The peritoneal mesothelioma is a rare pathology with unspecific symptoms reason to be a difficult diagnosis. We report a case of a 58 year old man with diabetes mellitus type 2, arterial hypertension and smoking; without precedent of asbestos exposure. The patient presented a one month history characterized by progressive increase of the abdominal volume and sensation of fullness; three weeks later they added breathlessness and hyporexia. The patient was in regular general condition; he was not presenting hepatic stigmas, edema or adenomegalies. The examination of thorax and cardiovascular it was normal. The abdomen distended by ascites, not painful, liver and spleen not examined. Laboratory: Hemoglobin 11,9 gr/dl, WBC 6840/mm3 Bands 1 %, lymphocytes 10 %, platelets 620000/mm3, PT 12 seconds, PTT 34 seconds, glucose 158 mg/dl, BUN 20,5 mg/ dl, creatinine 1,2 mg/dl, proteins 6,1 gr/dl, albumin 2,6 gr/dl. LDH 316 U/l, beta2microglobulin 2,2 mg/l (0.83-1.15 mg/l). HBV and HCV negative. Ca 19.9, CEA, AFP and PSA negative. Hemocultive negative. Ascitic fluid: ADA 20,3 U/l, serum-ascitic albumin gradient (SAAG) 1,1. Leukocytes 2237 cells/mm3, PMN 6 %, lymphocytes 90 %, mesothelial cells 4 %, proteins 4,6 gr/dl, albumin 2,34 gr/dl, glucose 44 mg/dl, LDH 1918 U/l. Gram and cultive: negatives. BAAR and cultive: negative . Cytology: mesothelial cells with changes of type reagent, Block cell for tumour cells: negative. Abdominal US: increased peritoneum and abundant ascitic fluid. Thoracic-abdominal CT: left side pleural effusion, severe ascites with thick epyplon. Upper GI endoscopy: moderate gastritis. Colonoscopy: two small sessile polyps in sigmoid colon. The finds of the laparoscopy were interpreted like carcinomatosis or peritoneal tuberculosis. The report of the peritoneal biopsy was informed as suggestive of undifferentiated carcinoma; the reappraisal with inmunohystochemic (calretinin +,cytokeratin +, vimentin +) indicated malignant peritoneal mesothelioma, type epithelial. The evolution was torpid. The patient was transferred to the Service of Oncology where they initiated chemotherapy with Cysplatin (CDDP) and died 20 days later. The malignant mesothelioma peritoneal is a unfrequent entity, with limited therapeutic options; generally detected late, with a palliative treatment.

A 6-year-old, male castrated, mixed-breed dog was referred to the James L. Voss Veterinary Teaching Hospital at Colorado State University for bicavitary effusion. On examination, the dog was tachycardic and tachypneic with bilaterally decreased lung sounds. Thoracic and abdominal ultrasonic examination revealed pleural and peritoneal effusions, which were aspirated and submitted for fluid analysis and cytology. Both cavity fluids were classified as exudates with a large population of vacuolated mononuclear cells. Multiplex immunocytochemistry (ICC) for cytokeratin and vimentin demonstrated exclusively cytokeratin expression, indicating these cells were of epithelial origin. A full diagnostic evaluation was performed, including CBC, clinical chemistry, a pet-side test for heartworm disease, ehrlichiosis, Lyme disease, and anaplasmosis, imaging modalities of thorax, abdomen, and heart, urinalysis, and fine-needle aspirations of spleen, liver, and popliteal lymph nodes. The dog was diagnosed with pleural and peritoneal carcinoma with presumed carcinomatosis. A single dose of intracavitary carboplatin was administered before discharge, and over a period of 2 weeks, 5 thoracocenteses were performed. A subcutaneous mass was noted at a thoracocentesis site one week after initial presentation. Cytology of the mass was consistent with carcinoma, and neoplastic seeding of the tumor cells from the thoracocentesis was suspected. The dog was euthanized 15 days after the first visit, and a necropsy was performed. Findings were consistent with carcinomatosis secondary to anaplastic pulmonary carcinoma with transient subcutaneous seeding of neoplastic cells during routine thoracocentesis. This case demonstrates the utility of multiplex ICC in the clinical setting.
