Abstract: The first report of spinous follicular lichen nitidus with perifollicular granulomas was by Madhok and Winkelmann in 1988. Since this report, a few cases of follicular or periappendageal lichen nitidus have been described, in a more localized form or without perifollicular granulomas. We describe a 5‐year‐old girl with the rare generalized spinous follicular variant of lichen nitidus with perifollicular granulomas.  相似文献

Lichen nitidus of the nail is rare and can precede the onset of skin lesions. Delayed diagnosis is common. We present an unusual case of lichen nitidus–associated nail changes that preceded the onset of skin lesions in a 4‐year‐old Indian girl. We also conduct a review of six other cases of lichen nitidus with nail involvement from the English‐language literature. Clues to the diagnosis of lichen nitidus include violaceous or pigmentary changes of the nail fold and subtle lichenoid papules on the affected digits. Lichen nitidus of the nails appears to be less severe than nail changes of lichen planus and is generally self‐limiting. Understanding the natural history of lichen nitidus of the nails will help physicians better counsel patients and their families.  相似文献

A 27-year-old man was seen with multiple, small, shiny papules on his shoulders, upper arms, and trunk, and hyperpigmented violaceous plaques on his feet. The former was diagnosed as generalized lichen nitidus and the latter, as lichen planus. It is not likely that the coexistence of the two diseases in this patient is a fortuitous one, since generalized lichen nitidus is a very rare condition. The association of lichen nitidus and lichen planus suggests that lichen nitidus is closely related to lichen planus and that the two diseases may be different manifestations of essentially the same pathogenetic process.  相似文献

We report a 38-year-old man who presented with a generalized papular eruption that was clinically and histologically consistent with lichen nitidus. This patient's condition had been persistent for approximately 1 year; however, soon after assuming employment that entailed significant, regular sun exposure, the patient noted marked clearing of his lesions in sun-exposed areas. This case corroborates previous reports that suggest that generalized lichen nitidus can be successfully managed with ultraviolet light therapy.  相似文献

BACKGROUND: Generalized haemorrhagic lichen nitidus is rare. To our knowledge, this form of presentation has only been reported once. OBJECTIVE: To describe a new case of generalized haemorrhagic lichen nitidus simulating a pigmented purpuric dermatosis. METHODS AND RESULTS: We document a 24-year-old man who presented with an 8-month history of a progressive non-pruritic, red-brown papular eruption on the dorsa of the feet, ankles and distal third of the legs. A diagnosis of Schamberg's progressive pigmentary dermatosis was made, and no treatment was prescribed. Two months later, the lesions had extended to the abdomen, groins, forearms, elbows and wrists. Biopsy of the skin of the right foot revealed lesions typical of lichen nitidus with subepidermal extravasation of red cells and capillary wall hyalinization. Macrophages and T lymphocytes were abundant in the infiltrate. CONCLUSION: Purpuric generalized lichen nitidus should be included in the differential diagnosis of pigmented purpuric dermatoses.  相似文献

Lichen nitidus is a rare condition of unknown cause, characterized by minute, flesh-colored, shiny papules occurring on the genitalia, abdomen, chest, and extremities. This disorder is most often localized, but a few cases of generalized lichen nitidus have been reported. We describe a young patient with a 1.5-year history of unremitting generalized lichen nitidus.  相似文献

Several unusual variants of lichen nitidus are described in the literature. Spinous follicular lichen nitidus with perifollicular granulomas is one such variant characterized by generalized follicular as well as nonfollicular keratotic papules, which show perifollicular granulomas on histopathology as well as a lichenoid granulomatous tissue reaction typical of lichen nitidus. Owing to its atypical clinical and histopathologic manifestations, it raises several clinical possibilities and can be a diagnostic challenge. We report this rare variant of lichen nitidus in a 19-year-old female, and discuss its clinical and histopathological differential diagnosis.  相似文献

A case is presented of lichen nitidus that evolved into an acquired palmar keratoderma in a fifty year old woman; this is a rare manifestation of the disease. Lichen nitidus must be considered in the differential diagnosis of keratoderma palmaris.  相似文献

Lichen nitidus is a disease of unknown etiology, characterized by flesh-colored, shiny papules of 1-2 mm and generally asymptomatic or with mild pruritus. The most common sites of occurrence are genitalia, upper limbs, trunk and abdomen. The generalized form is rare. This is the fourth reported case of lichen nitidus associated with Down Syndrome.  相似文献

Lichen nitidus is an uncommon lichenoid dermatosis that could be defined as multiple, separated, shiny, pinpoint, pale to skin-colored papules. Palmoplantar lichen nitidus is a quite rare variant of lichen nitidus. It is hard to make a diagnosis of palmar lichen nitidus when there are no lesions elsewhere on the body. There are some dermoscopic features defined for both palmoplantar and non-palmoplantar lichen nitidus that might be useful to facilitate the diagnosis before histopathological examination. Herein, we report a case of a 24-year-old man diagnosed with isolated palmar lichen nitidus with dermoscopic features and histopathological confirmation.  相似文献

Generalized lichen nitidus is an uncommon chronic inflammatory dermatosis with very characteristic histological findings. Its pathogenesis is still unclear; very rarely it has been associated with genetic disorders. Herein we report the case of a 12-year-old boy with Niemann-Pick disease who developed generalized lichen nitidus.  相似文献

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.  相似文献

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.  相似文献

BACKGROUND: The histology of lichen nitidus has been described previously but a follicular variant has not been emphasized. METHOD: We report a case of lichen nitidus with periappendageal inflammation resulting in histologic similarities to lichen striatus. RESULTS: This case extends the spectrum of histologic findings in lichen nitidus and shows overlap in the distribution of the inflammatory infiltrate in lichen nitidus and lichen striatus.  相似文献

BACKGROUND: Lichen nitidus is a rare condition, which may be a cause of palmoplantar hyperkeratosis. We report two cases. CASE REPORTS: A 53 year-old woman presented with a dry and fissured palmoplantar hyperkeratosis. Histological examination of a biopsy showed the typical features of lichen nitidus. Significant improvement was obtained with acitretin. A few months later, multiple lichen nitidus papules appeared on the limbs and the abdomen. A 67 year-old woman was referred to us for a fissured, disabling palmoplantar hyperkeratosis refractory to topical steroids. Histological examination led to the diagnosis of lichen nitidus. Local PUVA therapy resulted in the cleaning of her lesions. Later, typical papules of lichen nitidus appeared on her elbows. DISCUSSION: Nineteen cases of palmoplantar localization of lichen nitidus have been described. The features are usually tiny yellow papules but sometimes a non-specific keratoderma resembling chronic eczema. Palmoplantar involvement of lichen nitidus may be isolated or associated with cutaneous lesions on unusual sites. Oral retinoids and local PUVA are effective treatments.  相似文献

BACKGROUND: Narrow-band ultraviolet (UV) phototherapy has not been used in the treatment of lichen nitidus. AIM: To report two cases of generalized lichen nitidus successfully treated with narrow-band UV-B phototherapy. METHODS: A 7-year-old girl presented with a persisting, asymptomatic, papular eruption refractory to topical steroid for 3 months. Another 10-year-old boy presented with an asymptomatic papular eruption present for 6 months. The histopathologies of both lesions were consistent with lichen nitidus. The lesions were treated with narrow-band UV-B phototherapy. RESULTS: The lesions of the patients were almost completely cleared after the 30th and the 17th irradiation, respectively. CONCLUSIONS: Narrow-band UV-B may be an effective alternative therapy for the treatment of generalized lichen nitidus unresponsive to common therapies.  相似文献

Lichen nitidus is a rare chronic condition of unknown etiology. Generalized lichen nitidus is even rarer. We report here a 5-year-old girl who had multiple, asymptomatic, discrete, 1 to 2 mm flesh-colored, shiny, flat, papules on her face, upper limbs, and thighs with relative sparing of the trunk. Resolution of these papular lesions was followed by hyperpigmented macules in those areas. Histopathologic examination of a papular lesion revealed a localized granulomatous lymphohistiocytic infiltrate in an expanded dermal papilla with thinning of overlying epidermis and downward extension of the rete ridges at the lateral margin of the infiltrate, producing a typical "claw clutching a ball" picture, confirming our clinical diagnosis of lichen nitidus. The pigmented macules showed melanin pigmentation on histology. There was no response to oral astemizole treatment for 3 months. However, the lichen nitidus lesions resolved spontaneously without any further treatment over the next year, leaving behind a prominent pigmentary disturbance.  相似文献

Two patients, one man aged 65 and one woman aged 48, presenting generalized lichen nitidus are reported. The clinical and histopathologic features of this uncommon presentation of lichen nitidus are illustrated as well as the excellent clinical response to the treatment with an H1-blocking antihistaminic (astemizol).  相似文献
