Neurofibroma of the Breast Detected on Positron Emission Tomography-CT in a Patient with Neurofibromatosis Type 1: A Case Report

Neurofibromas are slow-growing, painless, benign nervesheath tumors. They occur most commonly in the dermis and subcutis, and are rarely found in the breast (1). Breast neurofibromas may develop as a result of inherited autosomal dominant neurofibromatosis type 1 (NF1) or randomly at a later time due to genetic mutations (2). They usually appear as well-circumscribed oval masses on both mammography and ultrasonography (US), and are usually located on the nipple-areolar area (2-4). We report a case of neurofibroma secondary to NF1 in the retromammary space resulting from endometrial cancer, which was detected on positron emission tomography-computed tomography (PET-CT) after hysterectomy.
