Definition / general
Terminology
  • Also called "dust bunnies" or "Gupta bodies"
Epidemiology
  • Rarely identified in Pap Test (< 1%)
  • Can be found in culture of 25% of asymptomatic patients
Etiology
  • Actinomyces Israeli is most common subtype (normal flora of the mouth and bowel)
  • Associated with IUD (common) or rarely with other objects (pessaries, tampon)
  • Copper containing IUD and long term use are major risk factors
Clinical features
  • Asymptomatic
  • Malodorous brown discharge
  • Pain with invasive disease and PID (pelvic inflammatory disease)
Treatment
  • Removal of IUD for asymptomatic women
  • Removal of IUD and antibodies for symptomatic women
Microscopic (histologic) description
  • Tangled clumps of gram positive, non-acid fast, filamentous organisms, often with acute angle branching, sometimes showing irregular wooly appearance
  • Swollen filaments may be seen with clubs at periphery
  • Often cotton ball-like acute inflammatory response
Cytology description
  • Aggregates of pseudofilamentous material, often with acute angle branching
  • May have wooly appearance; periphery may contain swollen filaments with clubs

Differential diagnosis
  • Other filamentous organisms (Leptothrix, Aspergillus)
  • Cockleburs (degenerate radiate crystals associated with pregnancy, IUDs, birth control pills)
