Four distinct ipsilateral vestibular schwannomas: A case of mosaic NF2-related schwannomatosis
CONCLUSIONS: Multimodality sequencing, including NGS, MLPA, and OGM, was required to ensure appropriate diagnosis of mosaic NF2-related schwannomatosis in this patient. A similar approach can be used for other patients with multiple ipsilateral tumors and suspected tumor predisposition.PMID:38527168 | DOI:10.1093/ajcp/aqae027 (Source: American Journal of Clinical Pathology)

Interobserver reproducibility of cervical histology interpretation with and without p16 immunohistochemistry
CONCLUSIONS: Adjunctive p16 immunostaining provides useful information in the evaluation of cervical biopsies for precancer. In our study, we have demonstrated that it is highly reproducible between 2 pathologists, although the decision of which biopsies warrant its use is less so. Furthermore, although p16 IHC showed a limited increase in diagnostic reproducibility for all biopsies included in our study, it did demonstrate a more sizable gain in biopsies negative for HPV 16 but positive for other high-risk genotypes. Further studies are needed to clarify the role of p16 IHC and how it can be optimized for the detection of...

How I diagnose and manage VEXAS syndrome
CONCLUSIONS: Either clinicians or pathologists may suspect a diagnosis of VEXAS syndrome depending on the clinical presentation and bone marrow findings. More studies are needed to determine the best therapeutic options, which are currently limited.PMID:38511841 | DOI:10.1093/ajcp/aqae017 (Source: American Journal of Clinical Pathology)

Morules and β-catenin predict POLE mutation status in endometrial cancer: A pathway to more cost-effective diagnostic procedures
CONCLUSIONS: Our findings suggest that the presence of either morules or nuclear β-catenin expression in EEC could practically rule out the presence of POLE mutations. These morphologic and immunohistochemical features can be used as preliminary screening tools for POLE mutations, offering significant savings in time and resources and potentially enhancing clinical decision-making and patient management strategies. However, further validation in larger, multi-institutional studies is required to fully understand the implications of these findings on clinical practice.PMID:38513273 | DOI:10.1093/ajcp/aqae023 (Source: Ameri...

Clinicopathologic correlation of dermatologic diseases in patients with darker pigmentation
CONCLUSIONS: As many clinicians are taught that there are no effective treatment options or that these diseases are considered "cosmetic" in nature, patients often do not get a thorough medical workup or skin biopsy. This article aims to decrease the knowledge gap and serve as a resource for anyone involved in the care of patients with these cutaneous conditions.PMID:38513285 | DOI:10.1093/ajcp/aqae013 (Source: American Journal of Clinical Pathology)
