[ 5 ] - Laryngeal Leiomyosarcoma, A Case Report and Review of Articles

Laryngeal leiomysarcoma is an extremely rare malignancy originating from smooth muscle cells. Its rarity is due to the fact that only less than 50 cases of pure laryngeal leiomyosarcoma and less than 10 cases of hypopharyngeal leiomyosarcaoma have been reported in modern medical literature.  Even though the clinical presentation mimics that of a laryngeal carcinoma forming the major bulk of the...

[ 6 ] - Nodular Fasciitis of the Auricle: A Case Report

Introduction: Nodular fasciitis is described as a benign reactive proliferation of myofibroblasts. Due to its rapid-growing nature, a precise clinical diagnosis is difficult and the condition is frequently misdiagnosed as malignant lesions.   Case Report: In this study, we present the case of a young woman with an auricular nodular fasciitis as an example of one of the rarest sites of this tumo...

Background & objective: The histologic distinction of small cell from non-small cell lung carcinoma and correct identification of all subtypes of lung carcinoma are very important in treatment management. The main method for histologic classification of lung tumors is based on morphology. However, in small bronchoscopic biopsies in par...

[ 10 ] - Immunohistochemical Study of HER2/neu Overexpression in Adenoid Cystic Carcinoma of Salivary Glands

  Background and Objectives: Adenoid cystic carcinoma (ACC), the most common malignant tumor of submandibular and minor salivary glands, is characterized by a high rate of local recurrence and distant hematogenous metastasis and tendency to invade peripheral nerves. In spite of radiotherapy and surgical treatment, the long-term prognosis is dismal. Today, many studies are being conducted using...

[ 11 ] - Acute Brucellosis with Pancytopenia and Maculopapular Rash

    Human brucellosis is common in developing countries and is a multi-system disease with a broad spectrum of clinical manifestations. Cutaneous lesions associated with brucellosis have been rarely reported in the literature. Here we present a case of a 32-year-old man with history of consumption of cheese made from raw milk seen with occurrence of pancytopenia and diffuse maculopapular rash...

[ 12 ] - Elbow Stiffness Secondary to Elbow Joint Osteoid Osteoma, a Diagnostic Dilemma

We present a 23-year-old man with distal humerus osteoid osteoma referring to our hospital with pain and progressive stiffness. The patient has been suffering from the disease for two years without a certain diagnosis. The radiographies of elbow did not reveal the pathology but further CT scan and MRI studies demonstrated the tumor. The en block resection of the tumor resolved the pain immediat...

[ 13 ] - Absence of FLT3 mutations in Iranian adult T-cell leukemia/lymphoma patients

Background: Adult T cell leukemia lymphoma (ATLL) is a rare disease, significantly linked to the infection by the human T-cell lymphotropic virus 1(HTLV-1). ATLL is typically preceded by decades of clinical latency during which infected cells accumulate selectable traits leading to a malignant transformation. Amongst all the HTLV-1 infected carriers only about 3-5% will develop ATLL. Despite th...

[ 14 ] - Molecular Status of BRAF Mutation in Prostate Adenocarcinoma: The Analysis of 100 Cases in North-East of IRAN

Background and Objective: BRAF mutations were studied in various populations for prostate carcinoma (PC); however, mutations in BRAF gene are unusual compared to KRAS. Oncogenic activating of BRAF mutations were studied lately in almost 0%-10% of prostate cancer cases. Methods: In this retrospective study, we gathered 100 formalin-fixed ...

[ 15 ] - گزارش یک مورد کوریوکارسینوم پس از سزارین

Background: The most common symptom of patients with gestational trophoblastic neoplasia is abnormal vaginal bleeding. Despite repeated visits of patients with postpartum choriocarcinoma and abnormal postpartum hemorrhage, delayed diagnosis leads to advanced disease with widespread metastasis. Therefore, occurrence of choriocarcinoma with variable patterns in different diagnosis of late onset p...

[ 16 ] - Sentinel Node Mapping in Non-small Cell Lung Cancer Using an Intraoperative Radiotracer Technique

 Objective(s): Lymph node metastases are the most significant prognostic factor in localized non-small cell lung cancer (NSCLC). Identification of the first nodal drainage site (sentinel node) may improve detection of metastatic nodes. Extended surgeries, such as lobectomy or pneumonectomy with lymph node dissection, are among the therapeutic options of higher acceptab...
