We describe a rare intraosseous myoepithelioma, arising in a rib. The patient was a 14-year-old female. The tumor, composed of epitheliod cells and plump spindle cells, was immunopositive for AE1/AE3, S-100 protein, HHF-35, desmin, smooth muscle actin (SMA), CD10, and c-kit, indicating a diagnosis of myoepithelioma. The tumor had invaded surrounding soft tissues, indicating a locally aggressive...

Bacillus Calmette-Guerin (BCG) therapy has been proven to be effective treatment for superficial bladder carcinoma with complications that are usually minor and self limited. Although rare, granulomatous hepatitis can develop, and it is important to recognize it and treat it promptly. The hepatitis which occurs appears to be the result of a hypersensitivity reaction to antigens present in the B...

Epithelioid hemangioendothelioma (EHE) was first described by Weiss and Enzinger in 1982 and has been suggested to be a malignant vascular neoplasm with indolent behavior [1]. A 65-year-old female patient presented to our hospital with fever, back pain and pain in her buttocks. On examination, the only pathological sign were cutaneous nodules appearing in her right thigh (Figure 1 A). The histo...

BACKGROUND AND OBJECTIVE: Video-assisted thoracoscopic surgery is preferred over conventional methods, such as pleural biopsy, in the diagnosis and treatment of patients with pleural effusion. Considering that Imam Khomeini Hospital is facing a large volume of patients with pleural effusion of unknown origin referred from other centers, the present study was conducted to investigate the role of...

Background: Malignant pleural effusion is common in patients with advanced malignant tumor. The aim of this study is to analyze the characteristics of pleural metastasis of renal clear cell carcinoma, pleural effusion under medical thoracoscopy and the diagnostic value of interventional thoracoscopy-guided biopsy, and to improve the understanding of pleural metastasis of renal clear cell carcin...

introduction: different etiologies of pleural effusion are diagnosed based on serum and plural fluid characteristics. the aim of this study was to assess and compare the serum and pleural fluid protein to lactate dehyrogenase (pr/ldh) ratio in exudative pleural effusions. materials and methods: this study was conducted on 60 patients with exudative pleural effusion including: 20 cases with para...

introduction: medical thoracoscopy is a minimally invasive procedure for diagnosing and treating pleural diseases. despite its proven role in diagnostic and therapeutic purposes, it is infrequently used, which could be because of cost of equipment and lack of training. we analyzed our initial 3 years record of thoracoscopy at himalayan institute of medical sciences, a tertiary care center in hi...

Background: Blind percutaneous pleural biopsy has traditionally been performed to investigate the etiology of exudative pleural effusion in which the initial thoracocentesis has been non- diagnostic. In view of the increasing use of image-guided and thoracoscopic pleural biopsies, this study examined the role of blind Abrams pleural biopsy in the investigation of the exudative pleural effusion ...
