Abstract

Pituicytoma is a rare low-grade glioma arising from the pituicytes of the posterior pituitary. To date, the clinical and pathological correlates of pituicytoma have not been investigated. This study was thus designed to examine the correlation between pituicytoma and the normal pituitary gland. The records of patients who underwent pituitary surgery at Chang Gung Memorial Hospital in Linkou, Taiwan between 2000 and 2016 were reviewed. Patients who received a pathological diagnosis of pituicytoma were included; however, those with inadequate specimens for pathological study were excluded. Clinical information, including patients' presenting symptoms, serum hormone levels, neuroimages, and specimens, were collected. Hematoxylin and eosin stains and immunohistochemical (IHC) stains were performed for differential diagnosis. Among the 1532 patients who underwent pituitary surgery, nine (0.59%) received a pathological diagnosis of pituicytoma. Two patients were excluded due to inadequate specimens. Among the seven remaining patients, six presented with hormone changes. The IHC stains revealed that pituicytoma has no secretory function; however, the resected pituitary glands showed positive results for hormone change. Coexisting pitu...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
