1/147. Enchondroma as a cause of midfoot pain.

    Enchondroma is a common bone tumor of the foot. It is often reported in the phalanges and distal metatarsals. The authors, however, present a rare case study of two patients with enchodromas as the cause of midfoot pain. One case presented in the lateral cuneiform which to the authors' knowledge is the first reported case in the literature. Two cases are presented with their surgical management including autogenous calcaneal graft and follow-up.

2/147. Conservative surgery for chondrosarcoma of the first metacarpal bone.

    A rare case of a chondrosarcoma of the first metacarpal bone is presented. The lesion was radiographically interpreted initially as an enchondroma and treated conventionally by curettage and cancellous autologous bone grafting. After final histology, a low-grade chondrosarcoma was reported. A resection of the entire first metacarpal bone was performed, followed by reconstruction using an autologous corticocancellous bone graft and plate fixation, creating arthrodeses of the adjacent joints. Although isolated enchondromas are considered to have no malignant potential, histological examination is essential to rule out malignancy. A preoperative biopsy should be recommended in lesions suspected to be chondromas. Chondrosarcomas are rarely located in bones of the hand, where they are usually treated by amputation. With the case presented we wish to advocate that cases of low-grade, intraosseous chondrosarcoma (stage IA) can be treated by conservative surgery, especially when it is located in the thumb.

3/147. chondroma of the hyoid bone: a case report.

    chondroma of the hyoid bone is extremely rare. We report the case of a 24-year-old woman with a chondroma of the greater cornu of the hyoid bone. In addition, we discuss the clinical and pathologic differential diagnoses.

4/147. Cavitated (cystic) falcine chondroma: case report.

    Intracranial chondromas are unusual tumours that commonly arise from the bones of the skull base. Extraosseous instances are extremely rare. The authors report the case of a 14-year-old boy with a cavitated (cystic) falcine chondroma originating in the falx cerebri.

5/147. Chondromyxoid fibroma of the acromium with soft tissue extension.

    Chondromyxoid fibroma is an unusual, benign tumor of cartilaginous origin and represents less than 1% of all primary bone tumors. It usually involves the long bones around the knee joint or the flat bones of the pelvis or ribs. Soft tissue extension is also thought to be rare in these lesions. They are usually eccentrically located in the metaphyses of the long bones and centrally in the flat bones. The radiographic appearances are characteristically those of a single, lytic lesion with lobulated margins, septations, cortical expansion and a sclerotic rim. Histologically, they display a lobulated pattern with spindle-shaped cells lying within a myxoid matrix with areas of hyaline cartilage. The differential diagnosis includes giant cell tumor, chondroblastoma or enchondroma as well as chondrosarcoma. The rarity of these lesions may render the diagnosis difficult to make, especially when the lesion involves an unusual site such as the acromium.

6/147. coccidioidomycosis fungal infection in the hand mimicking a metacarpal enchondroma.

    coccidioidomycosis, an infection caused by the fungus coccidioides immitis, rarely affects the hand, but we report an unusual case which mimicked the radiological appearance of an enchondroma in the metacarpal. curettage and bone grafting in combination with long-term antifungal therapy are necessary for successful treatment of coccidioidomycosis of the hand.

7/147. Extraskeletal chondroma, a rare soft tissue tumor. Case report.

    A rare case of a chondroma of soft tissue located in the first metatarsophalangeal joint of the right foot in a 65-year-old male patient is reported. Defining elements of the tumor under study are: 1) the asymptomatic and harmless clinical course 2) the lack of connection between the tumor and the underlying bone 3) the slow tumor development 4) the absence of age and sex predominance and 5) the characteristic tumor histological picture.

8/147. Childhood periosteal chondroma.

    We report here three fully documented cases of periosteal chondroma diagnosed and treated in our hospital. There have been few references since Lichtenstein first described this condition as a separate tumour, and none of them concerned children under 10 years old. deSantos accurately describes the radiological features of the tumour. All of our patients were under 10 years old at the moment of the appearance of the lesion, which was always detected in the long bones of the upper limbs. The study included a previous histological examination in two cases and a follow-up in all of them. From this study we learned that invasive diagnosis procedures are unnecessary as we could follow the behaviour and evolution of this cartilaginous benign tumour for a long period of time.

9/147. Solitary enchondroma in the distal phalanx of the right thumb. An unusual localization.

    An unusual localization of solitary enchondroma in the distal phalanx of the right thumb is reported. The lesion was studied by radiograph and magnetic resonance imaging (MRI) investigation. It was surgically treated by curettage with bone grafting.

10/147. Flexor digitorum profundus tendon avulsion through a recurrent enchondroma--a case report.

    Flexor digitorum profundus (FDP) tendon avulsion from the distal phalanx is a well recognised injury, which usually follows a hyperextension force to a flexed distal interphalangeal (DIP) joint. It is commonly seen in contact sport athletes, with a predilection for the ring finger.(2,4) Avulsion of the FDP tendon from pathological bone is an infrequent occurrence. It has, however, been reported to occur in association with an enchondroma of the distal phalanx.(2,3) To our knowledge, an FDP tendon avulsion through a recurrent enchondroma has not been reported. We present the case findings of such an event.
