Silver-blue nails.

The case is reported of a man with uniformly silver-blue discolouration of all fingernails, with deeper colouring over the lunulae. The nail bed changes resulted from the uncontrolled ingestion of a silver-containing granular powder. The total silver intake was over 15 g. The only other sign of argyrosis was a barely perceptible greyish discolouration over the cheeks and in the sclerae. Biopsies were taken from the nail bed and the cheek. Electron microscopy revealed metallic deposits in elastic fibres and basement membranes. The silver deposition was much heavier in the nail bed than in facial skin. Long-wave ultraviolet light (UVA) and lack of melanin protection seem to be responsible for this phenomenon. Argyrosis and the differential diagnosis of nail discolourations are reviewed.

[The problem of vitamin B6/B12 acne. A contribution on acne medicamentosa (author's transl)].

Deterioration of acne vulgaris or eruption of an acneiform exanthema could be established during treatment with vitamin B6 and/or vitamin B12 in 14 patients. Females were by far the more frequently affected. The appearance of skin symptoms, even outside the age groups typically affected by acne vulgaris is characteristic. The clinical appearance of acneiform exanthema occurring during treatment with vitamin B6 or B12 consists of loosely disseminated small papules or papulopustules on the face (especially on the forehead and chin), on the upper parts of the back and chest and spreading to the upper arm. The pathogensis of the change is not yet certain. The acneiform rash generally fades within a short time after vitamin B6 or vitamin B12 treatment has been stopped.
