Pyoderma gangrenosum associated with limited cutaneous systemic sclerosis: a rare case with literature review
2020
Pyoderma gangrenosum (PG) is a skin disease characterized by painful ulcers that, when not appropriately treated, can lead to permanent disfigurement. Pyoderma gangrenosum has been observed in a multitude of autoimmune disorders such as rheumatoid arthritis, inflammatory bowel disease (IBD), and sarcoidosis (Feld et al. J Rheumatol. 39(1):197, 2012; Herrero et al. J Rheumatol. 36:7:1557–1558, 2009). It is rarely associated with autoimmune disorders such as systemic sclerosis. We report a case of a patient with known limited cutaneous systemic sclerosis who developed an ulcerated lesion on the 2nd digit of the left hand. The lesion was initially thought to be cellulitis and the patient underwent superficial wound debridement. Postoperatively, the patient’s lesions worsened. The patient was treated with intravenous (IV) methylprednisolone and 0.05% topical clobetasol due to high suspicion for PG with complete resolution of ulcerated lesions and minimal scarring.
