Nerve sheath myxoma (NSM) is a rare benign peripheral nerve sheath tumor that affects young adults. NSMs are asymptomatic, slow-growing swellings located in the upper extremities, more rarely in the lower extremities. Given the high risk of recurrence, it is recommended to perform a complete exeresis. To our knowledge, the evolution and management of NMS during pregnancy have not been described yet. We report the first case of recurrent pretibial NSM in a pregnant girl and its follow-up and outcome during and after pregnancy. NSM is difficult to diagnose clinically or using imaging. The final diagnosis remains histopathological. It is known how various types of benign and malignant skin tumors can develop or change during pregnancy. With our case, however, we documented that pregnancy does not affect the growth and evolution of NSM. Given the benign nature of the lesions and their tendency to grow slowly, during pregnancy, follow-up of NSMs can be conducted through ultrasonography and surgical treatment postponed after delivery. Our case highlights the importance of careful monitoring and individualized decision making, especially in rare scenarios such as NSM, where data on the progression of benign lesions are limited. Our case highlights the importance of a careful monitoring and a tailored treatment in rare scenarios such as NSM, where data on the progression of benign lesions are limited. Considering the benign nature of the lesions and their tendency to grow slowly, follow-up of NSMs during pregnancy can be conducted through ultrasonography, and surgical treatment can be postponed after delivery.

More than 50 years after its introduction in clinical practice, the increase in the intensity of care offered by the cardiac intensive care units, the shift in the population of patients treated and the wider availability of circulatory supports, still makes the pulmonary artery catheter (PAC) an essential tool for diagnosis, monitoring and prognosis in patients suffering from cardiogenic shock. In this review, we will discuss how to identify those patients who can benefit most from its use, the configuration and the correct insertion technique of a PAC. A pragmatic guide will also be provided for the interpretation of the hemodynamic indexes (direct and calculated) that the PAC is able to reveal as well as a summary of the most common errors in reading or interpreting the pressure curves provided by the PAC. In this article, we will then present a practical guide on how to use the PAC in a modern cardiac intensive care unit.
