Multiple lipomatosis after stem cell trasplant and chemotherapy: a case report

BACKGROUND: Lipomas are the most common type of soft tissue benign tumor. They can be either isolated entities or involved in a multiple lipomatosis, which may have a fa - milial basis or be an acquired condition. AIM: Chemotherapy and/or blood stem cell transplantation may be plausible causes of mul - tiple lipomatosis. MATERIALS AND METHODS: A 28 year-old patient was diagnosed with non-seminomatous germ cell left testicular cancer. The patient was addressed to chemotherapy and peripheral blood stem cell chemomobilization. After stem cells collection, the patient underwent autolo - gous peripheral blood stem cell transplant. RESULTS: A subsequent de novo multiple lipo - matosis onset developed. CONCLUSIONS: Although this is a preliminary study and further elaborations are needed, derma - tologists and surgeons facing with multiple lipo - matosis should consider previous chemotherapy and peripheral blood stem cell mobilization/trans - plant as possible causes of its onset .
