He finished a cycle of chemotherapy 1 week ago. His temperature is 37.4C 99.4F. Physical examination shows swelling and erythema of both knees and the base of his left big toe. Laboratory studies show:Leukocyte count 13,000mm3SerumCreatinine 2.2 mgdLCalcium 8.2 mgdLPhosphorus 7.2 mgdLArthrocentesis of the involved joints is most likely to show which of the following?? A: Monosodium urate crystals, B: Calcium pyrophosphate crystals, C: Calcium phosphate crystals, D: Gram-negative diplococci, E: Gram-positive cocci in clusters,  <response>: This is a question about a 65-year-old man with chronic myelogenous leukemia who is experiencing pain and swelling in his knees and left big toe. He recently finished chemotherapy. His lab results show elevated leukocyte count, creatinine, and phosphorus. The question asks what is most likely to be found on arthrocentesis of the involved joints.The key facts are:- 65-year-old man - Chronic myelogenous leukemia- Recently finished chemotherapy - Pain and swelling in knees and left big toe- Fever- Elevated leukocyte count- Elevated creatinine and phosphorusThe elevated creatinine and phosphorus indicate possible renal dysfunction, which can lead to hyperphosphatemia. The symptoms and lab abnormalities are most consistent with tumor lysis syndrome, a complication of chemotherapy where the rapid destruction of tumor cells releases intracellular contents into the bloodstream. This can cause hyperuricemia, hyperphosphatemia, hyperkalemia, and hypocalcemia. In tumor lysis syndrome, the elevated uric acid levels can lead to the deposition of urate crystals in the joints, causing gout-like symptoms.A: Monosodium urate crystals
