Exposure to moisture
leads to palmar rash
CAROLINE Y. WINSLOW AND JULIA R. NUNLEY, MD
A 24-year-old woman presented with a six-year history of a recurring,
somewhat painful and pruritic palmar rash. The rash developed on either
hand within minutes of exposure to water or sweating and disappeared
after about an hour of drying. She arrived at the ofﬁce with a bucket
of water in which to submerge her hand to demonstrate the problem.
Her medical history was otherwise unremarkable. Physical exam of
the sodden hand revealed conﬂuent, edematous, hypopigmented-to-
translucent papules with visibly prominent ductal openings.

with edema over the distal ﬁnger pads of all 10 digits. Intense ery-
thema, edema, and palpable warmth were observed on all 10 distal
toe pads. Tactile sensations were intact.
