Development of two different histologic types of lymphoma in the same person is rare. Sequential lymphoma is defined as two different types of lymphoma occurring sequentially in the same person. In particular, sequential Hodgkin’s lymphoma (HL) following non-Hodgkin’s lymphoma (NHL) is extremely rare. A 63-year-old female diagnosed with B-cell NHL at the mass in T3 received treatment with an R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone) protocol for six cycles. However, 12 months later, the patient complained of a left neck mass and excisional biopsy was performed. Microscopically the biopsied tissue showed Reed-Stemberg cells and confirmed the diagnosis of HL. The patient was treated with ABVD (adriamycin, bleomycin, vinblastine and dacarbazine) for four cycles. Although the possibility of a secondary malignancy cannot be excluded, this is a rare case of sequential Hodgkin’s lymphoma following Non-Hodgkin’s lymphoma.
