Spontaneous Cholecysto-Cutaneous Fistula.

An 87-year-old female patient presented to our surgical department with complaints of persistent right upper abdominal pain lasting for three months and an inflammatory subcostal mass on the right side. The patient had a history of acute pancreatitis four months prior. On abdominal examination, a 6 cm abscess was noted in the right subcostal area, accompanied by cellulitis and discharge of bile and gallstones (Figure 1 Panel A and B). Laboratory results showed an elevated white blood cell count of 17000/mm3 and a CRP level of 170mg/dl, while other parameters were within normal limits.
