18 Alveolar cell carcinoma mimicking metastases to the lung. What is this organ?What are the lesions most likely to be?Where might they come from?1) Lung 2) Pulmonary metastases 3) Liver, Breast, G.I. tract, kidney.Adult male presented with severe dyspnoea and haemoptysis. CXR revealed multiple rounded opacities in both lungs and a diagnosis of pulmonary metastases from a primary of uncertain origin was made. The patient died shortly after admission.Autopsy confirmed the presence of multiple lung tumour, but a careful search failed to reveal any obvious primary source.Histology showed the tumour to be adenocarcinoma and a final diagnosis of alveolar cell carcinoma. This is a rare lung tumour and is often confused with pulmonary metastases.Where may lung metastases arise from?

On examination he was wasted and dehydrated.Specimen:large solid granular tumour filling the oesophagusDiagnosis: Carcinoma of the OesophagusQuestions:How does the tumour spread and what complications may arise?In which area of East Africa is this area commonly seen.
22 Carcinoma of the stomach H 151: AClinical:An adult male presented with hepatomegaly and was grossly wasted.Specimen:A large raised carcinomatous ulcer of the upper end of the lesser curve o the stomach.Diagnosis: Carcinoma of stomach (Ulcerating type).Questions:What are the local effects of the tumour?Which part of the world has a high incidence of this tumour?
23 Carcinoma of the caecum H 153: BClinical:A male patient presented with gross wasting and anemia (Hemoglobin 5 g/ml)Specimen:An irregular, rough polypoidal tumour of the caecum.Diagnosis: Carcinoma of the caecumQuestion: What is the mechanism of the anemia in this case?

Laparotomy done.Specimen:A solid white tumour at the apex of the intussusceptum has caused the intussusception.Diagnosis: Malignant lymphoma: intussusceptions.Question:What other lesions in the small intestine may lead to intussusceptions?
25 Carcinoma of the Rectum H154: BClinical:A male 60 years old, constipation, blood per rectum, loss of weight.Specimen:An annular, ulcerated carcinoma, with dilatation of the rectum above the tumour.Diagnosis:Carcinoma of the lower rectum.Question:What other tumors may occur in this region?
26 Cirrhosis of the Liver. H 581: A Clinical: A 28 year old Muganda male. On admission, he had gross ascites. Enlarged spleen and was mentally confused.Specimen:A small liver with pale nodules of hepatic parenchymal tissue, surrounded by darker fibrous tissue.Diagnosis: Cirrhosis of liver.Question:What results may be expected on laboratory examination of this patient’s ascetic fluid and serum?
27 Hepatocellular Carcinoma H 155: AClinical:A 37 year old Rwanda male. Pain and swelling in the right hypochondria for six weeks. He had haematemesis on the day of admission.Specimen:A cirrhotic liver with large nodules (macronodular).A solid tumour of the right lobe is spreading to involve the left lobe.Diagnosis:Hepatocellular carcinoma and cirrhosis:Question:Any views of carcinogenesis?
28 Diverticular disease of the small intestine. H 578: AClinical:An adult male had abdominal pain for some weeks before admission to the hospital.Specimen:Multiple diverticular on the mesenteric aspect of the small intestine. The upper specimen is congested and inflamed.Diagnosis:Diverticular disease of the small intestine.Questions:Is this disease common in Africans?What are the complications of the disease?What is known of the pathogenesis of the condition?
29 Mesenteric lymphatic cysts H 578: DClinical:A female patient 36 years old presented with acute abdominal paid and floating tumour in abdomen.Specimen:Large thin-walled cysts of mesentery, close to the intestine.Diagnosis:Mesenteric lymphatic cystsQuestion:These cysts may twist and produce acute pain.Could this have occurred in this patient?
30 Benign Chronic Gastric Ulcer H540: BClinical:A male Rwanda 40 years old had epigastric pain for some years. One morning he collapsed and was rushed to hospital. On examination: A pulse was rapid and thready, he was cold at the periphery of the blood and pressure was very low.Specimen:A large deep chronic ulcer high up on lesser curve of stomach. Eroded blood vessels in the base of the ulcer.Diagnosis:Benign chronic Gastric ulcer.Question:Why did he collapse?

36 Burkitts lymphoma-Immunohistochemistry. Ki67 The Ki-67is a cellular marker for proliferation.It is strictly associated with ell proliferation.During the interphase Ki-67 antigen can be exclusively detected within the nucleusin mitosis most of the protein is relocated to the surface of the chromosomes.Ki-67 protein is present during all active phases of the cell cycle (G1, S, G2, and mitosis), but is absent from resting cells (G0).Ki-67 is used as a marker to determine the growth fraction of a given cell population. Does the growth fraction affect the prognosis of the tumour? How?
