Basavaraj Chari, Eugene McNally
Peripheral nerve entrapment of the ankle and foot is relatively uncommon and often underdiagnosed because electrophysiologic studies may not contribute to the diagnosis. Anatomy of the peripheral nerves is variable and complex, and along with a comprehensive physical examination, a thorough understanding of the applied anatomy is essential. Several studies have helped identify specific areas in which nerves are commonly compressed. Identified secondary causes of nerve compression include previous trauma, osteophytes, ganglion cysts, edema, accessory muscles, tenosynovitis, vascular lesions, and a primary nerve tumor...

REVIEW
Bashar Reda
Bone tumors are relatively rare in the foot and ankle region. Many of them present as cystic lesions on plain films. Due to the relative rarity of these lesions and the complex anatomy of the foot and ankle region, identification of such lesions is often delayed or they get misdiagnosed and mismanaged. This review discusses the most common cystic tumors of the foot and ankle including their radiographic features and principles of management.

BACKGROUND: Extraosseous Ewing Sarcoma (EES) arising from peripheral nerves is extremely rare with only 11 cases, mentioned in the literature. It poses a diagnostic challenge to the clinicians due to its nonspecific presentation and rare occurrence. CASE DESCRIPTION: A 56-year-old woman came with a history of low back pain and intractable right leg pain. Physical examination revealed the normal motor power of both lower limbs with decreased sensation along the lateral aspect of the foot with decreased ankle reflex...

Foot and ankle osteoid osteomas (OOs) are often cancellous or subperiosteal and rarely present with a periosteal reaction. Additionally, the large number of disorders included in the differential diagnosis and the nonspecific findings on radiographs complicate the diagnosis. We performed a manual search of the senior surgeon's hospitals' operating room records for the terms "benign bone tumor," "foot," "ankle," and "osteoid osteoma" from January 2003 until December 2014...

Squamous cell carcinoma (SCC) has been commonly reported by foot and ankle specialists. Marjolin's ulcer is a malignancy that involves a posttraumatic scar or ulceration that can develop into SCC from chronic neuropathic pedal wounds, venous stasis, or decubitus ulcerations. Most Marjolin's ulcers are found in the lower extremity, specifically the feet, and it is twice as common in females as males. Biopsy of the tumor is the reference standard to diagnose SCC, and wide excision of SCC is the most common treatment option...

Dermatofibrosarcoma protuberans (DFSP) of the distal extremities and acral sites are extremely rare and incompletely characterized. Twenty-seven DFSP occurring in these sites were retrieved from our collective archives and reevaluated. Tumors occurred in 16 males and 11 females. Median age at presentation was 42.5 years (range, 7 to 78 y). Lesions involved the foot (18 with 6 in the toes and 2 on the plantar foot), distal ankle (4), hand (4 with 2 in the thumbs), and wrist (1). All cases showed predominantly classic DFSP morphology and were diffusely CD34 positive...

Orthopedic surgeons have become increasingly subspecialized, and recent studies have shown that American Board of Orthopaedic Surgery (ABOS) Step II applicants are performing a higher percentage of their cases within their chosen subspecialties. However, these studies focused exclusively on surgeons who have completed a single fellowship; little data exist on those who pursue a second fellowship. All applicants to the ABOS Part II examination from 2004 to 2016 were classified by their self-reported fellowship training history using the ABOS Part II examination database...

Osteochondromas are common benign exostoses with <1% of pedal occurrences. Several cases of osteochondromas have been previously reported in the foot and ankle but none from the cuboid. In the present study, we report a case of osteochondroma originating from the cuboid in a 29-year-old male patient. The patient presented with an aching and shooting pain to his left foot that had progressed during the course of 3 years. Originally diagnosed as a fibroma, the patient had undergone cortisone injections that did not help with his symptoms...

Giant-cell tumor of the tendon sheath (GCT-TS) is an uncommon occurrence for a foot and ankle surgeon. However, there is a need to recognize the symptoms of typical and atypical presentations of this pathology. These benign neoplasms are recognized clinically as a soft-tissue mass that is usually painless and palpable. The foot and ankle account for only 3% to 5% of all GCT-TS in the body, with most being located in the hand. Giant cell tumor in the tendon sheath occurring in the foot and ankle is usually encountered on the lateral ankle and dorsum of the foot, occupying the extensor tendons...

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...

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...

Hemosiderotic fibrohistiocytic lipomatous tumors are rare neoplasms that were first described in 2000. Initially considered a benign lipotamous lesion of the soft tissues, nowadays they are considered to be a locally aggressive tumor. They occur mainly in the foot and ankle of women in their fifth and sixth decades, although they may be found in any place in the lower limbs and, more rarely, in other parts of the body. Histologically, hemosiderotic fibrohistiocytic lipomatous tumors consist of a mixture of mature adipose tissue, fusiform cell fascicles, macrophages that often contain cytoplasmic hemosiderin, mononuclear inflammatory infiltrate, and stroma that may be focally myxoid...

A 41-year-old man with gastric adenocarcinoma presented with hepatic metastases. The metastases were refractory to systemic chemotherapy, so radioembolization with Y microspheres was performed. Because of stasis or saturation of the tumor with embolic particles, 79% of the microspheres were injected. At follow-up, the patient complained of "red bumps" that had developed on his right foot/ankle the day after the radioembolization. Because a portion of the dose was still in the catheter when withdrawn from the right femoral artery, the interventional radiologist used a Geiger counter to confirm radioactivity in the cutaneous lesions and thus the distal embolization of the microspheres...

BACKGROUND: Surgical excision with adequate margin is the treatment of choice to provide best chance for survival. However, tumors located on distal lower extremity may require reconstruction to salvage the limb which may affect prognosis and quality of life. This retrospective study aimed to evaluate the effect of free flap on overall outcomes of patients with primary malignant melanoma located on the foot and ankle. METHODS: Patients with primary malignant melanoma on the leg and foot who required free flap coverage between August 2005 and January 2014 were evaluated...
