Introduction:

Acropachy is a rare manifestation characterized by clubbing of the fingers and toes, along with periosteal new bone formation in the distal phalanges. This article aims to provide insights into the symptoms, causes, diagnosis, and management of acropachy, aiding in better understanding and management of this condition.

Symptoms:

Acropachy typically presents with the following clinical features:

Digital Clubbing:

• Gradual enlargement and rounding of the fingertips and toes.
• Loss of the normal angle between the nail bed and the nail plate, known as Lovibond's angle.
• Increased soft tissue around the nail bed, leading to a bulbous appearance.

Periosteal New Bone Formation:

• Formation of new bone along the periosteum of the distal phalanges, visible on radiographic imaging.
• Thickening and sclerosis of the distal phalanges, contributing to the characteristic appearance of acropachy.

Causes:

Acropachy can be associated with various underlying conditions, including:

Pulmonary Disorders:

• Chronic respiratory diseases, such as bronchiectasis, lung cancer, or pulmonary fibrosis, may lead to secondary acropachy due to chronic hypoxia and tissue hypoxemia.

Cardiovascular Disorders:

• Congenital heart diseases, such as cyanotic heart disease, can result in chronic hypoxemia and subsequent development of acropachy.

Endocrine Disorders:

• Thyroid acropachy, a rare manifestation of Graves' disease, presents with digital clubbing, periosteal new bone formation, and dermopathy.

Malignancies:

• Neoplastic processes, particularly lung cancer or metastatic bone disease, may lead to paraneoplastic acropachy as a manifestation of chronic hypoxemia or tumor-produced factors.

Diagnosis:

Diagnosis of acropachy involves a combination of clinical evaluation and diagnostic imaging:

Clinical Assessment:

• Detailed history-taking, focusing on symptoms, duration, and associated medical conditions.
• Physical examination to assess for digital clubbing, periosteal new bone formation, and signs of underlying systemic diseases.

Radiographic Imaging:

• Plain radiographs, such as X-rays, of the hands and feet to visualize periosteal new bone formation and sclerosis of the distal phalanges.

Management:

Management of acropachy primarily involves addressing the underlying cause and alleviating symptoms:

Treatment of Underlying Conditions:

• Targeted management of associated systemic diseases, such as respiratory or cardiovascular disorders, to improve oxygenation and prevent disease progression.

Symptomatic Relief:

• Analgesics and anti-inflammatory medications may be prescribed to alleviate pain and discomfort associated with periosteal new bone formation.
• Topical treatments, such as emollients, may help manage skin changes and nail abnormalities.

Supportive Care:

• Patient education regarding the underlying condition, lifestyle modifications, and preventive measures.
• Regular follow-up with healthcare providers for monitoring of symptoms and disease progression.

Conclusion:

Acropachy is a rare manifestation characterized by digital clubbing and periosteal new bone formation in the distal phalanges. Understanding the symptoms, causes, diagnosis, and management of acropachy is essential for timely intervention and comprehensive care of affected individuals.
