Introduction: Plasma Cell Mastitis (PCM) is a rare, chronic inflammatory breast disorder that primarily affects females, although there are occasional reports in males. This case report details an instance of PCM in a male patient, underscoring the diagnostic and therapeutic complexities associated with this condition.
Patient Concerns: The male patient presented with a palpable parapapillary mass, erythema, and localized breast pain.
Diagnoses: Radiological and histopathological assessments confirmed the diagnosis of PCM.
Interventions: Initial management included conservative pharmacological therapy, which was ineffective. Subsequently, the patient underwent a minimally invasive surgical intervention to address the breast lesion. However, 10 months post-surgery, a recurrence necessitated a total subcutaneous mastectomy.
Outcomes: Despite surgical interventions, the recurrence of PCM highlights the challenges in managing this condition. Complete resolution was achieved following the total subcutaneous mastectomy.
Conclusion: This case underscores the importance of recognizing and addressing PCM in male patients. It highlights the absence of a standardized clinical treatment protocol and emphasizes the necessity for personalized management approaches, especially in recurrent cases.
