Summary
Xeroderma pigmentosum (XP) is rare in African-Americans. This case details a middle-aged woman with XP who developed multiple skin cancers, highlighting the need for vigilant monitoring and early intervention in diverse populations.
Area of Science:
- Dermatology
- Genetics
- Oncology
Background:
- Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder characterized by defective DNA repair, leading to extreme photosensitivity and a high risk of cutaneous malignancies.
- XP predominantly affects individuals of European descent, with limited documented cases in African-American populations.
Observation:
- A 34-year-old African-American woman presented with xeroderma pigmentosum.
- She developed her first cutaneous squamous cell carcinoma (SCC) at age 23, followed by additional SCCs, basal cell carcinomas, and melanoma in situ.
- Management involved strict sun avoidance, photoprotection, and multiple surgical excisions.
Findings:
- This case represents a rare presentation of XP in a middle-aged African-American woman.
- The patient experienced early-onset and diverse cutaneous neoplasms, including SCC, BCC, and melanoma.
- The clinical course was prolonged, underscoring the aggressive nature of XP-associated malignancies.
Implications:
- XP can manifest in diverse demographics, challenging typical presentation expectations.
- Frequent dermatological surveillance and a low threshold for intervention are crucial for managing XP patients.
- This case emphasizes the importance of considering XP in individuals of African descent presenting with multiple or early-onset skin cancers.

Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
X-linked Traits
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.
Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Epistasis
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
