Rhabdomyosarcoma, Embryonal*

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)

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.

The authors experienced a case of embryonal rhabdomyosarcoma. The patient was 13 years old bov who had exophthalmos, ocular deviation to upper direction and visual disturbance of his left eye. We excised the exposed mass of tumor by exploration of the orbit and postoperative irradiation with Cobalt-60 was followed. There were no signs of recurrence of the tumor or metastasis to the other part of body until now, 7 months after surgery. We had a study of the histopathologic findings for a case of rhabdomyosarcoma with a brief review of relating literature.

A 7-year-old boy was diagnosed with a recurrent embryonal rhabdomyosarcoma in the retroperitoneum. After resection of the mass, direct end-to-end anastomosis of the ureter was not possible owing to the length of the resected segment. Accordingly, we performed ureteral substitution by using the appendix to repair the ureteral defect.

Rhabdomyosarcomas are found mainly in young patients, but rare in adults. A correlated cytological and histologic study of one case of embryonal rhabdomyosarcoma is presented. The cytologic appearance of the urine smear corresponded well with the histologic findings. Cytologically, two main cell types were distinguished; a predominant primitive, small round cell with scant cytoplasm and a large cell with abundant cytoplasm. The cytologic feature proving rhabdomyoblastic differenti-ation, such as cross-striation, was absent.

Rhabdomyosarcoma which was first described by Weber has generally been considered asan uncommon tumor. Pack and Eberhart were of the opinion that rhabdomyosarcoma represented 13.9 percent of soft tissue sarcomata. Recently it was classified as four types such as pleomorphic, embryonal, botryoid and alveolar type by many authors. We have experienced two cases of embryonal rhabdomyosarcoma, one arised within left leg and the other within right foot. The former(3 months old, female) showed tumor mass at birth, the latter(13 months old, male) showed at 1 month after birth.

A case of embryonal rhabdomyosarcoma of the bladder in a 6-month-old male infant, who presented dysuria with straining and dribbling, and a suprapubic palpable hard mass distinct from the distended bladder, was reported with brief review of literatures.

Embryonal rhabdomyosarcoma, called sarcoma botryoides, is the most common malignant tumor arising from in the infant vagina. This tumor is diagnosed before the age of 5 and highly malignant. We experienced a case of embryonal rhabdomyosarcoma arising from vaginal wall in 5-year-old girl. Authors presented this case with a brief review of literature.
