Abstract:
Xeroderma pigmentosa (XP) is a rare autosomal
recessive disorder which is characterized by a defect in
nucleotide excision repair of DNA following exposure to
UV radiation. This leads to hypersensitivity to sunlight
causing pigmented skin lesions, photophobia and a
1000-fold increase in risk of developing cutaneous malignancies
like basal cell carcinomas, squamous cell carcinomas
and melanomas of head and neck. We present an
interesting case of a 28 year old man with basosquamous
cell carcinoma secondary to XP treated successfully with
surgical excision and reconstruction with rotational flap
technique.
