Case 5.3.3 Unusual lesions


Case of the month July 2016: Unusual lesions:
Free silicone material in both breasts
Case of the month October 2014: Unusual lesions:
November 2009 Mammography
Unusual lesions:
Infiltrating ductal carcinoma invading a benign fibroadenoma in a patient with multiple fibroadenomas
Unusual lesions:
Thickened nipple that biopsy proved to be a DCIS
Unusual lesions:
Diffuse growing infiltrating ductal carcinoma that could be mistaken for adenosis
Unusual lesions:
Radial scar with an architectural distortion. An ultrasound guided biopsy showed no malignancy. Because of the aspect of the lesion it was r ...
Unusual lesions:
Lesion in the skin that to our complete surprise proved to be an infiltrating ductal carcinoma No other lesions in the breast were found
Unusual lesions:
Lesion in the breast with a mixed echogenicity and without vascularity that puncture proved to be chronic inflammatory changes
Unusual lesions:
Echogenic poorly differentiated adenocarcinoma
Unusual lesions:
Hyperechoic invasive ductal carcinoma
Unusual lesions:
Inhomogeneous mainly hyperechoic infiltrating breast carcinoma with microcalcifications and architectural distortion
Unusual lesions:
Small mainly hyperechoic infiltrating ductal carcinoma with microcalcifications and acoustic shadowing
Unusual lesions:

Unusual lesions:
Diffuse breast abnormality with irregular lactiferous ducts, but without a mass that biopsy proved to be an extensive lobular carcinoma in s ...
Unusual lesions:
Diffuse growing breast carcinoma without a circumscribed mass

Case of the month November 2005: Unusual lesions:
Atypical cyst with a thickened and irregular wall and a stellate lesion that proved to be a carcinoma
Unusual lesions:
Small irregular cyst. A follow up examination showed increase in size and an intracystic mass. Biopsy and cytology of the contents of the cy ...
Unusual lesions:
Lobulated multicystic mass that biopsy proved to be a carcinoma in situ
Case of the month October 2010: Unusual lesions:
Large partly liquefied hematoma that was caused by a small peripheral located carcinoma not detectable in the first examination
Unusual lesions:
Swelling and infiltration of the pectoralis muscle with a thickened hypervascularized muscle mimicking a myositis. Biopsy proved the swellin ...
