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 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 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 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.

Perforating lichen nitidus is an unusual variant of lichen nitidus. It is clinically characterized by umbilicated papules and histopathologically characterized by transepidermal elimination of inflammatory debris from granulomatous infiltrates. Most cases of perforating lichen nitidus are treated with topical corticosteroids, but long-term use of topical corticosteroids could provoke several side effects. Herein, we report a case of perforating lichen nitidus treated effectively and safely with topical tacalcitol ointment. We performed a dermoscopic examination for the perforating lichen nitidus lesion and found the characteristic "frogspawn" dermoscopic feature.
