Purpose:
Most common publications are related to COVID-19 diagnosis in hematological malignancy patients. However, here we report a case involving a patient diagnosed with B-cell lymphoma while undergoing treatment for COVID-19, including the changes in major clinical symptoms and medical examinations, then explain the probable causes of the case.
Case Presentation:
A 74-year-old woman with a previous history of oesophageal cancer was admitted to the hospital after having cough and sputum for 15 days. Despite the COVID-19 symptoms, this patient did not have a fever at the time of the onset. Results of routine blood tests were normal at first but then declined with persistent fever, and A whole-body C.T. examination ruled out the possibility of tumor-metastasis-related fever. This patient had no hepatosplenomegaly or regional lymphadenopathy, and there was no concrete evidence of haemophagocytic lymphohistiocytosis or lymphoma until bone marrow biopsy results confirmed the latter.
Conclusion:
We describe an uncommon case of COVID-19 who was finally diagnosed with B-cell lymphoma. An awareness of persistent fever and declined routine blood tests caused by hematological malignancies instead of COVID-19 itself can aid in providing appropriate guidelines for management and treatment.
