[Clinical variability of polyvinylpyrrolidone dermatosis]

Several pharmaceutics on the market contain polyvinylpyrrolidone (PVP). As the high-polymeric parts of the PVP molecules cannot be eliminated after parenteral or subcutaneous application, they accumulate in the organism. PVP residues in the dermis cause a considerable variability of skin changes, ranging from deposits nearly without reactions up to swelling, papules, granulomas and pseudotumors.
