Anamnesis And Clinical ExaminationA 56-year-old male patient consulted our surgical department presenting repetitive pain in his right upper abdomen and already known cholecystolithiasis. There were no other findings in the clinical examination; fever or abnormalities concerning bowel movement or micturition were denied. Except from the extirpation of a melanoma and an appendectomy years ago there were no relevant previous illnesses.DiagnosisAn external CT-Scan of the abdomen revealed a cholecystolithiasis and an unclear thickening of the gallbladder wall near the infundibulum. Blood results showed no relevant pathologic excursion.Therapy And Clinical CourseAfter uncomplicated laparoscopic cholecystectomy the results of the histopathologic examination revealed a metastasis of the melanoma, which was diagnosed and excised years ago. Additional staging showed pulmonal metastasis and resection in palliative intention was performed.ConclusionGallbladder metastasis of any cancer entities are a rare event, but some studies suggest that the number of events is underestimated concerning the malignant melanoma.If there is a corresponding medical history, symptoms should quickly lead to determined diagnosis and, if in doubt, to cholecystectomy.Thieme.
