A patient with scarlet fever presents with which of the following findings? (Select the option that is NOT a typical feature of scarlet fever)

  1. Pharyngeal lesions and tonsillar exudate
  2. White coating over the tongue followed by 'strawberry tongue'
  3. Spontaneous gingival bleeding
  4. Fever and skin rash (sandpaper-like, erythematous)
Show answer and explanation

Correct answer: C. Spontaneous gingival bleeding

Scarlet fever is caused by Group A beta-hemolytic Streptococcus (S. pyogenes) producing pyrogenic exotoxins. Classic features include: high fever, pharyngitis with tonsillar exudate, 'strawberry tongue' (initially white-coated, then red with prominent papillae), and a diffuse erythematous sandpaper-like skin rash that begins on the trunk. Enanthem (Forchheimer spots) may appear on the palate. Spontaneous gingival bleeding is NOT a feature of scarlet fever — it is associated with vitamin C deficiency (scurvy), blood dyscrasias, or severe periodontitis. Gingival tissues may appear erythematous due to the systemic illness, but spontaneous hemorrhage is not characteristic.
