Inflammatory pseudotumours, also known as plasma cell granulomas, are benign masses often linked to infections. This case highlights a rare instance of one in the maxillary sinus eroding the orbital wall, mimicking cancer.

Area of Science:

  • Pathology
  • Oncology
  • Otorhinolaryngology

Background:

  • Inflammatory pseudotumours (plasma cell granulomas) are benign, space-occupying masses often associated with recurrent infections.
  • Common presentations include recurrent pain and palpable masses, though their exact nature and pathogenesis remain unclear.
  • These lesions are frequently misdiagnosed as malignant tumors, leading to unnecessary aggressive treatments.

Observation:

  • This report details a rare case of a plasma cell granuloma originating in the maxillary sinus.
  • The lesion presented as a focal erosion of the orbital wall.
  • Clinically, the presentation mimicked that of a malignant tumor.

Findings:

  • The maxillary sinus plasma cell granuloma caused significant local destruction, specifically eroding the orbital wall.

  • Despite the aggressive appearance, the lesion was confirmed as a benign inflammatory pseudotumour.
  • This case underscores the potential for inflammatory lesions to present with destructive features.

    • Implications:

    • Radical surgical intervention is often unnecessary for inflammatory pseudotumours, with excellent prognosis following complete excision.
    • Accurate diagnosis is crucial to avoid overtreatment of these benign conditions.
    • This case expands the known clinical spectrum of plasma cell granulomas, particularly their potential to involve the sinonasal region and mimic malignancy.
