A case of symptomatic cervical adenopathy is reported as a presentation of silicosis. Silicosis is one of the most important occupational health diseases worldwide caused by the inhalation of airborne silica particles. The presence of thoracic adenopathies is a common clinical feature of silicosis, cervical silicotic adenopathies on the other hand are rare and unknown to most clinicians and can therefore lead to a differential diagnostic problem. Awareness of the clinical, radiological, and histological features is key for the diagnosis.

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 inflammation. The adventitial stroma of the pulmonary artery developed into dense and borderless fibrous tissue with dust-laden macrophages.
CONCLUSIONS
Our pathological findings on lymph node anthracosilicosis provide substantial evidence that adhesions between lymph nodes and the pulmonary artery walls may develop into dense and borderless fibrous tissue. This finding would remind thoracic surgeons that adhesiolysis could cause injury to the pulmonary artery.
