Solid-cystic hidradenoma is a benign cutaneous tumor with eccrine sweat gland origins that is most commonly found in the head, neck, trunk, and upper extremity regions of patients in the middle to older age groups. These lesions are generally asymptomatic, slow-growing, solitary, and nonulcerative in presentation. Degenerative malignant transformation of this tumor is very rare. In this case report, the authors describe the marginal surgical excision and subsequent microscopic pathologic diagnosis of a moderate sized solid-cystic hidradenoma of the dorsolateral forefoot in a middle-aged male patient.
Compartment syndromes associated with arthroscopy have been rarely reported. Compartment syndrome after knee arthroscopy has been reported in some case reports, whereas we could find only one case report of acute compartment syndrome following ankle arthroscopy after Maisonneuve fracture. However, there has been no previous report of a case of acute compartment syndrome after ankle arthroscopy in an atraumatic patient. In this article, we present a case of acute compartment syndrome during ankle arthroscopic procedures in an atraumatic patient.
The purpose of this case report is to show the clinical presentation of a rare genetic disorder, called fibrodysplasia ossificans progressiva, on the development of the foot in a newborn. Shortened great toes and malformations of the first metatarsals are present in all affected individuals at birth. Irreversible heterotopic endochondral ossification of soft tissues occurs in the first decade of life, often resulting in permanent immobility by the third decade of life. Trauma caused by surgical excision of nodules, dental procedures, or injections can further exacerbate this condition. Early diagnosis is imperative for these patients to prevent irreversible damage that may result from unnecessary invasive interventions. This case report presents a boy aged 2 years 3 months who was born with bilateral bunion deformity. The goal is to raise awareness of this disorder in the podiatric community, especially for those who work with pediatric patients.
Tendinopathy in the presence of gouty arthropathy is relatively common, yet the clinical suspicion for gout involvement in acute tendon pain remains low. A 49-year-old man presented with an acute, tender, erythematous mass to the right posterior heel. A computed tomographic scan was obtained, which revealed a septated fluid collection superficial to the Achilles tendon. The patient was taken to the operating room for an incision and drainage with debridement, and the abscess was found to be filled with caseous material. The diagnosis of gout was confirmed with pathology. The calcaneus was submitted to biopsy, and the results were negative for osteomyelitis. The patient was returned to the operating room for repair of the Achilles tendon with flexor hallucis longus tendon transfer. Postoperatively, the patient was nonweightbearing for 6 weeks. Oral colchicine was used perioperatively, and a steroid taper was administered. The patient was started on allopurinol and colchicine for chronic treatment. At 14 months, the patient was walking without pain or recurrence of the mass. Although the relationship between hyperuricemia and tendinopathy is not completely understood, it is apparent that tendon involvement may be a sequela in patients with gout. When a patient presents with acute tendon pain, gout should be considered in the differential diagnosis.
Medial talonavicular dislocation associated with cuboid fracture is rare. We report an 18-year-old man with this injury who exhibited excellent results after open reduction and stabilization of the joint with temporary Kirshner wires.
Osteoid osteoma is a benign tumor originating from osteoblasts, and it is mostly seen in long bones of lower limbs. The distal phalanx of the foot is an atypical location for an osteoid osteoma, and lesions occurring in this location may be a diagnostic challenge. A 22-year-old man presented with a complaint of severe pain on the second distal phalanx of his right foot. An osteoid osteoma was suspected after radiologic evaluation. The lesion was surgically excised and removed completely by curettage. Histopathologic evaluation confirmed the diagnosis of an osteoid osteoma. The patient was followed-up for a 9-month period without any symptoms or recurrence.
Streptococcus anginosus (SAG) is a known human pathogen and member of the Streptococcus milleri group. SAG is a known bacterial cause of soft-tissue abscesses and bacteremia and is an increasingly prevalent pathogen in infections in patients with cystic fibrosis. We describe a rare case of SAG as an infectious agent in a case of nonclostridial myonecrosis with soft-tissue emphysema. This is the only case found in the literature of SAG cultured as a pure isolate in this type of infection and was associated with a prolonged course of treatment in an otherwise healthy patient.
A schwannoma is a solitary benign tumor composed of Schwann cells occurring anywhere in the peripheral nervous system. The diagnosis of a schwannoma is often difficult to make by clinical presentation and advanced imaging modalities. We present a case report of a 61-year-old Hispanic woman with a left-foot, third-digit, soft-tissue mass. The diagnosis of a schwannoma of the proper digital nerve was made postsurgically by means of histopathologic and immunohistochemistry parameters. This is a rare location for a schwannoma, and neurogenic tumor should be included in the differential diagnosis of soft-tissue mass, as there have been prior case reports.
Reported here is the case of a 55-year-old woman presenting to a podiatry clinic with a chief complaint of left heel and ankle pain, who ultimately underwent operative excision of an angioleiomyoma adjacent to the tibialis posterior artery at the level of the medial malleolus. Accompanying this case are images from three modalities through which the defining characteristics of an angioleiomyoma can be appreciated. This case advocates for the inclusion of angioleiomyoma in the preoperative differential diagnosis of a mass presenting as a pseudoaneurysm in the lower extremity, particularly among women in the fourth to sixth decades of life.
Osteochondromas are benign osseous tumors encountered most routinely by physicians responsible for diagnosing musculoskeletal disorders. Often, these osseous lesions are identified following symptoms related to their impingement on adjacent soft tissue or bone.
This article presents a unique case of an asymptomatic osteochondroma of the distal fibula in a 29-year-old Caucasian woman that manifested clinically as an impingement on the tibial nerve.
After resection of the osteochondroma, the patient's tarsal tunnel syndrome symptoms resolved.
This case report demonstrates a never-before-described osteochondroma of the distal fibula traversing posterior to the ankle joint and impinging on the tibial nerve. After resection, the patient's symptoms resolved.
