title: An ultrastructural study of cutaneous hemangioma in two chickens.
abstract: Cutaneous hemangioma in two laying hens was examined by light and electron microscopy. In close association with capillary and cavernous hemangioma there was a solid cell mass. Ultrastructurally, the cell mass consisted of undifferentiated mesenchymal cells and had an alveolar structure. There were transitional cell types from the alveolar structure to the capillary and cavernous hemangiomas. Hemangiomatous structure may develop from the undifferentiated mesenchymal cells in the solid cell mass.
