ABSTRACT
El Eritema Multiforme (EM) es una reacción cutánea aguda generalmente benigna y autolimitada, asociada a la infección por Virus Herpes Simplex (HSV). Se caracteriza por lesiones polimorfas y tipo diana en extremidades y mucosas. Presentamos un paciente de 22 años con pápulas, vesículas y ampollas, que evoluciona con un 90% de la superficie corporal comprometida en tres semanas. Se realizó una reacción de polimerasa en cadena para HSV, resultando positiva en una costra. La biopsia de piel y la tinción de inmunohistoquímica positiva para linfocitos T CD4, fueron compatibles con EM ampollar asociado a HSV. Destacamos la importancia de la correlación clínico patológica, apoyada por el estudio virológico, en el diagnóstico de este caso de presentación atípica. Los hallazgos de laboratorio confirmaron lo descrito en la literatura respecto de la patogenia del EM asociado a HSV.
Erythema Multiforme (EM) is a generally benign and self-limited acute cutaneous reaction, associated with Herpes Simplex Virus (HSV) infection. It is characterized by polymorphic "target" lesions in extremities and mucosal tissues. We report a 22-year old patient with papules, vesicles and blisters, which evolved to cover 90% of the body in three weeks. We performed a PCR study for HSV, which was positive in a crust. A skin biopsy and positive immunohistochemical stain for LT CD4+ were compatible with bullous EM associated with HSV. We underline the importance of pathological clinical correlation, reinforced by a virological study, in the diagnosis of this case with atypical symptoms. The laboratory findings confirmed literature descriptions with respect to the pathogenicity of EM associated with HSV.
ABSTRACT
In adults, bullous erythema multiforme is most often caused by herpes simplex virus infection, while Stevens-Johnson syndrome is most often associated with drug hypersensitivity. Mycoplasma pneumoniae infection is highly known to be a cause of bullous erythema multiforme and Stevens-Johnson syndrome in children and young adults. To our knowledge, there are only a few reports of bullous erythema multiforme or Stevens-Johnson syndrome induced by M. pneumoniae infection in the Korean literature. We encountered two cases of female children diagnosed as having bullous erythema multiforme associated with M. pneumoniae infection. We also describe an unusual case of Stevens-Johnson syndrome associated with M. pneumoniae infection in a 65-year-old woman.
