A Rare Case of Paraneoplastic Syndrome of Inappropriate Secretion of Antidiuretic Hormone in Cervical Squamous Cell Carcinoma; A Case Report nd Literature Review.

SIADH is more commonly associated with small cell lung cancer but has also been associated with other malignancies such as oropharyngeal, gastrointestinal, genitourinary, endocrine, lymphomas, and sarcomas. There have been few reports of small cell carcinoma of the cervix complicated by SIADH; however, not many cases are associated with squamous cell carcinoma of the cervix. We present a case of a patient with squamous cell carcinoma of the cervix with a paraneoplastic syndrome of inappropriate secretion of antidiuretic hormone.

A Case of Multifactorial Viral Myocarditis.

We present a case of viral myocarditis in the setting of Coxsackievirus and coronavirus disease 2019 (COVID-19) infection. This case is unique as there were two underlying active infections that could have caused the patient's myocarditis. Though both viruses have been shown to cause myocarditis, it was difficult to differentiate the exact etiology in this particular case.

COVID-19 Presenting as Acute Bilateral Submassive Pulmonary Embolism in a Young Healthy Female.

Similar symptoms, signs, and laboratory abnormalities between coronavirus disease 2019 (COVID-19) and pulmonary embolism (PE) creates a diagnostic challenge to every physician, and emerging data show an association between COVID-19, hypercoagulable state, and venous thromboembolism. We present a rare case of COVID-19 presented as bilateral sub-massive PE. A 28-year-old COVID-19 positive female with no significant past medical history presented with a dry cough and shortness of breath for three days.
