    A pacemaker pocket became a site for plasmacytoma, a rare cancer manifestation. This case highlights potential challenges in diagnosing and treating tumors near implanted cardiac devices.

    Area of Science:

    • Oncology
    • Medical Devices
    • Pathology

    Background:

    • Pacemakers are common implantable devices used to regulate heart rhythm.
    • Plasmacytomas are rare tumors of plasma cells, often associated with multiple myeloma.

    Observation:

    • A 48-year-old male presented with a plasmacytoma in the subcutaneous pocket of a titanium-covered pulse generator.
    • The pulse generator had been implanted 16 months prior to tumor development.

    Findings:

    • The observed tumor was a cutaneous manifestation of myelomatosis (multiple myeloma).
    • The presence of the pacemaker device may complicate the diagnosis and management of tumors in this specific anatomical region.

    Implications:

    • This case underscores the importance of considering unusual tumor presentations in patients with implanted electronic devices.

  • Further investigation into potential interactions between implanted devices and oncogenesis or tumor detection is warranted.
  • Clinical awareness is crucial for timely diagnosis and appropriate treatment of myelomatosis presenting near pacemaker sites.
