Summary
Pachydermodactyly, a finger fibromatosis, was observed in a man with psychiatric disease and mental retardation. This case also presented with acrocyanosis and plantar pachydermy, a novel association.
Area of Science:
- Dermatology
- Pathology
- Genetics
Background:
- Pachydermodactyly is a rare superficial fibromatosis affecting finger phalanges and joints.
- It presents with varying topography, etiology, and pathological associations.
- This report details a unique case of pachydermodactyly with associated plantar pachydermy.
Observation:
- A 19-year-old male with a history of psychotic disease and mental retardation presented with typical pachydermodactyly on bilateral fingers.
- The patient also exhibited recent acrocyanosis and pachydermic changes on the soles of his feet.
- Histopathological analysis revealed collagen swelling in both digital and plantar lesions.
Findings:
- The case aligns with classical pachydermodactyly, predominantly affecting men's fingers.
- Unusual findings included significant acrocyanosis, functional disability, and the novel association with plantar pachydermy.
- Histology showed identical collagen swelling in both digital and plantar lesions, extending into subcutaneous fat on the feet.
Implications:
- The findings suggest pachydermodactyly may be part of a broader spectrum of acral pachydermy.
- The co-occurrence with psychiatric disorders and history of trauma, though reported, warrants further investigation.
- This case expands the understanding of pachydermodactyly's clinical presentation and potential underlying mechanisms.
