Ameloblastoma with adenoid features: Case report with cyto-histopathologic correlation and molecular findings.

Ameloblastomas are benign but locally aggressive odontogenic tumors that commonly present as expansile lesions in the tooth-bearing areas. Fine-needle aspiration (FNA) biopsies of ameloblastomas are rare in clinical practice, and only a handful of case reports and series have described their cytologic features. We present the case of a 70-year-old woman with a large and disfiguring maxillary sinus soft tissue mass sampled via transcutaneous FNA.

Distinct patterns of gene expression in human cardiac fibroblasts exposed to rapamycin treatment or methionine restriction.

Both methionine restriction and rapamycin treatment are robust longevity-enhancing regimens for which the mechanisms remain unclear. Cellular senescence is a major contributor to the aging process, and we find that both the methionine and rapamycin regimens delay or prevent activation of the senescence program in human cells. Using a transcriptome-wide analysis, we examined the impact of methionine restriction and rapamycin treatment on senescence-associated gene expression in human cardiac fibroblasts.

Malignant Triton Tumors in Sisters with Clinical Neurofibromatosis Type 1.

Malignant triton tumors (MTTs) are rare and aggressive sarcomas categorized as a subgroup of malignant peripheral nerve sheath tumors (MPNSTs). MTTs arise from Schwann cells of peripheral nerves or existing neurofibromas and have elements of rhabdomyoblastic differentiation. We report the occurrence of MTTs in two sisters.
