“…Criteria for the identification of a leiomyoma derived from the MM of the esophagus are: 1) presence of hypoechoic mass of the second layer of the esophageal wall with well-defined boundaries, 2) homogenous internal echo pattern, and 3) normal overlying mucosa. EUS with high frequency ultrasonic probe is superior to other imaging modalities for detecting the origins of leiomyomas and estimating histologic characteristics of tumors,5,6 as a conventional EUS has difficulty capturing the precise images of small leiomyomas in the esophagus because of difficulty in direct visualization of the tumors and its poor imaging resolution with low frequency ultrasound. High frequency ultrasonic endoprobe can provide direct endoscopic visualization of a small tumor during ultrasonic scanning and it is easier to access a small mural esophageal lesion.…”

Esophageal leiomyoma derived from the muscularis mucosae (MM) is a rare condition, and the optimal modality for diagnosis and treatment is controversial. Endoscopic ultrasonography can provide an accurate image of esophageal layer structure, providing information on lesion suitability for potential endoscopic therapy. We attempted to investigate the diagnostic value of a transendoscopic balloon-tipped miniature ultrasonic endoprobe for small esophageal leiomyomas derived from MM. We resected 7 small esophageal leiomyomas derived from MM by endoscopic mucosal resection (EMR), all of which were diagnosed by a balloon-tipped endoprobe. The endosonographic and pathologic features of 7 cases of small esophageal leiomyomas derived from MM were compared. The balloon-tipped endoprobe clearly showed all 7 small esophageal leiomyomas derived from MM, even those under 5 mm in size (smallest lesion, 3.0 mm). The endosonographic characteristics of small esophageal leiomyomas derived from MM were a hypoechoic mass with smooth, regular, and a well-defined outer margin and homogenous inner echogram arising from the second hypoechoic layer. Complete resections were possible in all 7 cases by EMR without any complications. Tumor size was 3.0 - 13.5 mm (mean 7.8 mm) in maximum diameter. In all cases, endosonographic findings by endoprobe were exactly concordant with pathologic finding in determining the tumors depth in the esophageal wall, tissue origin and characteristics, growth pattern, and size. We detail the balloon-tipped endoprobe is a simple, convenient, and very useful in making accurate diagnosis of small esophageal leiomyomas derived from the MM and the appropriate applications of EMR.

“…Endoscopy and biopsy specimens of metastatic esophageal tumors usually show normal or inflamed mucosa and are reported to be positive for tumor in only 50% of cases [9,15,17,22,[41][42][43]. Because of the increased incidence of esophageal perforation, some authors do not advocate these procedures for patients with a history of breast carcinoma who present with esophageal symptoms and show radiographic evidence of esophageal involvement [43].…”

A review of 62 cases of esophageal involvement by secondary neoplasms is reported. The common routes of esophageal involvement are by direct extension of the tumor from the contiguous or adjacent organs (45.2%), via mediastinal nodes (35.5%), and hematogenous spread from a distant primary (19.3%). In the first 2 modes of esophageal involvement, the diagnosis is usually obvious but hematogenous metastases to the esophagus usually pose a diagnostic challenge. Radiologically, hematogenous metastases show a spectrum of features consisting of a short segment of progressive stricture with normal to minimally irregular mucosa, a submucosal mass with or without ulceration, a polypoid mass or masses, and defects in esophageal motility including secondary achalasia. Since endoscopy and biopsy have limited diagnostic yield, radiologic diagnosis plays a key role in the diagnosis of secondary neoplasms of the esophagus irrespective of their mode of spread to the esophagus.

“…Leiomyosarcoma may also appear in the form of submucosal or infiltrating lesion, the latter being much more frequent. Endoscopy is useful in the diagnosis of esophageal leiomyosarcoma, but it may not be obviously specific [11].…”
