Abstract
Herein we report the case of a 69-year-old male patient complaining of dry mouth and dry eyes for 8 years. Locoregional examination revealed ocular erythema, angular cheilitis, and atrophic lips. Intraoral examination revealed caries, periodontal disease, and atrophic tongue. The diagnosis hypothesis was primary Sjögren’s syndrome (pSS). Unstimulated salivary flow and minor salivary gland biopsy showed 0.05 mL/minute and chronic sialadenitis (focus score >1), respectively. The patient was referred to an ophthalmologist and the ocular exam confirmed dry eyes (Schirmer test = 5 mm/5 mm, ocular staining score with fluorescein = 4). Serological tests showed: rheumatoid factor = 27.6 IU/mL, Anti-Ro (SSA) = 144.4 U/mL and Anti-La (SSB) = 1.4 U/mL. The final diagnosis was pSS, and the treatment started with pilocarpine 2 mg during 5 months, currently with metotrexato 15 mg/week and folic acid 5 mg/week. This case demonstrated that, although pSS typically affects women, the disease can occur in men and underscores the importance of dentists in the diagnosis of pSS.
