- BTrichomoniasis
- CAtrophic (senile) vaginitis

Show answerHide answer
Answer: D · Bacterial vaginosis
Clue cells are vaginal epithelial cells covered with adherent coccobacilli such as Gardnerella, giving a stippled border. With a thin grey discharge, pH over 4.5 and a fishy odour on adding KOH (whiff test), they fulfil Amsel's criteria for bacterial vaginosis. Metronidazole is the treatment.
- A: Candidiasis shows budding yeast and pseudohyphae.
- B: Trichomoniasis shows motile flagellated trophozoites.
- C: Atrophic vaginitis shows thin epithelium and parabasal cells.
