HTLV-1 is a virus linked to various diseases, but many associated conditions remain poorly understood, leading to challenges in diagnosis.
Skin issues like infectious dermatitis are common in HTLV-1 patients, but other manifestations, such as erythema nodosum (EN), may also occur.
A new case highlights the need to consider HTLV-1 in diagnosing EN, particularly in areas where the virus is prevalent, especially since the patient had been asymptomatic for a long time.
