PEDIATRIC PRIMARY CARE PNCB 1 EXAM REVIEW QUESTIONS AND ANSWERS, GRADED A+/ A 1 week old has a papular rash, with some clustered lesions, which was first noticed by the caregiver three days ago. A few areas are vesicular. The infant is otherwise healthy. What is the MOST likely diagnosis? neonatal pustular melanosis milia erythema toxicum neonatal acne - -- erythema toxicum Erythema toxicum is a common condition in the newborn period which is described as a papular rash, often evolving into vesicles. It occurs in neonates in the first few days of life up to 2 - 3 weeks of age. Lesions may be clustered, and can recur, but do clear without intervention. Milia is a common lesion in newborns which involves white to yellow papules, usually on the upper body and face and can last for several months. Neonatal acne can be present at birth and involves open and closed comedones. Neonatal pustular melanosis is a rare condition, usually occurring in infants with darker skin tones and is a vesicular rash, involving 2 - 5 mm pustules with a hyperpigmented, nonerythematous base. All of these conditions require no treatment. A 10 year old presents with a 0.2 - 0.3 inch swollen mass centrally located on his left upper eyelid. There is mild erythema and no pain. The MOST likely diagnosis is: external hordeolum coloboma of the eyelid blepharitis chalazion - -chalazion A chalazion is a chronic, sterile, granulomatous inflammation around the meibomian gland. It is usually centrally located along the lid. Although an internal hordeolum (stye) may be located in the same area of the eyelid, clinical findings of the hordeolum include a tender, swollen red furuncle. In contrast, the course of a chalazion includes mild erythema and slight swelling of the lid. After a few days, the inflammation resolves and a painless mass remains. An external hordeolum or stye is found closer to the lid margin. A coloboma of the eyelid is a cleft-like deformity of the eyelid, not a mass. Blepharitis is inflammation of the eyelid margins, and does not present with a mass. A 10-month-old male is irritable and refuses to walk
