Lymphoma Mimicking Pyoderma Gangrenosum: A Case Report.

Some inflammatory conditions, such as pyoderma gangrenosum, and tumoral conditions, such as lymphoma, may appear as soft tissue infections. Herein, a cutaneous lymphoma patient who was hospitalized with a diagnosis of soft tissue infection and was considered to have pyoderma gangrenosum during follow-up is presented. Immediate histopathological examination should be recommended to diagnose skin soft tissue lesions, especially long-term and unresponsive to treatment.
