Erythema multiforme and herpes simplex virus.

It has been suggested that herpes simplex virus (HSV) can trigger erythema multiforme (EM) at different times. One recent study showed HSV antigen in immune complexes of patients with EM. The purpose of our study was to assess a possible association between EM and HSV. Sixteen patients and 16 matched controls were studied using an enzyme-linked immunosorbent assay (ELISA) to measure antibody of the IgG, IgA, and IgM classes against HSV-1. From our study on patients with oral erythema multiforme, we found no evidence to correlate the occurrence and/or severity of EM and the HSV-1.

Histopathologic spectrum of oral Kaposi's sarcoma.

There has been a striking increase in the incidence of oral Kaposi's sarcoma in association with acquired immunodeficiency syndrome (AIDS). Oral lesions are seen in approximately 50% of AIDS patients with Kaposi's sarcoma. Lesions may appear as a flat or raised pigmented area, often resembling a benign vascular lesion, and are commonly found on the palate. Useful histopathologic criteria for the recognition and diagnosis of oral Kaposi's sarcoma include (1) atypical vascular channels (especially in early lesions), (2) a prominent spindle cell component in later lesions, (3) extravasated red blood cells, (4) hemosiderin, (5) the presence of eosinophilic bodies, (6) chronic inflammatory cells in early lesions, and (7) mitotic figures in tumor-stage lesions.
