The case of a 70-year-old woman with progressive renal cell carcinoma (RCC) metastatic invasion of a L3 vertebral hemangioma treated by dual percutaneous radiofrequency ablation (RFA) and vertebroplasty is reported. The patient was surgically treated for RCC in 2001. Chemotherapy and immunotherapy were introduced in 2013 for ovarian, bladder and cerebral metastatic disease. An asymptomatic L3 benign hemangioma was noticed at this time. One-year CT and MRI follow-up studies demonstrated a nodular isolated soft tissue lesion involving the anterior edge of the hemangioma...

The diagnosis of hepatocellular carcinoma (HCC) is based on imaging studies particularly in high-risk patients without histologic confirmation. This study evaluated the prevalence and characteristics of false-positively diagnosed HCC in a liver resection cohort for HCC. A retrospective review was performed of 837 liver resection cases for clinically diagnosed HCC between 2005 and 2010 at our institute. High-risk patients with tumors > 1 cm with one or two image findings consistent with HCC and tumors < 1 cm with two or more image findings consistent with HCC with persistently increased serum alpha-fetoprotein (AFP) levels above the normal range with underlying inhibited hepatitis activity underwent liver resection...

There are some indications that the prevalence of benign and malign neoplasms is increased in patients with a mitochondrial disorder (MID). This study aimed at calculating the prevalence of malign and benign neoplasms in MID patients compared to the general population. Among 103 adult patients with definite or probable MID 16 had a malignancy (15.5%) and 11 (10.7%) a benign neoplasm. Four patients had thyroid cancer, three patients had prostate cancer, two patients each colon cancer, or ovarian cancer, and one each lung cancer, basalioma, Paget carcinoma of the skin, Bowen disease, renal cancer, and urinary bladder cancer...

Ovarian hemangiomas are benign and rare tumors of female genital tract with less than 60 reported cases in the literature. A 38- yr- old woman was admitted to Be'sat Hospital, Tehran, Iran in 2012, due to severe abdominal pain. Ultrasound evaluation revealed a 6 cm left ovarian cystic mass and serum tumor markers were normal. Then, left salpingo-oophorectomy was performed for the patient. Microscopic examination revealed a follicular cyst and an incidental cavernous hemangioma consisting thin-walled vascular channels filled with blood that lined with flatten endothelial cells...

In 2009, Montgomery and Epstein coined the term "anastomosing hemangioma" for a newly described variant of capillary hemangioma with an unusual sinusoidal pattern, histologically mimicking angiosarcoma. The lesion was considered unique for genitourinary system with predilection to kidney but we found in the literature only 4 cases of this entity in ovaries. A 70-year-old woman presented with ultrasound visualized myometrial nodules and cystic formation of the right ovary, intraoperatively diagnosed as serous cystadenoma...

Ovarian hemangiomas are usually of the cavernous type, and are rarely encountered. A 73-year-old woman presented with lower abdominal discomfort. Subsequent physical examination depicted a palpable mass in the lower abdomen. Abdominopelvic computed tomography (CT) revealed a well-circumscribed mass with thin septa measuring 12.1 × 9.0 cm in the right ovary. Levels of the tumor markers cancer antigen (CA)-125 and CA 19-9 were within the normal range. At laparoscopy, the tumor was found to be confined to the right ovary and to have a smooth surface...

β-catenin (CTNNB1) is a key regulatory molecule of the Wnt signaling pathway, which is important for tissue homeostasis and regulation of cell proliferation, differentiation, and function. Abnormal stabilization and nuclear accumulation of β-catenin as a consequence of missense mutations or alternative molecular mechanisms occurs at a high frequency in a variety of epithelial cancers. In mesenchymal neoplasia, the role of β-catenin has been traditionally considered limited to desmoid-type fibromatosis. However, the spectrum of β-catenin-driven (β-catenin-altered) neoplasia of mesenchymal origin has been steadily widening to include, in addition to desmoid tumors, a variety of benign and intermediate-biology neoplasms of soft tissue (intranodal palisaded myofibroblastoma), head and neck (juvenile nasopharyngeal angiofibroma and sinonasal hemangiopericytoma/glomangiopericytoma), and ovarian (microcystic stromal tumor) origin...

Maffucci syndrome is a nonhereditary congenital disorder characterized by multiple enchondromas and with soft-tissue hemangiomas. Somatic mutations of the isocitrate dehydrogenase (IDH) gene have been detected in enchondroma and hemangioma tissue from patients with Maffucci syndrome. The rate of malignant transformation in Maffucci syndrome is high, with enchondromas transforming into chondrosarcomas and the development of secondary neoplasms, including pancreatic and hepatic adenocarcinoma, mesenchymal ovarian tumors, and brain tumors such as glioma...

BACKGROUND: The rearrangements of the 22q11.2 chromosomal region, most frequently deletions and duplications, have been known to be responsible for multiple congenital anomaly disorders. These rearrangements are implicated in syndromes that have some phenotypic resemblances. While the 22q11.2 deletion, also known as DiGeorge/Velocardiofacial syndrome, has common features that include cardiac abnormalities, thymic hypoplasia, characteristic face, hypocalcemia, cognitive delay, palatal defects, velopharyngeal insufficiency, and other malformations, the microduplication syndrome is largely undetected...

Hemangiomas of the ovary are rare with a majority described as individual reports of unusual clinical presentations or morphologic findings. Both the expected and unexpected pathologic features of these tumors in the ovary are not well detailed. Therefore, we collected the largest series of ovarian hemangiomas to comprehensively define their clinicopathologic associations and examine the significance of hormone receptors in their pathogenesis. In addition, a novel EWSR1-NFATC1 fusion has recently been described in a case of hemangioma of bone...

BACKGROUND: Ovarian teratoma with predominant hemangiomatous component in pediatric patients is very rare and its presentation may mimic that of malignancy. CASE: A 2-year-old girl presented with proptosis of the right eye. A right ovarian mass was detected on the physical examination. The right orbital lesion was consistent with venolymphatic-type vascular malformation on magnetic resonance imaging. The abdominal computed tomographic scan revealed a solid ovarian mass that raised a suspicion for malignancy...

Metamifop is a novel herbicide with as yet undetermined properties. To assess its carcinogenicity, metamifop was mixed into standard rodent chow and fed to male and female Wistar rats at doses of 10, 100 and 750ppm for 104weeks. The viability/mortality of these rats was not affected by treatment with metamifop. Treatment had no significant effects on clinical parameters, and food consumption. Males and females fed 750ppm of metamifop for 104weeks showed decreases in body weight and body weight gain. Histopathological examination revealed that treatment with metamifop reduced non-neoplastic findings (chronic progressive nephropathy, tubular basophilia, tubular casts, glomerulosclerosis, basophilic and clear cell foci, senile atrophy, and mesothelial hyperplasia) and reduced neoplastic findings (thymoma, pituitary adenoma, and mammary fibroadenoma and adenocarcinoma in females, and mesenteric lymph node hemangioma in males) compared with control groups...

UNLABELLED: Tumor endothelial marker 1 (TEM1, endosialin) is a tumor vascular marker with significant diagnostic and therapeutic potential. However, in vivo small animal models to test affinity reagents specifically targeted to human (h)TEM1 are limited. We describe a new mouse tumor model where tumor vascular endothelial cells express hTEM1 protein. METHODS: Immortalized murine endothelial cells MS1 were engineered to express hTEM1 and firefly luciferase and were inoculated in nude mice either alone, to form hemangioma-like endothelial grafts, or admixed with ID8 ovarian tumor cells, to form chimeric endothelial-tumor cell grafts...

Ovarian hemangioma is an uncommon ovarian tumor occurring in patients in different age groups. It is usually seen as small, asymptomatic mass, which is detected incidentally. On rare occasions, this type of tumor can be associated with other gynecological neoplasms. In this report, we present the clinicopathologic features of a case of ovarian hemangioma coexisting with multiple microscopic foci of dysgerminoma in a 10-year-old child. The patient presented with acute abdomen. Magnetic resonance imaging revealed a left ovarian mass and subsequent left salpingo-oophorectomy was performed...
