Cutaneous protothecosis is a rare infection caused by achlorophyllic algae of the
genus Prototheca. The lesions usually occur on exposed areas, related with trauma, in
immunocompromised patients. The most common clinical presentation is a vesicobullous
and ulcerative lesion with pustules and scabs, simulating bacterial, fungal or
herpetic infections or eczema. The diagnosis is determined by agent identification
through histopathology, culture and the carbohydrates assimilation test. The finding
of morula-like spherules is characteristic of Prototheca sp. Its
rarity and non-specific clinical aspect may difficult the disease diagnosis. We
report a case of a diabetic patient, in chronic use of systemic corticosteroids, that
developed a skin lesion after trauma to the right leg.
The authors report a case of SAPHO Syndrome, in pediatric age, with a dermatological focus. This entity should be considered in patients who have pain in the anterior chest wall or other musculoskeletal symptoms, accompanied by palmoplantar pustulosis and acne fulminans. The specific cutaneous manifestations, diagnosis and the treatment will be presented.
