Enormous haemangioma of the liver

Haemangiomas are the most common benign tumours of the liver. Their origin lies in the proliferation of the vascular endothelium. Their growth mechanism is by dilation. They are considered giant when they exceed 5 cm at their greatest diameter. Very uncommon presentations surpass 15 cm; these are known as enormous haemangiomas. We present a case of a 54-year-old woman with an enormous haemangioma of 30 cm in diameter. A mass was present in her right upper quadrant along with dull abdominal pain for several years. It is unknown for how long the tumour had been developing. She underwent surgical management due to evident mass effect. Clinicians should be aware of the importance of early diagnosis in these types of tumours. Its erratic growth pattern, mass effect-related complications and the capacity of producing haematological abnormalities makes it an entity to be considered.
