Giant Pulmonary Hamartoma—A Rare Presentation of a Common Tumor

Pulmonary hamartoma treated by thoracoscopic enucleation

“…1 Slow growth is usual for these tumors, with an observed increase of 3.2 ± 2.6 mm per year. 2 The mean size of hamartomas is 1.5 cm (range 0.2-6.0 cm), and no lobe is predominantly involved. 1 There are some reports of giant symptomatic hamartomas.…”

“…1 There are some reports of giant symptomatic hamartomas. 2,3 Hamartomas, the third most common solitary pulmonary nodule following granuloma and carcinoma, usually account for 6%-8% of localized parenchymal masses treated by thoracotomy. 4 Although evaluation of the specifi c morphological features (e.g., size, margins, contour, internal characteristics) of a solitary pulmonary nodule with conventional imaging techniques can help us differentiate pulmonary hamartoma from others (e.g., neoplastic, infl ammatory, vascular, and congenital causes), initial evaluation often results in nonspecifi c fi ndings, and the nodules are classifi ed as indeterminate.…”

Giant Pulmonary Chondroid Hamartoma

“…Chondroid hamartomas of the lung are the most common benign pulmonary neoplasms. 1 They represent disorganized growth of normal lung tissues including cartilage, fat, bronchial-type epithelium, smooth muscle, and fibrous tissue. 2 They are usually small with an average diameter of 2 cm and almost always asymptomatic, incidentally discovered lesions.…”

“…3 Pulmonary chondroid hamartomas (PCHs) measuring over 10 cm are extremely rare and sometimes symptomatic. 1,[3][4][5][6] With radiographic and CT imaging, PCH has been characteristically described as a well-circumscribed pulmonary nodule containing irregular nodular calcifications known as "popcorn" calcifications and foci of radiographically evident fat. 7 However, FDG PET imaging features of PCH are less well known.…”

Riesiges Hamartom der Lunge

“…Über Hamartome mit Riesencharakter wurde in einzelnen Kasuistiken berichtet [4,6,8,9]. Diese Riesenhamartome können als extrapulmonale Tumoren imponieren.…”
