[ 1 ] - Langerhans Cell Histiocytosis Followed by Hodgkin Lymphoma: A Case Report
Langerhans cell histiocytosis (LCH) is a rare neoplasm defined as the proliferation of bone marrow langerhans cells, which is a kind of dendritic cells. The major pathological features of LCH are expression of CD1a and S100 as well as Birbeck granules. Its presentation can differ from a mild bone lesion to a multi-systemic evolved malignant neoplasm; however, the latter outcome is almost rare. ...
[ 2 ] - Bone Marrow and Karyotype Findings of Patients with Pancytopenia in Southern Iran
Background: Pancytopenia is a manifestation of a wide range of disorders. The main prognostic factor for predicting outcome and response to treatment is based on the underlying cause. To detect the root cause of this problem, depending on other accompanied signs or symptoms, the need for bone marrow examination and other advanced work ups is different at least at the practical level. This study...
[ 3 ] - Expression Status of UBE2Q2 in Colorectal Primary Tumors and Cell Lines
Background: Activation of the ubiquitin-proteasome pathway in various malignancies, including colorectal cancer, is established. This pathway mediates the degradation of damaged proteins and regulates growth and stress response. The novel human gene, UBE2Q2, with a putative ubiquitin-conjugating enzyme activity, is reported to be overexpressed in some malignancies. We sought to investigate the ...
[ 4 ] - Cytogenetic Findings of Patients with Acute Lymphoblastic Leukemia in Fars Province
Background: Acute lymphoblastic leukemia (ALL) is the sixth most common malignancy in Iran. Cytogenetic analysis of leukemic blasts plays an important role in classification and prognosis in ALL patients. The purpose of this study was to define the frequency of chromosomal abnormalities of ALL patients in adults and children in Fars province, Iran.Methods: In this cross-sectional study, we eval...
[ 5 ] - Evaluation of Ki67, p16 and CK17 Markers in Differentiating Cervical Intraepithelial Neoplasia and Benign Lesions
Background: Cervical intraepithelial neoplasia (CIN) is a premalignant lesion capable of progressing to cervical cancer. Despite the existing well-defined criteria, the histomorphologic diagnosis is subject to high rates of discordance among pathologists. The aim of this study was to evaluate Ki-67 (MIB-1), CK17 and p16 INK4a (p16) markers by immunohistochemical methods in differentiating CIN f...
[ 6 ] - Immunohistochemistery Study in a Case of Neph-rogenic Adenoma of Bladder
Nephrogenic adenoma is a rare benign lesion of bladder that may be confused with malignant lesions. There is a strong relation with urinary tract irritation and intravesicle instrumentations. Nephrogenic adenoma was initially thought to originate from urothelial metaplasia; however, no solid proof is available. We present a case of 55-year-old lady with urinary problem. Cystocopic examination ...
[ 7 ] - Disseminated Peritoneal Leiomyomatosis
Leiomyomatosis peritonealis disseminata is a very rare condition characterized by the development of multiple smooth muscle-like nodules in the peritoneal cavity. It is associated with increased serum levels of gonadal steroids. The present report describes a 29-year-old patient underwent transabdominal hysterectomy and Bilateral Salpingo oophorectomy six years ago because of leiomyomatosis per...
[ 8 ] - Blastic Plasmacytoid Dendritic Cell Neoplasm; A Report of Three Cases
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematodermic myeloid malignancy that is known to be derived from plasmacytoid dendritic cells which are characterized by expression of CD4, CD56, and more specific markers such as CD123. Here, the authors present three cases of BPDCN diagnosed in the past two years and address different available diagnostic modalities such as morpho...
[ 9 ] - Dicer Gene Expression as a Prognostic Factor in Acute Lymphoblastic Leukemia and Chronic Lymphocytic Leukemia in Fars Province
Alterations in the expression of microRNAs (miRNAs) have been proposed to play a role in the pathogenesis of acute lymphoblastic leukemia (ALL) and chronic lymphocytic leukemia (CLL). Dicer is one of the main regulators of miRNA biogenesis, and deregulation of its expression has been indicated as a possible cause of miRNA alterations observed in various cancers. Our aim was to analyze the expre...
