A rare pulmonary hamartoma: fibroleiomyomatous hamartoma
Pulmonary hamartomas are more common than expected because they are usually asymptomatic and are either discovered on routine chest radiography or when they are noted incidentally in approximately 0.25 % of autopsies. In contrast, pulmonary fibroleiomyomatous hamartoma, which consists of interlacing bundles of smooth muscle cells admixed with fibrous tissue and numerous tubular or cleft-like ep...
متن کاملGiant pulmonary hamartoma
Pulmonary hamartomas are usually an incidental finding and range in size from 1 cm to 8 cm in diameter in various series. We report a case of a massive pulmonary hamartoma (size 25.5 x 17.5 x 6.5 cm and weighing 1134 g) in a 61 year old male who presented with a short history of breathlessness. The tumour was arising from the medial border of the right lung and occupying most of the right chest...
متن کاملPulmonary hamartoma syndrome.
We reviewed 24 charts of patients with pulmonary hamartoma; numerous congenital anomalies and benign tumors were observed in this series. Most of the observed associations are known to occur in patients with Cowden's syndrome, which is characterized by multiple hamartomatous neoplasms of ectodermal, mesodermal, and endodermal origin; however, to our knowledge, there has been no reported associa...
متن کاملMultiple Pulmonary Chondroid Hamartoma
A 30-year-old male was admitted to our hospital for a 3-month history of cough. The computed tomography (CT) scan of chest revealed multiple lesions with sporadic calcification (popcorn calcification) in the upper and middle lobes of the right lung (Fig. 1). A presumptive diagnosis of chondroid hamartoma was made according to the CT-guided percutaneous biopsy. Systemic positron emission tomogra...
متن کاملUltrastructural study of pulmonary bleomycin toxicity.
Ultrastructural manifestations of bleomycin A2 toxicity in the human lung were studied in three patients. In addition to the appearance of nucleolar fibrillar centers, an increase in membranous, beaded, and granular nuclear bodies was found in nuclei of type 1, type 2 alveolar epithelial cells, and interstitial fibroblasts in all treated patients. Few such nuclear bodies were found in specimens...
