Undifferentiated pleomorphic sarcoma (UPS), also termed pleomorphic myofibrosarcoma, [1] high-grade myofibroblastic sarcoma, and high-grade myofibrosarcoma, [2] is characterized by the World Health Organization (WHO) as a rare, poorly differentiated neoplasm (i.e., an abnormal growth of cells that have an unclear identity and/or cell of origin). [3]
Sarcomatoid carcinoma is a type of rare lung tumour under the category of poorly differentiated Non-small-cell lung carcinoma (NSCLC). Based on its histological characteristics, it can be classified into giant cell carcinoma (almost completely consists of giant cells), spindle cell carcinoma (almost completely consists of spindle cells), pleomorphic carcinoma (at least 10% spindle/giant cells ...
Pleomorphic rhabdomyosarcoma (undifferentiated rhabdomyosarcoma), also known as anaplastic rhabdomyosarcoma, is defined by the presence of pleomorphic cells with large, lobate hyperchromatic nuclei and multipolar mitotic figures. These tumors display high heterogeneity and extremely poor differentiation.
In the US, July is widely recognized as Sarcoma Awareness Month. [34] The UK has a Sarcoma Awareness Week in July led by Sarcoma UK, the bone and soft-tissue cancer charity. [35] American YouTuber Technoblade was diagnosed with sarcoma in August 2021, and died from his illness in June 2022 after the sarcoma metastasized. He had raised over ...

Women aged 65 are expected to live to 86.9 years, while men of the same age are likely to reach 84.3 years, according to the Social Security Administration's life expectancy calculator.
Four main hypotheses have been proposed for the cellular origins of carcinosarcoma, based largely on the pathology of the disease. [1] [3] First, the collision tumor hypothesis, which proposes the collision of two independent tumors resulting in a single neoplasm, based on the observation that skin cancers and superficial malignant fibrous histiocytomas are commonly seen in patients with sun ...
The Horn-Enterline classification uses morphologic characteristics to divide rhabdomyosarcoma into the embryonal, alveolar, botryoid, and pleomorphic subtypes. [9] However, due to recent advancements in molecular genetics, the genetic and epigenetic factors contributing to these morphological differences have been more closely examined. [9]
