Uncommon variants of fixed drug eruption

“…Linear fixed drug eruption: As the name suggests, in this unique variant of fixed drug eruption, lesions appear along a linear distribution. [24][25][26] The linearity could be attributed to a dermatomal distribution, along lines of Blaschko, skin tension lines, or due to Wolf's isotopic response after either herpes zoster, insect bites, or cellulitis.…”

Linear fixed drug eruptions to Levofloxacin

“…Very few cases of FDE with linear distribution have been reported so far. [ 2 3 4 5 ] The drugs incriminated in linear FDE include azithromycin,[ 2 ] levofloxacin,[ 3 ] carbamazepine[ 4 ] and ciprofloxacin. [ 5 ]…”
