[Cerium-induced granulomatous dermatitis].

Abstract

BACKGROUND:

The presence of inorganic foreign bodies in granulomatous cutaneous lesions is not infrequent. In this paper, we describe the first case of cerium-induced cutaneous granulomatous dermatitis.

CASE REPORT:

A 57-year-old woman seriously burned four years ago presented with papulonodular lesions affecting only the burned areas treated with topical cerium nitrate-silver sulfadiazine cream (Flammacérium). Biopsies revealed sarcoidal granuloma associated with exogenous particles. Electron probe X-ray microanalysis demonstrated a high cerium content. Screening for systemic sarcoidosis was negative. The patient was treated with hydroxychloroquine. After four months of follow-up, clinical and histological evidence of decreased infiltrate was noted.

DISCUSSION:

Cerium nitrate-silver sulfadiazine cream (Flammacérium) is widely used for the topical treatment of burns. The main effect of cerium is to create superficial calcification, which decreases wound colonization and prevents the formation of granulation tissue (no hypertrophic scar formation) in burns. Prior to our case, no cutaneous side-effects of cerium had been encountered. Inoculation of foreign matter may or may not induce granuloma formation or sarcoidosis in different subjects, according to their immunologic status. The favorable outcome in this case could in fact be due to a change in the pattern of cytokinin production (TH1=> TH2) rather than the effects of hydroxychloroquine therapy.
