Histologically, the cystic lesion showed a benign pseudostratified
ciliated epithelium consistent with a foregut duplication cyst of the stomach.
Few areas had shown pseudostratified
lining epithelium with nuclear hyperchromasia, nuclear enlargement, and increased mitosis.
The respiratory epithelium consisted of pseudostratified
ciliated columnar epithelium with goblet cells (Figs.
The histology revealed muscle bundles and cystically dilated endometrial glands lined by pseudostratified
columnar epithelium with extensive area of haemorrhage Figure 1 and 2.
2 Photomicrographs show a tumour composed of variably sized tubules (a: Hematoxylin and eosin stain [H&E] x100) and cystic spaces (b: H&E x100) that are separated by thin, hypocellular fibrovascular septae (c: H&E x200), with the lining epithelium showing tombstone appearance focally (d: H&E x200); the tubules are lined by atypical cuboidal to pseudostratified
ciliated columnar cells (arrow) with abundant eosinophilic cytoplasm (e: H&E x400), large round to ovoid nuclei with prominent nucleoli (f: H&E x400) and hobnail appearance (g: H&E x600); solid areas show smaller tubules lined by similar atypical cells in a sclerotic stroma (h: H&E x200; i: H&E x400).
Fallopian tube revealed ciliated pseudostratified
It is lined by single layer of pseudostratified
cuboidal or columnar epithelium resembling gastrointestinal or respiratory epithelium.
The histologic appearance is very subtle, showing strips of flattened, pseudostratified
, ciliated, columnar epithelium.
The epithelial lining of the vomeronasal organs is lined with pseudostratified
cells, including sensory neurons.
A simple and efficient method for objective discrimination between pseudostratified
, metaplastic, and dysplastic nasal epithelium.
The flagellated cells, the principal cell type of the larva, are arranged in a pseudostratified
layer around a large central cavity.
Owing to their relative mucin depletion and pseudostratified
nuclei, confusion with endometrial endometrioid adenocarcinoma (EEA) is not uncommon.
