Background
Pulmonary nodular lymphoid hyperplasia (PNLH) is a rare benign illness. Due to atypical clinical and radiographic presentations, diagnosis largely depends on postoperative pathological examination. Thus, preoperative misdiagnosis is often occurred.
Case presentation
We present a case of asymptomatic PNLH that was seen as ground-glass op...

... man was transferred from a local hospital after undergoing a routine health examination. He was healthy with no obvious discomfort, and he had 40 pack years smoking history. The initial chest CT scan performed in July 2017 revealed a GGO measuring up to 1.6 cm in maximum diameter and 2.14 cm 3 in volume in the lower lobe of the left lung (Fig. 1a). The GGO was multifocal, suggesting that it was ...Context 2

Pulmonary hemangiomas are benign, relatively rare tumours. Because computed tomography (CT) findings show a variety of images, it is often difficult to distinguish hemangiomas from lung cancer and other benign tumours. We report a 63-year-old man who was diagnosed with a pulmonary capillary hemangioma (PCH). A right lung basal segmentectomy was per...

A female in her 50s with right breast cancer was noted to have multiple ground-glass nodules in the bilateral lungs on chest computed tomography (CT), and so was referred to our hospital for biopsy. Bronchoscopic biopsy of the lung nodules failed to provide a diagnosis, so she underwent left S3 segmentectomy for excisional biopsy. The pathological diagnosis was pulmonary nodular lymphoid hyperplasia (PNLH) with no evidence of malignancy. Subsequently, she received right mastectomy and adjuvant chemotherapy for breast cancer. Chest CT at 6 months after the operation for the breast cancer showed regression of the remaining ground-glass nodules. PNLH is a rare condition and its natural history remains unclear, so we are planning to continuously follow-up the patient.
