Osteochondroma, often referred to as exostosis, is the most common benign bone tumor characterized by a bony protuberance surrounded by a cartilaginous surface. Most osteochondromas are found on the metaphysis of long bones, with the dorsal aspect of the scapula being a rare site of occurrence for an exostosis. Radiographic imaging, preferably through MRI or CT, assists in the identification of benign growth; however, a definitive diagnosis requires a biopsy. Open surgical resection and arthroscopic excision are the definitive treatment modalities of the nidus. Postoperative care requires immobilization of the limb for two months, with at least four months being the appropriate timeline for complete recovery.

COVID-19, which is caused by the novel severe acute respiratory syndrome coronavirus (SARS-CoV-2), is known to cause a myriad of complications along with the typical lower respiratory tract involvement. One of the emerging complications is a hypercoagulable state leading to venous or arterial thromboembolism. These complications are more common in those presenting with a severe disease with significantly elevated inflammatory markers. Although co-morbid illnesses play a role in worsening such complications, yet they are not the main determinants as these complications also occur in those without any co-morbid illness.Here, we report a case of a 64-year-old male with severe COVID-19 pneumonia presenting with acute limb ischemia with a non-salvageable limb who required subsequent amputation of the affected limb.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is best known for causing febrile pneumonia with lung parenchymal involvement. However, that is often not the only disease presentation, as many studies have shown that coronavirus disease 2019 (COVID-19) can present with other complications involving the cardiovascular and neurologic systems. Here, we report a case of COVID-19 pneumonia presenting with a peculiar finding of unilateral diaphragmatic paralysis. The patient presented with dyspnea requiring oxygen support via a nasal cannula. He was managed with the hospital's COVID-19 treatment protocols and clinically improved within 14 days of admission. This case helps shine some light on the neuroinvasive potential of SARS-CoV-2.

A neurofibroma is a benign, non-encapsulated neoplasm of the peripheral nerve sheath. These tumors are a notorious manifestation of the autosomal dominant condition known as neurofibromatosis type 1, where they present as multiple, cutaneous masses with high malignant potential. On the contrary, benign solitary retroperitoneal neurofibromas (SRN) occur without any associated conditions and have rarely been documented. Our case is of a 40-year-old male who presented with a three-month history of painful calf swelling, refractory to over-the-counter painkillers which was later diagnosed as deep vein thrombosis (DVT). A computed tomography (CT) angiogram was done which revealed a mass in the retroperitoneum impinging on the inferior vena cava (IVC). Approximately one month later, the whole mass was surgically excised and histopathology confirmed the diagnosis of a neurofibroma. This case presentation proved to be novel as it highlights the evaluation and management of a rare SRN which resulted in extensive DVT.
