A 9-year-old girl newly diagnosed with systemic lupus erythematosus (S
LE) developed a localized linear papulovesicular eruption over the rig
ht dorsal hand and ulnar forearm. The skin findings were clinically su
ggestive of herpes tester, lichen striatus, or lichen planus-lupus ery
thematosus overlap. However, histologic, immunofluorescent, immunoelec
tron microscopic, and immunoblot studies revealed findings compatible
with bullous SLE. Our patient is noteworthy because she is the first o
ne reported with bullous SLE presenting in a localized linear pattern.
She is also the second-youngest reported patient with bullous SLE.
