Acropustulosis of Infancy Clinical Presentation
- Author: Howard Pride, MD; Chief Editor: Dirk M Elston, MD more...
History
The classic history of infantile acropustulosis is an infant aged 2-12 months developing pruritic erythematous macules or papules that progress into vesicles and then pustules. Children are fretful, irritable, and obviously uncomfortable, but otherwise healthy. Individual bouts of infantile acropustulosis last 7-15 days and recur in 2- to 4-week intervals.
Often, children have been empirically treated with antiscabies medicines prior to presentation[4] . The intensity and the duration of infantile acropustulosis attacks diminish with each recurrence.
Physical
The hands and the feet are always involved in infantile acropustulosis, usually on the palms, the soles, and the lateral surfaces. Lesions may occur on the dorsal aspects of the hands and the feet as well as the trunk, the scalp, and the face.
Infantile acropustulosis lesions begin as small macules or papules that then form distinct, noncoalescing vesicles and pustules (see the image below). They heal with macular hyperpigmentation. No other organ systems are involved in infantile acropustulosis,
Lateral and plantar aspects of the foot with a combination of intact acute vesicles and brownish hyperpigmentation of old vesicles. Causes
The cause of infantile acropustulosis is unknown. Scabies as a preceding or concomitant infestation is well documented in some cases. Many children are undoubtedly misdiagnosed as having scabies and treated with lindane or permethrin without any confirmatory scrapings. No other infectious agent has been documented.
