A case of benign sugar (clear) cell tumor of the lung with an unusual clinical presentation and its evaluation with computed tomography are reported. A 48-year-old man presented with one episode of hemoptysis. Chest radiographs revealed a round nodule in the lower left lung lobe, and fiberoptic bronchoscopy was normal. On the computed tomography scans, the nodule showed intense post-contrast enhancement (74.7 Hounsfield units). The patient underwent a left thoracotomy, and a segmentectomy was performed. Pathologic examination showed a benign sugar cell tumor of the lung. The patient is alive and has remained free of disease for the last 2 years. To the best of our knowledge, this is the first case report of sugar cell tumor located in lung parenchyma that presented with hemoptysis and the second report of the contrast-enhanced computed tomography findings in this neoplasm.

Presenting clinical characteristics of OSA are modulated by the population evaluated and may affect the performance of screening questionnaires.

PURPOSE:Gastroparesis is a post lung transplant (LTx) complication that can result from immunosuppression, vagal nerve injury, and underlying lung disease. We aimed to define the incidence, risk factors, and impact of gastroparesis following LTx.METHODS: Baseline characteristics of age, type of transplant, gender, and underlying disease of patients who underwent lung transplantation at our center between 1/1/12 and 1/1/17 were collected. Post-LTx outcomes including hospital length of stay, feeding tube placement, need for acute rehabilitation, and post-LTx survival were compared between those with and without gastroparesis.RESULTS: Of 116 LTx patients, 17 (15%) had gastroparesis after LTx. Females (58% vs. 25%, p=0.01), bilateral LTx recipients (63% vs 33%, OR 3.38; p=0.02) and cystic fibrosis (CF) patients (18% vs 3%, p=0.04) were more likely to have post LTx gastroparesis. The gastroparesis group required more gastrojejunostomy tubes (65% vs 1% p<0.001) with more days without oral intake (5.5 vs 0 p <0.001). There was a trend toward longer hospital length of stay (60 vs. 29 days), greater need for acute rehabilitation, and reduced survival (median of 27.2 months vs. undefined due to inadequate follow-up time, p=0.1) in patients with gastroparesis compared to those without. CONCLUSIONS:Post-LTx gastroparesis appears to be more common among women, CF patients and bilateral LTx recipients. It is associated with increased need for feeding tube placement, longer hospital length of stay, debility, and attenuated posttransplant survival.CLINICAL IMPLICATIONS: Gastroparesis after LTx is a risk factor for poor outcomes and should be diagnosed and treated aggressively. A thorough evaluation for gastroparesis should be performed prior to LTx with consideration of single lung procedure in high risk patients, where clinically appropriate.
