Abstract:
Although the dermatologic community rarely uses "Weber-Christian Disease" as a diagnosis, it still appears in the internal medicine literature. Herein we present a patient with recurrent cutaneous and subcutaneous nodules who was initially treated with aggressive immunosupression for a presumptive diagnosis of Weber-Christian Disease. After more than a decade the patient was diagnosed with cutaneous Mycobacterium chelonea. This case is an excellent example of the difficulty in diagnosing mycobacterial infections and underscores the importance of having a high suspicion for infectious etiologies for unresponsive cutaneous eruptions in patients on immunosuppressive medications.
