RESUMEN
Sjögren's syndrome is a chronic autoimmune disorder of the exocrine glands with associated lymphocytic infiltrates of the affected glands. Dryness of the mouth and eyes results from involvement of the salivary and lacrimal glands. Up to one-half of affected individuals also develop extraglandular involvement in organs distinct from the salivary and lacrimal glands, including the joints, skin, lung, gastrointestinal tract, nervous system, and kidneys. The disease also occurs in conjunction with other autoimmune disorders, such as systemic lupus erythematosus and rheumatoid arthritis. We report a case of a 76-year-old woman who presented to our department with a swelling on the left cheek. Investigations revealed Sjögren's syndrome as the underlying cause of the facial tumor.
RESUMEN
Benign osteoblastoma is a rare bone tumour characterised histologically by the production of woven bone spicules, which are bordered by prominent osteoblasts. It mainly affects young adults. We report a rare case of benign osteoblastoma of the maxilla in a 7-year-old boy who presented with a painful swelling on the left hard palate. An incisional biopsy was interpreted as osteoblastic neoplasm most suggestive of osteoblastoma. After excision of the tumour there has been no recurrence for 2 years.
