Xeroderma pigmentosum (XP) is a rare autosomal recessive disease caused by a gene defect, leading to deficient deoxyribonucleic acid repair. The sun-exposed areas of the body predominantly skin, eyelid, and ocular surface are greatly affected by ultraviolet radiation. In this case series, we report eight children with XP seen over a period of 5 years. All these cases had complaints of photophobia and early lentiginosis in sun-exposed area. Clinical presentation varied from lid freckles, conjunctival hyperemia, conjunctival melanosis, corneal opacity with vascularization, actinic keratosis to skin malignancy. One child with squamous cell carcinoma of the neck died at the age of 5 years. This case series describes the oculocutaneous manifestations seen in Indian children with XP. It also highlights the significance of regular multidisciplinary health check-up to prevent life-threatening complications in these patients.

| Introduction|| |
Xeroderma pigmentosum (XP) is a rare autosomal recessive disease characterized by heightened sensitivity to the deoxyribonucleic acid (DNA) damaging effects of ultraviolet (UV) radiation.,, It has a 10,000-fold increased risk for skin cancer and a 2000-fold increased risk for cancer of eye and ocular adnexa., Patients usually present with freckle-like pigmentation in sun-exposed skin before 2 years of age, severe photosensitivity after minimal sun exposure, and damage to ocular surface with permanent loss of vision. About 25% of patients may develop a progressive neurodegeneration. There is no definitive treatment for XP, but many of its complications may be reduced by consistent UV protection, thus helping these patients to live active lives.
| Case Report|| |
This case series included eight children with XP of age ranging from 8 months to 12 years, comprising five boys and three girls. There was a history of consanguinity in parents of three children. Out of them, two were siblings and the older child died subsequently at the age of 5 years due to cutaneous malignancy. Four children had stunted growth. All cases had complaints of photophobia and early lentiginosis in sun-exposed area. The age of onset of disease manifestations was within 2 years of life in majority of cases (five out of eight); one had as early as 20 days. The clinicodemographic details [Figure 1], [Figure 2], [Figure 3], [Figure 4] of all children with XP are shown in [Table 1].,,,

Dry eye evaluation could be performed in three cases. Tear film break-up time was found to be grossly reduced in these cases.
| Discussion|| |
Moritz Kaposi, a Hungarian dermatologist, first described XP as a severe form of photosensitivity disorder associated with pigmentation of skin in sun-exposed area.
UV radiation, particularly spectrum B, causes photo products in DNA, which leads to cell death, mutagenesis, carcinogenesis, and cellular aging. XP is an autosomal recessive disorder resulting from mutations in any of the eight genes responsible for restoration of UV radiation-induced DNA damage. This results in accelerated skin aging and cellular transformation causing malignancies in young age.
Symptoms may differ from person to person, but it typically affects the skin, eyes, and nervous system. These patients develop lentiginosis on all sun-exposed area, often seen first on face. In this case series, all children had early skin freckles mostly on scalp, face, neck, and extremities. Basal cell carcinoma, squamous cell carcinoma (SCC), and malignant melanoma are common neoplasms seen in XP. Out of eight cases, we noted SCC in three children. One child had multiple SCC on the scalp at the age of 4 years. All growths were excised and confirmed to be SCC on histopathology [Figure 5]. Two months later, the child presented again with few more similar lesions on the scalp. Due to anatomical peculiarity and rich vascularity, SCC in the scalp tends to have an aggressive course. Hence, any such lesions should be excised as early as possible. The other two children had solitary lesions; one had on neck and the other had on lip. The child with SCC on the neck died at the age of 5 years. Avoidance of UV exposure right from birth and medical check-up at regular intervals can prevent such life-threatening malignancies in children with XP.

The eyelids and ocular surface are usually affected within the first decade of life. Photophobia is common and is often noted in early childhood. Patients with XP also develop sunlight-induced conjunctival inflammation, dry eye, keratitis, and corneal opacification with vascularization. These combined effects may contribute to permanent loss of vision. With repeated sun exposure, the lids of the eyes may undergo atrophic degeneration. Cancers of the eyelids and ocular surface have been reported.,, Among various ocular features, we noted photophobia, excessive lacrimation, lid freckles, blepharitis, conjunctival injection, corneal opacity, punctate keratitis, and dry eye. We did not find any case of ocular malignancy.
XP is frequent after consanguineous marriage. In this case series, consanguinity was found in parents of about one-third of children. All these cases were from southern districts of Odisha, where consanguinity is a common practice. In this case series, consanguinity was found in parents of about one-third of children. All these cases were from southern districts of Odisha.
| Conclusion|| |
Children with XP, who presented to a tertiary eye care center in Eastern India, had a high percentage of consanguinity in parents and early onset of oculocutaneous complications including skin malignancies. Dry eye disorder is also common among these patients. Although XP is a rare disease, risk of death in childhood due to complications is very high. XP is not curable; however, most of its complications can be reduced by preventing consistent UV exposure. Educating the parents to provide adequate sun protection and appropriate medical care from childhood will definitely increase life expectancy in these children.
