A 32-year-old Filipino male managed as a case of acute myeloid leukemia presented with a 6-month history of generalized, red-brown papules. After chemotherapy, the patient was advised 30-minutes daily sun exposure as a form of natural phototherapy. On follow-up, most lesions flattened. This case demonstrates chemotherapy’s potential role in controlling the patient’s inflammatory state and using ultraviolet light therapy in the form of sunlight to manage generalized purpuric lichen nitidus.

Lichen nitidus (LN) is an uncommon, usually asymptomatic cutaneous eruption characterized by the presence of multiple, small, flesh-colored papules. The epidemiologic and pathophysiologic characteristics of LN have not yet been defined. Furthermore, LN has rarely been described in association with other cutaneous diseases. We herein report 3 cases of LN associated with various cutaneous diseases, including lichen striatus, oral lichen planus, and psoriasis vulgaris.

Lichen nitidus is an uncommon, asymptomatic cutaneous shiny papular eruption and it can rarely show Koebner's phenomenon, which may clinically resemble lichen striatus. It is known that for such cases, the clinicopathological correlation is the most important factor for making the diagnosis and immunohistochemical staining for CD4, CD8 and CD68 can be helpful to differentiate these two diseases. We experienced a case of Koebner phenomenon, which clinically mimicked lichen striatus, in a patient suffering with lichen nitidus.

Lichen nitidus is an uncommon chronic inflammatory disease characterized by multiple minute discrete flesh-colored dome shaped papules. Its distribution is frequently localized on trunk, arm or penis. There are a few cases reported to occur on palm and sole. We report a case of lichen nitidus which presents erythematous or brownish colored hyperkeratotic plaques, composed of 1-2 mm sized small papules on the right palm. Its hitopathologic findings were consistent with a diagnosis of lichen nitidus.

Lichen planus is an unique, common inflammatory disorder that affects the skin, mucous membranes, nails and hair. Oral lichen planus is among the more common mucosal conditions with an unknown etiology. Lichen nitidus is an uncommon, usually asymptomatic cutaneous eruption that is characterized by the presence of multiple, small, flesh colored papules. Perforation in lichen nitidus is a rare phenomenon. Lichen nitidus is distinguished from lichen planus on both clinical and histologic grounds. However, the possibility that lichen nitidus represents a micropapular variant of lichen planus has never been definitively excluded. Herein, we report on a case of perforating lichen nitidus associated with oral lichen planus.

Lichen striatus is an uncommon dermatosis that generally affects children. Lichen striatus can usually be identified by the typical clinical and histological features. However, sometimes a differential diagnosis of lichen nitidus is difficult to determine because the clinical manifestations and histologic findings are so diverse. In such cases, immunohistochemical staining can be helpful to differentiate these two diseases. We experienced two cases of lichen striatus which mimicked lichen nitidus clinically and histologically, but were finally diagnosed by immunohistochemical staining.

Lichen nitidus is an uncommon chronic dermatosis characterized by its typical clinical and histopathologic findings and has rarely been described in association with other diseases. We observed a patient with an association of lichen nitidus and molluscum contagiosum, which to the best of our knowledge has not been previously reported in the literature. It remains to be further studied about a possible pathogenesis of lichen nitidus secondary to some viral infections such as molluscum contagiosum, etc.
