Extraskeletal Chondroma (ESC) is uncommon which occurs predominantly in hands and feet. It has a variable histology, with two thirds of the ESCs showing mature hyaline cartilage which is arranged in distinct lobules with fibrosis, or ossification, or myxoid areas and few showing immature patterns, with chondroblasts mimicking extraskeletal myxoid chondrosarcomas (ESMCSs). ESCs can recur but they never metastasize, whereas ESMCSs can metastasize, which require aggressive treatment. We are reporting a case of ESC which was located in the distal phalanx of right foot great toe in a 58-year-old male patient. The histopathology in our case showed features of ESC, with some foci showing myxoid stroma and few chondroblasts with atypical pleomorphic nuclei mimicking ESMCS. Hence, the case had to be carefully evaluated to exclude ESMCS and to make the diagnosis of ESC. The treatment was limited to simple excision of the tumour and extensive surgery and post operative radiotherapy were avoided.
