A pictorial series of interesting and unusual cases of breast malignancy encountered at triple assessment

Content organisation We present a pictorial series of four patients with unusual breast pathology who initially presented to the triple assessment breast clinic in a tertiary university institution. For each case the imaging features and final diagnoses are critically appraised, along with a review of the literature. We illustrate a case reminiscent of bilateral invasive ductal carcinoma which, after further histological immune profiling, is confirmed to be the first presentation of a metastatic lung cancer. A sarcomatoid carcinoma presents as a densely calcified well-defined lesion on mammography accompanying a synchronous invasive ductal carcinoma and could initially have been seen as benign. We present the imaging features of a fibroadenoma which interestingly was shown to contain DCIS. We also highlight the appearances of a recurrent pleomorphic invasive lobular carcinoma within latissimusdorsi muscle following mastectomy and reconstruction.
