Perivascular epithelioid cell tumours (PEComas) other than angiomyolipoma, clear cell "sugar" tumour of the lung, and lymphangioleiomyomatosis are very rare mesenchymal tumours. The uterus seems to be the most prevalent site of involvement, but only 13 cases of uterine PEComa have been described. Three of these cases exhibited local aggressive behaviour and only one showed metastasis. Because o...

INTRODUCTION Renal angiomyolipomas (AML) are benign neoplasms, arising from perivascular epithelioid cells [1]. They are very rare tumors and are strongly associated with tuberous sclerosis. Their incidence in the general population is very low, approximately 0.3-2.4%, and were des...
BACKGROUND Angiomyolipoma is a benign mesenchymal tumor composed of variable amounts of smooth muscle, adipose tissue and thick-walled blood vessels, and usually named PEComas (perivascular epithelioid cell tumors). PEComas share overlapping histopathological features with epithelioid cells along a perivascular distribution and characteristic immunohistochemistry with coexpression of myoid and ...
