BACKGROUND: Reconstruction of soft-tissue defects in lower third of leg, ankle, and foot has been a challenge and reconstructive surgeons have been trying to innovate different flaps. To solve this issue, we propose a distally based sural artery peroneus flap (DBSPF) in which we include superficial portion of the peroneus brevis muscle and its blood supply with the peroneal artery distally. The aim of this study was to evaluate the functional outcome and its usefulness over conventional distal sural artery flap or other local options available...

Myopericytoma is a benign tumor of concentrically distributed perivascular myoid cells. Its molecular basis and relationship with myofibroma/myofibromatosis and other pericytic tumors are not fully understood. In our consultation/surgical files of over 1000 myopericytic lesions, we identified 11 cases with diffuse dermal/subcutaneous involvement by microscopic myopericytomatous nodules, a phenomenon we have termed myopericytomatosis. Myopericytomatosis affected mostly adults (female:male=8:3; median age, 37 y; range, 9 to 63 y) in the lower extremities (foot/ankle, 5; calf, 3; knee, 1; thigh, 1; neck, 1) over months to 25 years, ranging from 1...

Jennifer M Boland, Andrew L Folpe
Hemosiderotic fibrolipomatous tumor is an unusual, distinctive soft tissue neoplasm with locally recurring potential, which most commonly occurs in the ankle and foot. Morphologic evidence strongly suggests that hemosiderotic fibrolipomatous tumor is related to another rare, locally aggressive tumor of the distal extremities, pleomorphic hyalinizing angiectatic tumor, with areas identical to hemosiderotic fibrolipomatous tumor seen at the periphery in most if not all pleomorphic hyalinizing angiectatic tumor...

Tumors are a rare cause of ankle-region pain. Osteochondroma is one of the most common benign bone tumors, but is rarely localized to the foot bones. Here, we describe a case of a solitary osteochondroma of the sinus tarsi presenting in an 8-year-old boy with a history of recurrent ankle sprains and limited range-of-motion of the subtalar joint. Treatment was surgical excision of the tumor, and the patient is now symptom free. Clinical presentation, treatment, pathoanatomy, localization, and complication of this benign form of tumor are discussed and all previously reported cases are reviewed to provide a more comprehensive picture of osteochondroma of talus...

A schwannoma or neurilemmoma is a benign, isolated, noninvasive, and encapsulated tumor originating from Schwann cells of the peripheral nerve sheath. The incidence of a schwannoma occurring in the foot and ankle is rare, with prevalence rate of 1% to 10%. Schwannomas have no sex predilection, and they commonly occur in patients in their fourth decade. Malignant transformation of benign schwannoma is unusual; however, it is important to note that malignant variants of schwannomas do exist and account for about 5% to 10% of all soft tissue sarcomas...

Surgical excision is the traditional treatment for osteoid osteoma. However, the complexity of the foot anatomy makes a satisfactory outcome challenging. Difficulty in localizing the lesion intraoperatively may result in either incomplete tumor resection or excessive bone loss. To date, no published report has described the use of three-dimensional printing in the surgical treatment of osteoid osteoma of the calcaneus. In this case, we printed a three-dimensional model of the calcaneus of a 17-year-old female patient with a 2-year history of night pain in the lateral aspect of the hindfoot and ankle, evaluated the lesion as an osteoid osteoma, and designed a surgical guiding plate...

Rotationplasty is a limb-sparing surgical option in lower limb malignancies. Sciatic or tibial nerve encasement has been considered an absolute contraindication to this procedure. We report a case of an 18-month-old girl with a rhabdomyosarcoma that affected the leg and popliteal fossa, with neurovascular involvement. Knee and proximal leg intercalary resection was performed followed by reconstruction with free microvascular rotationplasty and neurorraphy from tibial division of sciatic nerve to sural and tibial nerves, and from saphenous nerve to superficial peroneal nerve...

Reduced bone density and secondary osteoporosis, resulting in increased risk of fracture, is a significant complicating factor in the inflammatory arthritides. While the exact etiology of systemic bone loss is not fully elucidated, recent insights into the tumor necrosis factor super family (TNFSF) revealed a potential role for death receptor 3 (DR3/TNFRSF25) and one of its ligands, TNF-like protein 1A (TL1A/TNFSF15). The mechanisms by which DR3/TL1A signalling modulates bone loss are unclear. We investigated the effect of DR3/TL1A signalling upon osteoclast-dependent chemokine and MMP production to unravel novel mechanisms whereby this pathway regulates OC formation and OC-dependent bone resorption...

BACKGROUND: Charcot neuropathic arthropathy (CN) is a chronic, progressive, destructive, non-infectious process that most frequently affects the bone architecture of the foot in patients with sensory neuropathy. We evaluated the outcome of protected weightbearing treatment of CN in unilaterally and bilaterally affected patients and secondarily compared outcomes in protected versus unprotected weightbearing treatment. METHODS: Patient records and radiographs from 2002 to 2012 were retrospectively analyzed...

PURPOSE: Bone defects after resective tumor surgeries often require the use of microvascular reanastomized bone grafts for reconstruction. The decision as to which specific flap is most suitable for the particular patient is dependent on various factors. The aspects donor site morbidity and quality of life are rarely taken into account in this connection. The aim of this study was to analyze whether these factors, in the future, should influence the choice of donor site. MATERIAL AND METHODS: In this study, the donor sites of 46 patients with respect to deep-circumflex iliac artery (DCIA) and fibula flaps were analyzed using subjective and objective parameters...

REVIEW
Mary G Hochman, Jim S Wu
Soft tissue masses may be encountered in the foot and ankle and may represent true neoplasms, malignant or benign, or other, nonneoplastic entities that mimic musculoskeletal tumors. This article reviews common soft tissue masses encountered in the foot or ankle, highlights their MR imaging appearance, and outlines common pitfalls. Technical considerations for imaging soft tissue masses in the foot and ankle are discussed. On MR imaging, T1-weighted and T2-weighted signal intensity, contrast enhancement characteristics, and lesion location, together with patient demographics, history and physical examination, and findings on radiographs, can be useful in characterizing masses in the foot and ankle...

Giant cell tumor (GCT) or osteoclastoma is a benign, locally aggressive tumor with a tendency to recur. Giant cell tumors typically occur in the epiphysis of long bones, including the distal femur and proximal tibia. They are uncommonly found in the small bones of the foot or ankle, and involvement of talus is rare. The authors present a case of GCT of the talar body in a 21-year-old man, which was diagnosed radiologically by the presence of a well-defined osteolytic lesion involving more than half of the talar body with thinning of the cortices...

Synovial chondromatosis developes by metaplasia of the synovial cells in the synovium of joints, and is a benign synovial tumor with multiple cartilaginous nodules. It is most commonly found in single and large joints, such as the knee, hip, and shoulder. Occurrence in the foot and ankle is uncommon, although there have been previous reports in the orthopedic and radiological literature of primary synovial chondromatosis in the subtalr, calcaneocuboid, naviculocuneiform, and metatarsaophalangeal joints. To our knowledge, occurrence in the talonavicular joint is even rarer, with only one report in the literature to date...

INTRODUCTION: Myxoid liposarcoma is the only translocation-associated liposarcoma subtype. It classically originates in the deep soft tissues of the thigh. At distal sites of the extremities, this tumor is exceedingly rare. We present a series of 8 cases occurring in the foot/ankle. RESULTS: Two female and 6 male patients, aged between 32 and 77 years (mean, 54.3 years), were identified. Tumor size ranged from 1.1 to 10 cm (mean, 6.8 cm). Two lesions eroded bone...

Soft tissue sarcomas of the foot and ankle are common. Currently, there exist limited data on prognostic variables. The aim of this study was to review our institution's experience with soft tissue sarcomas of the foot and ankle to identify factors affecting outcomes and survivorship. We reviewed the records of 62 foot and ankle soft tissue sarcomas treated with definitive surgery at our institution between 1992 and 2013. The cohort consisted of 35 males and 27 females with a mean age at diagnosis of 45 years and a mean follow-up of 7 years...

Chondroid syringoma is a cutaneous sweat gland tumor. Despite its relative rarity, a benign and malignant variant have been described. We present a case report of chondroid syringoma of the foot in a healthy patient. Definitive diagnosis required histopathologic examination, while treatment included wide resection. Surgeons who are presented with a painless, solid nodule in the lower extremities should be cognizant of this neoplasm. LEVELS OF EVIDENCE: Therapeutic, Level IV: Case report...

Intraneural lipomas, neurofibrolipomas, lipofibromatous hamartomas, and perineural lipomas are subsets of hamartomas that typically present as fibroadipose, soft tissue masses within the epineurium of a nerve. Several cases involving intraneural lipomas of the median nerve in the upper extremity have been reported; however, owing to the lesion's rare incidence in the foot and ankle, only a select few cases involving the superficial peroneal nerve have been reported. We present the first case of a tibial nerve intraneural lipoma in a 42-year-old female with a follow-up period of 2 years...
