BACKGROUND
The majority of tracheal tumors in adults are malignant. The finding of a benign tumor in the trachea is uncommon and endotracheal hamartomas are rare.
METHODS
We report two cases presenting within six months at our institution. The first patient is a 67 year-old man who was found to have
This prospective study includes 103 cases of chondroid pulmonary hamartomas, resected over a period of nearly six years. Genes encoding proteins of the high motility group (HMGI-C, (Y), chromosomes 12q15 and 6p21) were analyzed cytogenetically. Furthermore, we examined the expression of
Polymorphic glutathione-S-transferase (GST) genes causing variations in enzyme activity may influence individual susceptibility to lung cancer. In this case-control study (consisting of 389 Caucasian lung cancer patients, including 151 adenocarcinomas (ACs) and 172 squamous cell carcinomas (SCCs),
BACKGROUND
Pulmonary hamartoma is the most common type of benign lung tumors. We retrospectively reviewed the clinicopathological features of 61 patients with pulmonary hamartomas undergoing surgical resection in our institution.
METHODS
From 1971 to 2002, 61 patients with 62 pulmonary hamartomas
Approximately one out of 500 chest radiographs shows the incidental finding of a solitary pulmonary nodule and almost one half of these pulmonary lesions are caused by a tumor. Unfortunately, only 2% to 5% of all lung tumors are of benign origin, e. g. lipoma, fibroma, hamartoma, and chondroma, and
BACKGROUND
Lymphangioleiomyomatosis (LAM) is a rare disease that predominantly affects young females. It is considered as an "orphan" life-threatening disease of unknown etiology, with uncertain clinical prognosis, and no effective treatment. LAM can arise sporadically or in association with
Lkb1 is a central regulator of cell polarity and energy metabolism through its capacity to activate the AMP-activated protein kinase (AMPK)-related family of protein kinases. Germ line-inactivating mutation of Lkb1 leads to Peutz-Jeghers syndrome, which is characterized by benign hamartomas and a
