B-Cell Lymphoma Associated with COVID-19 Infection: A Case Report.

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.
