Psoriasis is an erythematous scaly dermatosis with clinical polymorphism; its pathophysiology results from the shortening of the epidermal cell cycle associated with genetic and environmental factors. It occurs in 2% of the world population; the most common form (in 80% of cases) is psoriasis vulgar. Inverse psoriasis has been reported in 24%, observed in folds (armpits, genitals, intergluteal, retroauricular, and inframammary regions). The case of a 76-year-old female patient with skin phototype IV/VI according to Fitzpatrick is presented, with a generalized, bilateral and symmetrical dermatosis predominantly affecting intertriginous areas (submammary, groin, armpits, and intergluteal area), in addition to the scalp and thorax, characterized by erythematous plaques with well-defined, regular borders, with involvement of the inframammary fold measuring 30 × 15 cm, some with adherent, pruritic scales of eight years' duration. KOH examination reported Candidiasis, with a culture positive for C. albicans. Histopathology confirmed psoriasis vulgaris. Treatment with methotrexate 15mg, fluconazole 150 mg, corticosteroids, and antihistamine was indicated.
