However, a careful patient clinical assessment is usually sufficient for a correct diagnosis in the large majority of cases by considering some important findings: histopathological alterations of salivary glands and specific autoantibody pattern (anti-RoSSA/LaSSB) of pSS are rarely found in MC patients; conversely, HCV infection, cutaneous leukocytoclastic vasculitis, and visceral organ involvement (renal, liver) are seldom recorded in primary Sjögren's syndrome (Fig. 7). Here, SSB is linked to peeling skin syndrome.
