Thrombocytopenia is a common manifestation of tumors, which usually caused by myelosuppression bone marrow involvement malignant tumor cells or radiotherapy. Immune thrombocytopenia (ITP), as paraneoplastic syndrome, more in lymphatic proliferative neoplasms and rheumatic diseases, less solid neoplasms, has not been reported peritoneal epithelioid mesothelioma.Herein, we report 45-year-old pati...

Gastrointestinal Stromal Tumors (GIST) are the common mesenchymal tumors of gastrointestinal tract. They can display benign and malignant clinical behavior. The most common metastasis sites of malignant stromal tumor are liver, peritoneum, lung and bones. Metastasis to breast is extremely rare. Here, we present a case of GIST with liver, bone, lymph node and breast metastasis by reviewing the l...

The knee is a common site for bone tumors, whether clinically painful or not. Conventional radiology has been established as the first line of investigation in patients with knee pain and can reveal lesions that often generate questions not only for the generalist physician but also for the radiologist or general orthopedist. History, image examination, and histopathological analysis compose th...

objective(s): this study aimed to evaluate the role of pretreatment suvmax and volumetric fdg positron emission tomography (pet) parameters in the differentiation between benign and malignant mediastinal tumors. in addition, we investigated whether pretreatment suvmax and volumetric fdg-pet parameters could distinguish thymomas from thymic carcinomas, and low-risk from high-risk thymomas.method...

Adenoid cystic carcinoma (AdCC) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). About 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). Three clinically obvious characteristics of AdCC include slow growth rate, perineural invasion and high incidence of distant metastasis (1). The most commonly-affected sites of...

Introducción: Germinal testicular tumors are the most common malignant neoplasm in men around 20 to 34 years. Even though they unusual, have increased incidence last decade; an excellent prognosis and overall survival at five years, approximately 95%. Divergent data exists regarding treatment options patients with first, second, third relapses conventional therapy. Some studies describe possibl...

Magnetic resonance imaging (MRI) is a radiological imaging method that has not yet found routine application in the detection and assessment of malignant tumors of the maxillofacial region. The aim of this study was to evaluate MRI in the detection, diagnosis and differential diagnosis of malignant tumors of the maxillofacial region. This prospective study included 42 patients with clinically c...

BACKGROUND Although primary bone tumors are relatively uncommon, they constitute the most important tumors in patients less than 20 years. We aimed to determine the frequencies of primary bone tumors and tumor-like lesions of bone and the anatomical sites of their occurrence. METHODS A retrospective review of histopathology reports of all bone specimens received in a private pathology laborat...

introduction one of the important applications of nuclear physics in medicine is the use of radioactive elements as radiopharmaceuticals. metastatic bone disease is the most common form of malignant bone tumors. samarium-153-ethylene diamine tetramethylene phosphonate (153sm-edtmp) as a radiopharmaceutical is used for pain palliation. this radiopharmaceutical usually emits beta particles, which...

background: despite the relative success of surgical resection followed by proton, proton/photon, or conventional radiotherapy in terms of recurrence-free survival, chordomas are still associated with a high rate of recurrence. to our knowledge there are only very few reported cases of this rare tumor detected by f-18 fdg-pet. materials and methods: in this case we show the significance of f-18...
