Introduction: Tracheal chondrosarcoma (TCS) is a rare malignancy, with only 19 cases described in the literature to date. Case presentation: Herein, we presented the third-largest TCS with such an airway compromise that neither orotracheal intubation nor jet ventilation or even tracheostomy was possible. So, extracorporeal circulation was needed to excise the tumor in a one-stage procedure. Th...

we report the case of a 54-year-old iranian man who presented with melena from three months prior to admission. esophagogastroduodenoscopy and colonoscopy were normal. double balloon enteroscopy showed a pedunculated tumor located in the jejunum. he underwent laparotomy and resection of a 9.5 cm tumor from the distal jejunum. histopathologic evaluation confirmed the diagnosis of an inflammatory...

malignant melanoma of the esophagus is a rare tumor with poor prognosis. the survival of patients is generally less than one year after diagnosis. a case of primary malignant melanoma of the esophagus is presented, who after radical resection of the tumor, is in excellent health, with no evidence of disease 14 months after surgery.

  Abstract   Background: Parosteal osteosarcoma is rare low-grade malignancy which arises   on the surface of the metaphysis of long bones it has a low propensity to metastasize.   Different surgical treatment options including marginal resection, wide resection   and amputation were recommended for the tumor. The purpose of the study was to   assess the results of different surgical treatment ...

Background: Aggressive angiomyxoma is a rare mesenchymal tumor with extensive local invasion. It often presents with a lump in the perineal area and pelvic. Since it often does not involve adjacent organs such as the urethra and anus, does not cause obstructive symptoms. Its incidence is 6 times higher in women than men. This tumor grows slowly and has a slight tendency to metastasize. However,...

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...

Neurofibromatosis type 2 is an inherited disease. The main manifestation of the disease is the development of symmetric, non-malignant brain tumors in the region of the cranial nerve VIII usually as schwannoma. We report here a 20-year-old woman with primary intracranial malignant nerve sheath tumor located in the left cerebellopontine angle. Histologically, the tumor showed malignant spindle c...

In this study, 22 patients (15-75 years old) were selected and transferred to CT scan for tumor ablation. For ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. Then, laser probe inserted through the needle and laser energy delivered. Although we ...
