A 12-year-old Thoroughbred mare, with a history of anorexia, dramatic weight loss, fluctuating pyrexia and intermittent diarrhoea after an episode of colic, was presented for examination with depression, emaciation and ataxia. Thoracic and abdominal paracenteses yielded copious quantities of inflammatory exudate. Palpation per rectum revealed an enlarged spleen. The primary alterations in haematology included a severe leucocytosis with a left shift, and a hyperproteinaemia characterised by hypoalbuminaemia and hypergammaglobulinaemia. Post-mortem examination revealed a low grade pleurisy and peritonitis with fluid accumulation in both cavities. A suppurative gastritis with full thickness perforations of the stomach wall associated with Gasterophilus intestinalis larvae had extended to the juxtaposed organ initiating an extensive suppurative splenitis. Streptococcus zooepidemicus was cultured.

Splenic pseudocysts have traditionally required splenectomy because of the risks imposed by partial splenectomy or excision of the cyst lining. During the past 2 years, a 6-year-old boy and a 9-year-old girl presenting with vague upper abdominal discomfort, palpable splenomegaly, and a large unilocular sonolucent cyst within the spleen, were treated by partial splenic decapsulation with preservation of the hilar blood supply. This procedure involves mobilizing the spleen by dividing the renal, colic, and diaphragmatic attachments; decompressing the liquefied cyst contents through a thoracostomy trochar; excising the outer splenic capsule and gaining hemostasis of the splenic wall with a running interlocked silk suture; and providing external tube drainage of the left upper quadrant. During the follow-up period of 26 and 12 months, splenic size has returned to normal. Serial nuclear scan and ultrasound show a small residual crescent-shaped deformity of the functioning splenic remnant. We conclude that partial splenic decapsulation for splenic pseudocyst is simpler and safer than other preservation procedures attempted, and carries no increased risk of recurrence from leaving a portion of the pseudocyst wall.

On clinical examination, a six-year-old Hassian gray gelding with a history of impaired performance, slight cough, colic, and edema of the ventral abdomen, prepuce and the legs had reduced skin turgor, pale mucous membranes, forced costoabdominal breathing, reduced venous return, enlarged lymph nodes, and splenomegaly. Hematologic findings revealed anemia, leukocytosis and a high percentage of monocytoid leukemic cells. Generalized lymphadenopathy, splenomegaly, ascites, hydrothorax, and a diffusely thickened gut wall were found at necropsy. Massive infiltration with monocytoid leukemic cells was detected in lymph nodes, spleen, bone marrow, liver, gut wall, kidneys, and choroid plexus. Incubation of living cells obtained from a leukocyte concentrate with latex particles revealed phagocytosis in the leukemic cells on light and electron microscopy. The leukemic cells also had a marked alpha-naphthyl-acetate and naphthol-AS-acetate esterase activity, but were only weakly positive to naphthol-AS-D-chloroacetate esterase. A very weak alkaline phosphatase activity only was demonstrated in a few leukemic cells. On scanning electron microscopy, the leukemic cells had prominent ruffles and ridge-like profiles. These features of the leukemic cells excluded lymphocytic and granulocytic leukemia, and monocytic leukemia was diagnosed.

Fifty-three cases of infective endocarditis are reported: 10 definite, 33 probable, 10 possible. There were: 35 males, 18 females, mean age: 66 +/- 14 years. Twenty-three patients had a known valve involvement, 21 a recently diagnosed valve involvement, 9 a prosthetic valve. Fifty patients had fever, 43 had a regurgitating murmur, 28 weakness and weight-loss, 13 cutaneous lesions, 11 arthritis, 8 splenomegaly, 3 ocular lesions. The portal of entry was suspected or confirmed in 37 cases: intestinal in 12 cases, dental in 11 cases, cutaneous in 7 cases, urinary tract infection in 6 cases, upper respiratory tract infection in 1 case. The micro-organism was found in 45 cases: 10 oral streptococci, 12 D bovis streptococci, 6 enterococci, 5 aureus staphylococci, 3 coagulase-negative staphylococci, 2 Coxiella burnetii, 7 other bacterias. Blood-cultures were negative in 8 cases. Precordial echocardiography found vegetations in 27 native valves and 9 prosthetic alterations. Ten patients had neurologic complications, 27 cardiac complications, 8 acute renal failure. Nine patients needed cardiac surgery, 6 died. Our results, compared with those in the literature, showed older age, a higher frequency of digestive portal of entry and of D bovis streptococci, frequently associated with a colic tumour.

Tumors composed of discrete round cells with large eosinophilic granules in their cytoplasm were observed in four cats. These cats were presented with severe gastrointestinal signs, including anorexia, vomiting, and diarrhea. The exploratory laparotomy in two cats and necropsy in the other two revealed thickening and perforation of the intestinal walls, enlargement of the mesenteric, ileocolic, and/or colic lymph nodes, and splenomegaly. Histologically, there was severe and disseminated infiltration of the tumor cells in the affected organs. In the two cats necropsied, the spleen and the jejunal mucosa appeared to be the primary organs involved. The tumor cells of all the cats showed the pore-forming protein (perforin)-like immunoreactivity unique to the cytotoxic lymphocytes but failed to show histamine immunoreactivity. These results indicate that the tumor cells were derived from large granular lymphocytes and that perforinlike immunoreactivity may be a useful marker for histologic diagnosis of feline large granular lymphoma.

A 14-year-old Arabian cross-bred gelding was referred to the University Clinic because of mild, recurrent signs of colic for 5 days. The pony showed icteric mucous membranes, haemolytic blood, and dark coloured urine. Internal examination did not give a clear diagnosis. Unidentified intra-abdominal strands were found and haemorrhagic abdominocentesis led to the decision to perform an exploratory laparatomy. An extremely enlarged spleen was the sole finding. A splenal biopsy sample was taken and surgery was completed. The pony remained colicky, so the spleen was examined by ultrasonography. After this examination, the tentative diagnosis 'tumour of the spleen' was made and splenectomy was performed. Pathological examination of the spleen revealed splenomegaly caused by infarctions of unknown origin. Eight weeks after surgery, the pony started again in dressage competition. Six months after splenectomy, the pony won the provincial dressage competition.

We report a case of primary colonic lymphoma incidentally diagnosed in a patient presenting a gallbladder attack making particular attention on the diagnostic findings at ultrasound (US) and total body computed tomography (CT) exams that allowed us to make the correct final diagnosis. A 85-year-old Caucasian male patient was referred to our department due to acute pain at the upper right quadrant, spreaded to the right shoulder blade. Patient had nausea and mild fever and Murphy's maneuver was positive. At physical examination a large bulky mass was found in the right flank. Patient underwent to US exam that detected a big stone in the lumen of the gallbladder and in correspondence of the palpable mass, an extended concentric thickening of the colic wall. CT scan was performed and confirmed a widespread and concentric thickening of the wall of the ascending colon and cecum. In addition, revealed signs of microperforation of the colic wall. Numerous large lymphadenopathies were found in the abdominal, pelvic and thoracic cavity and there was a condition of splenomegaly, with some ischemic outcomes in the context of the spleen. No metastasis in the parenchimatous organs were found. These imaging findings suggest us the diagnosis of lymphoma. Patient underwent to surgery, and right hemicolectomy and cholecystectomy was performed. Histological examination confirmed our diagnosis, revealing a diffuse large B-cell lymphoma. The patient underwent to Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisone chemotherapy showing only a partial regression of the lymphadenopathies, being in advanced stage at the time of diagnosis.
