Answer: Bullous impetigo

See the full case at Consultant360

Bullous impetigo is typically due to a staphylococcal infection. Bullous impetigo usually consists of small or large, superficial, fragile bullae. The lesions spread locally in the face, trunk, extremities, buttocks, or perineal regions through direct autoinoculation.

This infection responds rapidly to appropriate antibiotic therapy; it is recommended to treat for the staphylococcal nasal carrier to prevent recurrence.
