A 13 year old boy presented with a huge mass on his right arm of 6 months duration. Histopathological examination revealed sheets of malignant small round blue cells with immunopositivity for LCA, CD43, CD45Ro, CD30, EMA, ALK-1 and CD99, and negativity for CD20, TdT, myogenin, myoD1, NSE, bcl-6, bcl-2 and CD10. Fluorescent In-Situ Hybridization (FISH) testing excluded the diagnosis of Ewing's s...
Although the definition of precursor T lymphoblastic lymphoma (T-LBL) is based only on histopathology, most cases cannot be diagnosed only by HE sections. Since 95% of T-LBL expresses TdT and TdT is expressed only in lymphoblasts, immunohistochemical demonstration of TdT is mandatory for the diagnosis of TLBL. However, little is known about the expression of other precursor cell molecules. A 58...
Background Circulating tumor cells (CTCs) analysis is a promising new diagnostic field to estimate risk and monitor treatment efficacy, metastatic relapse, and progression in cancer patients. The study aim was to isolate and characterize CTCs in blood samples of Ewing sarcoma (ES) patients exploiting two main characteristics: CD99 expression and presence of chromosomal translocations. Materia...
یووینگ سارکوما یکی از بدخیم ترین تومورهای کودکان و نوجوانان است. خانواده این نوع تومور از سه گروه یووینگ سارکومای استخوانی، یووینگ سارکومای خارج استخوانی و تومورهای نورواکتودرمال اولیه محیطی (ppnet) تشکیل شده است. مطالعات اندکی، بیولوژی مولکولی این گروه از تومورها را بررسی نموده اند. بنابراین جهت بسط مطالعات قبل ما بیان پروتئینهای p53, ki67,cd99 و fli-1 در بلوک های پارافینی 15 بیمار ایرانی یووی...
Background Urothelial bladder carcinoma (UBC) is usually detected during work-up for hematuria. Cystoscopy and/or contrast-enhanced imaging are the gold standard tools UBC diagnosis, despite limited by being invasive, expensive and low yield in small flat tumors.Objectives To assess diagnostic performance of urine-based DNA methylation six genes (GATA4, P16, P14, APC, CDH1 CD99) detection patie...
The paired immunoglobulin-like type 2 receptor (PILR) family consists of two functionally opposite members, inhibitory PILRα and activating PILRβ receptors. PILRs are widely expressed in various immune cells and interact with their ligands, especially CD99 expressed on activated T cells, to participate in immune responses. Here we investigated whether PILR-derived agonists inhibit β1 integrin a...
