Lab 3j Cavernous Hemangioma of the Liver (56000-91200)

The cavernous hemangioma is the most common benign tumor of the liver, occurring at all ages and in both sexes. The majority are asymptomatic, but occasionally they may cause vague abdominal symptoms following episodes of thrombosis. Even more rarely, they may rupture and cause intraperitoneal hemorrhage.

Slide 1  Grossly, most hemangiomas are solitary and under 5 cm in size. This is a particularly large one, measuring about 9 cm. in greatest dimension. It is a soft pulpy, hemorrhagic mass with a spongy consistency.
Slide 2 This is a low power view showing the junction of the normal liver (L) at the left with the hemangioma (h) at the right.
Slide 3 The tumor is composed of endothelial-lined, blood-filled cavernous spaces separated by a fibromyxoid stroma.
