Granulomatous mastitis in a 50-year-old male: A case report and review of literature.

BACKGROUND: Granulomatous mastitis (GM) an inflammatory disease of the breast that usually affects women of childbearing age, occurs very rarely in males. CASE SUMMARY: We present a case study of a 50-year-old male patient with GM. The patient developed a breast lump following the cleaning of a previously embedded dirt-filled nipple. While an initial improvement was noted with antibiotic therapy, a recurrence occurred a year later, showing resistance to the previously effective antibiotics. Subsequently, the lesion was excised. The histopathological examination confirmed the diagnosis of GM. CONCLUSION: GM should be considered a possible diagnosis of male breast masses.
