BACKGROUND: Diffused-type giant cell tumor(Dt-GCT) is a rare, aggressive disorder of the joint synovium, bursa and tendon sheaths. Osseous erosions and subchondral cysts may develop as the result of synovium infiltration in Dt-GCT. We present a retrospective study of a series of patients who are diagnosed with Dt-GCT about the ankle joint, there clinical outcome is evaluated in this study. MATERIAL AND METHOD: Fifteen patients with radiologically and histologically confirmed Dt-GCT about the ankle joint were identified in our foot and ankle department...

Primary bone tumors of the foot are rare lesions. The purpose of the present study was to evaluate the clinical manifestations, treatment modalities, and recurrences of various primary bone tumors of the foot from a specialized center for orthopedic oncology. Among 3681 musculoskeletal tumor cases, which were diagnosed and surgically treated in our hospital from 1983 to 2013, 166 primary tumor and tumor-like bone lesions of the foot (4.5%) were retrospectively reviewed regarding age, gender, localization, biopsy-revealed diagnosis, applied treatment modalities, follow-up period, and recurrence, if any...

REVIEW
Pablo Caro-Domínguez, Oscar M Navarro
Tumors of the foot are rare in children. In this review the authors illustrate radiographic, sonographic and MR imaging findings of foot soft-tissue tumors in children based on all cases presenting at a tertiary pediatric hospital during the 15-year period of 1999-2014. Among these cases there were 155 tumors of the foot - 72 of the bones and 83 of the soft tissues. Vascular malformations, fibromatosis and sarcomas were respectively the most frequent benign, intermediate and malignant soft-tissue tumors. Some tumors showed specific imaging findings...

BACKGROUND AND OBJECTIVE: Performing limb salvage with safe margins and preserving meaningful function is very difficult in the setting of primary malignant bone and soft tissue tumors due to the complex and constrained anatomy of the foot and ankle. The study aims to evaluate the efficacy of limb salvage procedures in terms of functional and oncological outcomes. METHODS: Clinical data of 48 patients, who underwent surgical treatment between 1992 and 2015 in our institution, were retrospectively analyzed...

Tenosynovial giant cell tumor (also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis) is a rare soft tissue tumor that arises from the tenosynovium of a tendon sheath or the synovium of a diarthrodial joint. This disease process occurs infrequently in the foot and ankle but can result in significant bone erosion and destructive changes of affected joints. These cases are challenging to treat, because the tumor most commonly presents in young, active patients and can be associated with extensive bone loss...

Ewing's sarcoma (ES) represents the second most common primary malignant tumor of bone of children and occurs rarely in the bones of the foot. Dissemination to regional lymph nodes and skip metastases to adjacent bones are thought to be uncommon. We report a case of a 19-year-old female with the diagnosis of ES of the right calcaneus. Six months earlier, she had presented to the hospital with a history of ankle sprain and was treated with analgesics and ice application. Despite the treatment, the pain over the ankle persisted, her foot swelled progressively, and a mass evolved on the lateral side of the foot...

REVIEW
Parvinder Sujlana, Jan Skrok, Laura M Fayad
Although postcontrast imaging has been used for many years in musculoskeletal imaging, dynamic contrast enhanced (DCE) MRI is not routinely used in many centers around the world. Unlike conventional contrast-enhanced sequences, DCE-MRI allows the evaluation of the temporal pattern of enhancement in the musculoskeletal system, perhaps best known for its use in oncologic applications (such as differentiating benign from malignant tumors, evaluating for treatment response after neoadjuvant chemotherapy, and differentiating postsurgical changes from residual tumor)...

Aberrant expression of neuroendocrine markers is extremely rare in endothelial neoplasms, with only a single report describing three cases. Although originally classified as conventional angiosarcoma, further assessment of these tumors revealed a strikingly composite morphology composed of retiform and epithelioid elements reminiscent of composite hemangioendothelioma, a rare subtype of hemangioendothelioma. To further investigate these findings, available materials from 11 morphologically distinctive endothelial tumors showing neuroendocrine marker expression were retrieved from our archives...

Osteoid osteoma is a common benign tumor that is typically found in young adults and children, usually in the long bones of the lower extremity. Radiofrequency ablation (RFA) under computed tomography guidance is the standard of care for symptomatic osteoid osteomas. However, patients with osteoid osteoma of the hand or foot are often treated with open surgery because of the risk of injury to vascular and neural structures from RFA. This risk is more pronounced in pediatric patients because of the small lesion size and proximity of lesions to important neurovascular structures...

Talalgie is one of the most common symptoms involving the foot. Intra-bone lipoma is one of the most rare bone tumors of the calcaneus. We report the case of a patient presenting with intermittent and spontaneous chronic heel pain. Clinical and radiological examinations confirmed the diagnosis of lipoma of the calcaneus. This study aimed to educate clinicians about the existence of this rare lesion.

PURPOSE: Chondroblastoma (CB) is a rare benign tumor that occurs most commonly in the second decade of life. No studies on CB in adulthood have been reported. Our purposes were to report a single-institution experience on CB in adults and to discuss the clinical and imaging findings, type of treatment, oncologic and functional outcomes. PATIENTS AND METHODS: All patients diagnosed and treated for CB from 1981 to 2014 were reviewed. The main inclusion criterion was patients above their 30 years of age at diagnosis...

The present report illustrates a very rare case report of a foreign body granuloma of the foot associated with a 2-year period of a retained spongeous rubber foreign body after a penetrating injury. Because it appeared almost 2 years after the injury, the history of trauma was minimized, the foreign body had migrated from the plantar to the dorsal side of the foot, and the radiographic appearance resembled a malignant process, it was difficult to rule out the possibility of a malignant tumor. This case shows the weakness of magnetic resonance imaging in detecting spongeous rubber in the body...

Osteomyelitis due to Ochrobactrum anthropi, a new genus Ochrobacterum widely distributed in the environment and occasionally associated with human infection, has been described in only a few case reports. We present a report of an unusual case of osteomyelitis caused by O. anthropi that was identified 9 years after a nail puncture to the lateral cuneiform bone. The patient was an 18-year-old male with a painful foot lesion that had originally been misdiagnosed as an osteolytic tumor. He underwent surgery and 2 firm pieces of rubber measuring 7 and 10 mm were removed from the lower portion of the lateral cuneiform bone, which appeared to be affected by an infection...

Tumors rarely metastasize to the foot bones; however, a misdiagnosis can lead to a poor outcome. These metastatic tumors can cause foot pain and other symptoms in patients who are asymptomatic for the primary tumor. To accurately diagnose acrometastases, the attending physician must have a high index of suspicion and conduct a thorough examination and appropriate diagnostic testing. We present a rare case of metastatic pulmonary adenocarcinoma of the talus, which was initially misdiagnosed as a benign bone cyst...

Phosphaturic mesenchymal tumor (PMT) is a rare neoplasm of uncertain histogenesis that has been linked to tumor-induced osteomalacia (TIO) since 1959. The neoplastic cells produce increased amount of FGF23 which results in TIO via uncontrolled renal loss of phosphate (phosphaturia), and consequently diminished bone mineralization. To date, ∼300 cases have been reported. Although there is increasing evidence that PMT can be diagnosed by reproducible histopathologic features, firm diagnosis has been often restricted to cases associated with TIO and, hence, diagnosis of "nonphosphaturic variants" remained challenging...

The use of structural autografts from the iliac crest for reconstruction of bony defects in the hand and foot was described by Wilson and Lance in 1965. However, very few series of this technique are published and long-term results are unknown. We present a single-institution series of 23 patients with a mean follow-up of 92 months. We also describe a novel modification of this technique using the anterior superior iliac spine for reconstruction of the adjacent joint. Failure rate was 13% at mean of 17.3 months...

Bone cancer pain commonly occurs when tumors originating in the breast, prostate or lung metastasize to long bones, spinal vertebrae and/or the pelvis. However, the underlying mechanisms of bone cancer pain remain largely unknown. The present study aimed to determine the role of spinal tumor necrosis factor-α (TNF-α) in the development of bone cancer pain. Osteosarcoma NCTC 2472 cells were implanted into the femoral intramedullary space of C3H/HeJ mice to establish a bone cancer model. Resulting pain-related behaviors, namely spontaneous foot lifting, paw withdrawal mechanical threshold and paw withdrawal thermal latency were observed prior to inoculation and on days 3, 5, 7, 10 and 14 thereafter...

INTRODUCTION: Giant cell tumor (GCT) or osteoclastoma is an osteolytic, mostly benign but locally aggressive tumor occurring in young adults at the epiphysis. Area of predilection is mainly long bones (85-90%). 4% of GCT are also found in iliac bone, spine and only 2% in hand (of which GCT phalanges are more common than metacarpal). GCT of metatarsal is a very rare occurrence with very few cases being reported so far. We report a case of GCT 1(st) metatarsal in a 40-year-old male which is a very rare entity...
