Sjögren's syndrome (sicca complex).
A case of sicca complex Sjögren's syndrome in a 41-year-old woman is presented. Symptoms related to xerophthalmia and xerostomia were severe but, ironically, served to confuse the clinical impressions of medical personnel managing this patient, resulting in a diagnostic dilemma. Biopsy of a labial minor salivary gland followed by histopathologic examination of the tissue provided invaluable information which, together with the clinical picture, aided in the establishment of the delayed diagnosis.
