SPLEEN - Metastatic melanoma

Description of Specimen
The specimen is a grossly enlarged spleen expanded by nodular tumour in which there are areas of haemorrhage. At the upper pole there is an organising subcapsular haematoma.
A melanoma of the skin was removed from this man at the age of 64; six years later he presented with abdominal pain and a mass in the right hypochondrium. At laparotomy an enlarged spleen showing a subcapsular haematoma was found and removed. The spleen weighed 1108 grams; the histology was that of metastatic melanoma.
