Amyloidoma: a review and case report.

Area of Science:

• Medicine
• Pathology
• Oncology

Background:

• Amyloidoma is a rare, localized mass composed of amyloid protein.
• It can occur in patients with or without systemic amyloidosis.
• Amyloidomas can manifest in various organ systems.

Observation:

• Three cases of biopsy-positive primary amyloidomas without systemic involvement are presented.
• Case 1: Paraspinal soft tissue amyloidoma.
• Case 2: Multiple primary amyloidomas in the thoracic cavity and flank.
• Case 3: Insulin-injection induced amyloidoma in the left shoulder.

Findings:

• Localized amyloidomas can present as primary disease without evidence of systemic amyloidosis.
• Clinical presentation varies depending on the location and extent of the amyloidoma.
• Insulin injections can potentially induce localized amyloidoma formation.

Implications:

• These cases highlight the importance of considering primary amyloidoma in the differential diagnosis of localized masses.
• Further research into the pathophysiology and clinical management of primary amyloidoma is warranted.
• Understanding the diverse presentations of amyloidoma can improve diagnostic accuracy and patient outcomes.
