Lung cancer at its earliest stage is typically manifested on computed tomography as a pulmonary nodule, which could be detected by low-dose multidetector computed tomography technology and the use of thinner collimation. Within the last 2 decades, computer-aided detection (CAD) of pulmonary nodules has been developed to meet the increasing demand for lung cancer screening computed tomography with a larger set of images per scan. This review introduced the basic techniques and then summarized the up-to-date applications of CAD systems in clinical and research programs and in the low-dose lung cancer screening trials, especially in the detection of small pulmonary nodules and missed lung cancers...

INTRODUCTION: Computed tomographic pulmonary angiograms (CTPAs) are often ordered to evaluate pulmonary embolism (PE) in the emergency department (ED). The increase use of CTPA has led to an increase in incidental findings, often of low clinical significance. Our objectives were to (1) assess the prevalence and clinical significance of incidental findings identified in patients evaluated with CTPAs for PE in the ED, (2) evaluate follow-up investigations for these incidental findings, and (3) assess the utility of routine chest X-rays done prior to CTPA...

The galaxy sign and cluster sign were first reported in pulmonary sarcoidosis. From those reports, these two signs became known as one of the characteristic computed tomography (CT) findings of sarcoidosis. We report a patient with pulmonary tuberculosis who had these two signs. A 44-year-old man was referred to our hospital for general fatigue, cough, and low-grade fever lasting about two months. Thoracic CT showed a large parenchymal nodule arising from coalescent small nodules (galaxy sign) and clusters composed of numerous small nodules (cluster sign) in the bilateral lungs...

A 62-year old man with severe chronic obstructive pulmonary disease developed a persistent air leak from an iatrogenic pneumothorax following Computed Tomography-guided core biopsy of a pulmonary nodule. The pneumothorax was treated with an 8.5F intercostal catheter, which was then replaced by a 28F thoracostomy tube after development of significant subcutaneous emphysema and a tension pneumothorax. The air leak showed no improvement until endobronchial valve (EBV) insertion guided by objective flow data from a digital drainage system (DDS)...

PURPOSE: Uniportal video-assisted thoracoscopic surgery (VATS) has recently been reported as an alternative to conventional VATS. However, preoperative image-guided localization is usually required for small nodules. The present study evaluated the efficacy of preoperative computed tomography-guided dye localization prior to uniportal VATS for small undetermined pulmonary nodules. METHODS: We retrospectively reviewed 298 consecutive patients who underwent uniportal VATS to treat undetermined pulmonary nodules (diameter ≤ 1...

RATIONALE: Familial hydatidiform mole is extremely rare while familial gestational trophoblastic neoplasia (GTN) has never been reported. Inspired by 2 biological sisters with postmolar GTN and liver toxicity, we reviewed susceptible maternal-effect genes and explored the role of possible drug transporter genes in the development of GTN. PATIENT CONCERNS: We reported one Chinese family where the two sisters developed postmolar GTN while experiencing fast remission and significant hepatic toxicity from actinomycin D chemotherapy...

H C Jo, J C Baek
Benign metastasizing leiomyoma (BML) is a rare tumor comprising histologically benign smooth muscle cells and exhibits the same histological findings as a uterine myoma although in an extra-uterine location. Most BMLs occur several years after surgery for uterine myoma in women of reproductive age. Here, we report a case of pulmonary BML in a 54-year-old postmenopausal woman with no previous history of myomectomy or hysterectomy. The patient presented with a rapid increase in abdominal girth over the past 3 months and a cough lasting for 2 months...

REVIEW
Yoshihisa Kobayashi, Chiara Ambrogio, Tetsuya Mitsudomi
Pulmonary ground-glass nodules (GGNs) are hazy radiological findings on computed tomography (CT). GGNs are detected more often in never-smokers. Retrospective and prospective studies have revealed that approximately 20% of pure GGNs and 40% of part-solid GGNs gradually grow or increase their solid components, whereas others remain stable for years. Most persistent or growing GGNs are lung adenocarcinomas or their preinvasive lesions. To distinguish GGNs with growth from those without growth, GGNs should be followed for at least 5 years...

Erythroderma is occasionally associated with lung cancer. Here we report a 69-year-old male who has history of melanoma from 8 years ago presented with erythroderma associated with skin, soft tissue and pulmonary infection. CT chest showed a single enlarging right upper lobe lung nodule. Biopsy showed evidence of adenocarcinoma, and eventually proven to be metastatic melanoma. The patient improved after antibiotics and antifungal treatment. To our knowledge, this is the first case of melanoma metastasis presented as erythroderma as paraneoplastic syndrome...

Situs inversus totalis is a rare clinical condition that represents a complete mirror image of the normal arrangement of the thoracic and abdominal viscera. There are very few reported cases of lung cancer patients with situs inversus totalis, but this condition requires particular care during surgery. A 61-year-old woman presented to our hospital with an abnormal shadow on chest radiography. Computed tomography revealed a 25×12 mm solitary pulmonary nodule in the left upper lobe (S2) and a complete mirror image of the normal organ arrangement, which findings met the criteria of situs inversus totalis...

BACKGROUND: Platelet glycoprotein Ibα (GPIbα) extracellular domain, which is part of the receptor complex GPIb-IX-V, plays an important role in tumor metastasis. However, the mechanism through which GPIbα participates in the metastatic process remains unclear. In addition, potential bleeding complication remains an obstacle for the clinical use of anti-platelet agents in cancer therapy. METHODS: We established a series of screening models and obtained rat anti-mouse GPIbα monoclonal antibodies (mAb) 1D12 and 2B4 that demonstrated potential value in suppressing cancer metastasis...

Lymphangioleiomyomatosis (LAM) is a rare disease that generally affects young women and involves the abnormal proliferation of smooth muscle-like cells (LAM cells) in the lungs (pulmonary LAM) and extrapulmonary sites (extrapulmonary LAM). This disease is rare in males. It is hard to distinguish between lung cancer and pulmonary LAM, especially during early stages. Herein, we present a case of a 66-year-old man with a small nodule in the right upper lobe that was first diagnosed as a lung malignancy using a chest CT scan...
