    Oral medicine case book 52: pleomorphic adenoma of the upper lip
    (South African Dental Association (SADA), 2013) Stander, Suzette; Mulder-Van Staden, Sune; Cheung, Tik; Dreyer, Wynand P.; Afrogheh, Amir; Mohamed, Nadja
    A 46-year old female presented at the Oral Medicine Clinic complaining of a large and painless swelling of her upper lip. The lesion had slowly enlarged over the past year and was causing an increasing aesthetic and speech impairment. Her medical history revealed nothing of note. Extra-orally, the patient presented with a swelling involving the right side of the upper lip and extending from the right alar of the nose, to the right commissure (Figure 1). The intra-oral examination revealed a firm and well circumscribed mass in the upper right labial mucosa, opposite the upper second incisor, canine and first premolar. The mass was approximately 2x3 cm in size and the overlying mucosa was of normal consistency and colour for the region (Figure 2). A fine needle aspiration biopsy (FNAB) of the mass was performed (Figure 3).

    Oral medicine case book 53: radiation - induced xerostomia
    (South African Dental Association (SADA), 2013) Cheung, Tik; Peck, Mogammad T.; Dreyer, Wynand P.
    A 76-year old male presented at the Oral Medicine Clinic, complaining of a persistent feeling of a dry mouth, subsequent to having undergone surgery, chemotherapy and radiation therapy for nasopharyngeal carcinoma, 18 months previously. Other than the cancer, he had no systemic problems of note and was otherwise in good physical health. Upon further questioning, the patient reported that the dry mouth condition was affecting his quality of life and that he was losing weight due to difficulty in eating. He further emphasised that his mouth felt dry within five minutes of rinsing his mouth with the palliative agents suggested by his dentist and oncologist. The regimen he followed to relieve his symptoms included glycerine BP oil, Candacide© (a nystatin containing product), Biotene© mouth spray and mouthrinse (these products contain lactoperoxidase, glucose oxidase, lysozyme and lactoferrin), Orbit© sugar free gum and an increased frequency of water intake.
