Abstract
BACKGROUND: Herein, we report a case of atypical periorificial dermatitis in a patient that had been receiving treatment for some time for atopic dermatitis. The specific feature of this rash was its periocular predominance with no perioral involvement, its clinical aspect and its histological picture evocative of sarcoidosis.
PATIENTS AND METHODS: A 33-year-old man was being treated for a atopic dermatitis limited to the face and poorly responsive to dermal corticosteroids. Treatment was initiated with topical tacrolimus 0.1%. After 4 years, dependence on this treatment was noted, with daily application being needed to control the lesions. One year later, symmetric lesions were seen on the eyelids and periorbital regions; these were erythematous, micropapular and poorly delineated in a setting of oedema. Biopsy revealed epithelioid granulomatous inflammation, and, to a lesser degree, sarcoidal giant-cell features without caseous necrosis. Staging tests to identify systemic sarcoidosis were negative. Treatment with hydroxychloroquine at 400mg per day and discontinuation of topical tacrolimus resulted in complete remission of the lesions within 2 months. Hydroxychloroquine was discontinued after 6 months, and no relapses had occurred after 2 years of follow-up.
DISCUSSION: Three diagnostic hypotheses may be posited for these granulomatous facial lesions. We opted for a diagnosis of granulomatous periorificial dermatitis despite the fact that exclusively periorbital involvement is rare (this condition is generally associated with perioral dermatitis). The second was that of pure cutaneous sarcoidosis, but the topography and clinical appearance of the lesions did not correspond to any of the cutaneous forms classically described. The third was that of tacrolimus-induced granulomatous rosacea, but the histological picture is different.
CONCLUSION: The present case underscores the fact that a histological appearance of sarcoidosis on skin biopsy may be associated with perioral dermatitis.
