Occupational dermatoses in cheese makers: frequent association of irritant, allergic and protein contact dermatitis.

BACKGROUND

Few data are available on occupational dermatoses in cheese makers.

OBJECTIVE

The purpose of the present study was to investigate occupationally related skin diseases in cheese makers.

METHOD: In a retrospective study we analyzed 400 patients with occupational dermatoses which presented for expert opinion evaluation at our institution (1990-1995).

RESULTS

Four patients with hand eczema acquired in cheese dairies were identified. All patients had a decreased alkali resistance. Atopy was a further risk factor in 2 patients. Three out of 4 patients were patch test positive for occupationally related substances and demonstrated also immediate skin test reactions to various milk products. Therefore, these patients had concurrent allergic contact and protein contact dermatitis.

CONCLUSION

The diagnosis of concurrent allergic and protein contact dermatitis has to be considered in occupational dermatoses related to cheese making.
