From variant of unknown significance to likely pathogenic: Characterization and pathogenicity determination of a large genomic deletion in the MLH1 gene.

Background: The MLH1 gene is one of the DNA mismatch repair genes (MMR), implicated in Lynch syndrome (LS), an autosomal dominant hereditary tumor susceptibility disease. The advent of next-generation sequencing (NGS) technologies has accelerated the diagnosis of inherited diseases and increased the percentage of diagnosis of inherited cancers. However, some complex genomic alterations require the combination of several analytical strategies to allow correct biological interpretations.

Large-cell neuroendocrine tumor of the prostate: a case report and review of the literature.

Background: Primitive neuroendocrine prostate neoplasms are rarely reported. This entity comprises carcinoïd tumors and poorly differentiated neuroendocrine tumors, mainly those of the small-cell type. Large-cell-type primitive tumors are exceptional, and only nine cases are reported in the literature.

Clinicopathologic analysis of acute myeloid leukemia arising from chronic myelomonocytic leukemia.

Acute myeloid leukemia arising from chronic myelomonocytic leukemia is currently classified as acute myeloid leukemia with myelodysplasia-related changes, a high-risk subtype. However, the specific features of these cases have not been well described. We studied 38 patients with chronic myelomonocytic leukemia who progressed to acute myeloid leukemia.
