[Kawasaki syndrome in a 9-year-old boy as a result of COVID-19].

Since the beginning of 2020 an increase in a Kawasaki-like disease has been noted. The WHO assumes a connection to the COVID-19 pandemic and it is defined as the multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019.A 9-year-old boy attended the pediatric emergency department with persistent fever and then developed a classical Kawasaki syndrome with affection of the left coronary artery.

Intraoperative and early postoperative chemotherapy into the abdominal cavity using gemcitabine may prevent postoperative occurence of peritoneal carcinomatosis.

Background And Objectives: Malignant tumors of various abdominal organs are blamed to be the cause of death in approximately 40% of cases per year in Western Europe. At the time of death, about half of them show peritoneal carcinomatosis which is considered an unfavorable prognostic factor. In case of peritoneal carcinomatosis, there is no curative treatment available for any of the tumors in the abdominal cavity.

[Value of cytokeratin and Ca 19-9 antigen in immunohistological detection of disseminated tumor cells in lymph nodes in pancreas carcinoma].

Introduction: Based on the fact that pancreatic carcinoma is still associated with poor outcome, the aim of the study was to determine frequency of early tumor cell dissemination using immunohistology in lymph nodes classified as tumor-free by conventional histopathology.

Methods: Fifteen patients with ductal pancreatic carcinoma and 10 patients with carcinoma of the papilla of Vater underwent radical tumor resection (resection status R0, tumor staging pTxpN0M0). In total, 229 lymph nodes classified as tumor-free by histopathology were investigated for disseminated tumor cells using antibodies against cytokeratin and CA19-9.

Hypothalamic osteolipoma: a case report.

The authors present a case of an ossified lipoma at tuber cinerum, an incidental finding when performing an autopsy of a 61-year old male. A tight connection to right communicans posterior artery led first to the diagnosis of a calcified saccular aneurysm, but histologic examination revealed an osteolipoma consisting of mature adipose tissue and formation of bone. Intracranial lipomas are neither hamartomas nor true neoplasms, but they are more likely to be congenital malformations.
