A 80-Year-Old Woman with B-Cell Prolymphocytic Leukemia.

Prolymhocytic leukemia (PLL) is a rare subtype of lymphocytic leukemias and its cells are immature lymphocytes. It is divided into 2 subgroups: T-PLL and B-PLL according to the lymphocytic origin of the cells. Discriminating B-PLL from other diseases with clinically-similar features is important because of the different treatment approaches and follow-up programs.

VEGF receptor subtypes may serve as novel prognostic factors and putative indicators for anti VEGF receptor treatment response in renal cell carcinoma cases.

Purpose: Targeted therapies are novel treatment options for renal cell carcinoma (RCC). Of the target molecules investigated, vascular endothelial growth factor receptors (VEFGRs) were seldom evaluated. The current study investigated the prognostic significance of VEGFRs and IMP-3 as a potential prognostic markers.

Vascular leiomyomas are composed of smooth muscle cells and vascular endothelium. They are rarely seen in the head and neck region. A 32-year-old woman presented with a slowly-growing pulsatile mass in the right upper jugular region.
