:: X-Ray 1 ::MLO image right breast from 3/09
:: X-Ray 2 ::CC view right breast from 3/09
:: X-Ray 3 ::MLO view right breast 09/09 - pt presents with palpable lump
:: X-Ray 4 ::CC view right breast 9/09 - pt presents with palpable lump
:: MRI 1 ::MRI demonstrating the lesion which was biopsied under US guidance right lateral chest wall

:: X-Ray 5 ::SC CC view of the palpable mass - no focal abnormality seen
:: Ultrasound 3 ::Companion case - palpable mass, consistent with hyperechoic mass seen on US with irreuglar margin - Histology: colloid cacrinoma
:: Ultrasound 1 ::US right breast - palpable area - demonstrates hyperechoic - well circumscribed mass Discussion: Unusual presentation of an invasive breast cancer - unusual, due to its location within the chest wall about 5 cm lateral from the breast (area not covered on standard MLO and CC view) - unusual because of its presentation as an hyperechoic mass seen on US Companion case shows also a palpable "hyperechoic mass" which is more irregular in margin and turns out to be a collloid carcinoma - these tumors can present as a fairly hyerechoic mass (also called mucinous type invasive ductal carcinoma) Differential diagnosis: soft tissue tumor such as lipoma - focal infection (sebacceous cyst) - breast cancer - Diagnosis confirmation: Surgery / Histo Category: Other Region / Organ: Thorax-Muscular system / Connective tissue / Skin Etiology: neoplastic References: Get more for Invasive ductal carcinoma Peer-reviewed resources Literature  More publications about Invasive ductal carcinomaChallenge yourself with the case quiz! |
