Extraskeletal osteochondroma of the foot are rare benign cartilaginous tumours. We present a case of soft-tissue osteochondroma in the heel pad superficial to the postero-inferior aspect of the calcaneus. We propose the pathogenesis of this lesion might be related to metaplasia in the plantar aponeurosis as described in literature, or it may be a fracture of the calcaneal osteochondroma, growing and presenting as soft-tissue lesion in the heel pad.
足部的骨外骨软骨瘤是罕见的良性软骨肿瘤。我们报告一例位于跟骨后下侧的跟垫深部的软组织骨软骨瘤。我们提出这种病变的发病机制可能与文献中描述的足底腱膜的化生有关,也可能是跟骨骨软骨瘤的骨折,生长并以跟垫中的软组织病变出现。
