Acquired constriction ring syndrome is a clinical condition of infancy characterized by circumferential constriction of a toe or another appendage, such as fingers and genitalia. The foot and ankle specialist should be aware of this condition because vascular obstruction of the affected appendage can rapidly lead to gangrene and autoamputation. Treatment consists of prompt identification and removal of the constricting foreign material. Although this condition is uncommon, it can lead to digital loss. Early treatment yields a good prognosis. A case report is presented of a 9-week-old infant who experienced acquired constriction ring syndrome caused by a strand of hair wrapped around the third and fourth toes that was treated by unwinding the hair under loupe magnification.

In this study, we present the management of an intra-articular fracture in a 13-year-old boy with WAGR syndrome, an extremely rare genetic disorder. The goal of this study was to provide possible solutions to the complex pain management requirements presenting in the setting of trauma to the right lower extremity. Given the scarcity of literature available with regard to this condition, we aim to not only increase awareness of the disease but also provide insight into trauma management and expected outcomes.
This article reports on a 45-year-old woman who presented with pruritus and was diagnosed as having chigger mite infestation, a rare condition. The chigger mite larvae were encountered while the patient was traveling in South America. A small erythematous area with a well-circumscribed papule in the sulcus of the second digit of the right foot was incised and drained. Follow-up examination showed relief of all symptoms, including pain and pruritus. This unusual case presentation underscores the need for all podiatric physicians to obtain a comprehensive history, including history of travel, along with performing a thorough physical examination.

Achilles tenotomy is performed for the residual equinus deformity in the Ponseti method of clubfoot treatment. In the present article, we describe a mini-open Achilles tenotomy technique to prevent complications that could occur during tenotomy. This technique was performed on 15 patients (25 feet) during a 3-year period in our clinic on patients whose equinus deformities could not have been corrected by manipulations. Clear improvement (mean angle, 30°) was observed in equinus in our patients, and we have not seen any complication in this method. We conclude that direct visualizing of the tendon with mini-open incision may reduce the risk of neurovascular injury, especially for surgeons who are not experienced.

In this article, we present a 25-year-old man who developed an asymptomatic schwannoma on his left lateral heel and review the salient features of this cutaneous condition. A schwannoma is a slowly growing neoplasm of Schwann cell origin. Histology shows high cellularity (Antoni A regions), nuclear palisades (Verocay bodies), and alternating myxoid regions (Antoni B regions). Very few cases have been reported on the foot or ankle. As with this patient, most schwannomas do not cause symptoms, but some result in dysesthesia and nerve dysfunction. Multiple schwannomas may indicate an underlying syndrome such as neurofibromatosis type 1, type 2, and schwannomatosis. The differential diagnosis for schwannoma includes fibrosarcoma, leiomyosarcoma, and neurofibroma. The definitive treatment is surgical excision. This usually results in complete resolution with minimal recurrence, as was the case for this patient.
Melorheostosis is a nonhereditary and uncommon condition that can affect both adults and children. It can appear on radiographs as increased sclerosis on bones of the upper and lower extremities and may mimic other bony conditions such as osteopoikilosis, osteopetrosis, arthrogryposis multiplex congenita, and osteopathia striata. The sclerotic appearance can differ greatly between adults and children. The skin and subcutaneous tissues may be affected by fibrosis, resulting in contractures of joints and limbs that lead to deformities and limb-length discrepancies. This article reviews the literature on melorheostosis and describes a case in a 10-year-old boy. (J Am Podiatr Med Assoc 95(2): 167–170, 2005)
Macrodystrophia lipomatosa is a rare disorder characterized by three-dimensional enlargement of one or more fingers or toes with predominantly fibroadipose tissue. Radiographically, it appears as hypertrophy of soft tissues and bones. The pathologic findings are infiltration and hypertrophy of adipose tissue in subcutaneous tissue, nerve sheaths, and periosteum. Macrodystrophia lipomatosa is usually diagnosed during childhood. The case presented here involves the most elderly patient with the condition ever reported, to our knowledge. As such, it may advance current knowledge of macrodystrophia lipomatosa. Special emphasis is given to the unique “bridge” formation seen radiographically in this case. (J Am Podiatr Med Assoc 95(5): 486–490, 2005)
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.
Acute rheumatic fever is a delayed inflammatory disease that follows streptococcal infection of the throat. Poststreptococcal reactive arthritis is a sterile arthritis associated with antecedent streptococcal infection in patients not fulfilling the Jones criteria for acute rheumatic fever. Poststreptococcal reactive arthritis has been reported to have lower-extremity predominance and, therefore, should be included in the differential diagnosis of patients with lower-extremity arthritis. A review of the literature, distinguishing poststreptococcal reactive arthritis from acute rheumatic fever, and treatment options are discussed here. A case report is also presented.
