Indications and recommended approach for surgical intervention of metastatic disease to the gallbladder

Abstract: Metastatic disease to the gallbladder is unusual. The most common malignancy metastatic to the gallbladder is melanoma, followed by renal cell carcinoma (RCC) and breast cancer. Due to the unusual nature of the disease, there are no trials available for review. Thus, the management for these patients has been based on institutional experience and review of case series. The indications for surgical intervention for melanoma are metastatic disease discrete to the gallbladder and biliary symptoms, which are uncom… Show more

“…Therefore, a laparoscopic approach seemed to be adequate for this case. [4][5][6] Despite detailed examination of the skin and retina, we could not determine where the primary site was or whether the gallbladder was a primary or metastatic lesion. However, the malignant melanoma was detected in at least 2 organs and was also suspected in other organs; hence, we diagnosed her with stage IV metastatic malignant melanoma and performed systemic chemotherapy postoperatively.…”

“…CT of the abdomen in metastatic melanoma show hyperdense mass, polyp, or focal thickening of gallbladder wall with contrast enhancement in the early stage and variable enhancement in the equilibrium stage [101]. But CT does not show efficient sensitivity or specificity and can lead to misdiagnosis (as cholesterol polyp [63] or liver mass [77]) or underdiagnosis [65,90,98]. Sometimes CT studies can favor a diagnosis of gallbladder cancer instead of metastatic disease [53].…”

“…conducto cístico o la erosión local de la mucosa en la génesis de la inflamación. (1,2) Los tumores primarios de la vesícula biliar (VB) son infrecuentes; la mayoría son adenocarcinomas asociados a litiasis e inflamación crónica del órgano, y afectan mayormente a mujeres adultas e individuos de color banco de la piel. (3,4) En cuanto a los tumores metastásicos, su incidencia es de alrededor del 5 al 15% por lo que es un acontecimiento relativamente raro.…”

“…Se han reportado con mayor frecuencia secundarios a invasión directa de tumores intrabdominales originados fundamentalmente en colon y estómago, o a diseminación hematógena de melanomas malignos cutáneos, carcinoma de células renales, carcinoma lobular de la mama femenina, carcinoma de células pequeñas de cérvix uterino, adenocarcinoma de recto, cáncer de pulmón. (2) El diagnóstico de Melanoma maligno (MM) en la VB responde a evento metastásico en el 30-60% de los casos; no obstante, algunos melanocitos pueden migrar desde la cresta neural a los tejidos de origen endodérmico durante la embriogénesis (5)(6)(7)(8)(9)(10) por lo que pueden encontrarse en leptomeninges, cerebro, retina, corazón, vía oral, esófago, intestinos, vesícula biliar y región anorrectal, mucosa nasal y respiratoria, tracto genitourinario, el tejido adiposo, la adventicia de vasos sanguíneos, la fascia muscular, ganglios linfáticos. (2,5,6,11) Así, después de su migración y diferenciación, pueden dar lugar a un melanoma de mucosa en cualquier sitio anatómico, representando alrededor del 1% de estos.…”
