Inflammatory pseudotumour is a rare, focal, benign inflammatory lesion of the liver parenchyma. It is largely a self-limiting entity and has favorable prognosis; it is thus important to preoperatively distinguish this lesion from malignancy, which it closely imitates. Inflammatory pseudotumour may present variously. We present the case of a 54-year ...

Epithelioid hemangioendothelioma is a rare vascular neoplasm of uncertain malignant potential. Various reports document metastatic or concurrent epithelioid hemangioendothelioma in several sites, most commonly with combined lung and liver involvement. The concurrent involvement of multiple sites at presentation may cause diagnostic problems because epithelioid hemangioendothelioma can mimic other neoplastic processes. ...
