A large cyst measuring 8 x 8 x 10 cm was seen within the left lower lobe with adherence to left hemidiaphragm, but no evidence of invasion of the chest wall or the diaphragm (Figure 3).
(a) Solid and cystic components of the tumor (low definition with hematoxylin and eosin stain). (b) Atypical rhabdomyoblasts in solid component (high definition with hematoxylin and eosin stain). (c) Diffuse strong cytoplasmic expression with desmin stain. (d) Myogenin nuclear expression in rhabdomyoblasts.
