Junctions of endoplasmic reticulum and virus like intranuclear inclusions and virus like intranuclear inclusions in amelanotic melanoma metastatic to the jejunum.

Antemortem diagnosis of amelanotic metastatic melanoma to jejunum was made in a 35-year-old white man, who is still alive and healthy. Electron microscopy, in addition to finding premelanosomes, revealed virus-like intranuclear inclusions. Nuclear pockets and junctions of endoplasmic reticulum were also observed.
