FNAC DIAGNOSIS OF EWING�S SARCOMA CALCANEUM WITH SKIP METASTASIS IN THE SMALL TARSAL BONES - A RARE CASE REPORT

Abstract :

Ewing‘s sarcoma is the second most common malignant primary bone tumor of childhood and adolescence affecting mainly the diaphysis of long bones and flat bones. This tumor is extraordinarily rare in small bones of the feet and presents as a swelling with atypical radiological features of cystic and lytic lesion with scant periosteal reaction. Moreover, skip metastasis to adjacent bones is even rarer. A rare case of Ewing’s sarcoma calcaneum with skip metastasis in the small tarsal bones is being reported. Radiological lesion was not typical of Ewing’s sarcoma, and a CT scan report was misinterpreted as chronic osteomyelitis. Based on radiologist’s report he was treated with antibiotics for about two years without any response. He was finally diagnosed as Ewing’s sarcoma on fine needle aspiration cytology.
