title: Nodular mucinosis of the breast: expanding our understanding with an unusual case.
abstract: Nodular mucinosis of the breast is an extraordinarily rare lesion that occurs in patients who do not have Carney syndrome. Typically, the affected patients are young women with no medical history and a nodule under 1 nipple. Histopathologic examination has, until now, shown a multinodular myxoid lesion containing scattered capillaries and histiocytes but void of epithelial components. We present the case of a 72-year-old woman with a history of mucinous carcinoma of the breast who now presents with a painful subareolar nodule of the same breast. Biopsy and histological examination confirmed nodular mucinosis of the breast.
