[size=4][color=#000000][font=Arial, sans-serif]I think this is rosacea. An infundibulofollicular unit was destroyed by the inflammatory process, thereby its [/font][/color][/size][color=#000000][font=Arial, sans-serif]released [/font][/color][color=#000000][font=Arial, sans-serif]contents, including Demodex mites, have ensued a peri-infundibular foreign body granuloma against fragments of infundibular epithelium, keratin, sebaceous gland secretion, and Demodex mites.[/font][/color]
[size=4][color=#000000][font=Arial, sans-serif]I believe Demodex are no more than non-pathogenic commensals that can be found incidentally in any infundibulum lesions, and they are not the cause of those lesions, even less of the so-called demodicosis.[/font][/color][/size]

I confess I was hoping for a bit more discussion of granulomatous rosacea v's demodecosis in this case. Does everyone agree demodex is incidental? I am inclined to think it may be worth treating some patients. I remember one case where I really did feel histologically the demodex was relevent and the patient was treated with ivermectin. It was a localised patch on the face I think and it became very red and angry after ivermectin. This case was clinically ?dermatitis ?rosacea.
