Rationale: Schwannoma in the breast parenchyma is very unusual. It usually develops on the head, neck, and extensor surfaces of the upper and lower extremities.
Patient concerns: We report a case of a 60-year-old woman with a palpable and painful mass. Clinically, she experienced neuropathic pain at the mass site.
Diagnoses: The tumor was a 1 cm, well-circumscribed mass, and revealed schwannoma on core needle biopsy.
Interventions: The patient underwent wide excision.
Outcomes: No postoperative complications were observed. A six-month follow-up revealed no recurrence.
Lessons subsections: Although breast schwannoma is a very rare tumor, it is a very important consideration in case of a Breast Imaging-Report and Data System 4A lesion with a painful and palpable mass.
