title: Occurrence of cutaneous haemangiomas in chickens: Morphological aspects.
abstract: The occurrence of cutaneous haemangiomas in chickens is described. Macroscopi-cally these lesions appeared as a marked redness of the skin, affecting in particular the pericloacal area. Histologically, they resembled capillary haemangiomas, characterized by the proliferation of newly-formed blood vessels. The proliferating cells were of endothelial origin, as demonstrated by ultrastructural observations and by the positivity of the proliferating cells to staining with specific markers (lectins and anti factor VIII-related antigen antibodies).
