title: Cutaneous mycotic infections with pseudolymphomatous infiltrates.
abstract: We report on 3 patients with cutaneous mycotic infections (superficial dermatophytosis, 1 patient; trichophytia, 2 patients), who on histological examination revealed dense, superficial, and deep lymphoid infiltrates admixed with variable numbers of eosinophils and with large, atypical-looking, partly CD30-positive lymphocytes. All 3 patients had received steroid therapy (locally and/or orally) upon a clinical misdiagnosis of granuloma annulare. This unusual histopathologic presentation of cutaneous mycotic infections may be mistaken for a lymphoproliferative disorder, particularly for lymphomatoid papulosis.
