Do hemangiomas grow in internal organs?

Hemangiomas can occur in internal organs, but they are much less common than cutaneous (skin) hemangiomas. They can involve the liver, spleen, lungs, brain, and other organs. Internal hemangiomas can cause serious clinical manifestations depending on their location and size. They may cause functional impairment, bleeding, thrombosis, compression of adjacent structures, and other symptoms depending on the location and size of the lesion.
