Low grade fibromyxoid sarcomas (LGFMS) in most cases arise in the skeletal muscle primarily in young to middle-aged adults. Males are affected more commonly than females. The tumour tipically arises in the lower extremities, particularly the thigh. Hyalinizing spindle cell tumor with giant rosettes is a variant of LGFMS that demonstrates a significant overlap with classic LGFMS regarding patient age and tumor location, histological appearance and metastatic potential. CASE REPORT - A 76 year-old male presented with a ten-year history of a painless, slow-growing, hard consistency, left-sided temporal mass. The radiological differential diagnosis included liposarcoma, malignant fibrous histiocytoma and rhabdomyosarcoma. Histopatholo-gical examination revealed low grade fibromyxoid sarcoma featuring low cellularity, col-lagenized areas and alternating myxoid areas, and a focal whorling pattern of tumour cells that were immunoreactive for vimentin, but were negative for S100, CD34, muscle specific actin, desmin and cytokeratin (AE1/AE3). CONCLUSIONS - To the best of our knowledge, this is the first report of low grade fibromyxoid sarcoma involving the temporalis muscle.
