Pseudomyxoma peritonei: a clinical case of this poorly understood condition.

Background: Pseudomyxoma peritonei is an uncommon condition with an estimated incidence of one to two per million (worldwide) per year. It is characterized by the peritoneal deposition of mucinous tumors, most commonly of the appendix, and occasionally from the ovary, coupled by mucinous ascites.

Case Presentation: We report the case of a 76-year-old woman who presented with increased abdominal girth and dyspnea for 2 weeks.

Hepatic nodule: a case of primary myelofibrosis.

Primary myelofibrosis is one of the entities that may manifest with lesions of extramedullary haematopoiesis, especially in spleen and liver. The authors report a case of primary myelofibrosis presenting incidentally as an intrahepatic focal lesion of extramedullary haematopoiesis, a rare occurrence that highlights the challenge of hepatic nodule differential diagnosis, and allows reflection about the diagnostic criteria and prognostic factors of this myeloproliferative disease.
