Microscopic feature of lymph node anthracosilicosis adherent with pulmonary artery: a case report

ABSTRACT:

Background

Although thoracic surgeons occasionally encounter dense adhesions of interlobar lymph node anthracosilicosis with the pulmonary artery, adhesiolysis may be challenging. Besides, characteristic microscopic features of the adherent lesion remain limited.

Case presentation

During a thoracoscopic right upper lobectomy of a patient with stage IA3 primary lung adenocarcinoma, several interlobar lymph nodes adhered to the posterior ascending branch of the pulmonary artery to the right upper lobe were noted. After an unplanned conversion to a thoracotomy to avoid massive bleeding, the pulmonary artery branch was safely isolated. Microscopic examination revealed lymph node anthracosilicosis proximal to the peripheral pulmonary artery wall, with granulomatous inflammatio
