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.
