Chronic prurigo may reveal several internal diseases. Its association with a solid neoplasia is rare. We report an exceptional case of chronic prurigo revealing surgically curable adenocarcinoma of the ampulla of Vater. Our study involved a 70-year old patient, with no particular previous history, who was hospitalized for etiological assessment of prurigo lasting for 06 months associated with non-documented weight loss. The lesions were isolated and involved the trunk and the limbs (A); initial assessment was strictly normal. Given the lack of patient's improvement with symptomatic treatment, additional exams were performed, including thoracoabdominopelvic CT scan, which objectified a tumor of the biliopancreatic junction measuring 2 cm, suggesting the diagnosis of ampulloma (B). The patient underwent surgical excision of this adenocarcinoma of the ampulla of Vater followed by regression of the skin lesions without further treatment. At 1-year follow-up, there was no evidence of recurrence of the skin lesions and the patient achieved complete remission of adenocarcinoma.
