Littoral cell angioma, abbreviated LCA, and formally known as littoral cell angioma of the spleen, is a benign tumour of the spleen that arises from the cells that line the red pulp.[1]
LCAs most often are not clinically detectable. On occasion, their first presentation may be with splenic rupture.[2]
Most patients show no symptoms and the tumours are found incidentally.
Littoral cell angiomas show in CT scans. They are diagnosed by pathologists by taking a sample of the tumour via Fine Needle Aspiration or Core Needle Aspiration or from a splenectomy. Histologically, they have anastoming small vascular channels and cystic spaces with papillary projections.[2]
The treatment for a littoral cell angioma is a splenectomy.
