Nevi are a pigmented benign tumor in the skin but the malignant melanoma is a aggressive malignant neoplasm in the skin. A melanocytic nevus with an atypical epitheloid cell component is a benign neoplasm in skin that can be difficult to distinguish from melanoma. In this study we reported a case of melanocytic nevus with an atypical epitheloid cell component on the upper lip in 24 years old...
background: improvements in imaging techniques has led to an increase in the number of diagnosed pancreatic cysts. although most of the detected cases are benign, a significant percentage of them are malignant or are potentially malignant. currently, endosonography, and analysis of cyst morphology, fine needle aspiration (fna) of the cyst contents, and measurement of the amylase and carcinoembr...
This study presents and tests the clinical validity of a hemodynamic grading system that depends on noninvasive transcranial Doppler ultrasonographic parameters. The suggested transcranial Doppler-based grading system was compared with the Spetzler-Martin anatomic grading for prognosticative validity and clinical dependability. We concluded the following: (1) The pulsatility index was shown to ...
Chloroma or granulocytic sarcoma (GS) is a malignant neoplasm of myeloid lineage that occur in a variety of anatomic sites other than the bone marrow including soft tissue, bone, lymph node, nasal fossa, skin and sometime in the orbit. In the subconjunctiva it is rarely reported. A 4-year-old girl with a history of treated acute myelogenous leukemia was referred to Farabi Eye Hospital, Tehra...
Histological grading is a good parameter to stratify tumors according to their biological aggressiveness. The Elston and Ellis grading method in humans, invasive ductal breast carcinomas and other invasive tumors are routinely used. The aims of this study were classification of mammary gland tumors and also application of a human grading method in canine mammary carcinoma. The samples included ...
OBJECTIVE To examine correlations among nuclear, architectural, and International Federation of Gynecology and Obstetrics (FIGO) grading systems, and their relationships with lymph node (LN) involvement in endometrioid endometrial cancer. MATERIAL AND METHODS Histopathology slides of 135 consecutive patients were reviewed with respect to tumor grade and LN metastasis. Notable nuclear atypia w...
BACKGROUND In patients with neurogenic bladder (NB), elevated intravesical pressures can be transmitted to the upper urinary tract, causing hydronephrosis (HN) and ureteral dilation (UD), which are referred to as upper urinary tract dilation (UUTD). Ureteral obstruction at the bladder wall is another cause for UUTD, but is less of a concern. UUTD can lead to chronic renal failure. Therefore, ev...
Mucin Hypersecreting Intraductal Papillary Neoplasm is a rare neoplasm that arises from ductal epithelial cells. This entity is distinct from the more commonly known Mucinous Cystadenoma or Mucinous Cystadenocarcinoma. Despite this distinction, it has been erroneously categorized with these more common cystic neoplasms. Characteristic clinical presentation, radiographic, and endoscopic findings...
