Endometrium was collected from 20 high-dose progestogen-treated patients and examined for leukocyte populations by immunohistochemistry and phloxine-tartrazine staining. A labelled streptavidin-biotin-alkaline phosphatase technique was used with antibodies against leukocyte common antigen (LCA), T cells (CD3), neutrophils (NP57), macrophages] (CD68, KP1) and B cells (CD20). The numbers of LCA (1070 +/- 117/mm2), CD3 (459 +/- 60/mm2), CD68 (129 +/- 21/mm2) positive cells and endometrial granulated lymphocytes (EGL) (236 +/- 41/mm2) were significantly higher than those in the control group (P < 0.001). Of these, EGL increased most (6.7 times). NP57 positive (NP57+) neutrophils were present in five out of 20 progestogen-treated samples and NP57 negative (NP57-) neutrophils in another six out of 20; while a neutrophil was only identified in one control tissue (P = 0.002). Three progestogen-exposed endometrial samples had either focal or extensive necrosis, and many NP57+ and NP57- neutrophils were present in the necrotic areas. EGL, neutrophils and macrophages are known to release a number of cytolytic and cell toxic molecules which may play a role in the initiation or acceleration of progestational endometrial necrosis.

Non-Hodgkin's lymphomas presenting exclusively in the liver are rather uncommon in adults and extremely rare in children. We describe a six-year-old white boy with jaundice, abdominal pain, and weight loss of two weeks duration. Physical examination disclosed asthenia, jaundice, abdominal swelling, large hepatomegaly, and ascitis. Aminotransferases bilirubin, and alkaline phosphatase were significantly elevated. Bone marrow aspiration, cerebrospinal fluid, chest x-ray, renal function tests, and uric acid were normal. Abdominal ultrasound showed liver enlargement with irregular regular borders, many parenchymal nodules in both liver lobes, a large hypoechogenic mass in the inferior segment of the liver, normal biliary ducts and two pancreatic nodules resembling those in the liver. Liver needle biopsy disclosed diffuse lymphomatous infiltration. Blast cells were positive for leukocyte common antigen (CD 45). Immunohistochemistry study for T or B cell lineage differentiation was not done. The child showed an excellent response to chemotherapy based on the BFM-83 protocol for B cell non-Hodgkin's lymphomas. The patient had his therapy discontinued in June 1995 and remains in first complete remission as of May 20th, 1996.
