Resección en bloque de un tumor de células gigantes del cúbito distal y estabilización del muñón cubital con autoinjerto de tendón palmaris longus: reporte de caso

Abstract

Introduction

Giant cell tumor is a benign but locally invasive neoplasia; presentation at the distal end of the ulna is very rare. In Campanacci grade 3 lesions of the distal ulna, en bloc resection of the tumor is recommended, with or without reconstruction or stabilization of the ulnar stump.

Case report

A 29-year-old woman with a Campanacci grade 3 giant cell tumor of the distal ulna; she was treated with en bloc resection of the tumor, including the extensor carpi ulnaris (ECU) due to being well adhered to the tumor; tendon defect was replaced with a palmaris longus (PL) autograft, to later stabilize the ulnar stump with the reconstructed tendon. Follow-up after 2 years 5 months showed no evidence of tumor recurrence with an excellent functional result and stable ulnar stump.

Discussion

Currently there is insufficient evidence to support the use of a stabilization technique or not, however, it is expected that the treatment carried out will be interesting and avoid possible stability problems of the ulnar stump in the face of wide resections that compromise the extensor carpi ulnaris (ECU).

Level of evidence: IV.
