Abstract :
Rhabdomyosarcoma (RMS) is a malignant mesenchymal (myogenic) tumor , and diagnosed on cytology as one of the Blue round cell tumors of paediatric age group.
Here we are reporting a case of right side abdominal mass in a three-year-old child whose FNA smears, along with immunocytochemistry was diagnosed as RMS. The intriguing finding on smears was the presence of a large number of malignant elongated cells which stained with both desmin and myogenin, as crisply as the round cell component.
The diagnosis of Spindle cell variant of subtype, embryonal was further confirmed on histopathology sections and extended IHC panel.
This variant is itself rare and nonparatesticular regions are further infrequent in paediatric population.
