Summary

This case study details pseudofungi in lymph nodes, mimicking true fungi. Careful examination is crucial to distinguish these structures from actual fungal infections in pathology.

Area of Science:

  • Gastroenterology
  • Surgical Pathology
  • Medical Mycology

Background:

  • Gastrointestinal stromal tumors (GISTs) can present as large pelvic masses.
  • Pericolic lymph node involvement is a consideration in advanced GISTs.
  • Accurate histopathological diagnosis is critical for patient management.

Observation:

  • A 45-year-old male presented with abdominal discomfort and pelvic masses.
  • Computed tomography revealed large solid and cystic pelvic masses.
  • Histology confirmed a malignant gastrointestinal stromal tumor.

Findings:

  • Pericolic lymph nodes contained extensive pseudofungi, appearing as septate hyphae-like structures.
  • Periodic acid-Schiff staining was positive, but Gomori methenamine silver staining was negative.
  • These structures were composed of minerals including iron, phosphorus, and calcium, confirmed by various stains and micro-analysis.

Implications:

  • Pseudofungi can be mistaken for true fungal hyphae, leading to diagnostic errors.
  • Distinguishing pseudofungi from true fungi requires meticulous morphologic assessment.
  • Appropriate special stains and advanced analyses are essential for accurate identification and patient care.
