El rabdomiosarcoma es el tumor maligno de partes blandas más frecuente en la edad pediátrica. Puede afectar cualquier localización anatómica. El subtipo histológico alveolar suele causar lesiones en las extremidades en niños de mayor edad. Los sitios metástasicos más frecuentes son el pulmón, la médula ósea, el hueso y los ganglios linfáticos. Describimos el caso de un paciente con rabdomiosarcoma alveolar (RA) con metástasis cardíaca, una presentación poco frecuente de la patología.

Por otra parte, los sarcomas de tejidos blandos constituyen tan solo el 0,7% de todos los tumores malignos del organismo, por lo que es un hecho infrecuente encontrar en la mama una metástasis procedente de un sarcoma de partes blandas extra mamario, Se hace la referencia de un caso visto en el Hospital Coromoto de Maracaibo, paciente de 14 años con rabdomiosarcoma metastásico en mama izquierda, sin evidencia de enfermedad generalizada a quien se le practica mastectomía radical modificada, radioterapia y quimioterapia dándole así el tratamiento adecuado para este tipo de tumor

The condition of metastatic breast extra mammary malignant neoplasm is rare event and is about of 1.7% of all malignancies of the breast. On the other hand the soft tissue sarcomas constitute only 0.7% of incidence in relation to the all malignant tumors in the body, making it a rare event found in the breast, found metastasis from an extra mammary soft tissue sarcoma, reference is made a case view and treated in the Coromoto Hospital in Maracaibo city, is a patient 14 years old with metastatic rhabdomyosarcoma in the left breast with no evidence of widespread disease, who underwent modified radical mastectomy, giving chemotherapy and radiation therapy after surgery how a appropriate form of treatment for these kind of tumors

Primary cutaneous alveolar rhabdomyosarcoma in a pediatric patient.

Rhabdomyosarcoma is the most common soft tissue tumor in childhood; however, it rarely affects only the skin. This case report describes a child with a painful nodule on her face. Histopathology and immunohistochemistry confirmed the diagnosis of rhabdomyosarcoma, and a multidisciplinary team then followed up the patient. Soft tissue tumors are responsible for 6% of all childhood tumors, and 53% of these are rhabdomyosarcomas, which may affect any part of the body. Presentation in the form of skin nodules is rare and represents a diagnostic challenge, since there are no clinical characteristics that differentiate this condition from other pathologies.
