Eosinophilic pustular folliculitis (EPF) is a cutaneous inflammatory follicular disorder of unknown etiology. The diagnosis is made on the basis of clinical and histopathologic features. We describe two patients who had recurrent episodes of pruritic follicular papular and pustular lesions on the face, extremities, and trunk. The eruptions lasted for 1 month with intermittent remissions. Laboratory tests disclosed no infectious or parasitic etiology in patient 2. In patient 1 we isolated methicillin-resistant Staphylococcus aureus in a blood culture. He had sepsis with lung and liver involvement. EPF is a self-limited dermatosis. On occasion, skin lesions may become superinfected, resulting in localized pyoderma or rarely systemic infection (sepsis). Histologically both of our patients showed a moderate mixed inflammatory infiltrate with numerous eosinophils centered around hair follicles. Their lesions responded well to topical corticosteroids.

A new type of organoid epidermal nevus, characterized by the presence of multiple trichilemmal cysts disposed in a linear arrangement, was recently recognized and named nevus trichilemmocysticus. We report a 10-year-old girl with a congenital linear dermatosis affecting the head, neck, trunk, limbs, palms, and soles. Initially, the lesions that followed the lines of Blaschko consisted of yellowish plaques covered by verrucous papules and filiform hyperkeratoses. Additionally, since the age of 6 years, numerous cyst-like structures developed on the linear lesions involving the limbs. On histopathological examination, all of the excised cystic lesions were found to be trichilemmal cysts. Hence, we herein describe a new case of nevus trichilemmocysticus.
