PURPOSE Many studies have demonstrated that sporadic microsatellite instability-positive colorectal cancers share several clinicopathologic features with hereditary nonpolyposis colorectal cancers, including right-sided location, young age of onset, characteristic histomorphologic features, and a good prognosis. The aim of this study was to define distinct(More)
Intracranial hemangiopericytoma (HPC) is a rare brain tumor with aggressive biologic behavior associated with high recurrence rate and often with extracranial metastasis. The most common sites of extracranial metastasis of the intracranial HPC are the long bones, lung, liver and abdominal cavity in the order of frequencies. Extracranial metastases usually(More)
BACKGROUND/AIMS Immunoglobulin A nephropathy (IgAN) is a generally progressive disease, even in patients with favorable prognostic features. In this study, we aimed to investigate the antiproteinuric effect and tolerability of low-dose valsartan (an angiotensin II receptor blocker) therapy in normotensive IgAN patients with minimal proteinuria of less than(More)
Brain metastasis occurs in 3.9-24% of patients with renal cell carcinoma (RCC), with an average interval from nephrectomy to brain metastasis of 1 to 3 years. A few cases have been reported where brain metastasis occurred after a delay of more than 10 years from the initial onset of renal cell carcinoma. This long interval for central nervous system(More)
Haglund's deformity is a symptomatic osseous prominence of the posterosuperior corner of the calcaneus creating posterior heel pain and swelling around the insertion of the Achilles tendon. We have experienced an exceptionally huge Haglund's deformity in a 22-year-old female who initially presented to us with a large painful bony heel mass that had(More)
Primary intracranial fibrosarcomas (PIFs) are extremely rare and the origin of these tumors is still controversial. The rarity of primary intracranial fibrosarcomas makes it difficult to diagnose them correctly and establish a standard treatment. The pathologic diagnosis is made by distinguishing findings from light microscopic and immunohistochemistry(More)
