Problems of diagnosis of gangrenous pyoderma and drug-induced lower limb myopathy in a patient with ulcerative colitis

Abstract

A clinical observation of the patient is presented, where the verification of ulcerative colitis was difficult due to the fact that intestinal symptoms required a differential diagnosis. A definition of the etiological identity of the skin rash was also required. The diagnosis was promoted by identification of gangrenous pyoderma. During the treatment of ulcerative colitis, the patient developed a proximal myopathy of the lower limbs, which, after conducting a diagnostic search, was regarded as a side effect of sulfasalazine, and the abolition of the drug led to the complete elimination of muscle damage.
