[Hailey-Hailey disease with dissemination and eczema herpeticatum in therapy with etretinate].

We report a 39-year-old patient with Hailey-Hailey disease localized mainly in the genito-femoral and scrotal areas. During hospital treatment the condition worsened due to superinfection with Candida albicans and gram-negative bacteria. Treatment with systemic steroids followed by aromatic retinoids was tried: eczema herpeticum developed in the affected areas, and dissemination of Hailey-Hailey disease ultimately occurred with papulo-vesicular and histologically characteristic lesions.
