Cystic Adenomata of the Ventricles of Morgagni

Eosinophilic Granular-Cell Cystadenoma of the Larynx

“…in diameter with a pink, congested colour. Some laryngeal adenomata have been described as grey (Howarth and Chamings 1934). Rarely adenomata in this region are much larger, Figi et al (1944) reporting in one patient two distinct tumours which were respectively 5-5 cm.…”

Oncocytoma of the larynx

“…However, the numerous mitochondria with abundant respiratory enzymes have been thought to indicate a highly active rather than a senescent cell type. It has further been suggested that oncocytes may originate from ciliated epithelium (Howarth and Chamings, 1934) having undergone an 'oncocytic transformation' (Sasaki and Holmes, 1976). Although, the presence of acini displaying focal oncocytic change, as in the presented case, would support an origin from glandular epithelium.…”

“…Oncocytomas most often occur in elderly patients with the majority of reported cases being over 60 years of age. Occasional cases have been noted under 50 years of age (Howarth andChamings, 1934, Mendonca andWard, 1973;Bell et al, 1978) and exceptionally such tumours have been seen in very young patients (Figi et al, 1944). The prevalence in elderly patients is explained by the increased number of oncocytes present with advancing age (Mollica and Rossi, 1952).…”

Cystadenoma of Larynx

“…LESS than twenty cases of adenoma of the larynx have been reported in English laryngological literature in the past thirty years and only two cases, Howarth and Chamings (1934) and Ranger and Thackray (1953), in the Journal since Irwin Moore's classic paper on Adenoma of the Larynx in 1920, when he reported on thirteen cases, though in some of those the true pathology was doubtful.…”
