Ovarian angiosarcoma

•Primary angiosarcoma of the ovary historically has no standard treatment due to its rarity, and outcomes have been variable.•Olaparib may represent a viable treatment option for primary angiosarcoma of the ovary with a somatic BRCA mutation.•Next-generation sequencing may play an important component in treatment of very rare cancers to guide new or uncommon therapies.

BACKGROUND: Angiosarcoma (AS) is a rare and highly aggressive soft tissue disease that most commonly arises in deep soft tissues. There are only a few reported cases of AS involving the ovary and even fewer reports of the underlying molecular abnormalities. Here, we briefly review two cases of primary ovarian AS (oAS) with specific molecular events and immune checkpoints. The clinical features and prognosis of the disease, diagnosis, differential diagnosis, and new treatment approaches are discussed based on a literature review...

Cutaneous angiosarcoma (CAS) is a rare soft-tissue sarcoma of vascular endothelial origin. Paclitaxel (PTX) and docetaxel (DTX) are used as systemic chemotherapy; however, chemoresistance often occurs in CAS. Switching one taxane to the other (i.e., PTX to DTX, or vice versa) is an option when the first taxane is no longer effective in malignant cancers such as ovarian or breast cancer. However, the efficacy of the same strategy in CAS has not been reported. Herein, we report the clinical response of switching one taxane-based chemotherapy to the other in CAS patients with resistance to the first taxane...

RATIONALE: Anastomosing hemangioma (AH) is a rare benign neoplastic vascular lesion that histologically resembles a well-differentiated angiosarcoma. AH commonly involves the urinary system and testes. However, these tumors can also involve the ovaries in some rare cases. This manuscript presents the case of a 28-year-old Chinese woman diagnosed with ovarian AH. PATIENT CONCERNS: The woman was admitted to the hospital with a 4-month history of a right ovarian mass discovered by ultrasound (US) after a spontaneous abortion...

Similar to PAX8, SOX17 was recently identified as a master transcription factor of ovarian cancer based on RNA sequencing data. We explored SOX17 utility in diagnosing ovarian tumors and other gynecologic tumors. We systematically evaluated SOX17 expression on tissue microarrays of 398 ovarian tumors of various types, 93 endometrial carcinomas, 80 cervical carcinomas, and 1371 nongynecologic carcinomas, such as those of kidney, thyroid, breast, colon, bladder, liver, bile duct, adrenal gland, pancreas, brain, and lung and malignant melanoma...

BACKGROUND: Despite increasing reports of thiamine deficiency (TD) among cancer patients, there remain some patients with borderline thiamine concentrations (BTC). However, it is unclear whether such patients subsequently develop TD. METHODS: Here, we report cases of cancer patients progressing to TD within a short time period after presentation with BTC (24-28 ng/ml). CASE 1: A 49-year-old female with lung cancer. During treatment for depression, the patient showed a decreased appetite, and a blood sample revealed BTC (25 ng/ml)...

•A case of concurrent primary ovarian clear cell adenocarcinoma and liver angiosarcoma is detailed herein.•If a liver tumor is found together with ovarian cancer, it is necessary to determine whether this is a primary hepatic malignancy or metastatic liver cancer.•It is important to make a definitive diagnosis by performing a liver biopsy when appropriate.

Collision tumor is a rare entity composed of two different tumors that occur in close to one another and maintain distinct borders. Only few cases have been reported in the breast. We report the first case of concomitant and adjacent primary angiosarcoma (PBAS) and invasive carcinoma of the breast (IBC), in a 45-year-old patient which presented with a lump in her right breast. Biopsy revealed PBAS. She underwent mastectomy. Gross examination showed a hemorrhagic and spongy tumor in contact with a second small grayish-white mass...

Ovarian germ cell tumors composed of numerous well-formed embryonal bodies have been described as exhibiting a "polyembryoma pattern." In addition, some germ cell tumors are occasionally concomitant with neoplastic vascular proliferation. These include angiosarcomas and the recently reported mediastinal vasculogenic mesenchymal tumors. A 9-yr-old Japanese girl underwent surgery for a right ovarian tumor. Histologically, the polyembryoma pattern, nongestational choriocarcinoma, and vasculogenic lesions characterized by a neoplastic repetition of embryonic vasculogenesis have been intermingled...

Epidemiological studies suggest that around 10% of breast cancers are due to hereditary predisposition. The risk of cancer is exponentially increased in patients harboring BRCA1 or BRCA2 mutations. Cumulative breast cancer risk by age 80 is estimated to 72% for BRCA1 mutation carriers and 69% for BRCA2 . The cumulative risk estimates for developing ovarian cancer by age 80 are 44% for BRCA1 mutation carriers and 17% for BRCA2 . We present here the case of a 59-year-old woman who developed a left breast cancer in 2014 treated by conservative surgery, radiotherapy, and endocrine therapy with letrozole...

Recent reports have highlighted a lower-than-expected prevalence of neoplasia in elephants and suggested mechanisms for cancer resistance. But despite infrequent reports in the literature, uterine neoplasia is common in managed Asian elephants ( Elephas maximus ). This study is an archival review of reproductive tract neoplasia in 80 adult female Asian elephant mortalities in managed care facilities in the United States from 1988 to 2019. Neoplasms occurred in 64/80 (80%) of cases. Most were in the uterus (63/64; 98%) with only a single case of ovarian neoplasia...

Epithelioid angiosarcoma is a rare and highly aggressive soft tissue angiosarcoma most commonly arising in the deep soft tissues. Given that abundant vascular cavities anastomose with each other, most angiosarcomas prone to metastasis recur quickly, and the overall prognosis is poor. We report a 25-year-old woman at 24 weeks' gestation who presented with a 1-month history of abdominal distension. Ultrasonography suggested a mass in the right adnexa, and she underwent two operations owing to uncontrolled intraperitoneal bleeding with progressive anemia...

The diagnosis of primary angiosarcoma of ovary is still a challenge as it has no specific clinical symptoms and is easily confused with other malignant neoplasms in morphology. Here, we described a case of primary ovarian angiosarcoma and reviewed the literature. A 47-year-old female showed a left ovary mass. Grossly, the cut surface of the tumor was solid and gray-white with intermediate texture. Some areas were spongy and atropurpureus with a soft texture. Microscopically, the tumor cells were arranged into a variety of different structures with visible hemorrhage...

Many cancer cells share the property of carrying out markedly elevated rates of glycolysis to generate energy even in the presence of sufficient oxygen, and this is known as the Warburg effect. In recent years, there has been a resurgence of interest in the Warburg effect, as the field of oncology has amassed evidence that cellular metabolism may play a prominent role in many neoplasms. Largely in the past decade, another prominent and perhaps surprising factor has emerged in the cancer literature: the catecholamine molecules, epinephrine (adrenaline) and norepinephrine (noradrenaline), appear to play a role in tumorigenesis and metastasis...

RATIONAL: The growing population of young cancer survivors and a trend toward postponing pregnancy until later years in life are leading to a deeper attention towards understanding treatment-induced sequelae, and, in particular, the effects of cancer and/or treatment on fertility. Nowadays, the infertility risks potentially associated with molecular targeted therapies are not established, and clinical reports are sparse. Moreover, the increasing use of molecular targeted drugs in the adjuvant setting and in diseases with better prognosis makes preservation of fertility a major topic in current research...

Ovarian angiosarcoma is a rare and aggressive vascular tumor, which has a 5-year overall survival of less than 30% for patients with nonmetastatic disease and almost certain death within 1 year for those with metastasis. Here, we briefly review historical approaches to therapy and present a long-term survivor in the case of an 11-year-old female with metastatic ovarian angiosarcoma. This is the second reported case to utilize heated intraperitoneal chemotherapy in the treatment of this disease. Our patient is currently alive and well 3 years after initial diagnosis, significantly longer than any reported case of advanced-stage ovarian angiosarcoma...

BACKGROUND: Angiosarcoma is an uncommon high-grade sarcoma in children. Visceral angiosarcoma involving the ovary is extremely rare. Because of the lack of recurrent cytogenetic alterations, histopathological identification of this uncommon tumor in unusual sites like the ovary demands pathologic expertise. Complete surgical resection and radiotherapy are the chief treatment modalities determining survival, with chemotherapy contributing a minor role. CASE: We discuss a 11-year-old prepubertal girl who presented with primary angiosarcoma of the ovary...

INTRODUCTION: Ovarian teratomas undergo the malignant transformation in 0.2-2% of cases. The behavior of malignancies in mature cystic teratomas (MCT) is determined by their phenotype and not their derivation from germ cells. We can recognize pure angiosarcomas or as a part of other tumors like malignant mixed Mullerian tumors and adenosarcomas. PRESENTATION OF CASE: We present the first case of bilateral ovarian angiosarcoma arising from the mature teratomas. Due to widespread disease, we performed limited surgical procedure consisting of bilateral adnexectomy and omentectomy...

Based largely on retrospective analyses and a handful of prospective case reports, pharmacological inhibition of the beta adrenergic receptors using beta blockers has shown clinical anti-cancer efficacy in reproductive cancers, as well as angiosarcoma and multiple myeloma. Because of the potential promise of beta blockers as an adjunct to standard anti-cancer therapy, it is imperative to identify other tumor types expressing beta adrenergic (β-AR) receptors so future preclinical and clinical studies can be directed at the most promising tumor targets...
