Laugier-Hunziker syndrome is a rare benign condition characterized by diffuse oral hyperpigmentation associated with pigmentation of the nails. The syndrome must be included in the differential diagnosis of diffuse oral pigmentation to exclude other conditions with systemic implications. We describe a 43-year-old white woman with the clinical and histological features of Laugier-Hunziker syndro...
Cosmetic expectations have increased with time and current trends speak volumes about gingival esthetics and smile designing. Gingival pigmentation especially on the labial aspect of anterior teeth has become an important component of general esthetics. Various physiologic and pathologic factors cause gingival pigmentation. The existing indices do not deal with the etiology, extent and severity...
introduction: dark or black coloured gingiva is an esthetic concern especially in subjects with high lip line or gummy smile. gingival depigmentation procedure is a type of perioplastic surgery where the gingival epithelium is excised with various techniques to lighten the colour of the gingiva. the aim of this study was to compare the clinical efficacy of gingival depigmentation procedure with...
we describe a 69-year-old-woman with antecedent of breast cancer and recent transitory neurological symptoms. physical examination showed yellow to orange skin pigmentation, more conspicuous on her palms and soles, while discoloration changes were absent in the eye and oral mucous membranes. routine laboratory findings were not indicative of hemolytic anemia, liver or bile disorders, nephrotic ...
It is extraordinarily difficult to recognize a face in an image with negated contrast, as in a photographic negative. The variation among faces can be partitioned into two general sources: (a) shape and (b) surface reflectance, here termed 'pigmentation'. To determine whether negation differentially affects the processing of shape or pigmentation, we made two sets of faces where the individual ...
Pigmentation is both the normal and abnormal discoloration of oral mucous membrane. Pigmentation has multifactorial etiology. Most of the pigmentation is physiologic but sometimes it can be a precursor of severe diseases. Melanin pigment irregularities and color changes of the oral tissues could provide significant diagnostic evidence of both local and systemic disease. The differential diagnos...
Melasma is a complex multifactorial disorder whose pathogenesis is not well understood. In addition to increased pigmentation, increased vascularity associated with pigmentation is present. A variety of topical treatments targeting pigmentation are available with temporary improvement of mainly the epidermal components of melasma.

Abnormal pigmentation of Senegalese sole has been described as one problem facing the full exploitation of its commercial production. To improve our understanding of flatfish pigmentation of this commercially important species we have evaluated eleven genes related to two different processes of pigmentation: melanophore differentiation, and melanin production. The temporal distribution of gene ...
