| PURPOSE : To identify the ultrasonographic findings characteristic of pure mucinous carcinoma of the breast.
MATERIALS and METHODS : We reviewed the sonographic findings of 18 nodules in 15 patients which were diagnosed
as pure mucinous breast carcinoma during surgery from January, 1995 to May, 2003. We analyzed the location,
size, shape, orientation, margin, lesion boundary, echo pattern, and posterior acoustic features of the nodules, as
well as changes of the surrounding tissue, associated calcification, axillary lymph nodes, and cystic changes in
the tumor masses. All the patients were female. We also analyzed the preoperative mammographic findings of
the 8 nodules that were available.
RESULTS : The upper inner or upper outer quadrants of the breast were the most common involved sites. The longest
diameter of the tumors was between 0.6 and 5.4 (mean, 2.1) cm. The ovoid shape was most frequently found
(n=14), followed by round (n=2) and, irregular (n=2) shapes. Tumor margins were more commonly well-demarcated
(n=10), followed by obscured (n=8) margins. Most lesions had parallel orientations (n=16) and abrupt
interfaces (n=12). The internal echogenicity was most commonly complex (n=9) followed by hypoechogenicity
(n=6). Most masses showed posterior acoustic enhancement (n=16), associated with posterior acoustic shadowing
in 5 cases. Associated architectural distortion was seen in 3 cases. Microcalcification was associated in 3
cases. Enlarged axillary lymph nodes were associated in 2 cases. Nine masses showed cystic change in the mass.
On mammography, the masses were mostly well-defined (n=3) or obscured (n=3) or, ovoid (n=6) or of a high
density (n=5).
CONCLUSION : On sonography, most mucinous breast carcinoma presented as a well-demarcated ovoid complex echoic
mass with cystic change, and these characteristics were associated with posterior acoustic enhancement
and abrupt interface. |
