Histopathologic examination of the cystic mass identified BCC with connective tissue and lymphoid aggregates on its wall, and with multiloculated lumen covered in ciliated and focal stratified squamous epithelium
in larger areas.
The histological observation revealed that in Group B the whole wound was covered with thin layer of stratified squamous epithelium
on day 7 with very little or without fibrinous exudate.
Condylomata usually arise after low-risk (LR) HPV infection of a well-developed stratified squamous epithelium
; thus, these lesions show thick epithelium with koilocytes in the superior cell layers.
Field cancerization in oral stratified squamous epithelium
: clinical implications of multicentric origin.
Dermoid cysts are layered by stratified squamous epithelium
and contain skin and skin adnexa (glands and hair follicles).
Histopathological studies confirmed the diagnosis that the mass was a dermoid cyst with a stratified squamous epithelium
lining, contents from products of adnexal structures and hair follicles [Figures 4 and 5].
Microscopic examination revealed that the cystic structures were lined by keratinizing stratified squamous epithelium
(skin) and ciliated bronchial epithelium (Figure 4b, c).
In the presence of adequate endogenous estrogen (principally estradiol), the vaginal wall is a thickly stratified squamous epithelium
with a rugated surface that is rather elastic.
The histopathological examination showed a cystic lumen with a thin stratified squamous epithelium
, and a dense fibrocellular connective tissue wall with chronic inflammatory infiltrate.
Regarding histopathology, the lesions in each patient were composed of stratified squamous epithelium
with parakeratosis covering bundles of striated muscles, without the normal skin appendages.
Histopathologic examination following excision revealed overlying parakeratinized stratified squamous epithelium
at either end with ulceration and discontinuity at the centre (Figures 7(a) and 7(b)).
An incisional biopsy was performed, and intraoperative frozen section revealed a "stratified squamous epithelium
, fat, and skeletal muscle lesion--in keeping with a teratoma." The tumor was gradually debulked and removed endoscopically with a microdebrider (Skimmer[R]) (Figure 2(b)).
