Area of Science:

  • Oncology
  • Pathology
  • Radiology

Background:

  • Castleman disease (angiofollicular lymph node hyperplasia) is a rare lymphoproliferative disorder with unknown etiology.
  • It presents with diverse clinical and histological features, posing diagnostic and therapeutic challenges.
  • Unifocal and multifocal forms exist, with the latter exhibiting a more aggressive clinical course.

Observation:

  • A retroperitoneal mass was incidentally discovered in a 38-year-old woman during routine follow-up.
  • The mass measured 9 x 8 x 6 cm on CT, presenting a diagnostic challenge for retroperitoneal masses.
  • CT-guided biopsy yielded inconclusive results, necessitating surgical intervention for definitive diagnosis.

Findings:

  • Histological examination post-excision confirmed the diagnosis of hyaline vascular unifocal Castleman disease.

  • The patient experienced an uneventful postoperative recovery.
  • This subtype typically has a favorable prognosis.

    • Implications:

    • Accurate diagnosis of Castleman disease is crucial for appropriate patient management.
    • Surgical excision can be curative for localized forms of Castleman disease.
    • Multidisciplinary collaboration between radiologists, pathologists, and surgeons is essential for managing rare retroperitoneal masses.
