Cutaneous lymphoid hyperplasia (CLH) is a benign, reactive proliferation of B or T cells resulting in lesions clinically and histopathologically mimicking cutaneous lymphomas. Clinically, the lesions are nodules or plaques, clinically indistinguishable from cutaneous B-cell lymphomas, mycosis fungoides (MF), and other malignancies. Common triggers of CLH are skin infections, drugs, contact allergens and irritants.

摘要

Cutaneous lymphoid hyperplasia (CLH) is a benign, reactive proliferation of B or T cells resulting in lesions clinically and histopathologically mimicking cutaneous lymphomas. Clinically, the lesions are nodules or plaques, clinically indistinguishable from cutaneous B-cell lymphomas, mycosis fungoides (MF), and other malignancies. Common triggers of CLH are skin infections, drugs, contact allergens and irritants.
