Abstract

INTRODUCTION: CD30+ anaplastic large T cell lymphoma is a cutaneous primary lymphoma in which there is no evidence of systemic disease; histopathological study is required for its diagnosis. OBJECTIVE: To present the cases diagnosed with primary cutaneous CD30+ anaplastic large T-cell lymphoma over a 24-year period in Hospital General "Dr. Manuel Gea González" Department of Dermatology. METHOD: Retrospective study. Descriptive statistics was carried out. Information was collected on gender, age, clinical characteristics, complementary test results, previous and current treatments, histopathological studies reports and immunohistochemistry test results. RESULTS: Of 29 309 records, nine patients (0.000034%) with a diagnosis of CD30+ anaplastic T cell lymphoma were found. Histopathological and immunohistochemical diagnosis was confirmed by two certified dermatopathologists. Average age was 61.2 years, and there was a predominance of the female gender, with initial clinical presentation as a papular or nodular lesion and varied topography. CONCLUSIONS: The prognosis of CD30+ anaplastic large T cell lymphoma in the studied population was dependent on clinical stage. The treatment at early stages has favorable results.
