Melorheostosis is a form of hyperostosis which affects both bone and the adjacent soft tissues. Its incidence is variable, although it is higher in the second and third decades of life due to the slowly progressive nature of the disease. It generally presents with pain which may cause significant functional limitation. We may be assisted in its diagnosis by its characteristic radiological image which resembles "wax melting down the side of a candle". A case of melorheostosis is presented with clinical findings and radiological characteristics. The patient had previously been diagnosed with Paget's disease of bone, so we proposed a differential diagnosis of this pathology.

Chylous ascites is caused by an accumulation of lymphatic fluid in the peritoneal cavity secondary to a rupture or obstruction of the abdominal lymphatic ducts. It has a milky appearance and is rich in triglycerides. The most frequent etiologies are neoplasms, liver cirrhosis, and ruptured lymphatic vessels after abdominal surgery. Clinically, it manifests as abdominal distention and increased abdominal girth. The presence of triglycerides in ascites fluid is the most useful diagnostic criterion. Treatment consists of a highprotein diet with fat restriction and medium-chain triglyceride supplements. Surgery is reserved for refractory cases. We present the case of a 66-year-old patient with a diagnosis of chylous ascites secondary to retroperitoneal lymphadenectomy.
