Skin CD30+ lymphomas include a broad range of pathologies, such as lymphomatoid papulosis (LyP) and Anaplastic Large Cell Lymphoma (ALCL). The CD30 positive reaction is simply due to the lymphocyte activation and it may be related to benign skin eruption or in mycosis fungoides: such a positive reaction is not sufficient to make a diagnosis of lymphoproliferative syndrome. ALCL is a highly malignant skin lymphoma, present at any age, it may arise as primary skin lesion (more frequent in adult with better prognosis) or as a systemic form (more frequent in children and with a more severe prognosis). The skin lesions are represented by few nodular lesions developing as ulcers, with histology showing dermal and ipodermal infiltrates, mainly made of large lymphocytes with nuclear atypia and frequent mitoses. Two cases are described: a 56-year old male and a 25 year-old female; for both patients the diagnosis was reached after repeated admissions and histological examinations in different hospitals. After repeated chemotherapy and radiotherapy treatments, the male died due to the high malignancy of the lymphoma which was systematically diffused (liver, lungs).
