Refractory Hidradenitis Suppurativa: A Diagnosis to Consider

Abstract

Hidradenitis suppurativa is a chronic inflammatory disease associated with multiple comorbidities, and its association with lymphoma has recently been a topic of debate. However, it is still controversial whether this risk can be attributed to the disease itself or whether it has any relationship with immunosuppressive treatment. Here, we describe the case of a patient with severe perianal hidradenitis suppurativa treated with methotrexate and infliximab, whose exacerbation with persistence of severe symptoms refractory to adequate treatment led to the diagnosis of diffuse large non-Hodgkin B-cell lymphoma. It was decided to perform a colostomy to improve perianal sepsis, and immunochemotherapy was proposed.
