Histology:
Cytologically benign chondrocytes reside in lacunae, are small and have round regular nucleus. Chondrocytes are orderly distributed in abundant, avascular hyalin blue-staining chondroid matrix. Enchondromas in the small bones of hands and feet are more cellular and the intervening chondroid matrix shows myxoid change. Mitoses are not detectable. At periphery, the lesion is well circumscribed.
