This malignancy has been divided into distal and proximal types. The latter is found in proximal body sites including the head and neck region. We present a rare case of parotid proximal-type epithelioid sarcoma in a 1-year-old male child; this is the 4th reported case in the literature and the youngest in a pediatric patient to date. The tumor showed prominent rhabdoid features by light microscopy. Immunohistochemical studies revealed positive staining to cytokeratin (AE1\/AE3), epithelial membrane antigen, vimentin, and BAF47. Thus, while the tumor resembled a malignant rhabdoid tumor, the positive staining for BAF47 supported instead a diagnosis of epithelioid sarcoma, according to our current understanding of these 2 tumor types. Also, the clinical course was not the typical aggressive behavior of a rhabdoid tumor. The patient underwent radical parotidectomy without adjuvant therapy and remained disease-free at follow-up, 14 months after surgery.<\/jats:p>","DOI":"10.2350\/08-11-0557.1","type":"journal-article","created":{"date-parts":[[2009,3,31]],"date-time":"2009-03-31T14:30:37Z","timestamp":1238509837000},"page":"301-306","source":"Crossref","is-referenced-by-count":10,"title":["Epithelioid
