Localized AL amyloidosis of the breast in a geriatric female.

Localized breast amyloidosis is often found incidentally on mammography or ultrasound, as amyloid deposits can be calcified and mimic malignancy. Although rare, breast amyloidosis should be considered a possible etiology of abnormal mammography findings in older women.

Breast amyloidosis associated with Sjögren syndrome: A diagnostic pitfall in breast pathology.

BACKGROUND: Amyloidosis is an uncommon disorder characterized by the extracellular deposition of amorphous and insoluble proteins in an abnormal fibrillary configuration. Mammary amyloidosis is an unusual and easily overlooked diagnosis with an ambivalent presentation that could mimic breast cancer. CASE REPORT: We here report the case of 60-year-old Caucasian woman who presented to our surgical oncology department for clinically and radiologically suspicious breast mass. A fine needle biopsy was irrelevant, so we performed a lumpectomy. Final histology revealed an amyloid deposit and further workup was consistent with nodular cutaneous and breast AL amyloidosis associated with Sjögren's syndrome. CONCLUSION: Although rare, an awareness of the clinicopathologic characteristics of this easily overlooked entity is of great importance for breast surgeons.

Slip-Ups in the Diagnosis of Cardiac Amyloidosis: A Case Fatality in Point.

This case report illustrates a tragic example of a "missed diagnosis" of amyloid light-chain (AL) amyloidosis with cardiac involvement that led to progressive heart failure and the ultimate death of the patient. It had a rather atypical presentation in terms of cardiac imaging, although there were certain highly suspicious clinical features, cardiac and otherwise. It also illustrates the importance of selecting the most appropriate assays to establish (or rule out) the presence of monoclonal immunoglobulin consistent with AL amyloidosis, which has a poor clinical prognosis, as unfortunately demonstrated in this case.

Localized primary breast amyloidosis and 1-year changes in imaging: A case report.

Localized primary breast amyloidosis is a very rare benign disease characterized by abnormal protein deposition in the mammary glands. Amyloidosis may mimic the appearance of a number of pathologies, both benign and malignant. Clinically, the patient may present with a breast mass or simply with increased breast density and skin thickening. Herein, we report the case of a 45-year-old woman who presented with a breast mass and was ultimately diagnosed with primary breast amyloidosis, and the mass diagnosed with amyloidosis increased in size and there were a greater number of amorphous and irregular microcalcifications on mammography and ultrasound at the 1-year follow-up. To conclude, we presented changes in a case of localized primary breast amyloidosis on mammography and ultrasound images over a period of 1 year. The current standard of care of primary breast amyloidosis is surgical resection; however, the patient should be followed after surgery to monitor the possibility of recurrence of malignancy.
