Transient Pigmentary and Demarcation Lines in a Newborn: A Case Report

“…The hyperpigmented lines seen on this infant at 7 weeks of age were innumerable on the abdomen, dorsal foot, and ankle, in contrast with most previous case reports, which describe 4-10 lines across the abdomen [1][2][3][4][5][6][7][8][9]. Multiple factors may have contributed to the noted severity in our patient, including young age at presentation and Fitzpatrick skin type.…”

“…The differing pigment zones between the chest and abdomen in this case may reflect the border between developmental segments. In the European dermatology literature, it has been proposed that TPLN are caused by abnormal melanocyte migration [7,8]. We hypothesize that TPLN is caused by immature melanocyte activity and a genetic predisposition to TPLN and pigmentary demarcation lines.…”

“…We hypothesize that TPLN is caused by immature melanocyte activity and a genetic predisposition to TPLN and pigmentary demarcation lines. Further, the father of a TPLN patient of Senegalese descent was aware of multiple family members with a similar history, supporting a possible genetic component [7]. Changes in skin maturation over the first 2 years of life are already accepted as factors in the evolution of skin findings such as tardive congenital melanocytic nevi, pigmentary mosaicism, and pigmentary demarcation lines [9].…”

Horizontal lines in a 4‐month‐old infant

“…The first case of pigmentary lines of the newborn was described in 1967 in a Black male infant 1 . Since then, few reports have been published in the literature, suggesting the rarity and benign nature of the condition 2–8 . Although one familial case has been reported, 3 the dermatosis is usually sporadic.…”

Pigmentary Lines of the Newborn: A Case Report and Review of the Literature

“…Prigent et al [14] reported a hyperpigmentation in a Senegalese black, male newborn in the year 2000. The pigmentation was located on the flexural lines of the extremities.…”
