A Case Report on a Recurring Rash: Mild Chronic Superficial Perivascular Dermatitis With Epidermal Ulcerations

This case report presents a 53-year-old male with a five-month history of ongoing purpuric, blistering, and ulcerative rash on his bilateral lower extremities that extended upward to his torso, back, and upper extremities. Although the patient was placed on numerous antibiotics, the rash persisted and continued to cause the patient distress. During his multiple hospital admissions, repeated wound cultures grew <i>Enterobacter aerogenes</i>, <i>Enterobacter cloacae</i>, <i>Escherichia coli</i>, <i>Klebsiella oxytoca</i>, and recurrent methicillin-resistant <i>Staphylococcus aureus</i> (MRSA). Skin biopsy showed mild chronic superficial perivascular dermatitis with epidural ulceration and no evidence of leukocytoclastic vasculitis. This case report highlights the difficulties in the management of complicated cases of dermatitis and the importance of quick diagnoses, compliance, and outpatient follow-up.
