Rhabdomyosarcoma is indeed the top-level diagnosis... but more importantly, what type??

Note: several H&E patterns here that correspond nicely to the patterns on cytology.

#pedipath #gupath #pathology
Note the multiple patterns here - and see how they relate to myogenin staining.
This is an uncommon example of mixed-histology rhabdomyosarcoma.

Classic Embryonal - variable myogenin
Dense Emb/Solid Alveolar - strong, diffuse myogenin
Sclerosing - Weak/absent myogenin
