The peel of newborn babies plays a cardinal function in the transition at birth from an aqueous to a predominantly dry out environment. Newborn pare is characterized by a relatively thin stratum corneum, the absenteeism of dermal ridges and well-adult collagen fibrils within the papillary dermis, a composition distinct from that of subcutaneous fat, and an immature cutaneous vascular organisation.one

Due to the immaturity of the cutaneous components a series of specific cutaneous reactions occurs during the first few weeks of life, giving rise to a condition known every bit transient beneficial cutaneous lesions of the newborn. It is important to recognize these reactions and not to confuse them with infections or signs of internal or genetic diseases in social club to avert alarming parents and performing unnecessary tests and treatments.1,2

This letter describes the case of a 1-calendar month-old babe who presented hyperpigmented lesions that followed the pare folds of the abdomen, consequent with a diagnosis of transient pigmentary lines of the newborn.

The patient was a 1-month-old male person baby who had been referred for cess of abnormal pigmentation of the abdomen that had been present since birth. He had been born by unassisted vaginal delivery at 39 weeks of gestational age, and had no built abnormalities. No physiological scaling or other transient cutaneous lesions were observed in the first days of life, and there was no family history of similar cutaneous lesions.

Physical examination revealed 4 horizontal hyperpigmented lines that followed the peel folds of the abdomen. Apart from hyperpigmentaion of the navel, no other lesions were observed (Fig. 1). The infant'south growth and development were normal.

A diagnosis of transient pigmentary lines was established and the parents were informed of the transient nature of the condition. In the post-obit 4 months, without treatment, the linear hyperpigmentation gradually faded and disappeared, and normal skin color was restored.

Transient pigmentary lines were outset described by Gibbs in 1967.three This rare condition, one of several forms of transient benign cutaneous lesions that affect newborns,1 is referred to in the literature by several terms, including striped hyperpigmentation of the torso,three,four pigmentary lines of the newborn,5,6 and transient infantile patterned hyperpigmentation.viii By searching the PubMed database using the search terms pigmentary lines, pigmentary transient, striped hyperpigmentation, and transient hyperpigmentation nosotros plant only vii other cases consistent with this entity (Table 1).3,5–8 The condition is characterized by the appearance at birth of several horizontal bands of hyperpigmentation that follow the pare folds of the belly, back, or limbs. These bands subsequently fade spontaneously and resolve fully by 2 to 8 months of age. They near commonly affect black or dark-skinned male neonates, and are rare in white infants. Transient pigmentary lines tin be associated with abnormal cornification (ichthyosis vulgaris and collodion infant)3,iv and pigmentation (vertical linear hypopigmentation of the abdomen,5 hyperpigmentation along the spine,7 and mottled hyperpigmentation of the back7).No associated extracutaneous anomalies accept been described. The etiology and pathogenesis of transient pigmentary lines are unclear; its origin is not thought to exist hormonal, but rather a effect of friction or impaired exfoliation of the embryonic pare, accentuated past the flexed position of the fetus (mechanical trauma associated with hyperkeratosis within the peel folds).3

Newborns and infants can exist afflicted past multiple processes that involve altered pigmentation.9,10 The differential diagnosis of transient pigmentary lines includes hyperpigmentation secondary to built adrenal hyperplasia, possibly caused past cantankerous reactivity of adrenocorticotropic hormone with melanocyte-stimulating hormone (MSH) receptors.1 It should also exist distinguished from transient hyperpigmentation which is present in approximately 15% of newborns (especially dark-skinned males), affects the center and lower abdomen (blackness line), the area around the areolas, the axillae, the periungual region, and the genital surface area (the scrotum in males and the labia and vulva in females), and has been associated by some authors with stimulation in utero by MSH.i,ix

In summary, we have presented a new case of transient pigmentary lines in the skin folds of the abdomen in a white babe; this entity has been rarely described in reports or in medical journals and is possibly underdiagnosed, but familiarity with this condition is primal for routine dermatologic do.
