[A hard subcutaneous swelling: not always as malignant as it seems].

Background: Nodular fasciitis is a rare, benign soft tissue tumor in young adults on the arms or trunk.

Case Description: A 24-year-old woman with previous pretibial melanoma in situ presented with a painless, rapidly growing subcutaneous hard swelling on the right forearm since two weeks. Ultrasound showed a subcutaneous, irregularly shaped, vascularized mass, suspicious for malignancy.

[A man with Covid-19 and abdominal pain].

A 53-year-old man, diagnosed with Covid19, experienced pain in the left flank. Imaging results showed multiple spleen infarction. While thrombotic events are common complications in Covid19, diagnosing and imaging a spleen infarction is rather rare.

Impact of hernia volume on pulmonary complications following complex hernia repair.

Background: Despite a multitude of evidence-based prediction models and risk factors for postoperative complications after ventral hernia repair, estimating a patient's risk of postoperative complications after ventral hernia repair remains challenging. In an attempt to improve the preoperative assessment of complex hernia patients, some studies have examined pulmonary changes after hernia repair hypothesizing that large hernias lead to pulmonary changes and increased pulmonary complication rates. Some studies have described a correlation between hernia volume and pulmonary changes, although none provided compelling evidence to identify hernia volume as a risk factor for pulmonary complications.

Malformations of the axial skeleton in the museum Vrolik: II: craniosynostoses and suture-related conditions.

The Museum Vrolik collection of anatomical specimens in Amsterdam, The Netherlands, comprises over 5,000 specimens of human and animal anatomy, embryology, pathology, and congenital anomalies. Recently, we rediagnosed a subset of the collection comprising dried infantile, juvenile, and adult human skulls with congenital and acquired conditions. On external examination and additional radiography, we found 58 skulls with craniosynostosis (CS) involving one or more sutures and 40 skulls with a presumed suture related condition.
