Subungual exostosis is typically a benign, acquired tumor of cartilaginous bone occurring on the medial surface of the distal hallux. A 16-year-old boy with subungual exostosis of his left great toe is presented. We evaluated the English language literature on this topic from 1857 to 1994; including our patient, 312 cases have been described. The diagnostic characteristics (histologic and radiologic), etiologic features, and therapeutic management were reviewed. Subungual exostosis more commonly affects women than men in a ratio of 2:1. Most lesions occur in the early twenties; however, a minimum of 51 (16%) of the 312 cases of subungual exostoses appeared in children 18 years of age or younger. Seventy percent of lesions occurred on the first hallux. There was frequently an association with trauma. The diagnosis of subungual exostosis may be suspected from the clinical presentation and confirmed with radiographic examination. The treatment is surgical.

Hair follicle nevus: case report and review of the literature.

The study of hair follicle tumors can be confusing, and hair follicle nevi are no exception. Analogous lesions frequently have divergent appellations. We evaluated the English-language literature on hair follicle nevi and histologic equivalents from 1921 to 1994. In addition, we reviewed four standard dermatopathology textbooks for further examples. We found 20 published valid cases of hair follicle nevi. Two of the cases were called congenital vellus hamartoma. Hair follicle nevi are rare, benign, often congenital hamartomas composed of multiple vellus hairs. They are typically on the face. We present an infant girl with a hair follicle nevus and review the histologic features and nomenclature of the lesion.

Lymphangioma associated with Becker's nevus: a report of coincident hamartomas in a child.

Lymphangiomas are hamartomas which often occur during childhood. Their classification is primarily size dependent and predicts their clinical course. Larger lesions can be life threatening, but for many patients with lymphangiomas, cosmetic disfigurement is the primary concern. Treatment options are limited and have shown only variable success. Repetitive surgical excision may be necessary. We report a cystic lymphangioma of the axilla occurring in association with a Becker's nevus in an infant. Although Becker's nevi have been described in association with other hamartomas, primarily those of smooth muscle, an association with cystic lymphangioma has not been previously reported. We offer a brief discussion of possible developmental mechanisms for their coexistence. In our patient the simultaneous occurrence of a lymphangioma and a Becker's nevus appears to be a localized event, as no other developmental abnormalities are evident.

Reversible ischemic myelopathy during scoliosis surgery: a possible role for intravenous lidocaine.

An unusual and previously unreported case of partially reversible ischemic myelopathy after limited unilateral segmental vessel ligation during scoliosis surgery is described. Intravenous lidocaine, used intraoperatively for its vasoactive properties, induced an immediate and meaningful recovery of neurologic function. The conceptual and pharmacologic basis for this intervention is discussed in view of this exceedingly rare complication of segmental vessel ligation.
