Introduction:
Xeroderma pigmentosum (XP) significantly increases the risk of skin malignancies due to impaired DNA repair mechanisms. The estimated incidence is 1 in 250 000 in the USA. Patients with XP are more likely to develop cutaneous neoplasms, primarily melanoma, squamous cell carcinoma (SCC), and basal cell carcinoma (BCC), and the most prevalent cutaneous and ocular tumor is SCC.
Case Presentation:
We present a case of a 21-year-old male from western Nepal who presented to Tribhuvan University Teaching Hospital with multiple lesions on the face and was diagnosed with SCC and BCC. We comprehensively evaluated the chronology of events and associated pathology, and a detailed review of prior medical and surgical records was performed.
Discussion:
XP is an uncommon, autosomal recessive disorder with mutations in nucleotide excision repair genes. Patients with XP are more likely to develop cutaneous and ocular neoplasms early in life, which are more aggressive and have a high recurrence rate.
Conclusion:
Patients with XP can prolong their lives and avoid developing skin cancer by receiving early diagnosis and broad sun protection.

01:38Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
