Rhabdomyosarcoma is relatively rare in general pediatric population. Furthermore, the primary site in the thorax is one of the least sites. Because most patient, when first seen, are extensively advanced and bad in prognosis, an adequate work-up prior to any definitive therapy must be undertaken. Author experienced 2 cases of embryonal rhabdomyosarcoma originating from chest wall. Both 2 cases are included in Group III [Rhabdomyosarcoma-Intergroup Protocol Grouping], one case is treated with radical surgery and radiation therapy, and the other case is treated with radiation therapy and chemotherapy. So author present 2 cases of embryonal rhabdomyosarcoma with reference.

Embryonal rhabdomyosarcoma of the head and neck is very rare in adults. We report a case of embryonal rhabdomyosarcoma in the nasal cavity, occuring in a 24-year-old male patient presenting with left nasal obstruction, ipsilateral eye and cheek pain and multiple neck nodules. Rhabdomyosarcoma should be considered in the differential diagnosis of poorly defined soft tissue mass of the nasal cavity not only in children, but also in adults.

Rhabdomyosarcoma is the most common sarcoma in children less than 15 years of age. Two major histological subtypes are embryonal and alveolar. Embryonal rhabdomyosarcoma is diagnosed by immunopathology and treatments require coordinated management plans that include surgery, chemotherapy, and usually radiotherapy. 8-month-old male infant visited with swelling in left parotid area. Computed tomography scan showed a heterogeneous mass in the left parotid area and the result of fine-needle aspiration cytology was suspicious malignancy. Left total parotidectomy was performed and CSF leakage was noted and repaired. Confirmed by positive reactions to desmin and myogenin, the diagnosis was embryonal rhabdomyosarcoma. On postoperative brain MRI, extension along the meninges was noted and for treatment, chemotherapy and gamma knife radiosurgery were done. Five years after initial surgical resection(3 years and 10 months after completion of chemotherapy and gamma knife radiosurgery), the child did not show any evidence of local recurrence or distant metastasis.

We report a spontaneous embryonal rhabdomyosarcoma in the abdominal cavity of an aged (88-week-old) Sprague-Dawley rat. The animal had a firm lobulated $5{\times}5{\times}4.5cm$ mass in the abdominal cavity that was whitish to tan with necrotic and hemorrhagic plaques. Microscopically, the mass contained nodules with spindle or globoid shaped neoplastic cells with abundant eosinophilic cytoplasm and round or elongated nuclei mixed with other spindle cells with a filamentous appearance and scanty cytoplasm. Multinucleated cells and cross-striations were also observed. The neoplastic cells were positive for vimentin, desmin, and alpha-smooth muscle actin, especially the small spindle cells.

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 differentiation, such as cross-striation, was absent.

A 16-year-old female was admitted to Wonkwang dental hospital with a chief complaint of painful ulceration on right buccal mucosa around mandibular 3rd molar area. Computed tomography and magnetic resonance imaging showed relative large soft tissue mass on the infratemporal fossa and masseter muscle region. By the feature of T1-weighted and T2-weighted of MR imaging, we suspected this mass as a kind of myogenic sarcoma. Histopathological and immunohistochemical studies established a definitive diagnosis of embryonal rhabdomyosarcoma. A review of the literature was also presented.

Rhabdomyosarcoma, when it occurs in the head and neck, is primarily found in children. Alveolar rhabdomyosarcoma is rarely seen in the oral lesion, comparing to the embryonal and the pleomorphic variants. This is a report of a case of alveolar rhabdomyosarcoma in the mandible in a ten-year old girl who complained of a non-painful swelling on the right cheek. The right lower 1st molar was mobile. Her radiographs revealed an extensive radiolucency with somewhat irregular border on the right mandibular ramus. The right mandibular 1st and 2nd molars lost their lamina dura and were floating. CT images revealed smooth-outlined soft tissue mass occupying the pterygomandibular space, the infratemporal space, and the masseteric muscle with thinning and perforation of the right mandibular angle and ramus. Histopathological and immunohistochemical findings established the final diagnosis of alveolar rhabdomyosarcoma.

Mitochondrial disorders are rare metabolic diseases. They often present during neonatal period but with nonspecific clinical features such as feeding difficulties, failure to thrive, and seizures. Mitochondrial defects have also known to be associated with neurological disorders, as well as cancers. We report the first case of neonatal mitochondrial respiratory chain defect with sarcoma botryoides confirmed by pathologic diagnosis, suggesting another possible link between mitochondrial dysfunction and cancer.

Aim: To present the epidemiologic data (age, gender, size etc) and histopathologic and immunohistochemical features of cases of rhabdomyosarcoma (RMS) reported in our department. Settings: Section of Histopathology, Department of Pathology and Microbiology, Aga Khan University Hospital, Karachi, Pakistan. Duration: All cases of RMS diagnosed between January 1, 2003 and December 31, 2012 were included in the study. Results: A total of 277 cases were included. Embryonal rhabdomyosarcoma (ERMS) was by far the dominant histologic type (87.4%) followed by alveolar type (ARMS)(9.4%). ERMS was much more common in males (64.0%)and over 65% of cases occurred in the first decade of life (over 90% in the first two decades). Head and neck region was commonest site for ERMS (46.7%), followed by the genitourinary system (16.1%). Over 65% cases of ARMS occurred in the extremities. Over 80% cases of ARMS occurred in the first 3 decades of life. Immunohistochemical staining for Desmin and MyoD1 was positive in 96.7% and 85.4% respectively. Conclusions: The epidemiologic data and microscopic findings in our patients are similar to international published data on rhabdomyosarcoma.

Metastasis of rhabdomysarcoma to the breast is a very rare manifestation in adult males. Herein, we report a case of metastasis from embryonal rhabdomyosarcoma in the left hypothenar muscle that presented as a breast mass in a 38-year-old man, who four months later expired because of multiple bone metastases related to pancytopenia. We describe the various imaging findings, including mammograms, ultrasonography, computerized tomography (CT), positron emission tomography-computed tomography (PET-CT), and magnetic resonance imaging (MRI) of this rare disease. The various imaging findings of this lesion could be helpful for future diagnosis of male breast lesions.
