RESUMO
Renal cell carcinoma (RCC) usually remains clinically silent posing a great challenge to early diagnosis. The classic triad of flank pain, hematuria, and flank mass is uncommon and presents in only 10% of cases. RCC is frequently associated with various paraneoplastic syndromes. We report a case of an elderly female with sarcomatoid renal cell carcinoma presenting with acute pancreatitis (paraneoplastic phenomenon), and provide a brief review of the literature. The diagnosis is established on the basis of radiological findings and histopathology.

Kikuchi-Fujimoto disease (KFD) is a benign and self-limiting disease. The entity was first described in 1972 by Kikuchi and Fujimoto in Japan independently. KFD is prevalent in Asia, although it may be seen in a wide geographic distribution. It commonly affects young women. Cervical lymphadenopathy is the most prominent sign and should be differentiated from lymphoproliferative, autoimmune, and infectious diseases. We report a female patient with KFD presenting with enlarged tender cervical lymph nodes and provide a brief review of the literature. The diagnosis is established on the basis of histology of lymph node excisional biopsy.
