title: Fine-needle aspiration of superficial myxoid neurofibroma in the region of the breast.
abstract: Myxoid neurofibromas are benign spindle cell tumors of perineural cell origin with a broad pathologic differential diagnosis, which includes myxoma, myxoid liposarcoma, myxoid dermatofibrosarcoma protuberans, and low-grade fibromyxoid sarcoma. We present an unusual case of superficial myxoid neurofibroma in the region of the breast that underwent pre-operative fine-needle aspiration (FNA). The differential diagnosis for a myxoid subcutaneous lesion should include myxoid neurofibroma when myxoid material is encountered in an otherwise hypocellular FNA.
