The rose among the thorns: A rare and harmless mimic of a spiculated breast mass

Masses with spiculated margins are highly suspicious and classified as breast imaging reporting and data system 5, with a predicted malignancy risk exceeding 95%. However, some benign causes can also produce these spiculated masses. It is often difficult to determine the cause of a spiculated mass based solely on imaging, requiring biopsy and excision for radiopathological correlation. In this article, we discuss a rare benign cause of a spiculated mass on mammography, plasma cell mastitis, which mimicked malignancy and was managed with biopsy and subsequent surgery due to radiopathological discordance.
