Lichen striatus in a pregnant woman

Abstract

We report a case of lichen striatus in a 37-year-old woman in the third trimester of pregnancy. She presented at 35 weeks of pregnancy with a 6-week history of a pruritic rash on the left side of her abdomen. Examination revealed an erythematous papular eruption arranged in a linear fashion from the umbilicus to the left mid back. Histological examination demonstrated lichenoid perivascular and periadnexal inflammatory infiltrate and the presence of colloid bodies. The eruption resolved prior to delivery with the application of mometasone furoate 0.1% ointment.

“Pediatric Blaschkitis”: Expanding the Spectrum of Childhood Acquired Blaschko‐linear Dermatoses

“…A tendency for different types and distributions of inflammation in LS and blaschkitis may be related to variability in the triggers and background immunologic state as well as the abnormal clone itself. Viral infections, vaccinations (e.g., hepatitis B and BCG), pregnancy, and trauma have been reported as possible precipitants of LS (5,7,(33)(34)(35)(41)(42)(43)(44); in addition to viral infections, medications (e.g. metronidazole) and emotional stress have been implicated in blaschkitis (18,24,25).…”

Bilateral lichen striatus: A case report with review of literature

“…[6] Atopy has been reported to be a predisposing factor. Drugs, such as adalimumab and etanercept, BCG and hepatitis B vaccination, UV exposure from a tanning bed, minor trauma, insect bite, and viral infections, such as varicella, influenza, and human herpes viruses 6 and 7 have been reported as triggers.…”

Pediatric Dermatology Photoquiz: Persistent Lesion of the Thumbnail of a 3‐Year‐Old Boy

“…The precise etiology of lichen striatus is unknown, although a combination of genetic factors (e.g., predisposition to atopy or other autoimmune conditions) and environmental factors (e.g., preceding viral infection, pregnancy) have been theorized to contribute to its development . The natural history of lichen striatus is generally such that resolution occurs over several months.…”
