Aim: Paraspinal desmoid tumors are rare and only few cases have been reported in the literature. This report describes a case of successful excision of a parasacral desmoid tumor in a 34 years old female. Methods: The patient presented with a tender mass over her right sacral region. Radiological examination with CT and MRI demonstrated two adjacent well circumscribed masses measuring 4 × 3 and 2.5 × 3 cm, in the subcutaneous fat of the right paravertebral region. At surgery the patient underwent a wide excision of the lesion, and two tumor masses were dissected away from the gluteus and the multifidus muscles. Histopathologic examination of the specimens confirmed the diagnosis of a desmoid tumor. Results: After surgical resection without adjuvant therapy, the patient is recurrence free after 36 months. Conclusions: Despite their benign microscopic appearance, and their insignificant metastatic potential, the tendency of desmoid tumors for local infiltration is potentially significant causing deformity, morbidity and even mortality, especially when present at the paraspinal area, due to the pressure effects to the close neural structures and the spinal canal as well. Early detection of the neoplasm is crucial, in order to achieve radical excision of the neoplasm before it penetrates vital structures. © 2008 Springer-Verlag. |
