A case of intracystic papillary carcinoma accompanying widespread ductal carcinoma in situ.
A 39-year-old Japanese woman noticed a right breast tumor in July 2004. Mammography (MMG) demonstrated an oval tumor without calcification. Dynamic Magnetic Resonance Imaging (D-MRI) demonstrated a high-intensity mass on T2-weighted images, showing mild enhancement during the arterial phase and persistent enhancement during the arterial late phase. Core needle biopsy revealed papillary carcinoma suggestive of Intracystic Papillary Carcinoma (IPC). Auchincloss operation was performed following a partial mastectomy, as the surgical margin after partial mastectomy was positive for carcinoma. Histopathologic mapping of her right breast revealed wide and extensive intraductal spread of DCIS around the IPC. IPC was originally reported to be a localized non-invasive mammary carcinoma. But approximately, half of IPC cases are associated with invasive carcinoma or DCIS beyond the tumor. Careful selection of operative procedure is needed after localized non-invasive IPC or IPC associated with DCIS around the main tumor or invasive carcinoma is diagnosed.
