Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third most common cause of cancer-related mortality (World Health Organization. Mortality database, 2010). According to the most recent nationwide Japanese registration data, primary liver cancer ranks fourth for men and sixth for women as cause of death from malignant neoplasm (Journal of Health and Welfare Statis...

Epithelioid hemangioendothelioma was coined by Enzinger and Weiss in 1880 to define an intermediate group of vascular neoplasm.1 The tumor is composed of epithelioid or histiocytoid endothelial cells. It commonly occurs in lungs, liver, bone, and presents as a soft tissue mass. Intracranial occurrences are very rare and cavernous sinus is an unusual site. To the best of our knowledge, we found ...

Desmoplastic small round cell tumor is an extremely rare and highly aggressive neoplasm. It usually arises as a single mass or multiple masses in the abdominal cavity, characterized by diffuse peritoneal implants, involvement of regional lymph nodes, and liver and lung metastases. However, bone marrow metastasis has rarely been reported in the literature. We present a case of clinically symptom...

88 subcostal retractions were present. Jugular venous pressure and cardiac examination was normal except for the cardiomegaly which was revealed on percussion. Liver was just palpable below the costal margin and was not tender. X-ray chest revealed enlarged cardiac shadow with cardio-thoracic ratio of 0.80 suggestive of pericardial effusion. 2D Echocardiography confirmed the presence of pericar...

Metastatic tumors involve the oral cavity, and the most common primary sites are the breast and lung. Most cases affect the mandible and maxilla in that order, although some of them can be located in the soft perioral tissues. We report the case of a 62-year-old male who had been diagnosed with sigmoid adenocarcinoma with nodal and liver metastasis, who presented 6 months later with a gingival ...

INTRODUCTION Solid pseudopapillary neoplasm of the pancreas is a rare neoplasm that has been reported to account for between 0.17% and 2.7% of all non-endocrine tumors of the pancreas. It is usually seen in young women. Because solid pseudopapillary neoplasms are rarely aggressive and have low-grade malignant potential and an excellent prognosis after complete resection, it is an ideal pancreat...

Organ transplantation in patients with prior malignancy increases the risk of tumor recurrence post-transplantation due to immunosuppression. Only two cases of liver transplantation have so far been reported in children with hepatic metastases from pancreatoblastoma, a rare malignant neoplasm originating from the epithelial exocrine cells of the pancreas. Herein, we describe a case of a success...

Inflammatory pseudo-tumor (IPT) of the liver is a rare benign neoplasm and is often mistaken as a malignant entity. Few cases have been reported in the literature and the precise etiology of inflammatory pseudotumor remains unknown. Patients usually present with fever, abdominal pain and jaundice. The proliferation of spindled myofibroblast cells mixed with variable amounts of reactive inflamma...

We present a patient of tuberous sclerosis complex with bilateral renal angiomyolipoma and hepatic angiomyolipoma with spontaneous retroperitoneal hemorrhage from right angiomyolipoma (Wunderlich's syndrome). Nephron preserving approach was tried but the right kidney could not be salvaged. Hepatic angiomyolipoma was managed conservatively. Wunderlich's syndrome has been found in around 10% of c...

Biliary cystadenocarcinoma (BCAC) is a very rare malignant cystic neoplasm. Some authors think this particular neoplasm was conversion of biliary cystadenoma over several years of evolution. In the majority of the cases, it habitually occurs in the liver parenchyma (intrahepatic cystadenocarcinoma); sometimes can be observed extrahepatic biliary origin3,4,6,7,8,10,11 extrahepatic biliary cystad...
