Another study has recently concluded what I wrote in my 2007 book
that a skin biopsy should be done to determine demodex density to
rule out Demodectic Rosacea. Here is the conclusion:

"Demodicosis should be considered in the differential diagnosis of
recurrent or recalcitrant rosacea-like, granulomatous rosacea-like,
and perioral dermatitis-like eruptions of the face. Potassium hydroxide
examination, standardized skin surface biopsy, skin biopsy, or a combination
of these are essential to establish the diagnosis."
