Suspected Aspergillus nodule histologically consistent with pulmonary nodular lymphoid hyperplasia:a case report
J Med Invest. 2023;70(3.4):499-502. doi: 10.2152/jmi.70.499.ABSTRACTAspergillus nodules (AN) are an unusual form of chronic pulmonary aspergillosis. On the other hand, pulmonary nodular lymphoid hyperplasia (PNLH) is classified as a reactive pulmonary lymphoproliferative disorder. A 65-year-old male was referred to our hospital due to a nodule in the left upper lobe. Histologically, a mixture of prominent lymphoid follicular formation, and hyaline necrosis were observed. Grocott staining revealed morphological forms of Aspergillus spp. in the necrosis. The final clinical diagnosis was suspected AN histologically consistent with PNLH. This case suggests that there may be PNLH cases in which local infection with Aspergillus contributes to its pathophysiology. J. Med.
