1. Papular urticaria Papular urticaria is a hypersensitivity disorder in which
insect bites, most often those of fleas, mosquitoes, or
bedbugs, lead to recurrent and sometimes chronic itchy
papules on exposed areas of skin (like the arms, lower
legs, upper back, and scalp). Papular urticaria is reported
predominantly in young children (typically two to 10 years
of age). The diaper areas, genital, perianal, and axillary
areas are spared. The 0.5 to 1 cm lesions may be urticarial
at the start of the syndrome, but become persistent and
papular or nodular with time. The diagnosis of papular
urticaria is made clinically, although there may be a delay
between the inciting bite and the onset of lesions, or insect
bites may not have been noticed at all. Usually only one
child in a family is affected, a clue that infestation at home
is unlikely. New lesions may appear sporadically, and re-
newed itching may lead to reactivation of older lesions,
leading to a chronic and cycling disorder that may last
from months to years. Management of papular urticaria
includes selective and limited use of non-sedating antihis-
tamines for pruritus, mid-potency topical corticosteroids
applied to individual lesions, and reassurance, as the dis-
order eventually resolves spontaneously.

cause of itchy bumps on her
legs. Yesterday, there were a few
bumps on the girl's legs, which
she has been constantly scratch-
ing. She did recall that she had
insect bites on her legs a month
ago when she went hiking with
, her brother and father although
she has not had any insect bite
recently. On skin examination,
there are multiple 0.5 cm to 1 cm
papules with central crusts and
excoriations on both her legs.

,7. Rust Ring Metallic foreign bodies embedded in the cornea develop
rust rings due to oxidation of the iron. Rust rings can
develop within hours of metallic foreign body contact with
the cornea. Over 24-48 hours, the rust ring will oxidize and
kill surrounding epithelium. At this time, the rust ring will
be soft and easily removed in one solid plug.
