The COVID-19 pandemic has led to many discoveries and clinical manifestations. A young patient is presented with new, self-resolving neutropenia presenting weeks after a prolonged hospital stay for COVID-19 pneumonia. Workup included analysis for underlying infection, nutritional abnormalities, malignancy, medication and toxin exposure, all of which were negative. From 2020 to the present, few reports have described neutropenia associated with a recent COVID-19 infection. In particular, no reports have described a delayed presentation of neutropenia. The authors would like to propose that the significant inflammatory response associated with COVID-19 is likely what led to this patient\u2019s postviral neutropenia. Furthermore, in young healthy patients, bone marrow biopsy may be deferred and a watchful-waiting approach may be taken to assess for neutropenia resolution.<\/jats:p>","DOI":"10.1136\/bcr-2021-242596","type":"journal-article","created":{"date-parts":[[2021,5,12]],"date-time":"2021-05-12T13:14:54Z","timestamp":1620825294000},"page":"e242596","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":17,"title":["Delayed,
