Clinical and Histopathological Aspects of Salivary Gland Tumors: A Review

A presumptive clinical diagnosis of salivary gland tumor can usually be made by taking an accurate history, performing a careful clinical examination, and utilizing essential radiographic and sialographic aids. Once a tumor is identified, differential diagnosis between benign and/or malignant involvement, and the exact tumor type becomes more formidable, frequently requiring histological diagnosis. Since optimum treatment is dependent upon an accurate differential diagnosis and surgical management according to tumor type, the clinical and histological aspects of salivary gland tumors are reviewed. A thorough knowledge of these characteristics allows an accurate diagnosis and provides the indications for proper treatment

The Nature of Bone Resorption and Formation in Normalcy and Disease

Classically, Howship\u27s lacunae and osteoid seams or tissue have been used for microscopic identification of sites of bone osteoclastic and osteoblastic cell activity respectively. Recent transmitted light and blue light fluorescence microscopic study of fresh, undemineralized, specially stained and tetracycline labeled bone specimens have supported this use of these parameters of bone resorption and formation. Reports that the osteoclast is not required for bone resorption are evaluated here; it is concluded that no evidence exsists for resorption of bone tissue without osteoclasts. This does not apply to the perilacunar phenomena observed in certain well-defined situations

Sjögren\u27s Syndrome In Childhood: Report of a Case

This report documents a rare case of Sjögren\u27s Syndrome which began in a child with juvenile rheumatoid arthritis at the age 10 years, followed by the symptoms of xerostomia with intermittent salivary gland swelling 15 months later. By age 12 the patient had developed keratoconjunctivitis sicca. Variations in the intensity of each component of Sjögren\u27s syndrome were noted to be independent of each other

Respiratory implantation cyst of the mandible following orthognathic surgery

A cyst following implantation of respiratory epithelium during surgical procedures has been documented only rarely. A variety of names have been attached to this lesion: respiratory mucocele, respiratory implantation cyst, surgical ciliated cyst, and surgical (implantation) cyst. In seven prior case reports, the interval between the initiating surgical procedure and diagnostic biopsy of the resultant well-circumscribed radiolucency and histopathological demonstration of distinctive pseudostratified ciliated columnar epithelial lining has varied from 4 to 40 years. In the case reported here, chin augmentation used “residual maxillary bone” as the donor tissue and likely transplanted sinonasal mucosa into the mandible during orthognathic surgery, resulting in a painful anterior mandibular cyst lined by respiratory epithelium that was ablated 16 years later
