Sclerosing lymphangitis of the penis.

Nonvenereal sclerosing lymphangitis is a rare penile lesion consisting of a minimally tender, indurated cord involving the coronal sulcus and occasionally adjacent distal penile skin. This disorder most often occurs after vigorous sexual activity and resolves spontaneously. However, as evidenced by 2 of the 3 cases reported, this condition also may be associated with underlying sexually transmitted disease that necessitates specific therapy.

Persistent atypical lymphocytic hyperplasia following tick bite in a child: report of a case and review of the literature.

We report a 6-year-old girl who developed a red papule on the posterior neck at the site of a previous tick bite. Initial biopsy was performed a year after the bite and the specimen showed a dense lymphoid infiltrate with admixed CD30+ cells. The patient was referred to our center because of concern about the development of a CD30+ lymphoproliferative disorder.

Pedal interdigital condylomata lata: a rare sign of secondary syphilis.

Background: Condylomata lata of the toe webs are uncommon manifestations of secondary syphilis. Considering the recent decline in the incidence of syphilis in the United States, such lesions are likely to present infrequently. In some cases, this phenomenon may be the only physical sign of syphilis; therefore, it is important that a high index of suspicion is maintained when evaluating toe web lesions in patients at epidemiologic risk for syphilis.
