Line-field confocal optical coherence tomography of xanthogranuloma: Correlation with vertical and horizontal histopathology.

Line-field confocal optical coherence tomography (LC-OCT) is a new noninvasive technique for a real-time, vertical, and horizontal imaging of the skin at cellular resolution. A 47-year-old female presented with a 6-month history of an asymptomatic yellowish papule. LC-OCT evaluation was able to show the diagnostic microscopic features of xanthogranuloma and showed an excellent correlation with vertical and horizontal histopathological sections by revealing enlarged dermal papillae containing multiple, bright roundish giant cells, corresponding to foamy histiocytes, and giant cells characterized by a dark center surrounded by a highly hyper-refractile peripheral ring, corresponding to Touton cells.

A novel treatment of diaper dermatitis in children and adults.

Background: Diaper dermatitis (DD) is an acute inflammatory reaction, regardless of the cause, of the diaper-covered area. Topical skin barrier repair cosmetic products are the mainstay treatment to cure and/or prevent DD.

Aims: To assess the efficacy/tolerability of a zinc gluconate-taurine/zinc oxide and panthenol/ glycerin/ Butyrospermum parkii butter barrier cream using clinical evaluation.

Clinical evidences of urea at low concentration.

Urea is a hygroscopic molecule that, because of its moisturising properties, is topically used for the treatment of skin dryness at concentrations ranging from 2% to 12% in different formulations. Based on existing literature, low-concentration urea-containing products are effective in the treatment and/or prevention of xerosis in some skin disorders such as ichthyosis, atopic dermatitis and psoriasis, or unrelated to specific skin diseases. Generally, urea formulations at low concentration are well-tolerated and suited for the treatment of large skin areas, once or twice daily, even for a long period of time.
