A 66-year-old African American man with a history of multiple comorbidities was referred for evaluation of an umbilical mass (Figure 1) that was present for several months. He noticed the lesion at approximately the same time that he started experiencing abdominal pain. He reported serous drainage when picking at the lesion and experienced tenderness on palpation. Additionally, he endured night sweats, occasional chills, a 20-lb weight loss, and anorexia. Otherwise, he denied constipation, melena, hematochezia, nausea, vomiting, and diarrhea. His family history was noncontributory.
