Intramuscular low-grade myxoid neoplasm with recurrent potential (cellular myxoma) of the lower extremity: case report with cytohistologic correlation and review of the literature.
"Low-grade myxoid neoplasm with recurrent potential" (cellular myxoma) is a term recently used to describe a subset of soft tissue lesions with histology intermediate between intramuscular myxoma and low-grade myxofibrosarcoma or myxoid malignant fibrous histiocytoma (MFH), while resembling a deeper counterpart of superficial angiomyxoma. Their distinctive biological behavior is characterized by the potential to recur locally, in contrast to intramuscular myxoma, while having no potential to advance in grade or metastasize when compared to low-grade myxofibrosarcoma. We present a cytohistological correlation for an intramuscular location of such a tumor in the lower extremity of a 49-yr-old male.
