Three-dimensional visualization of an unusual pulmonary lymphoproliferation after COVID-19

The following case report details the case of a 40-year-old Caucasian patient who presented with dyspnea following a serologically confirmed mild-to-severe pulmonary infection with SARS-CoV-2. Chest computer tomography revealed a solitary ground-glass pulmonary nodule in the lower right lobe, measuring 2.1 cm in diameter. Video-assisted thoracoscopic surgery wedge resection revealed well-circumscribed lymphoid aggregates adjacent to the round, smaller airways, bronchioles, and blood vessels. IgKappa B exhibited a monoclonal polyclonal pattern, in contrast to the behavior exhibited by IgKappa A and IgLambda. In the following discussion, the lymphoid lesion was considered in the context of lymphoid hyperplasia, accompanied by an early infiltration of low-grade extranodal B cell lymphoma of the bronchus-associated lymphoid tissue (BALToma).

Abstract

The following case report details the case of a 40-year-old Caucasian patient who presented with dyspnea following a serologically confirmed mild-to-severe pulmonary infection with SARS-CoV-2. Chest computer tomography revealed a solitary ground-glass pulmonary nodule in the lower right lobe, measuring 2.1 cm in diameter. Video-assisted thoracoscopic surgery wedge resection revealed well-circumscribed lymphoid aggregates adjacent to the round, smaller airways, bronchioles, and blood vessels. IgKappa B exhibited a monoclonal polyclonal pattern, in contrast to the behavior exhibited by IgKappa A and IgLambda. In the following discussion, the lymphoid lesion was considered in the context of lymphoid hyperplasia, accompanied by an early infiltration of low-grade extranodal B cell lymphoma of the bronchus-associated lymphoid tissue (BALToma).
