What is non Keratinizing carcinoma?

Nonkeratinizing carcinoma (NKCa) is a rare malignancy of the nose and paranasal sinuses. The incidence of sinonasal malignancy is approximately 3.5/100,000 population per year. Of this, 15%–20% are NKCa.

What does Keratinizing mean in cancer?

Squamous cell carcinoma (SCC) is a health condition involving the uncontrolled growth of the outer squamous cells of the epidermis, which is the outermost layer of the skin. SCC occurs as a result of keratinization of the epidermal cells and has the potential to metastasize to other regions of the body.

What is non Keratinizing type?

According to the World Health Organization (WHO), NPC is classified into 3 subtypes: Keratinizing squamous cell carcinoma (WHO type 1) Nonkeratinizing squamous cell carcinoma (WHO type 2) Undifferentiated or poorly differentiated carcinoma, including lymphoepithelioma and anaplastic variants (WHO type 3)

What causes non Keratinizing squamous cell carcinoma?

Human papilloma virus (HPV) is an etiologic agent in a subset of oropharyngeal squamous cell carcinomas (SCCs).

Is a squamous cell carcinoma benign or malignant?

The vast majority of skin cancers are basal cell carcinomas and squamous cell carcinomas. While malignant, these are unlikely to spread to other parts of the body if treated early. They may be locally disfiguring if not treated early.

What is Keratinised skin?

Skin, hair and nails are keratinised, meaning they have a dead and hardened impermeable surface made of a protein called keratin. Mucous membranes are non-keratinised and moist.

What is Basaloid squamous cell carcinoma?

Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive variant of oral squamous cell carcinoma with a predilection for the tongue and in other locations, such as floor of the mouth, palate, retromolar trigone, and gingival mucosa.

What is non Keratinizing squamous cell carcinoma cervix?

Definition. A squamous cell carcinoma composed of large atypical cells, without morphologic evidence of keratin production. [ from NCI]

Can squamous cell carcinoma be cured?

Most squamous cell skin cancers are found and treated at an early stage, when they can be removed or destroyed with local treatment methods. Small squamous cell cancers can usually be cured with these treatments.

What happens to untreated squamous cell carcinoma?

Untreated squamous cell carcinoma of the skin can destroy nearby healthy tissue, spread to the lymph nodes or other organs, and may be fatal, although this is uncommon. The risk of aggressive squamous cell carcinoma of the skin may be increased in cases where the cancer: Is particularly large or deep.
