Rare Case of Double-Positive CD4/CD8 Immunophenotype in Lennert Lymphoma With Cutaneous Involvement: A Case Report

We report a case of a 54-year-old woman presenting with fever, chills, general weakness, and a skin rash of erythematous patches on the trunk, extremities, and buttocks. A skin biopsy of the buttocks revealed atypical lymphocytes around the dermal vessels. In immunohistochemistry, these atypical lymphocytes stained positive for CD3, CD4, CD8, and CD68 but negative for CD20, CD30, and granzyme B. Similarly, a biopsy of the axillary LN revealed numerous epithelioid cells with atypical lymphocytes, exhibiting positivity for CD3, CD4, CD8, and CD68 but negativity for CD20, CD30, and S-100. Ki-67 was overexpressed in both the skin and LN. The final diagnosis of the patient was Lennert lymphoma with cutaneous involvement and a rare double-positive CD4/CD8 immunophenotype. The patient was transferred to another hospital for chemotherapy as per her request.
