Hepatic epithelioid hemangioendothelioma (HEH) is a rare tumor. We report on a patient who underwent hepatectomy for malignant HEH associated with abdominal pain due to rapid progression. An 83-year-old man was admitted to Nippon Medical School Hospital because of acute, severe upper abdominal pain. Seven months before admission, a hepatic tumor, 3 cm in diameter, had been detected in the left lateral sector. The diagnosis was hepatic cavernous hemangioma. Abdominal ultrasonography revealed a heterogeneous hyperechoic tumor with a smooth border, 6 cm in diameter, in the left lateral sector (segment 3). Contrast-enhanced computed tomography of the abdomen showed that the tumor was enhanced from the early to the late phase. Abdominal angiography revealed a cotton wool-like appearance of the tumor. The diagnosis was hepatic cavernous hemangioma. A malignancy could not be ruled out because of the tumor's rapid growth, which had caused abdominal pain. Left hepatectomy was performed. Histopathological examination showed necrosis throughout the tumor. Slightly pleomorphic neoplastic cells with rounded, spindle-like nuclei and scant cytoplasm were sporadically found in vascular channels. Intracytoplasmic lumina occasionally contained red cells. Neoplastic cells were positive for factor VIII-related antigen, CD31, and CD34. The Mib-1 index was high. The tumor was diagnosed as malignant HEH. The postsurgical course was uneventful, and the patient was discharged on postoperative day 11. After 3 months, multiple metastatic tumors appeared in right hepatic lobe. Transcatheter arterial chemoembolization was performed.

Hemangioma is the most common benign tumor of the liver and it is often asymptomatic. Spontaneous rupture of liver hemangiomas is a rare but potentially lethal complication. Emergent hepatic resection has been the treatment of choice but carries high operative morbidity and mortality. Recently, preoperative transcatheter arterial embolization (TAE) has been used successfully for the management of bleeding ruptured liver tumors and non-operative treatment of symptomatic giant liver hemangiomas. We report a case of spontaneous rupture of a giant hepatic hemangioma that presented with thoracic and abdominal pain and shock due to hemoperitoneum. Once proper diagnosis was made the patient was successfully managed by TAE, followed by conservative hepatic resection.

We present the case of a 79-year-old female with symptomatic cavernous haemangioma of the liver. The patient had experienced progressive right lateral abdominal pain for years despite increased painkiller use. Surgical resection or transarterial embolisation was not recommended because of the patient's age, cardiovascular comorbidities and large tumour size. Therefore, the patient was treated with 3-dimensional conformal radiotherapy (RT) with a total dose of 30 Gy in 15 fractions. Following RT, the painkillers were tapered from the third month, and complete symptomatic remission was achieved after the ninth month. The measured tumour volume from serial images pre-RT and 3, 9 and 15 months post-RT was 400 ml, 372 ml, 185 ml and 140 ml, respectively. The most dramatic volumetric reduction was found between 3 and 9 months post-RT, whereas the change before or after this period was minimal. The time course of the radiological volumetric changes correlated with that of the clinical symptoms. In addition, the observed vascular changes on serial imaging studies were consistent with the assumed radiobiological effects after fractionated RT.

Littoral cell angioma (LCA) is a rare primary vascular neoplasm of the spleen. A 54-year-old man was referred to our emergency department for abdominal pain. A CT scan showed multiple round hypodense lesions of various sizes throughout the spleen. The spleen was increased in volume. An MRI confirmed the lesion with a suspect of multiple angiomas vs. amartomas. The haematologists excluded any haematological disease. After a collegial discussion, we decided to perform laparotomic splenectomy. Histologically, the multiple lesions consisted in anastomosing vascular channels lined by plump cells. There was an increased number of dysmorphic megakaryocites inside the splenic parenchyma and along the tumour's border, known signs of extramedullary hemopoiesis, whose etiology in our patient was unexplained. To the best of our knowledge this is the third description of the association between littoral cell angioma and extramedullary hemopoiesis. LCA is a rare primary splenic vascular tumour that originates from the splenic littoral cells. The diagnosis of littoral cell angioma is confirmed histologically and on immunohistochemistry. This case report underlines the rarity of this type of benign splenic neoplams, but since the malignant potential of LCA, we recommend close clinical follow- up of patients with LCA of the spleen.

A 55-year-old woman with abdominal pain, trace hematochezia, and anemia underwent 99mTc-labeled RBC scintigraphy to assess for gastrointestinal bleeding. The patient had a remote history of malignant melanoma and had been in a motor vehicle collision 3 weeks prior. The scintigraphic findings were compatible with a giant cavernous hemangioma in the liver. A subsequent contrast-enhanced abdominal CT scan demonstrated venous extravasation into a ruptured liver metastasis.

A 69-year old man came to our hospital complaining of abdominal pain. Contrast-enhanced computed tomography (CT) showed a 65-mm ruptured mass in Couinaud segment 5 of the liver. The mass was treated with emergent transcatheter arterial embolization (TAE), followed by partial hepatectomy. Microscopically, the mass was determined to be an angiosarcoma. Six months previously, enhanced CT had shown a 15-mm mass diagnosed as a cavernous hemangioma in the same region of the liver. Even when the enhancement pattern of a small hepatic mass resembles that of hemangioma, the mass should be reassessed within several months to exclude a diagnosis of hepatic angiosarcoma.

Atraumatic splenic rupture is a rare clinical entity and in the absence of trauma, the diagnosis and treatment are often delayed. In this article the authors discuss a case of a 45-year-old woman, gravida 5, para 4, with spontaneous splenic rupture on her second postpartum day. The rupture was related to a splenic hemangioma that is a vascular malformation and the most common neoplasm of the spleen. Despite the fact that hemangiomas are the most common primary neoplasms of the spleen, only few cases of splenic rupture have been described in pregnancy or puerperium. However, spontaneous splenic rupture is a rare event and the rupture should be suspected in woman with unexplained abdominal pain or with clear signs of haemorrhage.

Littoral-cell angioma (LCA) is a rare vascular tumor of the spleen. It was thought to be a benign, incidental lesion. However, many recent reports have described it to be a malignant lesion with congenital and immunologic associations. We report a case of LCA of the spleen, which has been infrequently communicated in the literature. A 41-year-old female patient was admitted to our hospital with a three-week history of weakness, weight loss, anorexia, and intermittent upper abdominal pain which improved slightly with antacid medication.Imaging studies, including computed tomography (CT) and magnetic resonance imaging (MRI), showed multiple lesions in the spleen. Laparoscopic splenectomy was performed.

Hemangioma, a most frequently encountered primary benign tumor of the liver, is generally determined incidentally during the course of radiologic tests for other reasons. Most lesions are less than 3 cm and a significant proportion of patients are asymptomatic, although the size and location of the lesion in some patients may be associated with the onset of symptoms. Pressure on the stomach and duodenum of giant hemagiomas developing in the left lobe of the liver, in particular, may result in the development of abdominal pain, nausea, vomiting, and feeling bloated, which are characteristic of a gastric outlet obstruction. A 42-year-old man presented with findings of gastric outlet obstruction and weight loss as a result of a giant hepatic hemangioma.

Most hepatic hemangiomas (HHs) are small, asymptomatic and do not require clinical intervention. Surgical resection is only indicated for symptomatic hemangiomas. We report here cases of recurrent HHs in 2 women of 37 and 40 years old, who initially presented with abdominal pain and mass. Radiological examination of each tumor revealed a solitary tumor of 14 and 20 cm in diameter, respectively. Surgical liver segmental resections were performed in both, and the diagnosis of cavernous hemangioma was confirmed. Both patients had recurrent tumor on subsequent radiological examination 4-5 years after the initial surgery. In the first patient, a 15 cm recurrent hemangioma was resected, but multiple hemangiomas were again detected 8 years later occupying the other hepatic lobe, which was not amendable for resection. In the second patient, a 16 cm hemangioma was seen on radiogram, and because the lesion was not symptomatic, conservative observation was offered. Recurrence after liver resection of giant hemangioma is extremely rare. The pathogenesis of tumor progression and recurrence is unknown, as is the management of these patients with recurrent hemangioma, particularly when it is extensive and unresectable.
