Background: The metastatic spread of feline lymphoma to the peritoneum ("lymphomatosis") has been rarely reported in the literature. The sonographic features specific to this rare disease manifestation have not been described and have important treatment and prognostic considerations prompting definitive diagnosis., Objectives: To describe the ultrasonic features of feline peritoneal lymphomatosis., Animals: Four cats with alimentary lymphoma and peritoneal metastasis confirmed using cytology, histology, or both., Results: The sonographic features described include either a nonobstructive, focally diffuse, and circumferential intestinal mass, or an eccentric, focally diffuse, gastric mass. The intestinal and gastric lesions exhibited hypo-to-anechoic transmural wall thickening with loss of wall layering in association with discrete-to-coalescing plaques or sheets of thickened, hypoechoic tissue throughout the mesentery or omenta. All cases exhibited only small volumes of anechoic free peritoneal fluid. Three of the 4 cats also had multiple small hypoechoic nodular foci on the parietal and/or visceral peritoneal surfaces. Two cats had bilateral renomegaly because of lymphoma invasion (2/4) and 1 cat had local lymphadenopathy secondary to lymphoma invasion (1/4)., Conclusions and Clinical Importance: Peritoneal lymphomatosis is a rare manifestation of lymphoma metastasis and to date appears to be associated specifically with B-cell alimentary lymphoma., (Copyright © 2018 The Authors.

This paper has especial interest for the laboratician and dairy inspector, and general interest to everyone. Mr. Laboratician, do you test for "number" or "kind?" Mr. Inspector, do you work in coöperation or in opposition to the laboratory? Doctor North is well suited to write on the milk question, and he discusses in a clear and convincing manner the many problems essential to the maintenance of the health standard of this industry. more...

Dr. North knows what he is writing about. No food industry is so much discussed as the production and marketing of milk. Everyone engaged in it places the responsibility somewhere else. Dr. North goes to the root of the matter with facts and figures, and shows lack of coöperation, coördination and organization. more...
