widespread studies on tumor diagnosis has led to the development of techniques with greater sensitivity and improved specificity for detection of occult and small subclinical tumors. tumor imaging by radiolabeling of tumor-specific antibodies (immunoscintigraphy) or tissue specific biochemical agents (receptor imaging) and especially physiologic imaging with positron emitters (pet), have opened...
Secondary Malignant Neoplasm(SMN) is one of the late effects of childhood cancer. Among secondary malignancies, acute myeloid leukemia(AML) is the most common and life-threatening neoplasm. Secondary acute lymphoblastic leukemia(ALL) is rare and only 10% of SMN is ALL. Patients with Wilm’s tumor are not protected from the secondary cancers after the primary diagnosis. Among patients...
Background: Schwannoma is a peripheral nerve sheath tumor originating from schwann cells. It is the most common neurogenic tumor of the posterior mediastinum. Pleural effusion is a rare presentation of benign schwannoma and it is mainly related to malignant tumors. Histologically, schwannoma as well as solitary fibrous tumor should be considered as a differential diagnosis of spindle cell lesio...
Background: Epithelioid sarcoma is a malignant soft tissue tumor of uncertain histogenesis, categorized as a morphologically distinct neoplasm that characteristically affects the distal parts of the extremities in young adults. In fact, epithelioid sarcoma is the most common soft tissue sarcoma in the hand and wrist. Case report: This 32 year-old male presented with an inguinal swelling, for w...
Widespread studies on tumor diagnosis has led to the development of techniques with greater sensitivity and improved specificity for detection of occult and small subclinical tumors. Tumor imaging by radiolabeling of tumor-specific antibodies (Immunoscintigraphy) or tissue specific biochemical agents (Receptor imaging) and especially physiologic imaging with positron emitters (PET), have ...
Dermatofibrosarcoma protuberans is a tumor of intermediate malignancy characterized by its aggressive local growth and marked propensity to recur after surgical excision. Many forms of the tumor has been reported. We report a pedunculated form of tumor. A 45-year-old woman felt a growing tumor on her trunk for 6 years but did not seek medical consultation until it had ulcerated 6 months ago. Sk...
Medullary thyroid carcinoma (MTC) is a rare tumor arising from parafollicular C-cells. The oncocytic variant of MTC is an extremely rare diagnosis, with less than 20 cases reported. Here we present the case of a 36-year-old male patient with complaints of neck swelling and dysphagia. On fine needle aspiration cytology (FNAC), a Hürthle cell neoplasm was suggested. Finally with histopathol...
Cancer is the major cause of death in the world and the rate of mortality is higher in developed countries. Therefore, lifestyle could be effective in promoting the cancer. The pancreatic tumors, are 8th cause of mortality due to cancer, which have several types, among them ductal adenocarcinoma is the most common and includes 85% of cases. Since, it is almost impossible to diagnosis the tumor ...
primary retroperitoneal mucinous tumor (prmt) of low malignant potential (border line) is an uncommon neoplasm with fewer than 50 reported cases. uncertain diagnostic imaging results make diagnosis of its origin difficult, preoperatively. later treatment planning and prognosis would be affected by exact diagnosis of the tumor origin. this study presents a case of persian woman with diagnostic, ...
