[Several cases of non-phlebologic pigmentation of the lower extremities]

Hyperpigmentation of the lower limbs does not always reflect a phlebological abnormality. The authors briefly recall other pathological circumstances which result in cutaneous hyperpigmentation : cutaneous porphyria (hyperpigmentation of the exposed parts), malignant melanoma, Recklinghausen's neurofibromatosis (café-au-lait spots and naevo-cellular naevi), pigmented dermatoses (lichen planus), fixed pigmented toxidermias, drug induced hyperpigmentations (minocyne, synthetic anti-malarials which can provoke the development of large areas of greyish coloured s in), reticular "hot water bottle" dermatitis and malingering syndromes.
