Sinonasal leiomyosarcoma (LMS) is a rare and aggressive mesenchymal tumor with smooth muscle differentiation. The sinonasal tract is an unusual primary site for LMS, as scant smooth muscle exists in this location, with only 75 cases reported in the English literature including the case presented herein. Sinonasal LMS is considered an aggressive head and neck tumor with significant potential for recurrence and metastasis. Since recurrence is high and the potential for late metastasis exists, lifelong follow-up in these patients would be beneficial, especially among those with previous history of RB.

Background And Aims: Aortic dissection (AD) is one of the most dangerous and tricky diseases in the field of cardiovascular surgery, severely affecting public health. Recent studies have found that SUMOylation is linked to the pathogenesis of cardiovascular diseases. However, we know very little about the molecular mechanisms of SUMOylation in AD.

Lymphangioleiomyomatosis (LAM) is a rare lung disease caused by hyperactivation of the mechanistic/mammalian target of rapamycin 1 (mTORC1) growth pathway in a subset of mesenchymal lung cells. Histopathologically, LAM lesions have been described as immature smooth muscle-like cells positive for the immature melanocytic marker HMB45/PMEL/gp100 and phosphorylated ribosomal protein S6 (pS6). Advances in single cell sequencing (scRNA-seq) technology allowed us to group LAM cells according to their expression of cancer stem cell (CSC) genes and identify three clusters: a high CSC-like state (SLS), an intermediate state, and a low CSC-like inflammatory state (IS).

In adult mammals and other highly developed animals, incomplete wound healing, scar formation, and fibrosis occur. No treatment for complete tissue regeneration is currently available. However, in mice, at up to 13 days of gestation, early embryonic wounds regenerate without visible scarring.

Resistance arteries, which include small arteries and arterioles, play essential roles in regulating blood pressure and tissue perfusion. Dysfunction in these arteries can lead to various cardiovascular conditions such as hypertension, atherosclerosis, and heart failure, as well as neurovascular conditions. The examination of human resistance arteries is crucial for understanding cardiovascular disease mechanisms and developing targeted therapeutic strategies.
