1/3. T-cell-rich B-cell lymphoma in a ring-tailed lemur (lemur catta).A 13-yr-old ring-tailed lemur (lemur catta) was evaluated for depression, anorexia, polyuria, and polydipsia. The lemur was in poor body condition and was anemic, hypoalbuminemic, and hyponatremic. Cytologic examination of aspirates of the spleen, liver, and bone marrow and histopathologic examination of liver and bone marrow biopsies revealed a disseminated round cell tumor. After euthanasia, necropsy revealed hepatomegaly, splenomegaly, and mesenteric lymphadenomegaly. Neoplastic cells were present within the spleen, liver, kidneys, multiple lymph nodes, bone marrow, lung, small intestine, pancreas, and testicle and were composed of large anaplastic round cells in a background of small well-differentiated lymphocytes. Immunohistochemical analysis revealed that the small well-differentiated lymphocytes labeled for the anti-human T-cell marker, CD3, and the large anaplastic round cells labeled with the anti-human B-cell marker, CD79a. On the basis of the immunohistochemical staining results and morphologic appearance, a diagnosis of a T-cell-rich B-cell lymphoma was made.- - - - - - - - - - ranking = 1keywords = spleen (Clic here for more details about this article) |
2/3. The technique of laparoscopic retroperitoneal splenopexy for symptomatic wandering spleen in childhood.BACKGROUND: wandering spleen is an uncommon diagnosis, difficult to prove by standard investigations. The authors report a new method for laparoscopic splenopexy in children using a balloon-dilated retroperitoneal pouch. methods: From 3 accesses, the spleen is mobilized and displaced into a retroperitoneal pouch dilated to the double splenic volume. The pouch is dilated by a self-made balloon via a further intercostal access and narrowed by sutures incorporating the cranial and caudal edge of the gastrosplenic ligament. RESULTS: The peritoneal pouch contracts around the retroperitoneal spleen resulting in a firm fixation of the organ. This technique was successful in a 9-year-old girl with a 5-year history of severe recurrent abdominal pain. CONCLUSIONS: Laparoscopic retroperitoneal pouch splenopexy is a safe and effective procedure for symptomatic wandering spleen precluding the use of foreign materials in this age group.- - - - - - - - - - ranking = 4keywords = spleen (Clic here for more details about this article) |
3/3. Clinicopathological conference: case report--a case of anorexia and weak arm.The authors present the case of a 49-year-old female who presented to the emergency department with a chief complaint of "not eating well." She was found to have a heart murmur, a focal neurological deficit, and large mitral valve vegetation. The patient was later diagnosed with acute Pseudomonal endocarditis with septic emboli to the brain, liver, spleen, and kidneys. A discussion of the patient presentation, diagnostic evaluation, and outcome are reviewed.- - - - - - - - - - ranking = 0.5keywords = spleen (Clic here for more details about this article) |
