title: Unusual presentation of mycosis fungoides as pigmented purpura with malignant thymoma.
abstract: Thymoma is known to be associated with many lymphoreticular and nonlymphoreticular tumors. A woman who presented with patch stage mycosis fungoides with skin lesions resembling a pigmented purpura was found to have an anterior mediastinal mass on routine staging evaluation. A core needle biopsy of the mass revealed a lymphocyte predominant malignant thymoma. Review of the literature reveals many diseases with dermatologic manifestations associated with thymoma; however, malignant thymoma coexisting with mycosis fungoides has not previously been reported.
