Abstract
ABSTRACT.
Erythema nodosum (EN) is characterized by rapidly developing, painful, erythematous subcutaneous nodules, most of which are located in the pretibial areas. This cutaneous finding can be caused by a variety of conditions, however Burkholderia pseudomallei is rarely the cause. This particular patient presented with a high-grade fever with characteristic EN on both pretibial areas. All of the typical EN causes were investigated, but the findings were all negative. The lesions progressed to severe hemorrhagic bleb features, and because the patient resided in Northeast Thailand, a melioidosis-endemic region, testing for B. pseudomallei was performed. Because a high level of melioidosis serology of more than 1:10,240 was detected, melioidosis therapy was started. At the 12-week follow-up after melioidosis therapy, the titer had declined to 1:1,280, indicating that melioidosis-related severe, cutaneous EN symptoms were the most likely diagnosis in this patient. We discovered a case of EN with severe hemorrhagic bleb features as a unique clinical manifestation of melioidosis. When a patient resides in an endemic area, B. pseudomallei should always be considered as a possible causative organism.
