A 4-year-old boy developed an erythematous rash around his face and on arms with skin color turning red, during the physical examination swollen lymph nodes around the infection was reported but no other symptoms was seen. Specimen was collected from the infected area, the pathogen isolated was found to be gram-positive bacteria, what could be the possible diagnosis?
Answer: C
Correct answer: Impetigo
Impetigo is a superficial skin infection of young children, typically on the face and exposed limbs, producing erythematous lesions that crust over, with regional lymphadenopathy but no systemic upset. Erysipelas is deeper, with a raised sharply demarcated edge and fever, and cellulitis involves the subcutaneous tissue. The absence of systemic symptoms points to the superficial diagnosis.
