Lymphangioma tuberosum multiplex: an unusual variant of lymphangioma

Lymphangioma tuberosum multiplex is a variant of lymphangioma in which there is an abundant proliferation of endothelial cells and dilated lymphatic vessels forming a large, lobulated tumor. A 57-year-old black man developed lymphangioma tuberosum multiplex progressively over a 30-year period following the removal of a smaller tumor from the right posterior flank.
