Malignant peripheral nerve sheath tumor (MPNST) is exceedingly rare to occur intracerebrally. The incidence of this subtype 0.001%. Their typical origin from nerves the limbs, trunk, and lumbar brachial plexuses. It carries a poor prognosis despite aggressive management due high chances local recurrence. We present case MPNST occurring intracerebrally in 60-year-old male patient. Imaging showed...

Disruptions in polarity and mitotic spindle orientation contribute to the progression and evolution of tumorigenesis. However, little is known about the molecular mechanisms regulating these processes in vivo. Here, we demonstrate that Polo-like kinase 2 (Plk2) regulates mitotic spindle orientation in the mammary gland and that this might account for its suggested role as a tumor suppressor. Pl...

Myxoid solitary fibrous tumor (SFT) is very rare soft tissue neoplasm. It is microscopically composed of spindle cells which is individually separated by delicate band of collagen fibers. And this tumor cells are immunohisto-chemistrically highlighted by CD34. Myxoid SFT has indolent clinical course and a good prognosis, so it is important to make a diagnosis because of its morphological simila...

Inflammatory pseudotumor (IPT)-like follicular dendritic cell (FDC) tumor is a rare disease with distinct clinicopathological features. We report a case of so-called Epstein-Barr virus (EBV)associated IPT-like FDC tumor of the spleen. We found a splenic mass lesion during his annual checkup. After recognizing the growing mass, splenectomy was performed. Histopathological and immunohistological ...

High levels of mos protooncogene product are expressed during oocyte meiotic maturation and Mos has been implicated in formation of the spindle and spindle pole. Here, we show that in Swiss 3T3 cells with 4N DNA content, high levels of Mos lead to the production of binucleated cells. The Swiss 3T3 cells in mitosis, before binucleation occurs, are anastral and the spindle poles are juxtaposed to...

Sarcomatoid (spindle cell) carcinoma of the pancreas is a rare, high-grade epithelial malignancy composed predominantly or exclusively of spindle cells demonstrating evidence of epithelial derivation, but no features indicative of a specific line of mesenchymal differentiation. The current study presents the case of an 85-year-old Caucasian male with a tumor mass in the body of the pancreas. Th...

granular cell tumors are rare neoplasms of uncertain histogenesis but with a typical histologic appearance composed of cells with characteristic granular cytoplasm. these tumors occur most often in adults as an asymptomatic solitary papule or nodule. multiple granular cell tumors are rare, especially in children and teenagers. we represent a case of multiple granular cell tumors in a 19-year-ol...

background: over recent decades a possible decrease in sperm quality and an increase in the incidence of testicular cancer have been reported in many populations. some recent findings, as cohort studies, showed an increased risk of testicular cancer in men with abnormal semen analysis. case: a 30 years old man referred to our clinic with chief compliant of infertility for 3 years. spermogram re...
