Epitheloid hemangiomatosis mistaken for carcinomatosis

We present a unique case of intra and extra‐peritoneal epitheloid hemangioma which was mistaken for diffused carcinomatosis, representing a clinical‐pathological problem, and emphasizing the unpredictable behaviour of this tumour. We are dealing with epitheloid vascular tumours, and briefly touch on the differential diagnosis, the principle of biological, pathological and clinical behaviour. Knowledge of this entity would provide an accurate diagnosis and would hence improve dealing with the problem. The conclusion is that this group of Histiocytoid‐epitheloid vascular lesions have varying biological potential and this unusual functional state represents a large spectrum of cells, from normal to neoplastic endothelium.
