Neonatal pustular melanosis or Transient Neonatal pustular melanosis

Other Terminologies:
1.Transient neonatal pustulosis
2.Transient Neonatal pustular melanosis
3.Lentigines neonatorum


It is a benign cutaneous condition that presents at birth with 1- to 3-mm flaccid, superficial fragile pustules, some of which may have already resolved in utero, leaving pigmented macules.

It has distinctive features characterized by vesicles, superficial pustules, and pigmented macules. The lesions of transient neonatal pustular melanosis are present at birth.

Commonly seen: On the chin, neck, forehead, chest, buttocks, back, and on the palms and soles

Self resolves in about 2 days. More common in dark skinned neonates.

Diagnosis: Usually Clinical. A Tzanck smear with a cellular stain (eg, Wright-Giemsa stain) or Gram stain of the contents of a pustule reveals a predominance of neutrophils and occasional eosinophils and cellular debris
