Digital clubbing, hyperhidrosis, acro-osteolysis and osteoporosis. A case resembling pachydermoperiostosis
Insights
This report details a Cambodian girl with pachydermoperiostosis, characterized by digital clubbing, hyperhidrosis, and bone abnormalities. The findings suggest a potential new mutation or autosomal recessive inheritance of this rare syndrome.
Area of Science:
- Genetics and rare diseases
- Skeletal dysplasias
- Dermatology
Background:
- Pachydermoperiostosis is a rare genetic disorder.
- It is characterized by skin thickening, digital clubbing, and bone changes.
- Genetic inheritance patterns can be autosomal dominant or recessive, or arise from new mutations.
Observation:
- A Cambodian girl presented with digital clubbing, profuse hyperhidrosis, and joint/leg pain.
- Radiographic examination revealed extensive acro-osteolysis of distal phalanges and generalized osteoporosis.
- There was no family history of similar symptoms, but her parents were consanguineous.
Findings:
- The patient's clinical and radiographic features are consistent with pachydermoperiostosis.
- The unusual X-ray changes in this case warrant further investigation.
- The presentation suggests either a de novo mutation or autosomal recessive inheritance.
Implications:
- This case expands the clinical spectrum of pachydermoperiostosis.
- Understanding the genetic basis is crucial for diagnosis and genetic counseling.
- Further research may elucidate the specific genetic mechanisms in autosomal recessive forms.
Abstract:
We report a Cambodian girl with digital clubbing, profuse hyperhidrosis, and joint and leg pain and swelling. She also had extensive acro-osteolysis of distal phalanges as well as generalized osteoporosis. There was no other affected person in the family, but her parents were first cousins. Although the X-ray changes are unusual, this patient probably represents a case of pachydermoperiostosis, either occurring as a new mutation or inherited as an autosomal recessive syndrome.
