Overview
Although the exact causes were unknown, the following are some of the factors that have been associated with the development of basal cell carcinoma: radiation exposure, gene mutations, xeroderma pigmentosa, epidermodysplastic verruciformis, nevoid basal cell carcinoma syndrome, bazex syndrome, rombo syndrome etc.
Basal Cell Carcinoma Causes
Although the exact cause is unknown, there are some environmental and genetic factors that may predispose to basal cell carcinoma.
The following table summarizes the causes of basal cell carcinoma (BCC):
| Cause | Description |
| Radiation exposure | Sunlight (UV light), tanning beds, and x-rays exposure are associated with basal cell carcinoma formation[1] |
| Gene mutations | TP53 gene mutations and the inappropriate activation of the hedgehog signaling pathway (loss-of-function mutations in tumor-suppressor protein patched homologue 1 (PTCH1) and gain-of-function mutations in sonic hedgehog (SHH), smoothened (SMO) are associated with basal cell carcinoma[2] |
| Xeroderma pigmentosum | This an autosomal recessive disorder; it results in the inability to repair ultraviolet-induced DNA damage; pigmentary changes are seen early in life, followed by the development of basal cell carcinoma, squamous cell carcinoma, and malignant melanoma; other features include corneal opacities, eventual blindness, and neurological deficits[3] |
| Epidermodysplastic verruciformis | Epidermodysplastic verruciformis is an autosomal recessive disorder characterized by the development of basal cell carcinoma and squamous cell carcinoma from warts (human papillomavirus infection)[4] |
| Nevoid basal cell carcinoma syndrome | This is an autosomal dominant disorder that can result in basal cell carcinomas, multiple odontogenic keratocysts, palmoplantar pitting, intracranial calcification, and rib anomalies[5] |
| Bazex Syndrome | The features of bazex syndrome include follicular atrophoderma, multiple basal cell carcinomas, and local anhidrosis[6] |
| Rombo syndrome | Rombo syndrome is an autosomal dominant condition distinguished by basal cell carcinoma and atrophoderma vermiculatum, trichoepitheliomas, hypotrichosis milia, and peripheral vasodilation with cyanosis[7] |
