Laugier-Hunziker syndrome: case report and treatment with the Q-switched Nd-Yag laser

We report the case of a 46-year-old Caucasian female presenting with mucocutaneous pigmentation on the lips, oral mucosa, hands, feet and nails, as well as on a psoriatic plaque. She was successfully treated with Q-switched Nd-Yag laser, with double frequency, for both the mucosal and cutaneous lesions.     

A Case of Laugier-Hunziker Syndrome

Laugier-Hunziker syndrome is a rare idiopathic acquired hyperpigmentation of oral mucosa and lips which is often associated with longitudinal melanonychia. This condition is known to be an entirely benign disease with no systemic manifestations. Herein we report a case of a 54-year-old woman presenting with a 7-year history of asymptomatic oral pigmentation and linear pigmented streaks of several fingernails. Histological examination taken from the mucosal lesion of tongue revealed increased pigmentation at the epithelial basal layer and a few melanophages in the submucosa. The lack of a family history coupled with the absence of any polyps on the endoscopic examinations of upper and lower bowel as well as the clinical features with late onset were all in favor of a diagnosis of Laugier-Hunziker syndrome. The significance of this disease is due to the need to differentiate this disorder from other pigmentary disorders of the oral mucosa, especially Peutz-Jeghers syndrome.     

Laugier-Hunziker syndrome

Laugier-Hunziker syndrome is a benign pigmentary disorder which manifests as macular hyperpigmentation of the lips and buccal mucosa. Some patients have longitudinal pigmented bands of nails. The syndrome has no systemic associations. Two patients of this rare syndrome are reported. Disorders producing similar pigmentary changes which must be differentiated are discussed.     

Pseudo-melanoma revealing Laugier-Hunziker syndrome

A 47-year-old Arabic woman presented with a few months history of a 20 × 10 mm brown-black interdigital macule, irregular in shape and outline (Fig. 1). The patient had no previous personal or familial history of dysplastic nevi, melanoma, or gastrointestinal polyposis. She was receiving fluindione, furosemide, digoxin. and lisinopril dihydrate for chronic atrial fibrillation. She had a mitral valvular bioprothesis secondary to rheumatic heart disease.
On physical examination there were no enlarged lymph nodes. Multiple pigmented macules were noted on the lower lip and buccal mucosa (Fig. 2). Genital mucosa showed no pigmentary abnormalities. There were also many pigmented longitudinal streaks involving five finger- and two toenails without Hutchinson's sign, two brownish interdigital macules of the fingers (Fig. 3), and dark brown spots around the nails. Clinical examination of her two sisters and three children did not demonstrate mucocutaneous pigmentation.
Investigations showed normal renal, hepatic, and thyroid function. Human immunodeficiency virus serology was negative. Two-punch biopsy 4×4 mm of the right darkness and left edges of the interdigital lesion confirmed the diagnosis of Laugier-Hunziker syndrome with basal hypermelanosis without melanocytic proliferation or cytologic atypia (Fig. 5). After 2 years follow-up, clinical and histologic examination was not modified.     

Dermoscopic findings in Laugier-Hunziker syndrome

BACKGROUND: Laugier-Hunziker syndrome (LHS) is a rare, acquired mucocutaneous hyperpigmentation often associated with longitudinal melanonychia. The clinical behavior of mucocutaneous pigmented lesions ranges from benign to highly malignant. Therefore, in most cases, the clinical diagnosis should be confirmed by further diagnostic methods. Dermoscopy is a noninvasive technique that has been used to make more accurate diagnoses of pigmented skin lesions. Nevertheless, to our knowledge, the dermoscopic features of the pigmented lesions in LHS have not been described previously. Herein, we report a case of LHS together with its dermoscopic features. OBSERVATIONS: The clinical examination revealed macular hyperpigmentation on the oral and genital mucosa, conjunctiva, and palmoplantar region together with longitudinal melanonychia. Dermoscopic examination of mucosal lesions on the patient's lips and vulva revealed a parallel pattern. Longitudinal homogeneous pigmentation was observed on the toenails. The pigmented macules on the palms and the sole showed a parallel furrow pattern. A skin biopsy sample taken from the labial lesion was compatible with a diagnosis of mucosal melanosis. CONCLUSIONS: By means of this case report, the dermoscopic features of the pigmented lesions in LHS are described for the first time, which facilitates diagnosis with a noninvasive technique. Future reports highlighting the dermoscopic features of this syndrome may simplify the diagnosis of LHS, which is thought to be underdiagnosed.
