Purpose:
The goal of this study was to report the ultrasound features of retroareolar breast carcinoma (RABC).
Materials And Methods:
The ultrasound examinations of the breast of 53 women with RABC were reviewed. They had a mean age of 67.2 years±13.4 (standard deviation [SD]) (range: 46-85 years). RABC were defined as carcinomas located less than 2cm from the nipple on mammogram.
Results:
Among the 53 RABC, 42 (42/53; 79%) were invasive ductal carcinomas, 6 (6/53; 11%) were invasive lobular carcinomas, 4 (4/53; 8%) were ductal carcinomas in situ and 1 (1/53; 2%) was intracystic papillary carcinoma. The mean size of RABCs was 22.5mm±8.2 (SD) (range: 7.2-54.8mm). RABCs presented as a mass (53/53; 100%) with an irregular shape (44/53; 83%), a non-parallel orientation (37/53; 70%), non-circumscribed margins (50/53; 94%), a hypoechoic echotexture (46/53; 87%,) posterior attenuation (45/53; 85%) and increased vascularity (37/53; 70%) on Doppler ultrasound.
Conclusion:
On ultrasound, RABC have a presentation similar to that of breast carcinoma in other locations.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
