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