Multifocal pyoderma gangrenosum secondary to subclinical diverticulitis: case report and brief literature review.

Pyoderma gangrenosum is characteristically associated with inflammatory bowel disease. However, the association between this neutrophilic dermatosis and diverticular disease is scarcely mentioned in the literature. Diverticulitis should be included in the differential diagnosis in patients with pyoderma gangrenosum and gastrointestinal complaints, or even in asymptomatic patients, particularly in the elderly. Misdiagnosis can lead to inadequate treatments and serious complications.
