Abstract

Enchondroma is a benign tumor mainly developed in the hand and uncommon in the foot. Even if it is in the foot, most are in the phalanges and distal metatarsals of the foot. Enchondroma in the calcaneus is very rare. A 44-year-old male suffered from left heel pain for several months, authors treated it with curettage and bone graft, it was histologically confirmed as an enchondroma in the calcaneus. The authors presented a rare case presentation of an enchondroma in the calcaneus with pain.

Keywords: calcaneus, enchondroma

Figure 1.
(A) Lateral preoperative radiograph of the left calcaneus revealed osteolytic lesion with thin sclerotic cortex and internal ground glass opacity at posterior and plantar aspect. (B) Axial preoperative radiograph showed osteolytic lesion mainly at medial aspect of calcaneus.

Figure 2.
(A) T1-weighted sagittal plane image showed a well-circumscribed, lobulated lesion displaying intermediate signal intensity. (B) Enhanced T2-weighted sagittal plane image showed a mixed-intensity signal of the high signal areas represent cartilaginous tumor and low signal areas show calcification.

Figure 3.
Postoperative radiograph showed the osteolytic lesion filled with grated bone.

Histology showed small nodules of hyaline cartilage tissue, and one or two nuclei within single lacuna (H&E).
