A Rare Case of Acquired Bleeding Disorder in a 24-Year-Old Hispanic Female.

Vitamin K is a fat-soluble vitamin that has a major role in coagulation pathways thus its deficiency can lead to major bleeding disorders. Vitamin K deficiency in an otherwise healthy adult is rare. Inadequate oral intake of vitamin K remains the most common cause of vitamin K deficiency. Here, we report a young female who presented for evaluation of heavy menstrual bleeding and was found to be deficient in vitamin K-dependent coagulation factors, with correction upon mixing study. She was diagnosed with vitamin K deficiency due to poor oral intake. With this case, we report a rare and avertible cause of major bleeding to raise awareness among clinicians about patients' daily nutritional requirements.

A Case Report of DVT following the Johnson and Johnson Vaccine against the Novel SARS-CoV-2.

Deep vein thrombosis (DVT) is the formation of a blood clot typically in the deep veins of the extremities. The risk factors for venous thrombosis are primarily related to hypercoagulability, which can be genetic, acquired, or due to immobilization and venous stasis. The Johnson and Johnson (J&J) vaccine developed against the novel SARS-CoV-2 has been linked to more specific cases of thrombosis, associated with low platelet levels similar to that seen in heparin-induced thrombocytopenia. In this case report, we present a female who developed a DVT four days after receiving the J&J vaccine. We propose that the administration of this vaccine may further increase the risk of developing DVTs in patients with previous risk factors, and we hope to use this case to support screening all patients for previous risk factors for thrombosis before administration of the J&J vaccine.

Management of Newly Diagnosed Chronic Myeloid Leukemia During COVID-19 Hospitalization: A Teaching Case.

Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm characterized by the dysregulated production and uncontrolled proliferation of mature and maturing granulocytes. CML has the potential to cause secondary immunodeficiency in affected patients. COVID-19 infection has been associated with worse outcomes in immunocompromised patients, including patients with hematologic cancers, requiring hospitalization. Herein we present a 61-year-old male with known COVID-19 infection who presented for the evaluation of acute hypoxic respiratory failure and was found to have marked leukocytosis of 125,000. The patient was eventually diagnosed with CML, and his respiratory failure resolved with conventional COVID-19 pneumonia treatment. With this case report, we hope to assist clinicians in the workup of marked leukocytosis in the setting of COVID-19 pneumonia and aim to help clinicians in the management of patients admitted with COVID-19 pneumonia and concomitant CML.

It smells and tastes like cancer but it's not cancer: A case report of aggressive benign lung neoplasm.

Desmoid tumors are rare, locally aggressive benign tumors with a high rate of recurrence even after complete resection. Only twenty percent are intrathoracic and they are often painless or minimally painful with slow growth. Rarely they can grow quite rapidly, mimicking a malignant tumor. Here we present a rare case of a rapidly growing, intrathoracic desmoid tumor mimicking lung malignancy in an elderly male ex-smoker. This case demonstrates the importance of including desmoid tumors in the differential diagnosis of lung masses, raising awareness of benign tumors mimicking malignant behavior, and emphasizing the potential benefit of timely follow-up and early diagnosis.
