The common sites for metastasis of renal cell carcinoma are lung, kidney, adrenal glands, liver, and contralateral kidney. We report an unusual case of cutaneous metastasis of renal cell carcinoma in a 68-year-old woman who was treated for renal cell carcinoma with partial right nephrectomy and multikinase angiogenesis inhibitor (sunitinib) 10 years ago.

Ohnishi in 1975 first described temporomandibular joint (TMJ) arthroscopy. Along with its extensive use, a range of complications has emerged. We describe a patient who experienced parapharyngeal swelling after undergoing arthroscopy. Prolonged intubation up to 1 hour postoperatively was required. The swelling resolved completely over 6 h without further(More)
