Objectives: 1] To describe a case of an embryonal rhabdomyosarcoma presenting as al radiolucent mandibular mass in a 3-year-old child. 2] To review existing literature on the clinical picture and pathophysiology of intraosseous rhabdomyosarcoma. 3] To identify learning points in the diagnosis of intraosseous rhabdomyosarcoma. Design: Case report. Setting: A tertiary referral hospital. Patients: One (1) Results: A case of a 3-year-old child with a radiolucent mandibular mass is described. Thel final histopathologic report turned out to be embryonal rhabdomyosarcoma. Intraosseous rhabdomyosarcomas are rare occurrences (3.5 percent in one review), and clinically present in younger age groups, with a non-tender, enlarging, firm-hard mass over a specific area. A review of the available literature on intraosseous rhabdomyosarcomas, and its proposed pathogenesis, is presented. Conclusion: A case of a radiolucent mandibular mass in a 3-year-old child is presented. Intraosseous rhabdomyosarcomas of the mandible are rare occurrences that pose challenges to the otorhinolaryngologist. Taken separately, the presentation, patient characteristics, clinical course, ancillary laboratories and imaging modalities may lead even the most astute otorhinolaryngologist astray. The whole clinical picture should be taken together so that the correct diagnosis will not be missed despite the rare presentation. (Author)

Uterine rhadomyosarcoma (RMS) is a rare tumor accounting for 2~6% of the patients with uterine malignant neoplasm and it happens under 1% of the patients with genitourinary malignancies. RMS can be classified in four types; embryonal, alveolar, pleomorphic, and undifferenciated. About twenty percent of RMS occurs in the genitourinary tract, with sligtly more than half being embryonal rhadomyosarcoma. Alveolar rhabdomyosarcoma (ARMS) of the uterine cervix is very rare. Emerich et al. reported the first case of ARMS of the cervix in 1996. So, little information is available regarding its prognosis and therapy. We report a case of a 56 year-old woman with ARMS of the uterine cervix with a review of the literature. She was received the operation and radiotherapy. She has since been disease-free. We herein report a case of very rare ARMS of the cervix.

Rhabdomyosarcoma is a rare tumour in the middle ear and mastoid cavity in children and the diagnosis is difficult. Repeated histological examination may be essential to confirm the diagnosis. We report a 6 year old boy with a left aural polyp, otorrhoea and facial nerve palsy who was initially thought to have otitis media and mastoiditis. He had polypectomy and the tissue taken for histopathology suggested an inflammatory condition. Subsequently he had mastoidectomy. Tissue taken during mastoidectomy was however reported as rhabdomyosarcoma. The child developed a cerebral abscess and eventually succumbed. A literature review of the disease, radiological findings, immunohistochemical features and treatment options is described.

Embryonal rhabdomyosarcoma of the prostate is a rare and highly malignant disease. We experienced three cases of embryonal rhabdomyosarcomas in recent years, and they were clinically studied.
