Lymph node staging with fluorine-18 prostate specific membrane antigen 1007-positron emission tomography/computed tomography in newly diagnosed intermediate- to high-risk prostate cancer using histopathological evaluation of extended pelvic node dissection as reference
Fluorine-18 (18F) prostate–specific membrane antigen (PSMA) 1007 (18F-PSMA-1007) is a radiotracer used in prostate cancer (PCa) staging. So far, no large histopathological validation study has been conducted. The...

Open AccessPoor outcome in hypoxic endometrial carcinoma is related to vascular density
Identification of endometrial carcinoma (EC) patients at high risk of recurrence is lacking. In this study, the prognostic role of hypoxia and angiogenesis was investigated in EC patients.

Open AccessSF3B1 and EIF1AX mutations occur in primary leptomeningeal melanocytic neoplasms; yet another similarity to uveal melanomas
Like uveal melanomas, primary leptomeningeal melanocytic neoplasms (LMNs) frequently carry GNAQ and GNA11 mutations. However, it is currently unknown whether these LMNs harbor mutations in BAP1, SF3B1 and/or EIF1...

Mutations in G Protein Encoding Genes and Chromosomal Alterations in Primary Leptomeningeal Melanocytic Neoplasms
Limited data is available on the genetic features of primary leptomeningeal melanocytic neoplasms (LMNs). Similarities with uveal melanoma were recently suggested as both entities harbor oncogenic mutations in GN...

Open AccessImproved discrimination of melanotic schwannoma from melanocytic lesions by combined morphological and GNAQ mutational analysis
The histological differential diagnosis between melanotic schwannoma, primary leptomeningeal melanocytic lesions and cellular blue nevus can be challenging. Correct diagnosis of melanotic schwannoma is importa...

Open AccessActivating mutations of the GNAQ gene: a frequent event in primary melanocytic neoplasms of the central nervous system
Primary melanocytic neoplasms of the central nervous system (CNS) are uncommon neoplasms derived from melanocytes that normally can be found in the leptomeninges. They cover a spectrum of malignancy grades ran...

Open AccessOccurrence of ocular melanoma thirteen years after skin melanoma: two separate primaries or metastatic disease? A case solved with NRAS and CDKN2A (INK4A-ARF) mutational analysis
The differential diagnosis between primary uveal melanoma and cutaneous melanoma metastasis in the eye may be difficult, both clinically and histologically. We report successful application of combined mutatio...
