A 41-year-old patient presented with fever, night sweats, general malaise, abdominal pain, and substantial weight loss. Laboratory analysis suggested an inflammatory process. Diagnostic imaging revealed a hepatic haemangioma with a diameter of 20 cm. Because such giant haemangiomas of the liver can lead to inflammatory syndrome, the tumour was surgically removed. Pathological analysis confirmed the clinical diagnosis and evidence of extensive thrombosis and other vascular defects was found. Following treatment, the symptoms resolved without further complications. In patients with a giant haemangioma in the liver who present with an inflammatory syndrome, the haemangioma should be considered as the causal factor. For these patients, resection is the treatment of choice.

Primary angiosarcomas of the spleen are rare and almost always fatal. With no more than 200 cases reported in the literature worldwide, no specific risk factors are strongly associated with the disease. The mean age of patients at presentation is 59 years and the major clinical findings include abdominal pain, splenic rupture, and splenomegaly. Grossly, this neoplasm appears as hemorrhagic and/or cystic nodules, with a low-density signal seen on computed tomographic scans. Histologically, the tumor is characterized by neoplastic proliferation with diffuse or focal areas of a vasoformative component with cavernous and arborizing channels. The vascular spaces are lined by endothelial cells with variable degree of atypia. The differential diagnosis includes a variety of benign and malignant vascular proliferations (littoral cell angioma and Kaposi's sarcoma) as well as metastatic tumors. The worst prognostic factor is splenic rupture with early metastasis. The liver is the most common site. We report a case of the 43-year-old woman with a long-standing history of recurrent ovarian carcinoma treated with surgery and multiple courses of radiation therapy and chemotherapy who clinically appeared to have a metastatic ovarian cancer to the spleen and treated with partial resection of stomach and splenectomy. However, histopathologic examination of the specimen showed the tumor to be of a primary angiosarcoma. We believe that the lengthy exposure to radiation may have played a role in the histopathogenesis of this neoplasm in this patient.

Hepatic cavernous hemangioma is the most common benign tumor of the liver. Appropriate management of this tumor remains a controversial topic. We have accumulated a number of cases with successful management of local hepatic tumors. Here we report a case where we performed an ultrasound-guided percutaneous radiofrequency ablation for the treatment of a symptomatic hemangioma. A 36-year-old female patient visited Kyungpook National University Hospital because of persistent right upper abdominal pain caused by an enlarging hemangioma. After two sessions of radiofrequency ablation, the hemangioma was significantly reduced in size. After 36 months, a follow-up abdominal CT revealed remarkably diminished necrotic areas of ablated hemangioma. The size of hemangioma was decreased to almost one third of the original longitudinal diameter. The patient remains asymptomatic in regards to the hemangioma.

Benign solid liver tumors are a heterogeneous group of lesions (adenoma, focal nodular hyperplasia, hemangioma, etc.) with highly varied epidemiological characteristics. Advances in diagnostic methods have improved preoperative diagnosis. Magnetic resonance imaging has become the key test, but there is still a percentage of cases in which definitive preoperative diagnosis is not feasible. The most frequent symptom is abdominal pain, although patients are frequently asymptomatic. Surgery is indicated when diagnosis is uncertain or there are complications (rupture, hemorrhage, etc.). Because of the risk of malignant transformation, adenomas should always be resected. Morbidity and mortality after resection of these tumors is very low since excision is limited, performed in young people without concomitant disease, and in healthy liver.

The case of a 21 year-old female with echinocytosis and a littoral cell hemangioma is reported. The patient had no significant past medical history and presented with abdominal pain and splenomegaly. A large percentage of echinocytes were noted on her peripheral smear in the absence of any known causes. A CT-recognized splenic mass led to splenectomy and a benign hemangioma was found. Red blood cell abnormalities resolved immediately after the surgery. This is the first case reported in the literature of echinocytosis as a consequence of a hemangioma.

Vascular tumors are rare in female genital tract (FGT). The aim of this study was to analyze the distribution of vascular tumors in FGT and to highlight their clinicopathologic features. As a retrospective study, clinical features including imaging studies, gross findings, and microscopic features of cases (ten) diagnosed as having vascular tumors of FGT over 4 years were reviewed. The age range of our cases was 12-52 years. The presenting complaint was abdominal pain/mass, postcoital bleeding, and vaginal and vulval mass. In most cases, duration of symptoms was 6 months to 2 years. Only one case had a long-standing history of 8 years. The vascular tumors occurred most commonly in ovary (six), followed by vulva (two), and one each in cervix and vagina. Clinical diagnoses ranged from cystadenoma in ovarian tumors to endocervical polyp in cervical tumor. Histologically, all were benign vascular neoplasms, ranging from hemangioma (five), lymphangioma (one), lymphangioma circumscriptum (one) to angiomatosis (two) and arteriovenous malformation (one). Thus, we conclude that vascular lesions in FGT can present with symptoms similar to epithelial malignancies and may lead to unwarranted radical surgery. Vascular lesions of cervix and vulvovaginal region pose special problem during pregnancy. Risk of Kasabach-Merritt coagulopathy has to be considered in larger vascular tumors. Most of these cases can be treated by surgery.

We report 2 cases of splenic inflammatory pseudotumor treated by laparoscopic splenectomy. The first patient was a 58-year-old woman who complained of constipation. Computed tomography (CT) showed a well-demarcated mass that measured 4 cm in diameter and was not enhanced. She underwent laparoscopic splenectomy under a preoperative diagnosis of hemangioma. The final histopathologic diagnosis was inflammatory pseudotumor. The second patient was a 29-year-old man who complained of abdominal pain. Computed tomography revealed a demarcated splenic tumor that measured 3 cm in diameter and was not enhanced. Laparoscopic splenectomy was performed. The pathologic and operative diagnoses were both inflammatory pseudotumor. In both cases, the postoperative course was uneventful, and the postoperative hospital stays were 10 and 11 days. Preoperative diagnosis of a splenic inflammatory pseudotumor is very difficult. However, laparoscopic splenectomy is safe and beneficial treatment for this tumor and should be performed in cases in which it is diagnosed.

We present a 42-year-old patient who was examined in the Gastroenterology Department of Gaziantep University for chronic abdominal pain, nausea and vomiting. Ultrasonography showed a 4.7 cm solid hepatic mass on the right lateral side of the right lobe of the liver. The patient was then sent to the Nuclear Medicine Department of Gaziantep University for liver scan. After injecting autologous red blood cells labeled with 740 MBq of technetium-99m ((99m)Tc-RBC), early and delayed anterior planar images of the liver showed no significant findings because of the right kidney shine through the liver. Two days later, after injecting again 740 MBq of (99m)Tc-RBC, we performed a single photon emission tomography (SPET) scan but still this scan was nondiagnostic even in the delayed images of the liver. Three days later, after the iv injection of 185 MBq of technetium-99m-sulphur colloid ((99m)Tc-SC), we observed in the delayed SPET images of the liver, a mismatch defect with decreased focal uptake of (99m)Tc-SC at 60 min while the uptake of (99m)Tc-RBC at the same area was normal or slightly increased. The patient was then operated due to bleeding in the abdominal cavity. A cavernous hemangioma was found, confirmed by histology. The absorbed dose from all three diagnostic scanning procedures was: 4 mSv. In conclusion, the mismatch of the SPET delayed images between the (99m)Tc-RBC and the (99m)Tc-SC scans indicated that this procedure was effective for the diagnosis of liver cavernous hemangioma located in this unusual position.

Although the most frequent benign tumors of the spleen, hemangiomas are very rare, much rarer than hemangiomas of the liver. They manifest as localized (either single or multiple) or diffuse lesions, vary from solid to cystic, histologically from capillary to cavernous. Usually, they are small in size (1-3 cm), rarely larger and very rarely of large size. A 67-year old woman admitted to Institute of Hematology, CCS, for investigation of the left upper abdominal pain, loss of appetite, loss in weight and malaise. As the investigation showed a number of hypoechogenic lesions within the enlarged, diffusely non-homogenic spleen, splenectomy was indicated. The spleen weighing 2600 grams was removed, in which the number of lesions histologically corresponded to hemangioma of the spleen. Postoperative recovery was uneventful. The patient has remained symptom free more than two years after surgery.

Liver hemangiomatosis is defined as extensive hemangioma in the liver. Although hemangioma is the most common hepatic tumor, diffuse hepatic hemangiomatosis is very rare. Most cases of hepatic hemangiomatosis are seen in infancy, but it is extremely rare in adults. This is the first report, showing the enhanced growth of diffuse hepatic hemangiomatosis after hormone replacement therapy. We report herein two unrelated women, 47 and 42 year-old, from different regions of Turkey, who admitted to hospital because of right abdominal pain with diffuse hepatic hemangiomatosis, developed after hormone replacement therapy for menopause. The patients were healthy, except for hemangiomatosis, and their physical examination, routine laboratory tests, and tumor marker levels were within normal limits. It should be noted that their abdominal ultrasonography was normal before hormone therapy, but ultrasonography on admission revealed numerous, ill defined, diffusely located liver nodules in both patients. Dynamic magnetic resonance imaging and scintigraphy have revealed that these lesions are compatible with hemangiomatosis. These results suggest that hepatic hemangiomatosis was induced by estrogen therapy. Consequently, hormone replacement therapy was discontinued, and the patients were followed up for 3 years. Their physical examination and blood chemistry, including liver enzymes, remained within normal range, and the follow-up examination with ultrasonography showed no changes in size of lesions. Because of the possible association of hemangioma with estrogen administration, decisions should be made carefully about estrogen therapy for patients who already have hemangioma, and the periodic ultrasonograpy examination should be planned to detect possible new growth of liver hemangiomatosis.
