Idiopathic granulomatous mastitis masquerading as a postbiopsy abscess

Area of Science:

• Oncology
• Pathology
• Radiology

Background:

• Idiopathic granulomatous mastitis (IGM) is a rare, benign breast disease with an unknown cause.
• It presents with nonspecific clinical and imaging findings, often mimicking breast cancer or infection.
• Diagnosis can be challenging due to its rarity and varied presentation.

Observation:

• A case of IGM is presented in a 42-year-old Turkish woman.
• The condition manifested unusually after a breast biopsy procedure.
• The patient's symptoms were persistent and did not respond to standard antibiotic treatment.

Findings:

• IGM should be included in the differential diagnosis of inflammatory breast conditions.
• It is particularly important to consider IGM in cases of post-biopsy infection that are refractory to antibiotics.
• Exclusion of common conditions like mastitis, carcinoma, and systemic diseases is crucial for suspecting IGM.

Implications:

• This case highlights the importance of considering rare diagnoses in persistent inflammatory breast conditions.
• Awareness of IGM's presentation post-biopsy can lead to earlier diagnosis and appropriate management.
• Further research into the etiology and optimal treatment of IGM is warranted.
