title: [CD8-positive, CD30-negative cutaneous T-cell lymphoma simulating pyoderma gangrenosum].
abstract: Ulcerated primary cutaneous lymphomas are not rare, but the clinical manifestation as a pyoderma gangrenosum look-alike is extraordinary. CD8-positive lymphomas are rare, unclassifiable tumours with variable prognosis. We report on a 49-year-old patient with a large ulcerated primary cutaneous lymphoma on the left chest wall presenting as pyoderma gangrenosum. With immunohistochemical staining, most lymphocytes were shown to be CD8-positive. The CD30 antigen was not expressed. After radiotherapy with complete skin irradiation, the lymphoma regressed completely. The patient has been free of relapse for 28 months so far.
