Abstract
- Primary cutaneous CD30-positive, anaplastic large cell lymphoma (ALCL) is a rare cutaneous peripheral T cell lymphoma with a favorable prognosis. ALCL is characterized by a solitary or localized skin tumor composed of sheets of atypical lymphoid cells with pleomorphic or anaplastic nuclei. Herein we report a 67-year-old woman presented with tender nodules and severely pruritic numerous eruptive papules. Histopathologic examination revealed dense non-epidermotrophic infiltrates of atypical large cells with round, oval or irregularly shaped nuclei and abundant cytoplasm. Immunohistochemical studies demonstrated that most lymphoid cells in the dermis and subcutis were positive for CD30 and CD45RO, and negative for CD20 and CD56.
