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.
This present work aimed to survey the diversity of the species of ciliated
protists in a neotropical lotic urban system located in Southern region of Minas Gerais state, Brazil.
protozoa of the genus Trichodina are one of the most common ectoparasites of both freshwater and marine fishes.
Simple tall cuboidal to columnar epithelial "epidermal" cells, which may be pigmented, interspersed with mucus cells and ciliated
cells, make up the epidermis (Fig.
It is of a great importance to distinguish the protozoon from ciliated
respiratory epithelium to avoid wrong positivity (7-9).
Male and female adults are produced from germinal cells within the plasmodia, and the ciliated
adults swim out from the hosts.
muconodular papillary tumor (CMPT) is a rare pulmonary tumor first described in 2002 by Ishikawa.
protozoa play important role in regulating the fermentation by utilizing the sugars and starch, which they sequesters from the bacteria.
The cystic lesions were then evaluated for histopathological variables which included presence or absence of keratinization, cytological atypia and tumour arising within cyst lining, foamy macrophages, mucous cells, vacuolated cells, Rushton bodies, spongiosis , ciliated
cells , necrosis, micro-abscesses and Russel bodies, cholesterol crystals, hemosiderin and inflammatory infiltrate.
In the histological examination, the cyst was lined by flattened, cuboidal or ciliated
columnar epithelium supported by underlying fibrous stroma (Figure 2b).
The noninflamed cyst shows 2 to 3 cell layers of cuboidal to squamoid cells adjacent to fibrous connective tissue (figure 2), rarely showing ciliated
, mucous, or sebaceous cells.
In particular, bitter receptors expressed on ciliated
cells have been found to be stimulated by bacterial compounds and cause downstream release of nitric oxide (NO), as shown in Figure 1 [38,39].
