ABSTRACT
A26 year old multiparaous Yemeni lady presented during the 3rd trimester of her pregnancy with multiple painless rapidly enlarging bilateral breast and axillary masses with erythema of the overlying skin. Histopathological examination of both breast and axillary masses revealed lactating adenomas although uncommon are the most prevalent breast masses seen in pregnant women. they could be single or multiple and can occur in the breast or in ectopic locations in this case the lesions were multiple bilateral occurring simultaneously in the breast and ectopic locations and reaching enormous proportion [11cm in diameter] with associated overlying engorgement and erythema thus raising the possibility of malignancy lactating adenomas are benign lesions and most show spontaneous involution however the diagnosis is not always straightforward and surgical resection may be required for definitive diagnosis and exclusion of other pathologic processes
