Rhabdoid tumor of the kidney (RTK) is a rare malignancy in infancy. Central nervous system involvement in RTK is already known. However, solitary spinal metastasis in RTK has been hardly reported. The authors report a case of metastatic RTK to spine causing paraplegia in an 8-month-old girl. Since the patient was young, the diagnosis of spine metastasis was delayed until paraplegia was seen aft...

Metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. Breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. Metastasis from thyroid gland is extremely rare to oral region. We present an unusual case of metastatic follicular carcinoma of thyroid in max...

Laryngeal cancer is the 14th most common malignancy worldwide, and its common subtype squamous cell carcinoma (SCC) is highly associated with tobacco use and long-term alcohol consumption. The incidence of distant metastasis from a primary laryngeal cancer has been reported to be very low, between 6.5% and 8.5%, according to published tumour registry data. Distant metastases of laryngeal SCC mo...

Primary renal malignant fibrous histiocytoma is extremely rare. The prognosis is generally poor because of the high rate of local recurrence even if radical surgery is performed. We report a case of primary renal malignant fibrous histiocytoma in a 43-year-old woman. A well-defined renal mass (10x9x7cm) with lobulated contour was revealed by abdominal ultrasonography and computerized tomography...

Duodenal metastases are a very uncommon and peculiar cause of upper gastrointestinal bleeding. However, they should be considered in a patient presenting with upper gastrointestinal bleeding and a previous history of malignancy. The importance of recognising the unusual presentation of duodenal metastasis has to be emphasised. We describe two patients with upper gastrointestinal bleeding due to...

Choriocarcinoma is a rapidly growing tumor that characteristically outgrows its blood supply. We report a rare case of metastatic choriocarcinoma presenting with acute right flank pain due to kidney rupture secondary to renal metastasis. The renal metastasis was embolised to stanch blood for control of hemorrhage. A brief review of the imaging features and therapeutic options for the ruptured r...

Pleuropulmonary blastoma is a rare childhood neoplasm accounting for less than one percent of all primary malignant lung tumors of children less than six years of age. Metastasis to CNS, orbit and iris, bone, contralateral lung and rarely adrenal glands, liver, kidney and pancreas has been described. This report presents a rare case of pleuropulmonary blastoma with cervical lymph node metastasi...

Metastasis of the kidney carcinoma of leopard frogs (Rana pipiens) has been induced by exposing tumor-bearing animals for approximately 50 days to a constant temperature of 28 degrees C. Under these conditions 54 per cent of the frogs developed secondary growths, whereas in groups kept at 18 degrees or at 7 degrees metastatic dissemination was found in only 6 per cent. Moreover, at the elevated...

Renal metastasis from non-small cell lung cancer is rather uncommon. The mechanism underlying the occurrence of metastasis in this site is still not well understood. We report a case of a 53-year-old Chinese woman who had moderately differentiated squamous cell carcinoma of the lung. After a ten months post-surgery interval of disease free survival, computed tomography (CT) scan found that left...

Bone scintigraphy (BS) is an imaging tool commonly used for screening patients with cancer, especially those with high prevalence of osseous metastases including the breast, prostate, lung, thyroid, and kidney, which account for 80% of osseous metastasis. BS has been shown to be of value in the initial and subsequent treatment strategy of various malignancies. The purpose of this article is to ...
