ABSTRACT
Malignant schwannoma in the foot is extremely rare. The authors present a case involving the medial plantar branch of the posterior tibial nerve in a patient with neurofibromatosis, without previous history of malignant degeneration. Following full excisional biopsy, the diagnosis was made using immunohistochemical studies and electron microscopy. A review of the literature also is presented.

Malignant melanoma, the leading cause of death from disease of the skin, often is found on the lower extremity. A thorough understanding of the disease entity is essential, because misdiagnosis or delayed diagnosis can be fatal. In Part I of this two-part clinical and surgical review of malignant melanoma, the authors discussed etiology, risk factors, signs, symptoms, clinical features, and growth patterns. Part II places special emphasis on diagnosing malignant melanoma and differentiating it from other lesions of the lower extremity. Clinical staging of the tumor and the corresponding surgical criteria are presented from a podiatric medical standpoint.

Malignant melanoma, the leading cause of death from diseases of the skin, often is found on the lower extremity. When encountered by the podiatric physician, a thorough understanding of the disease entity is essential, as misdiagnosis or delayed diagnosis can have fatal consequences. The authors present the first of a two-part comprehensive clinical and surgical review of malignant melanoma. Part I reviews etiology, risk factors, signs, symptoms, clinical features, and growth patterns. In Part II, a pictorial lower extremity differential diagnosis will be provided, along with diagnostic and surgical criteria for the podiatric surgeon.

The etiology, diagnosis and surgical treatment of stenosing tenosynovitis of the peroneal tendons is presented. The authors stress the need for thorough understanding of this clinical entity as its symptomatology can mimic several more frequently encountered podiatric pathologies. This could result in delayed or missed diagnosis and, thus, improper management.
