This unfortunate patient was misdiagnosed as having poison ivy. Turns out it was a bedbug infestation. Hints to the diagnosis include:
*Potential exposure to bedbugs (recent travel, new apartment inside a building with known bedbug infestation)
*Itchy red skin spots that may have a little vesicle and scab over
*Skin spots may fade and new ones appear upon waking in the morning (from the bedbugs feeding again at night)
*Skin spot may be in a linear arrangement (from one bug drilling for capillaries in a row)
*Partner or others in the home with similar symptoms.
