DefinitionThis section has been translated automatically.
Not uniformly defined and used (clinical and histological) term for a usually 0.1-0.3 cm large, but also larger (up to 3.0 cm), acquired (e.g. due to actinic influences = lentigo solaris = lentigo senilis), seasonally non-reversible, brown pigment spot of the skin and/or mucosa (lentigo of the mucosa/melanoticspots of the mucosa), caused by a linear proliferation of basal melanocytes.
The "freckles" seen in fair-skinned young children in the summer months are not called lentigines, but ephelides. Unlike lentigines, they completely regress during the winter months.
