Although some observers have noted that the density of blood and lymphatic vessels in the superficial and deep lamina propria of BE is similar to that of non-Barrett esophagus, further studies are needed to evaluate the risk of lymphatic/vascular spread in patients with different depths of lamina propria invasion.

It consists of two laminae--a superficial lamina derived from the ipsilateral latissimus dorsi and a deep lamina from the contralateral muscle (Bogduk and Macintosh 1984).
The mild nuclear atypia, presence of signet ring-like tubules, infiltrating pattern into the deep lamina propria, including focal involvement of muscularis mucosae and superficial muscularis propria, were unusual and prompted an immunohistochemical workup to rule out malignancy.
Nephrogenic adenomas involving the deep lamina propria and/or superficial muscle can cause diagnostic difficulty and mimic malignancy, specifically prostatic adenocarcinoma, urothelial carcinoma with bland histology, and/or clear cell adenocarcinoma (Table).
Nephrogenic adenoma with focal solid and/or tubular pattern, especially with irregular borders and involving deep lamina propria/superficial muscularis propria, (10) may mimic certain urothelial carcinomas with deceptively bland features, such as the nested variant of urothelial carcinoma, urothelial carcinoma with small tubules, and microcystic urothelial carcinoma.
