In situ lobular neoplasia of the breast with marked myoepithelial proliferation
Abstract Aims: To present four new cases of in situ lobular neoplasia associated with marked proliferation of myoepithelial cells Methods and Results: Four recently seen cases showing extensive foci of in situ lobular neoplasia, as confirmed by negative E-Cadherin staining, were stained for myoepith...

Marked myoepithelial proliferation was seen around most of the in situ lobular foci or mingled with lobular cells. Conclusions: Marked proliferation of myoepithelial cells is sometimes encountered in association with extensive in situ lobular neoplasia. It is suggested that this proliferation might have a role in maintaining the in situ status of these lesions or, alternatively, that there is a shared factor responsible for the simultaneous proliferation of certain `lobular? cell types and myoepithelial cells. s.shousha@imperial.ac.uk (Shousha, Sami) Charing Cross Hospital, Histopathology - Fulham Palace Road--> - W6 8RF - London - UNITED KINGDOM (Shousha, Sami) UNITED KINGDOM Other/Unknown Material sami The University of Dublin, Trinity College: TARA (Trinity's Access to Research Archive) Histopathology 58 7 1081 1085 |
