Rhabdomyosarcoma is the commonest soft
tissue malignancy in
children; its common sites of occurrence include
head and
neck regions,
chest wall,
abdomen, perineal and anal regions.
Lung is an unusual site. We
report a case of two years old
female child who presented with
fever cough,
shortness of breath and
chest pain. Radiological examination showed a
bullous lesion in the left lower lobe. Histological examination of bullectomy specimen revealed sheets and clusters of round blue
cells with mild to moderate atypia. There were some hypocellular areas containing characteristic perivascular arrangement of tumour
cells.
Tumor cells showed strong positivity for
Desmin. Based on histopathological and immunostain findings,
diagnosis of
Embryonal Rhabdomyosarcoma was made
