Question: Dark Streaks


 BuzyBeeTree123 - Fri Jun 18, 2010 5:00 pm

After discovering two dark colored streaks on my outter thigh, I made an appt. with my dermatologist. The streaks have not faded or grown in a month. She believed it was caused by citrus (of some sort) that I got on myself while in the sun for an extended amount of time (we eat lots of limes, lemons & are ALWAYS in the sun). It does seem the streaks are the exact shape of my fingers. Does this sound like a reasonable situation/diagnosis?

User avatar Hello,Your dermatologist is absolutely right.What we are looking at here is known as Berloque dermatitis or phytophotodermatitis which are synonyms.
Citrus fruirs,perfumes etc contain substances which make our skin sensitive to sunlight.This isknown as phototoxic reaction.
These resemble fingerprints or linear like finger and the burises heal to leave behind blak or brown pigmentation.
These if occur in children may be mistaken by the doctor as child abuse since sometimes two or three finger marks are identified.
These heal in time and may not need intervention.Acute stages may need application of soothening lotions like calamine.
Best wishes.
