Insights
Phenylketonuria (PKU) can be associated with skin conditions like lichen sclerosus et atrophicus. This case study tracks the long-term progression of these dermatological changes in a middle-aged man with PKU.
Area of Science:
- Dermatology and Metabolic Disorders
Background:
- Phenylketonuria (PKU) is a rare genetic disorder affecting amino acid metabolism.
- Sclerodermatous changes have been previously noted in pediatric PKU cases.
Observation:
- A male patient diagnosed with PKU at 16 years old presented with lichen sclerosus et atrophicus.
- He later reappeared at the institution 35 years after initial diagnosis with extensive atrophic skin lesions.
Findings:
- This case provides a unique longitudinal perspective on the evolution of skin manifestations in adult PKU.
- The patient exhibited large, confluent areas of skin atrophy, indicating disease progression over decades.
Implications:
- Highlights the potential for chronic dermatological complications in adults with phenylketonuria.
- Suggests the need for long-term monitoring of skin health in individuals with PKU.
- Contributes to understanding the phenotypic spectrum of PKU beyond metabolic derangements.
Abstract:
A man with phenylketonuria who was reported to have lichen sclerosus et atrophicus at age 16 years presented to our institution 35 years later with large confluent areas of atrophy. Although sclerodermatous changes have been described in children with phenylketonuria, this case offers a longitudinal view of the progression of skin lesions in a middle-aged man with phenylketonuria.

01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
01:21Overview of Protein Metabolism
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

01:19Pigmentation
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...

01:19Type I Diabetes III: Clinical Manifestations
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
01:47Pleiotropy
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,...
01:25Jaundice
Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...
