Generalized lichen nitidus with involvement of the palms following interferon alpha treatment. Dermatology. 2007;215(3):236-9.

Lichen nitidus is an uncommon dermatosis of unknown etiology. Here we present the case of a generalized lichen nitidus with involvement of the palms in a patient with hepatitis C after systemic treatment with interferon alpha and ribavirin. Furthermore in our patient we could show a strong lesional expression of MxA, a protein specifically induced by type I interferon. It is tempting to speculate that interferon alpha may be involved in the pathogenesis of lichen nitidus.

Generalized purpuric lichen nitidus. Report of a case and review of the literature.Dermatol Online J. 2007 May 1;13(2):5.

Generalized purpuric lichen nitidus is an extremely rare form of lichen nitidus. We present the third documented case of this uncommon dermatosis, which was treated successfully with orally administered cyclosporine. During a 12-month follow-up after the cessation of the drug, no recurrence was noticed.

Generalized lichen nitidus successfully treated with narrow-band UVB phototherapy: two cases report.J Korean Med Sci. 2007 Feb;22(1):163-6.

Lichen nitidus (LN) is an uncommon chronic inflammatory skin disease composed of numerous, tiny, shiny, flesh-colored papules that are predominantly observed on the chest, abdomen, glans penis and upper extremities. The distribution of LN is most often localized, but in some cases it can become generalized. Because LN tends to be asymptomatic and presents spontaneous resolution within several years, it usually does not require treatment except in symptomatic, persistent and generalized cases. We describe a 28-yr-old man and a 7-yr-old boy with generalized LN where both cases improved with narrow-band ultraviolet B (NB-UVB) phototherapy plus topical steroid ointment. Both patients noted improvement within the first three treatments and showed almost complete resolution after 18 and 20 treatments, respectively. NB-UVB phototherapy may be an effective alternative therapy for the treatment of generalized LN, even for those patients in their childhood.
