RESUMO
Focal epithelial hyperplasia is a rare, benign, and asymptomatic disorder, characterized by soft papules on the oral cavity. It is primarily associated with human papillomavirus genotypes 13 and 32. It most commonly affects children and young adults. When it affects young adults, it is important to differentiate it from oral condyloma acuminata. Its diagnosis may be made clinically, but histologic examination and PCR genotyping are often useful. Treatment is not always mandatory.

Tanto la pitiriasis liquenoide y varioliforme aguda como la pitiriasis liquenoide crónica representan 2 extremos de un espectro de enfermedad de etiología desconocida. En este trabajo se describen 2 casos de pitiriasis liquenoide y varioliforme aguda, en los que se detectó ADN de virus herpes humano tipo 7 en muestras de piel mediante la metodología de reacción en cadena de la polimerasa, una asociación no descrita previamente. Este manuscrito puede apoyar la participación de la infección viral en la etiopatogenia de esta enfermedad
Pityriasis lichenoides et varioliformis acuta and pityriasis lichenoides chronica represent 2 ends of a disease spectrum of unknown etiology. Herein we describe 2 cases of pityriasis lichenoides et varioliformis acuta, in which human herpesvirus 7 DNA was detected in skin samples by polymerase chain reaction methodology, an association not previously described. This report may support the involvement of viral infection in the etiopathogeny of this disease
