Patients And Methods: The demographic and infection-related characteristics of patients who had been infected with COVID-19 were determined.

A Case of Esophageal Plasmablastic Lymphoma With a Literature Review.

Plasmablastic lymphoma is a rare B-cell lymphoma that is mainly associated with immunocompromised patients, such as those affected with human-immunodeficiency virus (HIV) or those who have received solid organ transplants; however, it has also been documented in immunocompetent patients. Moreover, there is also a strong association with Epstein-Barr virus (EBV). Although mainly found in the oral cavity, a few cases were documented to affect the gastrointestinal tract, and of those, only three cases were found to involve the esophagus, and we present the fourth case in a 48-year-old HIV-positive male.

Primary Combined Hepatocellular-Cholangiocarcinoma: A Case of Underdiagnosed Primary Liver Cancer.

Combined hepatocellular-cholangiocarcinoma (CHC) is a rare primary tumor of the liver. Histologically, it comprises components of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) but is associated with a worse prognosis. International guidelines regarding its management are scarce, with surgical management (major hepatectomy) being the treatment of choice.

A Rare Coexistence of Paraneoplastic Cerebellar Degeneration: Papillary Thyroid Carcinoma.

Paraneoplastic cerebellar degeneration (PCD) is a rare neuroimmunological disease that may accompany tumors. In this article, we present a patient with progressive gait difficulty who was diagnosed with PCD and, in a rare comorbidity, with papillary thyroid carcinoma (PTC) following malignancy screening. A 46-year-old male patient reported having experienced poor balance for 2 years.

An Unusual Recurrence of Miller Fisher Syndrome: Three Times in Eight Years.

Miller Fisher Syndrome (MFS) is an acute, autoimmune polyneuropathy usually associated with a good prognosis which is clinically characterized by ataxia, ophtalmoplegia, and areflexia. MFS has a monophasic course, double recurrence can be seen in rare cases. But three attacks are very rare.
