Thymic epithelial reticular cells together with lymphocytes constitute the thymic parenchyma. Morphologically they are characterized by the stellate aspect forming a cytoreticulum, a large and vesicular nucleus, a tonofilament-rich cytoplasm, and abundance of desmosomes. Besides the role of providing a structural support for lymphocytes, epithelial reticular cells are responsible for the secret...

proper differentiation between acral malignant melanoma and benign pigmented lesions like melanocytic nevi is of great value. to avoid unnecessary biopsies, dermatoscopy has been introduced as a non-invasive modality and has improved the clinical diagnostic accuracy in recent decades. we aimed to describe dermoscopic patterns of acral pigmented lesions of patients in the clinic of dermatology i...

OBJECTIVE To compare the apparent diffusion coefficient (ADC) in lymph node metastases of non-small cell lung cancer (NSCLC) patients with standardized uptake values (SUV) derived from combined 18F-fluoro-deoxy-glucose-positron emission tomography/magnetic resonance imaging (18F-FDG PET/MRI). MATERIAL AND METHODS 38 patients with histopathologically proven NSCLC (mean age 60.1 ± 9.5 y) receiv...

Background: Malignant melanoma is the leading cause of death among skin cancers in western countries. However, the incidence, histologic subtypes, and tumor behaviors are quite different in Asians and western populations. Objective: This study was designed to survey the clinicopathological aspects of malignant melanoma among Khouzestan people. Patients and Methods: In a retrospective stud...

Abstract Background and Objectives Cervical lymph node enlargement is observed in various diseases, including malignant lymphoma (ML). Open biopsy of the enlarged frequently required for diagnosis, especially when ML suspected. Serum levels soluble interleukin 2 receptor (sIL-2R) may be useful as a biomarker ML. This study aimed to determine whether measurement serum sIL-2R might diagnose Mater...

In recent years, ultrasound scanning has become an important diagnostic tool in dermatology. It is easy to use, completely safe, and provides important diagnostic information. There are 2 basic types of ultrasonography with dermatologic applications. The best established is 20-MHz scanning, which can be used to measure tumor thickness and/or skin thickness when treating inflammatory diseases su...

T HE INTRODUCTION of a miew technic iisto medical science commonly goes through three phases : a period of emithusiasm, a period of rejectiomi ( which sometimes may not be overcome), and a period of reasonable appreciatioms. Electron microscopic cytology has now reached the third state. Enthusiasm has beets justified since resolution power has beets pushed from 3000 A to less thami 30 A ; rejec...
