title: Eosinophilic pustular folliculitis starting initially only with palmoplantar pustular lesions. Report of a case and review of the literature.
abstract: We report a 23-year-old Japanese male with eosinophilic pustular folliculitis (EPF) that had started with palmoplantar rash. Only when follicular pustules appeared on the bilateral cheek 31 months later, we revised our initial diagnosis of pustulosis palmaris et plantaris (PPP) to EPF, and all the skin eruptions cleared mostly with indomethacin. A review of the Japanese literature for the past 20 years disclosed that in 207 cases of EPF so far reported, palmoplantar pustular lesion was noted in 38 (18%). Among them, in 16 cases (8%) the skin lesions started first from the palmoplantar region with the average period of 26 months until the appearance of other eruptions of EPF. None of them was diagnosed as EPF when skin lesions were localized only to the palmoplantar region. When we find pustules on the palmoplantar region, we should suspect the possibility of early lesions of EPF as well as PPP. Histopathologic demonstration of multilocular pustules located in the upper epidermis containing numerous eosinophils in the palmoplantar pustular lesions, together with the dramatic therapeutic response to indomethacin greatly favor the diagnosis of EPF.
