    Demodectic Rosacea is a rosacea variant, just as valid a variant as Granulomatous Rosacea.

    The RRDi is the only non profit organization for rosacea that has officially recognized Demodectic Rosacea as a variant of rosacea. "Recently human primary demodicosis has been recognized as a primary disease sui generis and a clinical classification has been proposed. A secondary form of human demodicosis is mainly associated with systemic or local immunosuppression." [2] This is referring to a paper published in 2014 "to classify human demodicosis into a primary form and a secondary form." [3] While acknowledging the work of Dr. Chen and Dr. Plewig, whether you refer to demodicosis or demodectic rosacea we are referring to the same condition. The term 'demodectic rosacea' was coined by Dr. Plewig in an email to the RRDi on March 2, 2007 where Dr. Plewig wrote, "Concerning your questiones, demodicosis can be a disease by itself and thus being independent of rosacea. Or demodex mites heavily colonize pre-existing rosacea and thus lead to demodectic rosacea ( rosaceiform dermatosis). This is a rather complicated issue. Rosacea is usually diagnosed by inspection [of] the eye. Laboratory tests are rarely needed, for instance in gram-negative rosacea, where one needs bacteriology. The same is true for demodectic rosacea, where one has to demonstrate the mites in great numbers." [4] 

    Current concepts on rosacea is a video presentation by the Charles Institute of Dermatology, University College Dublin with Frank Powell, MD who interviews Fabienne Fortan, MD, Université libre de Bruxelles, Belgium explaining demodectic rosacea:

    Demodetic Rosacea has a long history of controversy which continues to this day. For example, note the following quote:
    "From these and other statements it is seen that in suggesting the thought that these minute forms of life are etiological factors in even some of the phases of acneform diseases, I shall be but little in accord with the highest authorities. In antagonism to these views, I may say that the results of my observations appear to indicate a close relationship of the parasites with the diseased condition."

    • Erbium-doped Yttrium Aluminium Garnet (Er:YAG) Laser Resurfacing Restores Normal Function and Cosmesis in Patients with Severe Rhinophyma. J Clin Aesthet Dermatol. 2019 Jul;12(7):28-33 Authors: Mathis J, Ibrahim SF Abstract Background: Rhinophyma is a dermatologic condition that can lead to severe disfiguration and psychological distress. Many therapies, both medical and surgical, have been reported, but few with acceptable and reproducible cosmesis. Objective: We assessed the efficacy of erbium-doped yttrium aluminium garnet (Er:YAG) laser resurfacing as a treatment modality for rhinophyma of all degrees. Design, Setting, and Participants: Eleven Caucasian male patients were classified into categories of mild, moderate, or severe rhinophyma and were treated at the University of Rochester Medical Center with a dual mode Er:YAG fully ablative laser. Measurements: Severity was graded as mild, moderate, or severe, based on the degree of distortion of normal anatomy. Results: The Er:YAG laser allowed for increased ablative precision, a decreased risk of complications, shorter downtime, and improved outcomes compared to currently available treatments. Conclusion: Our results suggest Er:YAG laser resurfacing is an effective treatment modality, with low risk and excellent, reproducible cosmetic outcomes, for patients with rhinophyma of any severity.

    • Recognizing Rosacea: Tips on Differential Diagnosis J Drugs Dermatol. 2019 Sep 01;18(9):888-894 Authors: Johnson SM, Berg A, Barr C Abstract Rosacea is a common chronic inflammatory dermatosis with a variety of clinical manifestations. Rosacea primarily affects the central face, and includes papules, pustules, erythema, telangiectasias, perilesional redness, phymatous changes, and even ocular involvement. Symptoms may vary among different patients and even vary over time in an individual patient. Central facial redness affects many adults and can be an indicator of the chronic inflammatory disease rosacea. Rosacea is a clinical diagnosis based on the patient’s history, physical examination, and exclusion of other disorders. It is under-diagnosed, particularly in individuals with skin of color. The goal of this article is to provide clinicians with the tools and understanding needed to correctly identify rosacea and differentiate it from other conditions that have overlapping signs and symptoms.
