Angiokeratoma is a rare, cutaneous vascular disorder that can occur in several clinically distinct conditions. It usually presents as multiple, red to blue or black, asymptomatic papules on the skin. Oral mucosal involvement is common in the systemic form, but very rare in the localized forms of angiokeratomas. We report the second case of a solitary papular angiokeratoma of the oral cavity.
Laugier-Hunziker syndrome (LHS) is an acquired, benign, macular hyperpigmentation of the lips and oral mucosa, often associated with pigmentation of the nails. It is a rare disorder thought to be more common than the number of reported cases would suggest. It is important to include this condition in the differential diagnosis of diffuse oral pigmentation. Here we report the first case of the Laugier-Hunziker syndrome in Scandinavia. Other conditions causing diffuse or multifocal pigmented oral lesions are discussed.
