We describe the case of a 67 year old female with longstanding uterine leiomyomas who presented with fatigue, weight loss, elevated CA-125 and an enlarging mass arising from the posterior uterine fundus. Histologic sections of the mass contained a leiomyoma with interspersed foci of malignant epithelioid cells forming anastomosing vascular channels. The neoplastic cells were diffusely positive for CD31 and FLI1, supporting the morphologic impression of epithelioid angiosarcoma. Few cases of epithelioid angiosarcoma arising within a leiomyoma have been described. In this report we discuss this association and describe its relation with elevated CA-125.

Angiosarcoma of the penis is an exceptionally rare mesenchymal tumor, with only about 30 cases documented in the literature. Because of its rarity and the often nonspecific clinical presentation, histopathological examination plays a critical role in accurate diagnosis. Angiosarcoma of the penis typically arises in the corpus cavernosum but has also been reported in the glans and urethra, often presenting with metastases.

A 54-year-old man presented with a 1-month history of pain and numbness in the right lower limb. Lumbar spine MRI revealed bone metastases. 18F-FDG PET/CT showed a soft tissue mass with increased 18F-FDG uptake in the rectum, accompanied by multiple hypermetabolic lesions in the bilateral ribs, spine, pelvis, and upper right femur.

Aortic angiosarcomas are extremely rare and difficult to diagnose. Here, we report a case of persistent pain and fever of unknown origin, culminating in the diagnosis of aortic epithelioid angiosarcoma at the site of a previous Dacron aortic graft.

Liver masses are common in children, however primary malignant neoplasms are rare, representing only 1% of all pediatric cancers. Hepatocellular neoplasms are the most common primary liver malignancies and hepatoblastoma (HB) is the most frequently diagnosed. The incidence of HB, which is increasing, is approximately of 2 cases per million in the United States, followed by hepatocellular carcinoma (HCC).

Background: Soft tissue sarcomas (STS) are a heterogeneous group of tumors with diverse clinical and molecular characteristics, characterized by limited treatment options and poor prognosis. Immune checkpoint inhibitors (ICIs) have emerged as promising therapies for STS, yet comprehensive evaluations of their efficacy, especially in combination with other treatments, are scarce.
Methods: We conducted a systematic review and meta-analysis of clinical trials on ICIs in STS treatment, sourced from PubMed, Embase, and the Cochrane Central Register of Controlled Trials up to May 31, 2024.
