Acneiform eruptions : a group of disorders that resemble acne vulgaris
![Page 3: Acneiform eruptions in childhood](https://reader033.vdocuments.us/reader033/viewer/2022042708/62667b092a08985e366688dc/html5/thumbnails/3.jpg)
Acne vulgaris
• A chronic inflammatory disorder of the pilosebaceous unit
• It is characterized by comedones,
papules, pustules ,
nodules and/or cysts

Acne vulgaris location
• Face (99% of cases)
• Back (60% of cases)
• Chest (15% cases)

True neonatal acne occurs rarely
![Page 9: Acneiform eruptions in childhood](https://reader033.vdocuments.us/reader033/viewer/2022042708/62667b092a08985e366688dc/html5/thumbnails/9.jpg)
• Acneiform eruptions may affect up to 20% of neonates
![Page 10: Acneiform eruptions in childhood](https://reader033.vdocuments.us/reader033/viewer/2022042708/62667b092a08985e366688dc/html5/thumbnails/10.jpg)
Neonatal acneiform eruptions
• Neonatal cephalic pustulosis
• Acne venenata (use of topical oils and ointments)
• Acneiform eruption due to maternal medication (lithium, phenytoin, steroids)
![Page 11: Acneiform eruptions in childhood](https://reader033.vdocuments.us/reader033/viewer/2022042708/62667b092a08985e366688dc/html5/thumbnails/11.jpg)
Neonatal Cephalic Pustulosis (NCP) • Benign entity
• Sex: ♂
• Location
• Comedones
are absent
• It is often referred as neonatal acne
![Page 12: Acneiform eruptions in childhood](https://reader033.vdocuments.us/reader033/viewer/2022042708/62667b092a08985e366688dc/html5/thumbnails/12.jpg)
NCP: pathogenesis
• NCP: association with skin colonization of the Malassezia species ( M. sympodialis, M. globosa, M. dermatis)
• The exact etiologic role of Malassezia remains unclear as Malassezia is part of the normal flora of neonatal skin
• Lack of complete correlation between NCP and presence of Malassezia species

NCP: pathogenesis cont/ed)
NCP lesions may represent a hypersensitivity reaction to the presence of M. Species in predisposed neonates with more intense sebum production
(Niamba et al. Arch Dermatol 1998; 134:995)

NCP: management
• A self-limited disorder with spontaneous resolution in a few weeks up to 2 months of age
• Reassurance of the parents
• Use of a mild cleanser and water (once or twice daily) If lesions are numerous topical treatment with ketoconazole cream (twice daily, 1 week)

(ESPD 2015; Lausanne Switzerland)
• No of pts:18
• Sex: M:5, F: 13
• Mean age: 5.8yrs
• Studied period: 2008-2014
![Page 27: Acneiform eruptions in childhood](https://reader033.vdocuments.us/reader033/viewer/2022042708/62667b092a08985e366688dc/html5/thumbnails/27.jpg)
Dermatologic and ophthalmologic criteria for
childhood rosacea • Facial flushing with recurrent or permanent erythema
• Facial telangiectasia with no other causative dis.
• Papules and pustules without comedones
• Preferential distribution of lesions on convex areas of the face
• Ocular manifestations (1 of the following)
– Relapsing chalazions
– Ophthalmic hyperemia
– Keratitis
Two criteria are mandatory for diagnosis of childhood rosacea Labreze et al, Arch Dermatol. 2008; 144:167-71

Location: nose (16/18, 89%) Recurrent ocular manifestations (10/18, 55%). The ocular signs preceded the skin manifestations by an average of one year

Pathogenesis of rosacea A dysregulation of the innate immune system
(↑ Cathelicidins, LL-37) ►
• Inflammatory reaction to:
–Cutaneous microorganisms (Demodex species, Bacillus olenorium, Staph. epidermidis )
–Ultraviolet radiation
• Vascular hyper reactivity
• ↑ Mast cells → vasodilatation, angiogenesis
(Cutis 2016; 98:49; J Dermatol Sci 2009; 55:77
Nat Med 2007;13:975 Ital Dermatol Venereol 2009; 144:663)

Pathogenesis of rosacea
• Cathelicidins: antimicrobial peptides
• Antimicrobial peptides: small molecular weight proteins , a part of the innate immune response, Cathelicidins: ↑ levels in patients with rosacea
• LL-37: interacts with endothelial cells → angiogenesis, modulates the expression of VEGF
• Injection of LL-37 into mice induced inflammation, erythema, and telangiectasia (Nat Med 2007;13:975 )

Rosacea- treatment
Treatment of childhood rosacea is similar to that in adult rosacea.

Treatment of childhood rosacea Avoidance of recognized trigger factors
