[Facial linear scleroderma associated with neurological abnormalities relating to microangiopathy].

BACKGROUND

Linear scleroderma is a fibrotic disease affecting the skin and sometimes the deeper tissues. We describe a case of scleroderma associated with neurological anomalies not previously reported in the literature.

PATIENTS AND METHODS

A 16-year-old male patient presented in 2009 for hemifacial linear scleroderma. Treatment with methotrexate for 14 months resulted in stabilization of the disease. In 2013, we noted worsening of the patient's skin lesions as well as homolateral ptosis. Head MRI revealed unilateral hemispherical signal abnormalities with T2 hypersignal in the basal gangliaand punctate foci of T2* hyposignal corresponding to microbleeds. In 2014 and 2015, the patient presented three brief episodes of right hemicorpus paresthesia (with temporary aphasia followed by headache during the first episode). The head MRI showed worsening of the anomalies, suggesting progressing cerebral microangiopathy.

DISCUSSION

Clinicians may not always be familiar with the neurological abnormalities associated with localized facial scleroderma even if such abnormalities are not uncommon (their exact prevalence is unknown). Clinical signs vary but, in most cases, the radiological features are calcifications and hyperintense foci of white matter lesions in T2. As far as we are aware, there have been no reports to date of microbleeding as observed in our patient. The worsening with time of these neurological anomalies of unknown origin does not appear to be correlated with the dermatological lesions. It is important for dermatologists be aware of these complications of facial linear scleroderma.
