The exhibit displays hemangioma with a classical cut surface showing red brown colour. The vascular spaces filled by red blood cell can be appreciated.

Capillary hemangioma composed of proliferation of small sized of blood vessels arranged in lobules separated by fibrous septae.

Sebaceous adenoma shows well circumscribed, nodular growth of lobules consist of admixture of basaloid cells and mature sebocytes. Some lobules may communicate directly with the surface epithelium. Basaloid cells are usually located at the periphery of lobules and sebaceous cells with intracytoplasmic lipid vacuoles, which are usually located at the center of lobules. They are composed of expanded germinative layer, with more than the normal 2 cell layers seen in mature sebaceous glands or sebaceous hyperplasia but still less than 50% of the tumor volume.
