Koebner Phenomenon in Lichen Nitidus

Lichenoid eruptions in children

“…53,54 As in LP, the Koebner phenomenon is observed. 55 In fact, the Koebner phenomenon is present almost 100% of the time and is a hallmark for this disorder (Fig 3). Intraoral lesions in the form of minute grayish flat papules on the buccal mucosa have been described.…”

Summertime Actinic Lichenoid Eruption

“…Clinically similar lesions of lichen nitidus [6] are usually asymptomatic, discrete, not confined to sun-exposed areas and do not show any seasonal variation. Classical lichen planus papules are larger, polygonal, flat topped and violaceous and its actinic variant is mostly characterized by dyschromie or pigmented plaques with crenated margins [1], Micropapules similar to those seen in SALE or lichen nitidus are, however, sometimes seen as satellites to larger typical lesions of lichen planus or lichen planus actinicus but microscopically these demonstrate a characteristic lichenoid tissue reac tion ( fig.…”

Treatment of generalized lichen nitidus with narrowband ultraviolet B

“…1 None of the current available therapies is curative and this subjects the patient to multiple repeated and protracted treatment cycles with attendant acute and longterm toxicity. 2 Because lymphomatoid papulosis responds to systemic interferon alfa-2a with a 5-month remission 3 and because mycosis fungoides (a related lymphoproliferative disease) responds to topical imiquimod 5% cream (an inducer of local interferon production), 4 it seems reasonable that lymphomatoid papulosis might respond to topical imiquimod cream.…”

“…1 Although spontaneous remissions of LN are common, persistent lesions and those that are refractory to various treatments can pose therapeutic challenges. 2 Sun exposure and psoralen plus ultraviolet A (PUVA) therapy have been reported to be helpful in treating LN.…”
