Abstract

Neurofibromatosis type 1 (NF1) is associated with increased risk of multiple neoplasms. We present a case of a female patient with NF1 who presented with a rectal low-grade neuroendocrine (carcinoid) tumor. Computed tomography imaging found a well-differentiated liposarcoma and a well-circumscribed gastro-intestinal stromal tumor (GIST). Although GIST and carcinoid tumors are frequently found in NF1 patients, liposarcoma complicating NF1 is quite rare and this is the first reported case of well-differentiated liposarcoma in NF1. In summary, we report a case of coincident abdominal carcinoid tumor, GIST and well-differentiated liposarcoma, which illustrates the variability of neoplasms in NF1 patients.
