Familial angiolipomatosis

S A Hapnes, H Boman, S O Skeie

    Clinical Genetics
    |January 1, 1980
    PubMed
    Summary

    Large angiolipomata, benign fatty tumors, were found in an adolescent boy, recurring after surgery and causing bone deformities. Similar tumors in his sister suggest a possible genetic cause for these rare growths.

    Area of Science:

    • Medical research
    • Genetics
    • Orthopedics

    Background:

    • Angiolipomata are benign tumors composed of blood vessels and fat.
    • Subcutaneous angiolipomata are rare, particularly when large and bilateral.

    Observation:

    • An adolescent male presented with large, bilateral subcutaneous angiolipomata around major joints (wrists, knees, ankles).
    • Tumors exhibited slow growth since early childhood and extended deeply without infiltrating surrounding structures.
    • Associated findings included muscular hypotrophy and bone deformities near affected joints.

    Findings:

    • Recurrence of angiolipomata after subtotal excision indicates aggressive local behavior.
    • The presence of similar tumors in a sibling strongly suggests a hereditary component.

    Implications:

    • This case highlights the potential for significant morbidity associated with large angiolipomata, including functional impairment and skeletal changes.
    • Further investigation into the genetic basis of familial angiolipomata is warranted to understand pathogenesis and guide treatment.
