Some authors consider the disease a variant of mor- phea because the histologic changes are identical to deep scleroderma.2 The possible etiologies include sympathetic denervation, trauma, vascular malformations, immunologic abnormality, heredi- tary disease, or infection by a slow virus.3 To our knowledge, this is the first report of a young patient with a possible association between Parry-Romberg syndrome and thoracoscopic sympathectomy.
Theoretically, thoracoscopic sympathectomy may cause 2 of the aforementioned etiologies of Parry- Romberg syndrome: sympathetic denervation and trauma. Thoracoscopic sympathectomy is a surgical technique for the treatment of palmar hyperhidrosis.
The operation ablates the upper thoracic sympa- thetic nerve ganglions responsible for nerve stimu- lation of the sweat glands of the upper limbs. The most significant complication is Horner’s syn- drome, which results from injury to the stellate sympathetic ganglion.7 In a summary of sympa- thectomies in 67 children and adolescents, compli- cations included Horner’s syndrome in 1 patient (1%) and varying degrees of compensatory sweat- ing in 30 patients (45%).8 Despite the evidence from animal studies that sympathectomy can result in facial atrophy, to our knowledge, there were no previous reports of such an association in humans.
