Pachydermoperiostosis with myelofibrosis and empty sella

Area of Science:

• Rheumatology
• Genetics
• Internal Medicine

Background:

• Pachydermoperiostosis (PP) is a rare genetic disorder characterized by a triad of skin thickening, digital clubbing, and arthralgia.
• The exact prevalence and genetic underpinnings of PP are not fully elucidated, necessitating further case studies.

Observation:

• A patient presented with refractory knee joint pain and swelling, indicative of potential rheumatological conditions.
• Distinctive facial features, severe digital clubbing (grade four), and broadening of distal extremities were noted.
• Fatiguability secondary to anemia was a significant accompanying symptom, suggesting systemic involvement.

Findings:

• The clinical presentation strongly suggested pachydermoperiostosis, despite the absence of typical skin thickening in this particular case.
• The constellation of symptoms, including arthralgia, digital clubbing, and facial changes, aligns with known manifestations of PP.
• Anemia was identified as a contributing factor to the patient's fatigue, requiring further investigation into its etiology within the context of PP.

Implications:

• This case underscores the phenotypic variability of pachydermoperiostosis, emphasizing the need for a high index of suspicion in patients with suggestive features.
• Early recognition and comprehensive management are crucial for addressing the diverse clinical manifestations, including joint symptoms and anemia.
• Further research into the natural history and molecular basis of PP can improve diagnostic accuracy and therapeutic strategies.
