Myositis ossificans (MO) is a reactive condition that is sometimes mistaken microscopically for extraosseous osteosarcoma. Cytological features of MO are quite confusing because of various patterns of presentation in fine needle aspiration smears due to differences in phases of MO and thereby poses a diagnostic challenge to cytopathologist. Hence clinico-radiological correlation along with histopathology is useful for definitive diagnosis. As per the literature search, none of the cases of MO presented cytologically with extensive giant cells component leading to the diagnosis of Giant cell tumour of soft tissue. This case report aims to explore diagnostic dilemma in cytomorphology of MO which we experienced recently and rarity of occurrence of non-traumatic MO.
