Pancreatic metastasis of malignant ocular melanoma Feb 26, 2009
A 43-years-old woman, diagnosed 4 years ago with a malignant ocular melanoma, removed by surgery and further treated by combined chemo-radiotherapy. Transabdominal ultrasound and contrast-enhanced CT showed a 20 mm tumor in the neck of the pancreas. EUS showed peripheral signals in power Doppler mode (Fig. 1). EUS-FNA with immunocytochemistry showed an intense cytoplasmatic and nuclear immunostaining for S100 and an intense cytoplasmatic immunostaining for HMB45 (Fig. 2).
