Pulmonary Hamartoma, an Enlarging Neoplasm

The Histological Classification of Lower Respiratory Tract Tumours

“…These latter terms were introduced by Albrecht (1904) to designate tumours arising from tissues, normally present in the organ, which have failed to grow along normal architectural lines, " hamartomas " being non-neoplastic malformations and " hamartoblastomas " those showing neoplastic growth. Brewer, Brookes and Valteris (1953) demonstrated that these mesenchymal lung tumours were true neoplasms, without the presence of a developmental anomaly, and this was later confirmed by Weisel, Glicklich and Landis (1955) and by Adams (1957). Willis (1958) Brewin (1953) and confirmed in a leiomyoma and an osteochondroma of the present series.…”

Cartilage-containing tumours of the lung: Relationship between the purely cartilaginous type (chondroma) and the mixed type (so-called hamartoma): an unusual case of multiple tumours

“…The presence of epithelial-celllined spaces within the majority of these tumours results from the inclusion of the epithelium lining the bronchus of origin by the lobular and eccentric growth of the cartilage and connective tissue into the lumen of the bronchus (Bateson, 1965). The absence of epithelial-cell-lined spaces in three of the four tumours in the present case and in those reported by Bikfalvi et al (1954), Edling (1938, Franco (1958), Hodges (1958), Kirschner and Kny (1957), and Weisel et al (1955) can be explained by the proliferation of the connective tissue and the formation of cartilage with expansion of the tumour outside the bronchus into the adjacent lung parenchyma.…”

“…Examples of tumours of this type have been reported by Bikfalvi, Molnar, and Horanyi (case 8, 1954), Edling (1938), Franco (1958), Hodges (1958), Kirschner and Kny (case 6, 1957), and probably case 3 in the series reported by Weisel, Glicklich, and Landis (1955).…”

Relationship Between Intrapulmonary and Endobronchial Cartilage-containing Tumours (so-called Hamartomata)

“…However, cases of intrapulmonary cartilage-containing tumours attached to the external wall of a small bronchus have been reported by Franco (1958), Negre, Martin, and Loubatieres (1954), Nigam (1957), Novi (1955), Rubin and Berkman (1952), Sherrick (1952), Stein andPoppel (1955), and Weisel, Glicklich and Landis (1955). A few intrapulmonary cartilagecontaining tumours with a small bronchus entering their substance have been reported by Favre (1935), Mammer (1927, and Moller (1933).…”
