“…In 2006, we described an outbreak of an unusual dermatitis associated with a specifi c clinical sign that we called the comet sign (1). In 2007, similar cases occurred and we demonstrated that the mite P. ventricosus was the causative agent of the condition.…”

“…dermatitis has been described as a pruritic erythematous rash with maculopapules with a central microvesicle (7). We initially reported that the typical pruritic erythematous macules were sometimes associated with a linear tract (comet sign) (1).
