Light micrograph of a haemangioma, a benign tumour of vascular tissue which occurs most commonly in the liver (as here) or skin. Routine post-mortem examinations often reveal the presence of a haemangioma in the liver; it appears as a spongy dark red nodule projecting slightly above the surface. Most are cavernous, composed of thick- walled vascular channels lined by flat endothelial cells. Here, many of the channels (purple) contain blood (orange-red). Rarely a liver haemangioma bleeds, but as a rule the lesion is of no clinical significance. Magnification: x40 at 35mm size.
