AbstractBackgroundCradle cap is a benign and self‐limiting variant of seborrheic dermatitis (SD) that can be distressing for parents.AimsTo assess by clinical/laboratory/instrumental evaluation the efficacy/tolerability of a gel cream containing piroctone olamine (antifungal), biosaccharide gum‐2 (antifungal), stearyl glycyrrhetinate (anti‐inflammatory), and zinc l‐pyrrolidone carboxylate (zinc‐PCA) (antiseborrheic) in the treatment of mild/ moderate cradle cap.MethodsIn this prospective, open‐label trial, 10 infants, with mild/moderate cradle cap enrolled at the Dermatology University Clinic of Catania (Italy) used the tested gel cream twice daily for 30 days. Degree of erythema was evaluated clinically by a 5‐point severity scale (from 0=no erythema to 4=severe erythema), at baseline, at 15 and 30 days. Desquamation was rated by dermoscopy evaluation using a 5‐point scale (from 0=no desquamation to 4=severe/many large adherent white flakes), at all time points. An Investigator Global Assessment (IGA) using a 6‐point scale (from −1=worsening to 4=complete response/clear) was also performed at 30 days. Five subjects, randomly selected, underwent double microbiological evaluation for bacteria and yeasts by cultures of cotton swabs at baseline and at 30 days. Tolerability/acceptability was evaluated on a 4‐point scale (from 0=very poor to 3=excellent) at 15 and 30 days. Data were processed using SAS version 9.ResultsAt baseline, a significant colony‐forming unit (CFU) count for Malassezia furfur and Staphylococcus aureus was detected in 4 out of 5 selected patients. After 15 and 30 days, a statically significant reduction from baseline in erythema and desquamation severity was observed, along with a reduction in CFU count for Malassezia furfur and Staphylococcus aureus from baseline. No signs of local side effects were documented.ConclusionsOur results indicate that the tested gel cream may represent a valid option to treat mild‐to‐moderate forms of cradle cap and support its antifungal and antibacterial properties.

AbstractBalloon cell nevus (BCN) is a histopathological variant of cutaneous acquired melanocytic nevi characterized by junctional and/or dermal nests of large cells with a clear and foamy cytoplasm which has rarely been described in children. Three cases of BCN firstly reported on the scalp in two pediatric patients are presented along with a literature review. Dermoscopy is particularly indicated in those pigmented lesions showing a yellowish hue, in ruling out in real time those disorders that may clinically be similar such as xanthogranuloma and sebaceous nevus, and to suggest the diagnosis of BCN. The final diagnosis, however, is established by histopathological examination.
