Laugier-Hunziker syndrome associated with actinic lichen planus

Mystery behind labial and oral melanotic macules: Clinical, dermoscopic and pathological aspects of Laugier-Hunziker syndrome

Labial and oral melanotic macules are commonly encountered in a broad range of conditions ranging from physiologic pigmentation to a sign of an underlying life-threatening disease. Although Laugier-Hunziker syndrome (LHS) shares some features of labial and oral pigmentation with a variety of conditions, it is a benign and acquired condition, frequently associated with longitudinal melanonychia. Herein, the demographic, clinical, dermoscopic, and pathological aspects of LHS were reviewed comprehensively. The important differential diagnoses of mucocutaneous and nail pigmentation are provided. An accurate diagnosis is crucial to design a reasonable medical strategy, including management options, malignant transformation surveillance, and psychological support. It is important that clinicians conduct long-term follow-up and surveillance due to the potential risks of malignant transformation and local severe complications in some conditions.

Laugier-Hunziker syndrome: case report and review of the literature

Laugier-Hunziker syndrome is a rare acquired disorder characterized by diffuse pigmented macules of the oral mucosa. Other mucosal and cutaneous surfaces may be affected, and nail involvement is frequent. A case of Laugier-Hunziker syndrome in a Greek female with multiple buccal and labial mucosal lesions and unusual conjunctival involvement is presented here. In addition, a thorough review of the English language literature of this rather under-recognized syndrome is included and the main differential diagnostic possibilities are discussed.

Laugier-Hunziker syndrome: a report of three cases and literature review

Laugier–Hunziker syndrome (LHS) is an acquired pigmentary condition affecting lips, oral mucosa and acral area, frequently associated with longitudinal melanonychia. There is neither malignant predisposition nor underlying systemic abnormality associated with LHS. Herein, we present three uncommon cases of LHS with possibly new feature of nail pigmentation, which were diagnosed during the past 2 years. We also review the clinical and histological findings, differential diagnosis, and treatment of the syndrome in published literature.

Laugier-Hunziker syndrome

Laugier-Hunziker syndrome is a rare acquired disorder characterized by diffuse hyperpigmentation of the oral mucosa and longitudinal melanonychia in adults. They appear as macular lesions less than 5 mm in diameter. Laugier-Hunziker syndrome is considered to be a benign disease with no systemic manifestation or malignant potential. Therefore, it is important to rule out other mucocutaneous pigmentary disorders that do require medical management. Prompt clinical recognition also averts the need for excessive and invasive procedures and treatments. In India, the reported cases of this syndrome are very few. We provide a review of literature on Laugier-Hunziker syndrome with its differential diagnosis.

Canadian hand dermatitis management guidelines

BACKGROUND

Hand dermatitis (HD) is one of the most common skin conditions; however, it is not a homogeneous disease entity. The severity of HD may range from very mild cases to severe chronic forms, which may result in prolonged disability and, occasionally, refractory HD. Chronic hand dermatitis (CHD) is associated with a high health- economic burden and significant loss of quality of life.

OBJECTIVE

Although numerous treatment options are available, the management of CHD is often difficult and unsatisfactory. There is a paucity of well-designed, randomized, controlled clinical trials in support of the efficacy of established treatment modalities.

CONCLUSION

These guidelines cover the epidemiology, burden, quality of life, etiology, diagnosis, classification, and prevention of HD and provide guidance on management using an approach that is as evidence based as possible.

Do you know this syndrome?

Laugier-Hunziker syndrome is an acquired macular hyperpigmentation of the oral and genital mucosa, often associated with longitudinal melanonychia. We report a case of longitudinal melanonychia on fingernails and toenails, hutchinson's signal and lenticular pigmentation of her lips and oral mucosa. Histopathological analysis is typical and had a broad differential diagnosis. This is a rare and benign entity, which should be included in the differential diagnosis of mucocutaneous hyperpigmentation.
