The diverse effects may be due to complex underlying mechanisms of action associated with tretinoin, including keratolytic activity, collagenesis, and other mechanisms associated with the activation of nuclear retinoic acid receptors (RARÎ±, RARÎ², and RARÎ³).

Like other epidermal naevi, comedo naevus is rarely associated with other abnormalities of the cell of origin, the embryonic ectoderm. Nevus Comedonicus: Introduction. Nevus comedonicus (NC), first described by Kofmann in 1895, is a rare condition considered to be a type of epidermal nevus. Volunteer sample of 11 adults, 51 to 76 years old, with clinically evident photodamage of the forearms. Objective: Clinical assessment scores were determined at each treatment session and follow-up visit. The nonablative 1450 nm diode laser may be effective in achieving mild to moderate gradual clinical improvement in the treatment of facial atrophic acne scars. Patient satisfaction scores and in vivo microtopography measurements paralleled the photographic and histopathologic changes seen. Abstract. Although the nevus comedonicus is viewed by many as a hamartoma arising from a defective mesoderm, others consider this lesion to be an epidermal nevus involving the hair follicle or an appendageal nevus of sweat ducts. Methods: Numerous therapies have been reported in the literature, including surgical excision, dermabrasion, manual extraction of keratin, application of ammonium lactate lotion, application of topical retinoic acid or keratolytic agents, and oral isotretinoin. Conclusion: Orf is a viral zoonotic skin disorder which is also called ecthyma contagiosum.
