Skvamozni karcinom (Squamous cell carcinoma) obično se pojavljuje kao crvena, ljuskava, zadebljana lezija na koži izloženoј suncu. Neki se manifestuju kao čvrsti, tvrdi noduli i kupole nalik keratoakantom. Može doći do ulceracija i krvarenja. Kada se skvamozni karcinom (squamous cell carcinoma) ne liječi, može se razviti u veliku masu. Skvamozne ćelije su drugi najčešći tip raka kože. Opasan je, ali nije ni približno opasan kao melanom. Nakon biopsije, tumor će biti hirurški uklonjen.
Squamous cell carcinomas (SCCs), also known as epidermoid carcinomas, comprise a number of different types of cancer that result from squamous cells.

Squamous cell carcinoma well differentiated (dobro diferencirani skvamozni karcinom) – uočen je susedna aktinična keratoza.
Squamous cell carcinoma (SCC) je drugi najčešći rak kože u Sjedinjenim Državama, nakon basal cell carcinoma. Obično počinje od prekanceroznih lezija zvanih actinic keratosis, a može se proširiti i na druge dijelove tijela. Glavni uzrok je izlaganje ultraljubičastom (UV) zračenju sunca, koje se akumulira tokom vremena. Liječenje obično uključuje kirurško uklanjanje, posebno kod SCC‑a na glavi i vratu. Radioterapija je opcija za starije pacijente ili one koji ne mogu podvrgnuti operaciji. Imunosupresija povećava rizik od SCC. Iako je rijetko, SCC se može metastazirati, posebno kod pacijenata s oslabljenim imunološkim sistemom. Redovni pregledi i zaštita od sunca važni su za osobe s SCC‑om. Squamous cell carcinoma of the skin or cutaneous squamous cell carcinoma is the second most common form of skin cancer in the United States, behind basal cell carcinoma. Squamous cell carcinoma has precursor lesions called actinic keratosis, exhibits tumor progression and has the potential to metastasize in the body. Ultraviolet (UV) solar radiation is the primary risk factor in the development of cutaneous squamous cell carcinoma and the cumulative exposure received over a lifetime plays a major part in the development of this cancer. Surgical excision is the primary treatment modality for cutaneous squamous cell carcinoma, with Mohs micrographic surgery being the preferred excisional technique for squamous cell carcinoma of the head and neck, and in other areas of high risk or squamous cell carcinoma with high-risk characteristics. Radiation therapy is reserved for squamous cell carcinoma in older patients or those who will not tolerate surgery, or when it has not been possible to obtain clear margins surgically. Adjuvant radiotherapy is commonly after surgical treatment in very high tumors. Immunosuppression significantly increases the risk of squamous cell carcinoma over the course of an individual’s life. Metastasis is uncommon for squamous cell carcinomas arising in areas of chronic sun exposure, but it can take place, and the risk is increased in immunosuppressed patients. Patients with cutaneous squamous cell carcinoma should be examined regularly and remember to use measures to protect from UV damage.
Cutaneous squamous cell carcinoma (CSCC) je drugi najčešći rak kod ljudi, a njegova učestalost raste. Iako CSCC obično pokazuje benigno kliničko ponašanje, može se proširiti lokalno i na druge dijelove tijela. Naučnici su identificirali specifične puteve uključene u razvoj CSCC‑a, što je dovelo do novih tretmana. Veliki broj mutacija i povećani rizik kod imunosupresivnih pacijenata potakli su razvoj imunoterapije. Ovaj pregled razmatra genetske korijene CSCC‑a i najnovije tretmane usmjerene na specifične molekule i imunološki sistem. Cutaneous squamous cell carcinoma (CSCC) is the second most frequent cancer in humans and its incidence continues to rise. Although CSCC usually display a benign clinical behavior, it can be both locally invasive and metastatic. The signaling pathways involved in CSCC development have given rise to targetable molecules in recent decades. In addition, the high mutational burden and increased risk of CSCC in patients under immunosuppression were part of the rationale for developing the immunotherapy for CSCC that has changed the therapeutic landscape. This review focuses on the molecular basis of CSCC and the current biology-based approaches of targeted therapies and immune checkpoint inhibitors
