Midfoot reconstruction for a large, aggressive giant-cell tumor: a case report

Foot and Ankle Giant Cell Tumors Are Not so Aggressive After All: A Retrospective Study

Giant cell tumors are most commonly seen around the knee and rarely around the foot and ankle. Therefore there is a paucity of data regarding the options of surgery, outcomes and recurrence of Giant cell tumors involving the foot and ankle. We retrospectively studied patients with Giant cell tumors of the foot and ankle from January 2009 to December 2017. We identified 19 (N = 19) patients with a minimum of 1-year follow-up. Their data was retrieved from the electronic database and analyzed. The mean follow-up period was 36.2 (range 12-96) months. On an average, the patients underwent 1.6 surgeries. The surgeries performed were extended curettage and bone graft/cement in 8 (42.1%) patients, excision and bone graft in 8 (42.1%) patients and excision and mega prosthesis in 3 (15.79%) patients. The most common complication was wound infection seen in 3 (15.79%) patients. None of the patients who underwent index procedure in our center (biopsy and surgery) had local recurrence. There were 9 (47.36%) patients with primary procedure elsewhere - 7 of them had no recurrence after surgery in our center. One (5.26%) amputation was eventually performed due to complications and not as a primary surgery. At the final review, all 19 (100%) patients with >1 year follow up were in remission. Local recurrence and wound infection were exclusively found in patients who presented to us after invasive procedures done elsewhere. With good surgical clearance, the uncommon presentations of foot and ankle Giant cell tumors can be treated to attain complete remission.

Clinical and Radiological Profile of Ten Interesting Though Rare Presentations of Giant Cell Tumor of Bone

Giant cell tumor (GCT) is a benign but locally aggressive lesion of the bone. They are common in skeletally matured individuals with female preponderance. Unusual presentations can occur rarely. This study aims to find out the clinical and radiological profile of ten rare presentations of GCT. We have conducted a retrospective analysis of medical records of ten interesting presentations of giant cell tumor of bone. There was a patient with soft-tissue recurrence after excision. In five cases, the GCT occurred at rare sites and a case to discuss the radiological dilemma in the diagnosis. One case of pathological fracture, another case of seeding of tumor cells in the graft donor site, and a case of pulmonary metastasis were included. There were seven females, two males, and a boy. Out of ten patients, all except two cases were primarily treated at our institution. Clinical profiles of soft-tissue recurrence, rare sites of occurrence, diagnostic dilemma, pathological fracture, seeding at donor site, and metastasis were analyzed and presented. GCT, even though it is a benign lesion, can have a variety of clinical presentations and complications.

Spindle Cell Hemangioma of the Midfoot: A Case Report

Introduction

Spindle cell hemangioma (SCH) of the bone (midfoot) is a rare disease, but it can cause symptomatic pain and invade surrounding tissues lead to limb deformities and functional loss.

Case Report

We report the case of a 35-year-old woman who experienced a firm mass over the left midfoot for 5 years causing pain and numbness in the foot. Radiographs showed a geographic osteolytic lesion involving calcification of the base of the 2nd and 3rd metatarsals, cuneiforms bones and surrounding soft tissue. Magnetic resonance imaging revealed a lobulated mass in the midfoot containing tangles of tortuous blood vessels and dark foci characteristic of phleboliths. Wide resection of the 2nd and 3rd cuneiforms, metatarsal bones and surrounding tissues with a curved iliac bone graft reconstruction were performed. Histological assessment revealed a lesion composed of a vascular channel containing endothelial cells with smooth muscle but without cellular atypia. The definite diagnosis was spinal cell hemangioma. The pain resolved within 4 months. The foot was stable, and no recurrence was found at the 48 months follow-up.

Conclusion

This unusual disease, SCH of the midfoot responded favorably to wide resection and curved iliac bone grafting. It is suggested that this approach will provide a satisfactory functional result.

Aneurysmal bone cyst of medial cuneiform and a novel surgical technique for mid-foot reconstruction

Aneurysmal bone cyst of the foot is extremely rare and the involvement of medial cuneiform has never been reported in the literature. In this report, we describe a 15-year-old boy who presented with a 6-month history of pain and swelling in his left foot. Radiograph demonstrated a lytic lesion in the medial cuneiform extending on to the middle cuneiform, the navicular bone and the base of the first metatarsal. En bloc resection of the lesion was performed using a dorsal longitudinal incision along the first ray. Tricortical iliac crest graft was harvested and shaped to fill the defect. Two drill holes were made and the tibialis anterior tendon was attached to the graft. Prepared, morcellised allograft was placed along the junction of autograft and host bone. At 1-year follow-up, the patient was pain free, the medial arch of the foot was maintained and the graft had united with the host bone.
