W. Grayson et al., IMMUNOHISTOCHEMICAL DEMONSTRATION OF PROGESTERONE-RECEPTOR IN HEPATOBILIARY CYSTADENOMA WITH MESENCHYMAL STROMA, Histopathology, 29(5), 1996, pp. 461-463
A case of hepatobiliary cystadenoma with mesenchymal stroma is documen
ted in which unequivocal immunostaining for progesterone receptors was
observed in mesenchymal cells, These cells were negative for oestroge
n receptor, This suggests that the proliferation of the stromal compon
ent may be related to the presence of endogenous progesterone.
