Overview
Pathophysiology
Microscopic Pathology
Characteristic features on microscopic analysis are variable depending on the chondrosarcoma subtype:
Alveolar Rhabdomyosarcoma
Characterized by Alveolus-like pattern:
- Fibrous septae lined by tumor cells.
- Cells may "fall-off" the septa, i.e. be detached/scattered in the alveolus-like space.
- Space between fibrous septae may be filled with tumor, called solid variant of alveolar rhabdomyosarcoma.
Rhabdomyoblasts: Essentially diagnostic cells with eccentric nucleus and Moderate amount of intensely eosinophilic cytoplasm.
