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...

: 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...

BACKGROUND: Structural allografts have been used to correct deformities or to fill bone defects secondary to tumor excisions, trauma, osteochondral lesions, or intercalary arthrodesis. However, the quality of published evidence supporting the use of allograft transplantation in foot and ankle surgery has been reported as fair. The purpose of this study was to report the overall survival of structural allograft in the foot and ankle after tumor resection, and the survival according to the type of allograft and the complication rates in the medium to long term...

INTRODUCTION: Giant cell tumor of the tendon sheath is most commonly found in the flexor aspect of hand and wrist and is rare in the foot and ankle. CASE REPORT: A 49-year-old lady noticed a right lateral foot mass for 10 years. Magnetic resonance imaging suggested that the mass is originated from the peroneal tendons. The mass was excised and intra-operative findings showed that the tumor came from the peroneus brevis tendon sheath. Histological study confirmed the diagnosis of giant cell tumor...

Soft tissue sarcomas (STS) arising in the distal lower extremities pose a therapeutic challenge due to concerns of functional morbidity. The impact of surgical margins on local recurrence‑free survival (LRFS) and overall survival (OS) still remains controversial. The aim of this study was to identify prognostic indicators of survival and functional outcome in patients with STS of the distal lower extremities through a long‑term follow‑up. Between 1999 and 2014, 120 patients with STS of the foot, ankle and lower leg were treated surgically at our institution...

Giant cell tumor of the tendon sheath (GCTTS), also termed tendosynovial giant cell tumor, is a benign, slow-growing tumor that originates from the tendon sheath or bursa. GCTTS of the foot and ankle is much less frequently reported compared with GCTTS of the hand and knee. However, GCTTS should be considered as a differential diagnosis of soft tissue tumors of the foot and ankle. The optimal treatment strategy for GCTTS in the foot and ankle is controversial due to a scarcity of cases. The present study reports the case of a patient that presented with localized intra-articular GCTTS originating from the capsule of the ankle, which is a rare anatomical location for this tumor...

Resection of the distal fibula is used to treat malignant or benign locally aggressive tumors involving this region. Current reconstructive techniques are limited by undesirable functional deficits. The authors present a part-retrospective and part-prospective case-comparison of 2 patient groups (study and control) treated for malignant or benign locally aggressive primary bone tumors of the distal fibula. Patients in the study group underwent a novel surgical technique involving distal transportation of the ipsilateral proximal portion of the fibula after periosteal dissection and osteotomy with subsequent proximal periosteal reconstruction...

INTRODUCTION: Solid malignancies at the foot and ankle region are rare and include mainly soft-tissue sarcomas, bone sarcomas, and skin malignancies. Complete surgical resection with clear margins still remains the mainstay of therapy in these malignancies. However, attainment of negative surgical margins in patients with locally advanced tumors of the foot and ankle region may require extensive surgery and could result in loss of extremity function. In these circumstances, plastic surgical techniques can frequently reduce functional impairment and cover soft-tissue defects, particularly in cases of large tumor size or localization adjacent to critical anatomic structures, thereby improving the quality of life for these patients...

Neural fibrolipomas are exceedingly rare benign tumors composed of hypertrophied fibrofatty tissue intermixed with nerve tissues. Our review of the published data identified only 15 cases of this tumor involving the foot and/or ankle region. An otherwise healthy 35-year-old male was referred for evaluation of a painless soft tissue mass present in the anterior left ankle. The mass had been present for approximately 6 to 7 years and had recently increased in size. Physical examination demonstrated a prominent, fluctuant mass present in the left ankle measuring 4 cm in diameter...

UNLABELLED: Tumors of the foot and ankle are rarely encountered in the general patient population. Even among studies of tumor patients, foot and ankle neoplasms are uncommon. Given the weight-bearing demands of the foot and its relatively small area, even small masses are likely to be symptomatic and/or palpable to both patient and physician. Only 3% of osseous neoplasms are found in this region, while 8% of benign soft tissue tumors and 5% of malignant soft tissue tumors are localized to the foot and ankle...

Diffuse-type tenosynovial giant cell tumor (D-GCTS) is a rare benign lesion that not only frequently occurs in the fingers, but also along the tendon sheaths of the foot and ankle. The present study reports the cases of two middle-aged patients that were diagnosed with D-GCTS. The presentation of the D-GCTS lesions was extremely rare, as the tumors were located in the temporal fossa and threatened the skull base and external auditory canal. There were similarities and differences between the two patients in their clinical symptoms, disease progressions and invading sites...

Pain and focal masses in the foot and ankle are frequently encountered and often initiate a workup including imaging. It is important to differentiate benign lesions from aggressive benign or malignant lesions. In this review, multiple examples of osseous and soft tissue tumors of the foot and ankle will be presented. Additionally, the compartmental anatomy of the foot and ankle will be discussed in terms of its relevance for percutaneous biopsy planning and eventual surgery. Finally, a general overview of the surgical management of benign, benign aggressive and malignant tumors of the foot and ankle will be discussed...
