If the membrane that surrounds the mast cells is too weak, it will easily and rapidly break down under physical pressure, which then causes an allergic ...
Tenosynovial giant cell tumor (TGCT) is a non-malignant tumor defined histologically as inclusions of “osteoclast-like” multinucleated giant cells, hemosiderin, and macrophages. [1] This histology can present one of 2 clinically distinct ways. TGCT tumors often develop from the lining of joints (also known as synovial tissue).
