Resumen (ES)
Solitary epithelioid hemangioendothelioma of bone,
characterized by epithelioid or "histiocytoid" endothelial cells
has a difficult diagnosis, confusing or unknown prognosis and
unpredictable outcome. Unfrequently recognized in bone, its
etiology is not clear with a very variable clinical course.
Multicentricity and multifocality are two characteristics of this
tumuor, with a predilection for lower extremity bones. Therefore
solitary lesions may be difficult to diagnose being confused
with metastatic carcinomas and other entities. Its treatment is
not well established. Their aggressive potential is unpredictable,
to such a point that ablative surgery may be more frequent
than previous reports have shown. Its diagnosis and treatment
must be exhaustive as aggressive behaviour with insidious evolutions
ending as relapses have been described. The three
pillars on which we will base its treatment are: in-block resection,
complete coverage of the residual bone lesion and postoperative
radiotherapy.
