Breast granular cell tumor: A case report and review of literature.

Granular cell tumor (GCT) is a rare neoplasm. Its diagnosis is based on imaging and pathological findings. There are only a few reported cases of GCT of the breast (GCTB) in the literature.

Association between renin-angiotensin antagonism and COVID-19-related mortality in patients with essential hypertension: A single center, retrospective cohort study.

There is conflicting evidence in select mouse models and humans that suggest angiotensin-converting enzyme 2 expression is increased due to treatment with angiotensin converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARBs). Given the wide range of conditions that these medications treat, further evaluation is necessary to determine safety in the context of COVID-19. We sought to determine the association between use of ACEI/ARBs and COVID-19 severity in patients with essential hypertension.

Dural involvement in central nervous system langerhans cells histiocytosis (LCH) on FDG PET/CT: Case report and review of CNS manifestations of LCH on PET/CT.

We report a case of multisystem Langerhans cell histiocytosis in a pediatric patient with central nervous system involvement, highlighting F-18(FDG) uptake characteristics of dural sites of disease. We also highlight the advantages of functional data offered by FDG-PET as a useful follow-up tool to assess viability and, therefore, treatment response of previously known central nervous system lesions. The utility of recognizing characteristic patterns of FDG uptake in dural disease is also applicable in cases of diagnostic uncertainty, such as when evaluating isolated dural lesions or when distinguishing between Langerhans cell histiocytosis and similar appearing lesions such as meningiomas.

Breast Mucocele-like lesions (MLL): A case report and review of the literature.

Mucocele-like lesions of the breast are rare, usually presenting themselves as suspicious findings on imaging, warranting biopsies. It can be associated with several degrees of hyperplasia, including atypical ductal hyperplasia and ductal carcinoma in situ, historically being considered a high-risk lesion. It also can be an underestimated invasive carcinoma in a percutaneous biopsy.
