[Macrodystrophia lipomatosa. Angiographic aspects (author's transl)]

Area of Science:

• Medical case reporting
• Rare disease characterization
• Histopathology

Background:

• Macrodystrophia lipomatosa is a rare congenital condition characterized by localized overgrowth of adipose tissue.
• It typically affects one or two digits of the hand or foot.
• The exact etiology remains unclear, but a dysembryoplasic origin is suspected.

Observation:

• A 43-year-old male presented with hypertrophy of the first and second left fingers.
• Radiographic examination revealed bony overgrowth and significant soft tissue thickening.
• Arteriography excluded vascular anomalies such as angioma or arteriovenous fistula.

Findings:

• Histologic examination of the affected digits showed deposits of fat within the thickened soft tissues.
• The bony overgrowth and soft tissue hypertrophy are consistent with Macrodystrophia lipomatosa.
• The condition's presentation and findings differentiate it from other hamartomas.

Implications:

• This case contributes to the understanding of Macrodystrophia lipomatosa, a rare dysembryoplasic entity.
• Further investigation into the developmental origins of Macrodystrophia lipomatosa may clarify its relationship to other hamartomas.
• Accurate diagnosis relies on a combination of clinical, radiographic, and histologic findings.
