Written by Medicover Team and Medically Reviewed by Dr Girishma J , Dermatologists
Table of Contents
Acroosteolysis-keloid-like lesions-premature aging syndrome, also known as Penttinen syndrome, is a rare genetic disorder that affects the bones, skin, and connective tissues. It is characterized by progressive loss of bone at the ends of the fingers and toes (acroosteolysis), keloid-like skin lesions, and features of premature aging. Other findings may include thin or atrophic skin, sparse hair, short stature, joint contractures, and skeletal abnormalities.
The condition is associated with pathogenic variants in the PDGFRB gene and follows an autosomal dominant inheritance pattern. Symptoms may begin in infancy or early childhood and vary among affected individuals. Early diagnosis and multidisciplinary care can help manage skeletal, skin, dental, and other complications.
What Are the Types of Acroosteolysis-Keloid-Like Lesions-Premature Aging Syndrome?
Acroosteolysis-keloid-like lesions-premature aging syndrome is a specific rare genetic disorder, rather than a condition divided into established clinical types. Its manifestations can vary among individuals.
- Skeletal manifestations: Acroosteolysis, brachydactyly, osteopenia, delayed bone maturation, and progressive joint contractures may occur.
- Skin manifestations: Thin or atrophic skin, loss of subcutaneous fat, and keloid-like or hypertrophic lesions are characteristic features.
- Premature aging features: A prematurely aged appearance may include wrinkled skin, sparse hair, and other changes affecting connective tissues.
- Growth and developmental features: Short stature, delayed tooth eruption, and other developmental abnormalities may be present.
What Are the Symptoms of Acroosteolysis-Keloid-Like Lesions-Premature Aging Syndrome?
Acroosteolysis-keloid-like lesions-premature aging syndrome can cause characteristic changes in the skin, bones, joints, and overall physical development. Symptoms may vary in severity and can become more apparent as the condition progresses.
- Acroosteolysis: Progressive resorption of the bones at the ends of the fingers and toes, which may cause deformities and shortening of the digits.
- Keloid-like skin lesions: Raised, thickened lesions that resemble scars and may develop particularly over areas exposed to pressure or minor trauma.
- Premature aging features: Thin, wrinkled, or translucent skin, reduced skin elasticity, sparse hair, and loss of subcutaneous fat may occur.
- Joint abnormalities: Joint stiffness, contractures, pain, and restricted movement may develop, particularly in the fingers and toes.
- Skeletal abnormalities: Brachydactyly, osteopenia, delayed bone maturation, and other skeletal changes may occur.
- Growth abnormalities: Some affected individuals may have short stature or delayed physical development.
- Dental abnormalities: Delayed tooth eruption and other dental problems may occur.
- Other features: Some individuals may develop distinctive facial features, thin hair, or muscle wasting.
What Are the Causes of Acroosteolysis-Keloid-Like Lesions-Premature Aging Syndrome?
Acroosteolysis-keloid-like lesions-premature aging syndrome is caused by pathogenic variants in the PDGFRB gene. This gene provides instructions for making platelet-derived growth factor receptor beta, a protein involved in cell signaling and the development and maintenance of connective tissues and other cells.
Changes in the PDGFRB gene can disrupt normal cellular signaling and contribute to the characteristic skeletal, skin, and connective tissue abnormalities associated with the syndrome.
Genetic Inheritance
The condition is usually inherited in an autosomal dominant pattern, meaning that a change in one copy of the PDGFRB gene can cause the disorder. Some reported cases result from a new genetic change that occurs in the affected individual and is not inherited from either parent.
When Should You See a Doctor for Acroosteolysis-Keloid-Like Lesions-Premature Aging Syndrome?
Consult a healthcare provider if a child or adult develops unusual skeletal changes, progressive joint stiffness, characteristic skin lesions, or features suggestive of premature aging.
- Progressive deformity or shortening of the fingers or toes
- Raised, keloid-like skin lesions that develop without a clear cause
- Thin, wrinkled, or unusually fragile skin or sparse hair
- Persistent joint stiffness, contractures, or difficulty moving the fingers and toes
- Short stature, delayed development, or delayed tooth eruption
- A family history of similar skeletal or skin abnormalities
Early specialist evaluation can help confirm the diagnosis, identify complications, and establish an individualized long-term care plan.

How Is Acroosteolysis-Keloid-Like Lesions-Premature Aging Syndrome Diagnosed?
Diagnosis involves evaluating the characteristic skeletal and skin findings, reviewing the individual's medical and family history, and performing appropriate genetic testing. Because the condition is extremely rare, evaluation by specialists familiar with genetic and skeletal disorders may be helpful.
Clinical Evaluation
- Physical examination: The doctor evaluates skin changes, keloid-like lesions, abnormalities of the fingers and toes, joint contractures, growth, and other characteristic features.
- Medical and family history: Information about the onset of symptoms and similar findings in relatives can help identify a possible inherited disorder.
- Dental and skeletal assessment: Delayed tooth eruption, bone abnormalities, and other structural changes may be evaluated.
Diagnostic Tests
- X-rays: Can demonstrate acroosteolysis, brachydactyly, delayed bone maturation, and other skeletal abnormalities.
- Genetic testing: Molecular testing can identify pathogenic variants in the PDGFRB gene and help confirm the diagnosis.
- Additional imaging: Other imaging studies may be used when needed to evaluate specific skeletal or joint abnormalities.
What Are the Treatment Options for Acroosteolysis-Keloid-Like Lesions-Premature Aging Syndrome?
There is currently no specific cure for acroosteolysis-keloid-like lesions-premature aging syndrome. Treatment focuses on managing symptoms, preserving mobility and function, addressing skin and skeletal complications, and supporting overall quality of life.
Management of Skeletal and Joint Problems
Orthopedic evaluation and physical therapy may help manage joint stiffness, contractures, pain, and movement limitations. Appropriate measures can help maintain mobility and function.
Skin Care
Dermatologic care may be recommended for keloid-like lesions, skin atrophy, and other skin complications. Treatment is individualized according to the location, size, and symptoms associated with the lesions.
Dental Care
Regular dental examinations are important because delayed tooth eruption and other dental abnormalities may occur. Preventive and restorative dental care can help maintain oral health.
Supportive Care
Regular monitoring of growth, bone health, joint function, skin changes, and other complications can help identify problems early. A multidisciplinary team may include geneticists, dermatologists, orthopedic specialists, dentists, physiotherapists, and other healthcare professionals depending on the individual's needs.
Genetic Counseling
Genetic counseling can help affected individuals and families understand the inheritance pattern, genetic testing results, and potential implications for family members and future pregnancies.

What Are the Risk Factors for Acroosteolysis-Keloid-Like Lesions-Premature Aging Syndrome?
Because this is a rare genetic disorder, the primary risk factor is carrying a disease-causing variant in the PDGFRB gene. The condition is usually inherited in an autosomal dominant manner, although some cases result from a new genetic variant.
- Family history: Having an affected parent can increase the likelihood of inheriting the condition.
- Genetic predisposition: A pathogenic PDGFRB variant is the principal known underlying risk factor.
- New genetic variants: The condition can occur in individuals without a previous family history because of a newly occurring genetic change.
