Abstract Fifty consecutive human autopsy specimens were studied to determine the suitability of the superficial temporal artery (STA) for use in microvascular anastomoses. Ten variations of the STA were found. The STA at the zygoma averaged 2.2 mm in outside diameter. The STA averaged 31.7 mm from the zygoma to its bifurcation, where the average outside diameter was 1.9 mm. Eight per cent of the specimens had no bifurcation, and 92% had at least one branch in a frontal or parietal distribution that was ≥1 mm. A suitable frontal branch (i.e., ≥1 mm in diameter and ≥70 mm in length) was found in 90% of the specimens, and a suitable parietal branch was found in 71%. Six specimens (12%) had an additional branch, all of which were of suitable length and diameter. Eight per cent of the specimens lacked a vessel suitable for microvascular anastomosis.

ABSTRACTAlthough COVID-19 causes cardiac dysfunction in up to 25% of patients, its pathogenesis remains unclear. Exposure of human iPSC-derived heart cells to SARS-CoV-2 revealed productive infection and robust transcriptomic and morphological signatures of damage, particularly in cardiomyocytes. Transcriptomic disruption of structural proteins corroborated adverse morphologic features, which included a distinct pattern of myofibrillar fragmentation and numerous iPSC-cardiomyocytes lacking nuclear DNA. Human autopsy specimens from COVID-19 patients displayed similar sarcomeric disruption, as well as cardiomyocytes without DNA staining. These striking cytopathic features provide new insights into SARS-CoV-2 induced cardiac damage, offer a platform for discovery of potential therapeutics, and raise serious concerns about the long-term consequences of COVID-19.

Pseudomyogenic hemangioendothelioma (PMH) is a rare vascular tumor that presents more frequently in young adults and has a male predominance. It is usually located in the superficial or deep soft tissues of the extremities, but concurrent bone involvement can be present. In approximately two-thirds of patients this disease is multifocal, often involving multiple tissue planes. It is a relapsing lesion with low metastatic potential. Given its clinical and morphologic characteristics (multifocality, epithelioid morphology, absence of clearly evident vascular differentiation on hematoxylin-eosin slides), PMH can be easily misinterpreted as other lesions, often with radically different treatment and prognosis. For this reason, we think it is important to recognize this entity, which has some unique features. Here, we will briefly describe the clinical and pathologic features of PMH, detailing its more relevant differential diagnoses.
