Hydroa vacciniforme-like lymphoma

Hydroa vacciniforme-like lymphoma is a rare cutaneous T-cell lymphoma occurring in children associated with Epstein–Barr virus (EBV) infection. We reported a 15-year-old Chinese boy who presented with a 3-month history of recurrent special clinical manifestations including vesicles, erythematous papules, ulcer, crusting, and smallpox-like scar on his head, face, neck, limbs, and ankles. EBV-DNA level was positive. Immunohistochemistry showed CD2(+++), CD3(+++), CD4(+), CD5(++), CD7(+), CD8(±), CD56(+), ki67 (30%+), Gr-B(+++). The patient showed a significant improvement in clinical symptoms after being treated with interferon alpha and prednisone.
