“…We report herein the case of an infant with an unusual pattern form of hyperpigmentation that was thought to be due to the pattern of fetal posture in utero typically following skin creases (2). A review of the literature search reveals only six such cases (1–4).…”

“…In 1993, Halper et al [13] documented three infants with pigmentary lines of the newborn. In the first case, a 6-week-old black boy showed hyperpigmented lines bilaterally on the extensor surfaces of his arms, legs, hands, feet, back and flanks.…”

Various diseases of pigmentation in the newborn are known, such as congenital or acquired linear hyperpigmentation. Pigmentary lines of the newborn are counted among the transient benign cutaneous lesions in the newborn and appear to be rather rare. This paper reports on a newborn with pigmentary lines in the creases of the abdomen. The 5-month-old boy is the first case observed so far in the University Hospital of Basel in Switzerland. He was born at term and healthy, without any congenital abnormalities. The horizontally arranged linear hyperpigmentation appeared shortly after birth and faded spontaneously after 5 months. Pigmentary lines of the newborn are rare and the non-hormonal cause may be flexion in utero or other mechanically induced stimulation. So far, only eight similar cases have been reported, which are listed in a table.

“…Although the mechanisms responsible for this kind of darkening are unclear, it has been postulated that it could be a result of MSH stimulation in utero (1). Less frequently, other types of hyperpigmentation not related to hormonal stimulation have also been reported, including an extremely rare pigmentary phenomenon consisting of transient horizontal bands on the creases in the abdomen or in the back (1–3). These linear hyperpigmented bands are thought to be a result of mechanical trauma from hyperkeratosis within the folds, probably because of flexion in utero that provokes a postinflammatory hyperpigmentation (1,2).…”

Different patterns of transient cutaneous pigmentation have been reported in otherwise healthy newborns. Frequently, in darkly pigmented neonates, skin hyperpigmentation can be observed in some areas such as genitals, lower abdomen, or at the base of the fingernails. Although the mechanisms responsible for this kind of darkening are unclear, it has been postulated that it could be a result of MSH stimulation in utero (1). Less frequently, other types of hyperpigmentation not related to hormonal stimulation have also been reported, including an extremely rare pigmentary phenomenon consisting of transient horizontal bands on the creases in the abdomen or in the back (1-3). These linear hyperpigmented bands are thought to be a result of mechanical trauma from hyperkeratosis within the folds, probably because of flexion in utero that provokes a postinflammatory hyperpigmentation (1,2). This variant of pigmentation has been described in black, male infants, and it disappears normally without treatment by 6 months of age. We have recently observed a caucasian female newborn with transient pigmentary bands on her abdomen and back.A 2-week-old female infant was referred for evaluation of a pigmentary abnormality present since birth. She was born at term by cesarean section. No family history of similar markings was found. Examination revealed extensive linear pigmentation on the trunk, with multiple brown-grayish parallel transversal lines bilaterally located on the abdomen and back. In addition, she had a wide vertical area of hyperpigmentation all over her spine, and several hyperpigmented macules scattered over her back (Fig. 1). The child was in good health and there was no sign of any underlying abnormality. Her face, extremities, and mucosae were spared, and her nails and hair were normal. Thus, the girl was followed up and a skin biopsy was not performed.During the following 6 months, the bands underwent spontaneous resolution, its color matching the surrounding skin. REFERENCES1.
