Ringworm on the Legs of a Patient after Long-term Intensive care Unit Residency

Her significant prior medical history included a Non-Hodgkin Lymphoma type B, stage III (Ann Arbor staging) diagnosed and treated since 2015. In the ICU, she received Cotrimoxazole 960 mg/250ml intravenously twice a day for 4 weeks treatment for the primary disease as well as rehabilitation to prevent muscle atrophy. After clinical improvement, the patient was transferred to the normal ward. In the clinical examination follow up we noticed flat brown itchy spots on the skin in her legs. The spots developed a slightly raised border that expanded outward, forming a circular ring. The interior of the spot was clear and smooth (Figure 1).
