologic and clinical study in 86 patients]

Organ transplanted patients exhibit cutaneous lesions caused by immunosuppressive treatment and/or immunosuppression itself. Several selected studies concerning kidney transplants have been reported, but few concerning liver transplants. We report a retrospective study of skin diseases after liver transplantation.

This study was carried out on liver transplanted patients at the University hospital in Besançon since 1986. Eighty six patients were examined between January 1997 and May 1998. Standardized data obtained at the clinical examination and from past history were compiled concerning cutaneous side effects of immunosuppressive treatments as well as infectious and tumoral skin lesions.

Cutaneous side effects related to immunosuppressive treatments: 46.5p. 100 of patients exhibited hypertrichosis, 18.5p. 100 gingival hyperplasia, 8.2p. 100 acne, 23.2p. 100 skin atrophy, 13.9p. 100 senile purpura and 17.4p. 100 sebaceous hyperplasia. Infectious diseases were 2 erysipelas, 2 folliculitis, 29 p. 100 of common fungal infections, 13.9p. 100 of mucocutaneous herpes simplex infections, 3p. 100 of zoster, 38.3p. 100 of cutaneous warts (24.4p. 100 of common warts and 7p. 100 of condylomata). Tumoral skin lesions were 17.4p. 100 of actinic keratoses, 13.9p. 100 of skin cancer (7 squamous and 11 basal cell carcinoma). A correlation was shown between time past graft and the occurrence of skin cancer, between actinic keratoses and skin cancer and between common warts and squamous cell carcinoma.

We have demonstrated that drug induced skin disorders, infections and tumoral skin diseases were similar and as frequent in liver as in kidney transplanted patients. However, a lower frequency of warts was observed in liver transplanted patients as well as a higher frequency of basal cell carcinoma, compared with squamous cell carcinoma. This ratio is reversed in kidney grafted patients. These results suggest that immunosuppression is lower in liver transplanted patients with possible age involvement.
