Recurrent Bacterial Infections in Cutaneous T-cell Lymphoma

Abstract

Cutaneous T-cell lymphoma (CTCL) is a dermatologically manifesting immune cell disorder. We present a case of a 76-year-old female with a past medical history of CTCL, presenting with cellulitis of the left foot. After diagnosis of CTCL, the patient was admitted multiple times for treatment of cutaneous and soft-tissue infections with methicillin-resistant Staphylococcus aureus. Her recurrent infection with S. aureus had led to treatment for sepsis and a below-knee amputation on the right during prior hospitalizations. On this admission, the patient was treated with intravenous vancomycin and cefepime as in-patient and oral linezolid as out-patient. Recent articles show that patients with CTCL have an increased tendency to harbor S. aureus, which leads to recurrent infections. Additionally, evidence suggests that S. aureus toxins aid the progression of CTCL by helping the cancer to escape immune regulation. Our patient demonstrates this unique relationship between CTCL and S. aureus, and moreover, we make a case that S. aureus infection in CTCL, as compared to that in other dermatitis, should be better managed to not exacerbate the disease.
