A 2-month-old infant had right submandibular swelling with inflammation and induration up to the nape of neck. Ultrasonography showed multiple enlarged lymph nodes with soft tissue swelling. Blood cultures grew Gram-positive cocci, which were identified as group B streptococci. Late-onset GBS infection is acquired from colonized household contacts.
The mother of an 11-month-old boy was concerned by a constellation of symptoms including mild fever and rhinorrhea of several day’s duration, lesions that resembled insect bites on one leg and acute swelling of one foot. Early-stage Henoch-Schnlein purpura was suspected. What is your impression?
