title: Myopericytoma of the liver hilus: a case report.
abstract: Pericytic tumours is a new category recently introduced in soft tissue pathology describing those entities sharing evidence of myoid differentiation and a tendency of spindle or more rounded cells to grow in a perivascular fashion. The great majority of pericytic tumours are benign but recurrence has been described as well as very rare malignant cases with an aggressive behaviour. Although pericytic tumours arise most commonly in the subcutaneous tissue of distal extremities in middle age patients, additional cases have been recently described in many other organs. Here we describe a case of a 57-year-old man with an 8.5 cm mass of the liver hilus diagnosed as myopericytoma, with particular reference to its biological potential and differential diagnosis. It is important for the pathologists to take this diagnosis into consideration as well for a better management of patient care.
