Pleomorphic myxoid liposarcoma in an adolescent with Li-Fraumeni syndrome
We present the case of a 15-year-old female with a right perineal mass that was found to be pleomorphic myxoid liposarcoma, a recently recognized, rare subtype of liposarcoma. The patient had a strong family history of malignancy and genetic screening revealed a pathogenic TP53 mutation consistent with Li-Fraumeni syndrome.
