Classification and external resources

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]

Symptoms

LCAs can manifest with splenomegaly, persistent fever and weight loss.[2]

Some patients show no symptoms and the tumours are found incidentally.

Diagnosis

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. Histologically, they have anastoming small vascular channels and cystic spaces with papillary projections.[2]

Treatment

The treatment for a littoral cell angioma is a splenectomy.

If they do not cause the patient any problems, the spleen can remain and the tumours can be monitored for changes with regular CT scans.
