Intracystic papillary carcinoma (IPC) of the breast is a rare tumor, and it has a much better prognosis than other types of breast carcinoma (1). Making the preoperative diagnosis of IPC via the clinical examination, ultrasonography and MR imaging is important to plan proper surgical treatment. Several studies have shown that MR imaging of IPC of the breast in a diagnostic setting is sensitive for identifying this malady (2, 3). We experienced a case of IPC that was diagnosed in an 83-yearold-woman. We describe here the clinical findings, ultrasonography and MR imaging that proved to be successful in making an accurate preoperative diagnosis.
Case ReportAn 83-year-old woman had a 5-year history of a mass located in her right breast. She had not received any treatment for the mass because it was asymptomatic. She became aware of enlargement of the mass accompanied with pain and redness of the overlaying skin for the last one month, and she came to our department with spontaneous bleeding due to tearing of the overlaying skin. The physical examination revealed a palpable 8.0 9.0 cm well-circumscribed, firm, mobile, huge mass. Palpation did not reveal any abnormality in the axillary lymph nodes. There was no history of breast trauma.Ultrasonography (US) was performed using a 5 12 MHz linear array transducer and a 5 8 MHz convex transducer (HDI 5000; ATL, Bothell, WA). US of the right breast mass showed a very large complex mass with an anechoic cystic portion, mural nodularity and papillary projections (Fig. 1A). Doppler US demonstrated a flow within the lateral wall portion of the mass and mural nodules (not shown Intracystic papillary carcinoma (IPC) of the breast is very rare, and it has a much better prognosis than the other types of breast carcinoma. We experienced a case of intracystic papillary carcinoma that we diagnosed in an 83-year-old-woman. MR imaging of the IPC shows a multicystic appearance with a subacute or chronic stage of intracystic hemorrhage. The contrast-enhanced MR imaging demonstrates enhancement of the cyst wall and mural nodules, and this modality proved to be successful for making an accurate preoperative diagnosis.
