Lichen sclerosus of the lip.

Lichen sclerosus is a chronic inflammatory mucocutaneous disorder predominately affecting prepubertal girls and postmenopausal women. Isolated lichen sclerosus affecting the oral mucosa is exceedingly rare. Only 13 patients with biopsy-proved isolated oral disease have been reported in the literature.

A novel GJA 1 mutation in oculo-dento-digital dysplasia with curly hair and hyperkeratosis.

Oculo-dento-digital dysplasia (ODDD) is a rare autosomal dominant congenital disorder mainly affecting the development of the face, eyes, skeletal system, heart and dentition. ODDD has been mapped to chromosome 6q22-q24 and germline mutations have been identified in the connexin 43 gene, GJA1. Abnormalities of the skin, hair, and nails have been recognized in ODDD but are often easily overlooked.

Prevention of nosocomial infection during dermoscopy?

Background: Dermatoscopes are applied directly to cutaneous or mucocutaneous surfaces with immersion fluid (IF) such as oil or alcohol to reduce light reflection. Recently, Staphylococcus aureus has been isolated from dermatosopes that used mineral oil as the IF. Thus, dermatoscopes might be a potential source of nosocomial infection.

Isolated lichen planus of the lower lip.

An idiopathic inflammatory dermatosis, lichen planus (LP) involves the skin, mucosa, or both, in a variety of clinical forms. The involvement of the mucous membranes is seen frequently and usually is asymptomatic, but occasionally, LP can be complicated by extensive painful erosions. We report the case of a 44-year-old man who presented with a 3-year history of isolated lower lip erosions, for which the diagnosis of LP was made.
