Abstract
A 32-year-old male with a history of albinism and farmer by occupation presented with an ulcerated plaque on the right wrist. The patient had
light eyes, hair, and skin. Physical examination showed extensive photodamage. A skin biopsy specimen from the plaque revealed a well-
differentiated squamous-cell carcinoma. Wide surgical excision was done. The most common types of oculocutaneous albinism (OCA), OCA
1 and OCA 2, are autosomal recessive disorders of pigmentation that commonly affect the skin, hair and eyes. Photodamage and skin cancers
plague patients with albinism. Albinos face a myriad of social and medical issues. Importance of photoprotection, skin cancer surveillance
and treatment has been stressed upon in this report.
Key words: albinism; photoprotection; melanin; squamous cell carcinoma
Introduction
Albinism is a genetically inherited disorder characterized
by hypopigmentation of the skin, hair and eyes due to a
reduced or lack of cutaneous melanin pigment production
[1]. Generally, there are two principal types of albinism,
oculocutaneous, affecting the eyes, skin and hair, and ocular
affecting the eyes only [1,2]. The mode of inheritance of
albinism is thought to vary, depending on the type. The
oculocutaneous type is considered autosomal recessive, and
the ocular variant sex-linked [1-3]. Ocular problems faced
by albinos are nystagmus, strabismus, photophobia, foveal
hypoplasia and decreased visual acuity. The cutaneous
problems seen with oculocutaneous albinism include
sunburns, blisters, centro-facial lentiginosis, ephelides, solar
elastosis, solar keratosis, basal cell carcinomas and squamous
cell carcinomas. Squamous cell carcinoma has been reported
to be the commonest skin malignancy seen in albinos [4,5].
Albinos are at an increased risk of developing skin malignancies
due to the absence of melanin, which is a photo protective
pigment, protecting the skin from the harmful effects of
ultraviolet radiation [6]. Hence, a regular examination for early
detection and treatment of these malignancies would increase
their life expectancy to a great extent. We report here a case of
oculocutaneous albinism with well-differentiated squamous
cell carcinoma in a farmer and also review oculocutaneous
albinism with emphasis on treatment and preventive aspects.
Case Report
A 32- year- old male, who was a known case of
Oculocutaneous Albinism, presented with an ulcerated lesion
over the right forearm. It started as a small wound which
arised from normal looking skin and gradually increased
to the present form over a period of six months. The patient
was a farmer who had occupational sun exposure with no
apparent photoprotection for the past ifteen years. History
of photosensitivity and photophobia was present. He was
born out of a non-consanguineous marriage. He had an elder
sibling who was unaffected, but had an affected irst-degree
relative.
On physical examination, generalized depigmented skin
with white hairs, brownish freckles and telangiectasia were
seen on his body (Fig. 1 - 3). Ocular Examination revealed
photophobia, nystagmus and decreased visual acquity.
Ulcerated plaque measuring 4cm x 3 cm with crusting with
rolled out edges was seen on the right wrist (Fig. 4a, b). It was
ixed to the underlying tissues. Regional lymphadenopathy
was absent. General physical and systemic examination was
normal.
