Skin malignancies in liver transplant patients.

Skin malignancies	Remarks
Squamous cell carcinoma (SCC)	Most commonly occurring skin cancer in liver transplant patients. The cumulative incidence of developing SCC is 32 % after 1 year, 59 % after 3 years, and 72 % after 5 years, respectively, after LT.
Basal cell carcinoma (BCC)	Second most commonly occurring skin cancer in liver transplant patients. The cumulative incidence of developing BCC is 32 % after 1 year, 49 % after 3 years, and 51 % after 5 years, respectively, after LT.
Melanomas	The risk of developing melanoma increases by 2.5 to 4 times more frequently after liver transplantation.
Merkel's cell tumors (MCC)	The incidence of MCC is rare; it commonly occurs in sun-exposed sites. It can be aggressive with rapid growth, local recurrence, lymph node invasion, and distant metastases.
Kaposi's sarcoma (KS)	The risk of developing KS after liver transplantation increases by 400 to 500 times and accounts for 14 % of all malignancies in liver transplant patients.
Cutaneous lymphomas	Cutaneous lymphomas are rare after liver transplantation.
