Introduction: Osteosarcoma (OS) is primary malignant bone tumor in which mesenchymal cell produce osteoid. OS of jawbones is uncommon, representing 4-8% of all OS. Case Report: This paper reports the case of a- 29 year-old female with an OS in mandibular first molar as exophitic lesion with smooth surface during 1 year. Based on the patient's symptoms, differential diagnosis was lymphoma and ...
background: in cancers of prostate, breast, oropharynx, lung, hypopharynx and skin, human tissue kallikreins has been demonstrated as a main role in these problems. there are many research works in which some human tissue kallikreins are expressed in salivary glands. in the present study, the main goal was to determine expression of human tissue kallikreins 4, 8, 10, 11 and 13 in pleomorphic ad...
Sarcomas are malignant tumors of mesenchymal origin. They comprise < 1% adult malignancies and about 15-20% pediatric malignancies. These subdivided into bone cartilage sarcomas soft tissue type. the maxillofacial region 5-10% all this part body. Usually do not originate from benign tumors. Among factors known to induce sarcoma growth are: genetic defects, exposure pesticides herbicides, ionizi...
Liposarcoma is the most common malignant soft tissue tumor in adults. Extremities and retroperitoneum are sites of involvement liposarcoma. gastrointestinal tract rare colon an extremely uncommon site. Mesenchymal tumors bowel mainly represented by stromal (GIST). A sixty-one-year-old male patient presented with abdominal pain distension. Contrast-enhanced computerized tomography (CECT) showed ...
When one follows a systematic approach to make a diagnosis of a malignant lesion, it is relatively easy to render a correct cancer diagnosis in most cases during routine daily practice. The first step is to recognize whether or not the specimen contains a lesion and then to determine whether the lesion is neoplastic or non-neoplastic. As a neoplasm is a clonal proliferation, neoplastic conditio...
objective: gliomas are the most common primary brain tumors, and have been ranked as the fourth leading cause of cancer death. tumor mesenchymal-like stem cells (tmscs) contribute to the aggressive behavior of glial tumors by providing a favorable microenvironment for the malignant cells. the aims of our study were to identify differential proteome of tmscs derived from low vs. high grade gliom...
UNLABELLED Solid tumors are generally composed of two major components: heterogeneous malignant cells and non-malignant stromal part. The latter comprises several types of non-malignant cells of mesenchymal, endothelial and immune origin and together with the extracellular matrix significantly affects the biological properties of the tumor. This minireview is focused on recent advances in the u...
Odontogenic tumors are a heterogeneous group of lesions of diverse clinical behavior and histopathologic types, ranging from hamartomatous lesions to malignancy. Because odontogenic tumors arise from the tissues which make our teeth, they are unique to the jaws, and by extension almost unique to dentistry. Odontogenic tumors, as in normal odontogenesis, are capable of inductive interactions bet...
Introduction: A granular cell tumor is a rare neoplasm originating from mesenchymal tissue. Malignant tumors have poor prognosis. The lung one of the target organs for metastatic malignant tumors. number cases makes managing unknown. Case: 19-year-old male complained shortness breath two months. liver nodule biopsy revealed poorly differentiated carcinoma metastases. Histopathology left manus a...
