Cutaneous sarcoidosis successfully treated with topical tacrolimus

Sarcoidosis is a disorder characterized by macrophage- and T-cell-mediated responses to as yet unidentified infectious antigens or autoantigens. We describe a 62-year-old woman with a 10-year history of orange-yellow plaques of sarcoidosis on her face. Her cutaneous lesions responded to topical tacrolimus ointment after unsuccessful treatment with topical and systemic corticosteroids. No adverse effects were noted with topical tacrolimus in this patient. We discuss the mode of action by which this immunosuppressive agent may act against sarcoidosis.     

Granuloma faciale successfully treated with topical tacrolimus

Granuloma faciale (GF) is a benign chronic condition characterized by recurrent plaques and nodules most commonly found on the face. We report a man with a 6-month history of plaques on his forehead and preauricular area consistent with GF that responded to twice-daily application of topical tacrolimus ointment, and who remains in remission 1 year later. This case supports previous reports of the successful use of topical tacrolimus in treating GF.     

Mouth ulcers in patients receiving tacrolimus

INTRODUCTION: The buccal side effects of immunodepressors are well defined with cyclosporine and certain antimitotic agents. We report a case of buccal ulcerations in a patient treated with a new immunosuppressive macrolide: tacrolimus (Prograf). OBSERVATION: A 53 year-old woman presenting a severe cardio-myopathy, underwent heart transplantation in May 1997. Tacrolimus was introduced in October 1997 after 3 episodes of acute reject. Eight months after tacrolimus, painful apthoid buccal ulcerations appeared. Biopsy of the buccal mucosa and other biological examinations revealed no particular etiology. Since tacrolimus could not be stopped, treatment with thalidomide was initiated. It was suspended on two occasions due to adverse events. The buccal ulcerations relapsed rapidly. The intrinsic imputability of tacrolimus in the occurrence of these lesions was noted "l2" ("plausible"). DISCUSSION: Several arguments suggest that these buccal ulcerations may result from the toxicity of tacrolimus: 1) absence of past history of apthae; 2) anatomo-clinical aspect of the lesion differing from that of common apthae, but similar to the ulcerations observed with nicorandil; 3) delay in occurrence of analogous ulcerations compared with that observed with methotrexate or nicorandil; 4) absence of another etiology; 5) relapse of ulcerations on two occasions after suspension of thalidomide, whilst tacrolimus was continued.     

A case of Darier''s disease successfully treated with topical tacrolimus

Tacrolimus is a macrolide that inhibits T-cell activation. The most extensive experience with topical tacrolimus has been in treating atopic dermatitis but it has been used in various skin diseases, including Hailey-Hailey disease, with encouraging results. We report a case of extensive Darier's disease successfully treated with topical tacrolimus, after suspension of oral isotretrinoin due to major depression.
