  • Title: [Cyclic neutropenia complicated of non-Hodgkin lymphoma].
    Author: Arai N, Umeda M, Shirai T.

    Abstract:
    This paper reports a case of non-Hodgkin's lymphoma concurrent with cyclic neutropenia. A 59-year-old man who exhibited a neutropenia at a periodicity of 14-20 days from July 1986 was diagnosed as having cyclic neutropenia, and was re-admitted to our hospital because of an abdominal tumor in April 1988. Gastroscopy revealed a Borrmann II-like elevated lesion, and abdominal CT scanning showed a low density area in the liver and swelling of the para-aortic lymph nodes. According to histological examination of the stomach and the liver, the patient was diagnosed as having non-Hodgkin's lymphoma (diffuse, medium-cell type). After completion of three courses of COP-BLAM III therapy, which was started on June 7, a partial response was achieved. However, the patient had a relapse and died on May 12, 1989. Cyclic neutropenia in this case was not considered to be due to an immunological abnormality mediated by lymphocytes, but may have been caused by an excessive response of the negative feedback mechanism due to an increase in CIA (Colony-inhibiting activity) of neutrophils. The fact that the patient's EB virus antibody titer became higher than at this initial hospitalization suggests the possible transition from chronic EB virus infection into malignant lymphoma.
