Abstract
- The lymphoid system of the lung represents a complex network of lymphoid tissue and lymphatic vessels. Lymph nodes are normally located in the hila, adjacent to the lobar bronchi and within the lung to the level of the fourth-order bronchi. Clinically apparent intrapulmonary lymph nodes are rare. Although their histogenesis is uncertain, intrapulmonary lymph nodes are probably hyperplastic lymphoid nodules related to inhalation of irritant dusts and attendant distortion of local lymphatic vessels. Intrapulmonary lymph nodes are detected as solitary or multiple pulmonary nodules. These nodules are difficult to differentiate from intrapulmonary metastasis by radiologic finding. We experienced a case of intrapulmonary lymph nodes presenting multiple nodules in a 46 years old man, which was confirmed by thoracoscopic biopsy.
