Approximately 74% of the cases were associated with systemic disease. The most frequent were inflammatory bowel disease (32%) and hematologic malignancies (22%). Pyoderma gangrenosum preceded the associated disease in 26% of the patients, all of them were younger than 50\u00a0years old (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.059). In 83% of the latter, the diagnosis of associated disease followed the cutaneous lesions within 24\u00a0months.

The results of our study underline the importance of doing screening tests to detect potential disease, emphasizing patients younger than 50\u00a0years old, for a minimum time lapse of 24\u00a0months. It is essential to design randomized\u2010controlled trials to understand the most appropriate and effective ways of following up patients with pyoderma
