The breast ducts showed columnar cell change with apical snouts.
Lesions labeled as columnar cell lesions included columnar cell change and/or columnar cell hyperplasia.
After 3-10 min of incubation, the precipitate appeared in the basal two-thirds of columnar cell cytoplasm (Fig.
Theoretically, the increase reflects a greater circumferential and more representative columnar cell sample obtained from the endocervical canal.
However, it is important to note that columnar cell alteration (columnar cell change/hyperplasia) and apocrine metaplasia, which are commonly seen in IDPs, are also negative for CK5/6 and thus may be a pitfall in stain interpretation.
In the present study, fibrocystic disease is the predominant benign lesion comprising 39 cases (41%), followed by fibroadenoma 26 cases (28%), fibrocystic disease with columnar cell change 13 cases (14%), sclerosing adenosis 8 cases (8%), intraductal papilloma 5 cases (5%), apocrine adenoma 3 cases (3%), benign phyllodes 1 case (1%) (Figure 2).
b and c, Papillary structures with stromal cores containing histiocytes and covered by concentric rings of columnar cell layers.
The percentage of mindbomb homolog-1-positive cells among the stromal cells was 60%, whereas epithelial membrane antigen, AE1/AE3, and prostatic acid phosphatase were positive in the columnar cell lining the epithelial components, leading to a diagnosis of a high-grade malignant phyllodes tumour of the prostate.
The hallmark appearance of an oncocytic cell is one of a large cuboidal to columnar cell with hyperchromatic nuclei and finely granular eosinophilic cytoplasm (figure 2).
Rarely, the lining cells may take on a columnar cell appearance that contains subnuclear vacuoles and shows reverse polarity, thus simulating piano keys.
Tubular carcinoma can also be an incidental finding in a biopsy performed for calcifications that are present in an adjacent benign proliferation, such as columnar cell change.
Final pathology identified the mass as a columnar cell variant of papillary thyroid carcinoma (PTC).
