A Rare Presentation of Melanoma as a Retroperitoneal Mass Seen on FDG PET

A 55-year-old woman presented with intermittent fatigue and abdominal pain. Ultrasound and CT scan showed a large heterogeneous mass in the retroperitoneum, suggestive of malignancy. 18F-FDG PET/CT was performed for staging. PET/CT images showed a hypermetabolic retroperitoneal mass. Endoscopy revealed a mass infiltrating the duodenum. Eventually, the mass was pathologically proved to be malignant melanoma. Further extensive clinical, radiological, and endoscopic investigations proved the retroperitoneum to be the primary site.

Odile Berthier-Vergnes Melanoma is the most aggressive skin cancer with an extremely challenging therapy. The dermal-epidermal junction (DEJ) degradation and subsequent dermal invasion are the earliest steps of melanoma dissemination, but the mechanisms remain elusive. We previously identified Tspan8 as a key actor in melanoma invasiveness. Here, we investigated Tspan8 mechanisms of action during dermal invasion, using a validated skin-reconstruct-model that recapitulates melanoma dermal penetration through an authentic DEJ. We demonstrate that Tspan8 is sufficient to induce melanoma cells’ translocation t...

A 56-year-old woman with a past medical history significant for cutaneous melanoma with multiple recurrences treated by surgery and immunotherapy was referred to our unit for cholecystectomy. An abdominal ultrasound performed because of intermittent right upper quadrant pain revealed a gallbladder mass. Abdominal magnetic resonance imaging found a well-defined round mass located into the infundibulum of the gallbladder (Fig. 1, panel A-B). An abdominal PET-scan revealed an isolated hyperfixation on the mass suggesting a metastasis from melanoma.

Conclusion: Both, the mTOR inhibitor everolimus as well as antiangiogenetic effects by the VEGFR inhibitor axitinib showed potential to prevent and retard formation of symptomatic spinal metastases. However, the therapeutic efficacy was only mild in this experimental model.

We present abdominal computed tomography and enteroscopy images of a 48-year-old male patient with a previous melanoma who presented with epigastric pain. The pain was not controlled with medical management. Abdominal computed tomography and a histological study of biopsies form enteroscopy confirmed the diagnosis of metastatic melanoma. The gastrointestinal involvement of melanoma is usually metastatic. Symptomatic gastrointestinal involvement occurs in less than 5% of melanomas, although postmortem analyses have reported up to 70%. The clinical presentation is variable and usually presents as abdominal pain. The diagnosi...
