Clear cell papillary renal cell carcinoma (CCPRCC) is a rare subtype of renal cell carcinoma (RCC) that has microscopic morphologic features of papillary renal cell carcinoma and clear cell renal cell carcinoma, yet is pathologically distinct based on molecular changes and immunohistochemistry. Pathology
CCPRCC classically has apical nuclei, i.e. the nucleus is adjacent to the luminal aspect. In most glandular structures the nuclei are usually basally located, i.e. in the cytoplasm adjacent to the basement membrane. They typically stain with CK7 and do not stain with TFE3 and AMACR. See also

Ketorolac, sold under the brand names Toradol, and Biorolac among others, is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain. Specifically it is recommended for moderate to severe pain. Recommended duration of treatment is less than six days. It is used by mouth, by nose, by injection into a vein or muscle, and as eye drops. Effects begin within an hour and last for up to eight hours.Common side effects include sleepiness, dizziness, abdominal pain, swelling, and nausea. Serious side effects may include stomach bleeding, kidney failure, heart attacks, bronchospasm, heart failure, and anaphylaxis. Use is not recommended during the last part of pregnancy or during breastfeeding. Ketorolac works by blocking cyclooxygenase 1 and 2 (COX1 and COX2), thereby decreasing production of prostaglandins.Ketorolac was patented in 1976 and approved for medical use in 1989. It is available as a generic medication. In 2018, it was the 192nd most commonly prescribed medication in the United States, with more than 3 million prescriptions. Medical uses
Ketorolac is used for short-term management of moderate to severe pain. It is usually not prescribed for longer than five days,: 291  due to its potential to cause kidney damage. : 280 Ketorolac is effective when administered with paracetamol to control pain in newborns because it does not depress respiration as do opioids. Ketorolac is also an adjuvant to opioid medications and improves pain relief. It is also used to treat dysmenorrhea.
