A 40 year old female presents with mediastinal hilar lymphadenopathy and she has recently noticed slight weight loss and a cough. Staging shows no other evidence of disease. A trucut biopsy reveals a lymphoma showing large cells with mirror image nuclei, lymphocytes, plasma cells and eosinophils. The following phenotype is seen; CD20 positive, CD3 negative, CLA positive, and CD15 positive
A 50 year old male presents with widespread lymphadenopathy. He has had recent fever and weight loss. A trucut biopsy reveals a malignant tumor with the following phenotype; Cytokeratin negative, CLA positive, CD3 positive, and CD30 positive
Which of the following equations is used to determine a positive predictive value?
A 55 year old male presents with a history of chronic dyspepsia and with recent weight loss. Investigation by gastroscopy reveals a reduction in specialised gastric glands and the presence of slender giemsa staining filaments on the mucosal surface. In addition a gastric mass is seen. This is composed of large B lymphocytes which are negative for cyclin D1 and BCL2. Monoclonality is identified.
A 28-year-old woman was found to have stage IV Burkitt s lymphoma. Her renal function was normal and a staging CT scan had shown no abnormality of the renal tract. Three days later, when she was about to start chemotherapy, she developed a temperature of 39.0 C with rigors and was treated with imipenem. Investigations (the following day):serum sodium 138 mmol/L (137 144)serum potassium 6.2 mmol/L (3.5 4.9)serum creatinine 215 mol/L (60 110)serum corrected calcium 1.60 mmol/L (2.20 2.60)serum phosphate 1.52 mmol/L (0.8 1.4)serum lactate dehydrogenase 1238 U/L (10 250)serum urate 0.69 mmol/L (0.19 0.36)What is the most likely cause of the renal impairment?
A 67-year-old man in previously good health is hospitalized because of a 2-day history of fever and diminished consciousness. The patient responds inconsistently to verbal commands. His temperature is 39.5 C (103.1 F); he has tachycardia, and his blood pressure is 80/58 mm Hg. There is no bleeding. His hemoglobin is 12.1 g/dL, leukocyte count is 29,000/ L with 80% neutrophils, and platelet count is 20,000/ L. Which of the following studies should be obtained in this patient?
A 37-year-old man is hospitalized because of fever and right-sided chest pain. He has been having fatigue and recently developed dyspnea on exertion and intermittent chills. At the age of 29 years he was diagnosed with stage III Hodgkin s disease and treated with multiagent chemotherapy and radiation therapy. A year ago, he developed mild anemia with no obvious cause.
