The authors describe the first case of eye amelanotic cellular blue nevus reported in literature and discuss the main differential diagnosis.
UNLABELLED Cerenkov luminescence imaging (CLI) can provide high-resolution images of (18)F-FDG-avid tumors but requires prolonged acquisition times because of low photon sensitivity. In this study, we proposed a new modality, termed β-radioluminescence imaging (β-RLI), which incorporates a scintillator with a γ-rejection strategy for imaging β particles. We performed a comparative evaluation of...
Case In April 2012, a 69-year-old Chinese woman complained of a non-healing raised lesion over the lateral aspect of her left fifth toe which had developed 2 years earlier. It appeared to have started as a minor abrasion after wearing ill-fitting shoes. A painless swelling then developed over that site with occasional friction-induced bleeding. She attended several podiatry treatment sessions a...
BACKGROUND Primary melanoma of the vagina is an extremely rare neoplasm with approximately 250 reported cases in the world literature 1234. In its amelanotic variant this lesion may raise several differential diagnostic problems in cytological specimens 5. In this setting, the usage of thin layer cytopathological techniques (Liquid Based Preparations = LBP) may enhance the diagnostic sensitivit...
BACKGROUND Hypomelanotic or amelanotic melanomas are challenging to identify, especially at mucosal sites. The dermoscopic clues to the diagnosis of mucosal melanomas have been reported to be structureless zones with the presence of blue, gray, or white colors. CASE A female in her seventies noted a new lesion on the inside of her right labia that first appeared two months prior. Her past med...
