Abstract

COVID-19, which infects millions of people worldwide, can affect many organs and systems, mainly
lungs, heart, brain, kidneys, vascular endothelium and bone marrow. As a result; it causes a wide
range of complications such as ARDS, acute coronary syndrome, delirium, pancytopenia, DIC, kidney
damage. Therefore, in the presence of COVID-19, some diseases that progress rapidly and which can
cause similar complications may be concealed. In our article, we’re going to tell a patient who was
missed due to the adverse effects of the pandemic period and because the COVID-19 infection may
cause similar findings, although he admitted to emergency clinique twice before. In a pancytopenic
patient suffering from intermittent fever, exhaustion, myalgia and arthralgia for several months, the
diagnosis of small cell lung cancer, bone marrow metastasis and Lambert Eaton Myasthenic Syndrome
(LEMS) was delayed due to the presence of COVID-19 infection. Therefore, the patient died in a short
time. It was presented because it is a rare case and can lead to serious consequences if not imagined..
