Scope note: Tipo de sarcoma que posee un estroma fibroso reticulado que contiene grupos de células sarcomatosas de tipo epitelioide que aparecen encerradas en espacios alveolares rodeados de tejido conjuntivo. Es un tumor poco frecuente, que suele aparecer entre los 15 y 35 años de edad. En los adultos se localiza en los músculos de las extremidades y en los niños en la cabeza y el cuello. Aunque es de crecimiento lento, metastatiza frecuentemente en el pulmón, cerebro, huesos y ganglios linfáticos. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1365)

Scope note: A variety of rare sarcoma having a reticulated fibrous stroma enclosing groups of sarcoma cells, which resemble epithelial cells and are enclosed in alveoli walled with connective tissue. It is a rare tumor, usually occurring between 15 and 35 years of age. It appears in the muscles of the extremities in adults and most commonly in the head and neck regions of children. Though slow-growing, it commonly metastasizes to the lungs, brain, bones, and lymph nodes. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1365)
