Invasive Lobular Carcinoma: A Review of Imaging Modalities with Special Focus on Pathology Concordance

Invasive lobular cancer (ILC) is the second most common type of breast cancer. It is characterized by a unique growth pattern making it difficult to detect on conventional breast imaging. ILC can be multicentric, multifocal, and bilateral, with a high likelihood of incomplete excision after breast-conserving surgery. We reviewed the conventional as well as newly emerging imaging modalities for detecting and determining the extent of ILC- and compared the main advantages of MRI vs. contrast-enhanced mammogram (CEM). Our review of the literature finds that MRI and CEM clearly surpass conventional breast imaging in terms of sensitivity, specificity, ipsilateral and contralateral cancer detection, concordance, and estimation of tumor size for ILC. Both MRI and CEM have each been shown to enhance surgical outcomes in patients with newly diagnosed ILC that had one of these imaging modalities added to their preoperative workup.

New-onset axillary lymphangioma: a case report

Background

Lymphangioma is a rare diagnosis in adult patients and typically presents in early infancy. These tumors are a result of malformation of the lymphatic vessels and usually involve the head, neck, and axilla.

Case presentation

We report the case of a 28-year-old African female who recently immigrated from East Africa and presented to our surgical breast clinic with a large and rapidly growing left axillary mass. Initial history and evaluation were concerning for hydatid cyst; however, on surgical excision, gross appearance was consistent with cystic lymphangioma. Diagnosis was confirmed on pathology review.

Conclusions

Although lymphangiomas are typically found in young children, adults may develop these tumors in response to unknown triggers. Surgical excision is the preferred treatment.
