Angiocentric lymphomatoid granulomatosis and severe hypogammaglobulinaemia.

Angiocentric lymphomatoid granulomatosis is a rare lymphoproliferative disease, mainly associated with pulmonary manifestation. Its origin is unknown, but Epstein-Barr virus may be one of the etiological factors. A 51-year-old male had an abdominal laparotomy in 1994 and a large granulomatous mass was removed from behind the cecum. No specific therapy was administered. In February 1998 multiple pulmonary lesions were found by X-ray and thoracoscopic biopsy was made. The histopathological diagnosis was angiocentric lymphomatoid granulomatosis. The patient received 6 cycles of CHOP chemotherapy, with which a complete remission was achieved. A consistent severe hypogammaglobulinaemia was detected, so the diagnosis of common variable immunodeficiency (CVID) was established. The diagnosed CVID was the probable causative factor of the angiocentric lymphomatoid granulomatosis. After the CHOP treatment, the patient is on intravenous immunoglobulin substitution and is well up to today.
