Lipoma is an unusual benign tumor of the alimentary
tract that has an overall incidence rate of 4.1%.
However, esophageal localization is exceptionally
rare, with an incidence rate of only 0.4%.[
1] In their
study, Akiyama et al.[
2] reported the presence of 10
esophageal lipomas, with seven being in the cervical
esophagus and three in the thoracic esophagus.
Most esophageal lipomas are small and do not
require any intervention. Although pathologically
benign, a large esophageal lipoma can cause various
symptoms, including asphyxia secondary to airway
compression[
3] as well as central ulceration with
bleeding and pain. The management of esophageal
lipomas depends on the size and location of the
lesion.[
4] Currently, surgical excision by enucleation
is the favored treatment of esophageal lipoma.
Herein, we present the case of a 51-year-old man
with dysphagia. He underwent esophagography and
chest computed tomography (CT) at our facility, and
these revealed an 8x15 cm esophageal intraluminal
tumor mass (Figure 1). The mass was totally resected
via a right thoracotomy, and the pathology results
identified a lipoma (Figure 2). The procedure was successful, and he had an uneventful recovery
period.
Figure 1: (a) A barium swallow showed an 8x15 cm smooth
tumor in the upper part of the esophagus. (b) Chest computed
tomography revealed an 8x15 cm submucosal tumor (arrow) with
narrowing in the upper third of the thoracic esophagus.
Figure 2: (a) Magnetic resonance
imaging of the thorax showed a
submucosal elongated lipoma (arrow)
with luminal narrowing in the upper
third of the thoracic esophagus.
(b) An upper gastrointestinal
endoscopy showed a large mass
covered by a normal mucosa
arising from the posterior wall
(arrow= lipoma of the esophagus).
(c) Macroscopic findings of the
esophageal tumor revealed that it
was yellowish in color and had an
adipose tissue-like appearance.
