Benign Neoplasms Of The Esophagus
Category: ENDOSCOPY IN MALIGNANT DISEASE OF THE LARYNX
Source: A Manual Of Peroral Endoscopy And Laryngeal Surgery
As a result of prolonged inflammation edematous polypi and granulomata
are not infrequently seen, but true benign tumors of the esophagus are
rare affections. Keloidal changes in scar tissue may occur. Cases of
retention, epithelial and dermoid cysts have been observed; and there
are isolated reports of the finding of papillomata, fibromata,
lipomata, myomata and adenomata. The removal of these is readily
accomplished with the tissue forceps (Fig. 28), if the growths are
small and projecting into the esophageal lumen. The determination of
the advisability of the removal of keloidal scars would require
careful consideration of the particular case, and the same may be said
of very large growths of any kind. The extreme thinness of the
esophageal walls must be always in the mind of the esophagoscopist if
he would avoid disaster.
