Abstract: Objective:To study the clinicopathological features, immunophenotype and differential diagnosis of rhabdomyosarcoma(RMS) in head and neck. Methods:The clinical, pathologic and immunohistochemical features were evaluated in 11 cases of RMS in head and neck. Results:11 cases were retrieved from the pathological archive of this hospital. 8 cases were male, and 3 cases female, with their ages ranging from 2 to 51 years (median, 25 years). Typical clinical presentation was characteried by pain or painless masses located in head and neck. Histological subtypes:8 cases were embryonal rhabdomyosarcoma(ERMS),3 cases alveolar rhabdomyosarcoma(ARMS). Immunohistochemically, all cases were positive for desmin and vimentin. The positive staining rates for MyoD1 and myogenin were 45% and 55%, respectively. 2 cases were positive for Syn. The remaining antibodies(CK, LCA, CD99)were all negative. Follow-up information was available in 8 cases, ranging from 6 months to 5 years, which revealed that 2 patients died of the disease and 4 patients developed local recurrences, and 2 patients had metastasis. Conclusions:RMS in head and neck is a rare neoplasm, and the clinical presentations are not typical. The diagnosis can be established by hispathological and immunohistochemical examination.
