B35-B49: Mycoses

B43: Chromomycosis and phaeomycotic abscess

Chromomycosis and phaeomycotic abscess are types of fungal infections, usually caused by fungi present in the environment, particularly in soil and decaying wood. These conditions can be transmitted through a break in the skin, typically after injury. Both conditions primarily affect the skin and subcutaneous tissues, often in the legs. Initial symptoms may include small, itchy, and warty skin lesions that are often mistaken for insect bites. Over time, these lesions can enlarge and become nodular, leading to complications like secondary bacterial infections or abscess formation. Abscesses are painful, swollen areas filled with pus. Progression of the disease can be slow, taking several months to years, which sometimes leads to delays in diagnosis.
