Summary We present a patient with primary CD30+ cutaneous T-cell lymphoma whose histological and clinical features overlapped with those of granulomatous slack skin disease (GSSD). A 26-year-old woman had infiltrative erythema on the abdominal wall and an incurable ulcerative lesion on the left knee. Her skin progressively became atrophic and pendulous, showing a hyperpigmented appearance over almost the whole body. Histopathologically, a dense lymphoid cell infiltrate accompanying numerous macrophages and multinucleated giant cells (MGC) extended into the subcutaneous tissue. Most lymphoid cells were small and positive for T-cell markers. Some relatively large atypical cells were scattered in the lesion, most of which (60%) were positive for CD30. T-cell receptor-β gene rearrangement was confirmed in the abdominal lesion. MGC infiltrated more dominantly into a deeeper layer of the skin with the elastic fibres there almost completely disappearing. Immunoreactivity for CD30 of MGC was negative and overexpression of elastolytic metalloproteinases was observed. The association between primary cutaneous CD30+ lym- phoproliferative disorders and GSSD has not previously been reported. Overexpression of elastolytic metalloproteinases in MGC contributes to the disappearance of the elastic fibres and enhances the severity of the clinical course.
