Chronic Expanding Hematomas: A Clinicopathologic Entity

JAMA. 1980;244(21):2441-2442. doi:10.1001/jama.1980.03310210043026

Chronic expanding hematomas occur in many locations, often simulating neoplasms. All have the same structure with a central mass of blood, a wall of granulation tissue, and dense, fibrous tissue at the periphery. The self-perpetuating expanding nature of the lesion appears to be due to the irritant effects of blood and its breakdown products, causing repeated exudation or bleeding from capillaries in the granulation tissue.
