Cimicosis is a highly itchy,
cutaneous response to the bites of Cimex lectularius, a
bedbug that can feed on human blood once a week at nighttime. Usual
clinical signs of the skin reaction to the saliva are linear groups
of pruritic swelling with a central hemorrhagic point. Depending on
the location of the bite, small blisters can develop as well (e.g.,
on eyelids). The efflorescence usually remains for several days and
up to 2 weeks. At first, groups of solitary papules are noted,
which later tend to fuse together. The predilection sites are
uncovered body parts...
