Introduction:
Near 10 to 20% of patients with myositis have another systemic, sometimes inaugural, disease.
Case Report:
A 48-year-old woman was admitted with progressive hypoesthesia in V2 and V3 areas on both sides, difficulties to chew and swallow and then, proximal and axial muscular deficiency, with weight loss. Brain MRI showed gadolinium-enhanced trigeminal nerves and biological tests revealed anti-SSA and anti-Pm/Scl antibodies and a grade IV in Chisholm scoring system on the labial salivary gland biopsy. Neurophysiological studies revealed a myogenic pattern on tibialis anterior muscles and a muscle biopsy confirmed the diagnosis of polymyositis.
Conclusion:
The diagnosis of primitive Sjogren's syndrome was suspected because of the association of bilateral trigeminal neuropathy and anti-SSA and anti-Pm/Scl antibodies.
