Stratified mucin-producing intraepithelial lesions of the cervix: adenosquamous or columnar cell
(b) The suprabasal layer shows stellate reticulum-like formation, and the basal layer shows palisading tall columnar cell
nuclei with focally mitoses (arrowheads) (HE; original magnification: x40 (a) and x200 (b)).

and tall cell variant of papillary carcinoma of thyroid: a case report and review of the literature," Pathology, vol.
The breast ducts showed columnar cell
change with apical snouts.
(8) Similarly, columnar cell
change in ducts also exhibits loss of high-molecular-weight cytokeratins, as well as diffuse expression of estrogen receptor in the absence of atypia.
Theoretically, the increase reflects a greater circumferential and more representative columnar cell
sample obtained from the endocervical canal.
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).
Lesions labeled as columnar cell
lesions included columnar cell
change and/or columnar cell
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).
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.
Final pathology identified the mass as a columnar cell
variant of papillary thyroid carcinoma (PTC).
