For 10 points, identify these swellings which can be either benign or malignant and may be caused by cancer.
A mutated form of transcription factor c-myc is found in these structures. These structures release molecules like basic fibroblast growth factor to induce poorly-regulated angiogenesis in surrounding microvessels. Complications such as hyperuricemia can occur in their namesake lysis syndrome. When these objects circulate through the bloodstream it is called hematogeneous spread, or more generally metastasis. These bodies often highly express oncogenes, and they are most commonly manifested as carcinomas.
