Microscopically, multilocular cystic nephroma demonstrates multilocular cysts lined by a single layer of flattened, low, cuboidal epithelium
with eosinophilic cytoplasm and no nuclear atypia.
2) They felt the histologic appearance of the tumors was most consistent with an origin from columnar or cuboidal epithelium
, with limited nonmucous secretoryactivity.
The histological study showed the presence of focal ducts lined with cuboidal epithelium
without atypia, located in areas of urothelial denudation (Fig.
Surrounding the main pancreatic duct along its length and under the cuboidal epithelium
was abundant ovarian-type stroma with focal clusters of luteinized cells (Figure 3).
macrophages with vacuolated cytoplasm) with pigmented cytoplasmic granules, presumably containing hemosiderin, were abundant within papillary fronds, which were lined with ciliated low cuboidal epithelium
3,22) Microscopically, it consists of relatively uniform ductules lined by bland cuboidal epithelium
and separated by fibrotic stroma, sometimes containing dense chronic inflammation.
Although their cause has not been clearly determined, they are known to be retention cysts that are lined with columnar or cuboidal epithelium
6,7) As shown, an aggressive digital papillary adenocarcinoma may exhibit cystic areas with true papillary formations of cuboidal epithelium
8%) (figure 2), and simple cuboidal epithelium
in two (11.
The characteristic histologic features of this tumor include multiple microcysts separated by fine connective tissue septa, lined by flattened or cuboidal epithelium
, and most often filled with proteinaceous fluid.
