ABSTRACT
El exantema laterotorácico unilateral de la infancia (ULE) es una condición benigna, de etiología desconocida, que se caracteriza por un exantema maculopapular que típicamente afecta, de forma unilateral, un pliegue axilar con posterior diseminación centrífuga. Paciente de 19 años, sin antecedentes mórbidos que presentó una erupción cutánea pruriginosa de inicio en la axila derecha con posterior diseminación a la axila contralateral y pliegues inguinales. Acude con exámenes de laboratorios en los que destaca serología positiva para Mycoplasma pneumoniae. El exantema laterotorácico unilateral de la infancia es una erupción benigna de presentación característica en niños pero que también se puede presentar en adultos. Su etiología es desconocida, pero su presentación en relación a fiebre, síntomas infecciosos respiratorios y gastrointestinales antes o durante el exantema, sugieren un origen viral o bacteriano. En este caso, planteamos como posible agente etiológico a Mycoplasma pneumoniae.

Rat-bite fever is an uncommon disease known for its endemicity to occur worldwide. Although most patients tend to develop mild symptoms with improvement from conventional antibiotics, it can progress with severe complications with a mortality rate as high as 13% without proper treatment. The authors report a complicated case of rat bite-fever involving a 61-year old woman who presented with fever petechial rash, and septic arthritis following a rat bite. Initially, multiple antibiotics were administered but were not effective. As a consequence, invasive procedures such as arthrotomy and joint debridement were done and prolonged antibiotic was administered until clinical resolution. Since many cases do not have a history of rat bite and may present with fever, rashes, and arthritis it is essential to distinguish it from other diseases. Here, the authors will provide details on the etiology, clinical manifestations, diagnosis, and management to aid prompt detection and treatment of the disease.
