Pediatric Lichen Sclerosus: A Review of the Epidemiology and Treatment Options.

Lichen sclerosus (LS) is a rare, chronic, inflammatory disease of the skin that primarily affects postmenopausal women but may occur in men and children as well. Approximately 7% to 15% of cases are believed to occur in children. The epidemiologic data for LS have been limited and treatment options are not well studied, particularly in children.

Cutaneous leishmaniasis in Cuban immigrants to Texas who traveled through the Darién Jungle, Panama.

Cutaneous leishmaniasis is rarely seen in the United States. Four Cuban immigrants traveled along the same route at different times from Cuba to Ecuador, then northward, including through the Darién Jungle in Panama. These patients had chronic ulcerative non-healing skin lesions and were given a diagnosis of leishmaniasis.

Periungual Bowen's disease in a 4-year-old girl.

Bowen's disease (BD), or cutaneous squamous cell carcinoma (SCC) in situ, is rare in children. BD usually occurs in Caucasian adults on sun-exposed areas and may progress to invasive cutaneous SCC. Most cases of periungual BD have been linked to human papillomavirus infection.

Atopic keratoconjunctivitis: A review.

Atopic keratoconjunctivitis is a chronic noninfectious inflammatory condition and is one of the most severe ophthalmic complications associated with atopic dermatitis. It requires prompt and effective treatment to prevent permanent vision loss. Complications of atopic keratoconjunctivitis include cataracts, keratoconus, infectious keratitis, blepharitis, tear dysfunction, and steroid-induced glaucoma.

Granuloma annulare mimicking multicentric reticulohistiocytosis.

We describe a patient with granuloma annulare (GA) who presented with firm periungual papules mimicking "coral beads", a characteristic sign of multicentric reticulohistiocytosis (MRH). We highlight the importance of distinguishing between GA and MRH because the prognoses differ significantly.
