Histopathological examination revealed many tubular formations lined with
cuboidal epithelium in hyalinized stroma (Figure-2).
Acini and ducts of the mammary gland were lined with large
cuboidal epithelium cells.
This was characterized by a pseudoinfiltrative appearance of tubular-glandular structures with a pseudocystic appearance, lined by a single layer of
cuboidal epithelium with a hobnail appearance and focal atypias due to a degenerative process (Fig.
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 bile ducts are usually found near the portal vein and they are lined by simple
cuboidal epithelium.
Proximal convoluted tubules were lined by simple
cuboidal epithelium with prominent brush border and distal convoluted tubules were lined by simple
cuboidal epithelium with relatively larger lumen.
The cyst wall is lined by a single layer of
cuboidal epithelium and fibrous tissue.
a, Primitive ducts lined by
cuboidal epithelium (arrow) and surrounded by a fibromuscular collar *.
The histological study showed the presence of focal ducts lined with
cuboidal epithelium without atypia, located in areas of urothelial denudation (Fig.
macrophages with vacuolated cytoplasm) with pigmented cytoplasmic granules, presumably containing hemosiderin, were abundant within papillary fronds, which were lined with ciliated low
cuboidal epithelium (figure 4).
Histological sections were obtained for analysis of nuclear alterations in the
cuboidal epithelium of choroid plexuses of lateral ventricles in the rat fetuses.
BCC with sweat duct differentiation typically seen in nodular BCC in 1% of cases in our experience is otherwise typical eccrine, and sometimes, apocrine differentiation (3, 4) whereby tubules lined by the
cuboidal epithelium with an internal eosinophilic cuticle are centrally disposed in otherwise typical basaloid tumor cell aggregates.
