    Oral medicine case book 49: plasmablastic lymphoma
    (South African Dental Association (SADA), 2013) Stander, Suzette; Holmes, Haly; Dreyer, Wynand P.; Afrogheh, Amir; Mohamed, Nadja; Hille, Jos; Osman, Nuraan
    A 25-year-old male patient presented at the Oral Medicine Clinic with a painful bleeding lesion on the palate causing him discomfort during speech, mastication, and sleep. The lesion started approximately five months earlier as a small growth that gradually increased in size. The patient was rather vague about his medical history and habits but he did reveal that he smoked two cigarettes per day as well as using cocaine, a habit for which he was receiving therapy, for drug-induced hallucinations, at a local psychiatric hospital. He was not aware of any other medical conditions or allergies. The extraoral examination revealed nothing of note, however, on intraoral examination a large and firm pedunculated exophytic soft tissue mass was seen on the hard palate. It covered a large portion of the hard palate extending from the back of the upper incisors posteriorly onto the anterior part of the soft palate and into the right vestibule. It extended laterally to the gingival margins of all the teeth in the first quadrant, resulting in an appearance of gingival hyperplasia. The growth had an erythematous appearance with surface patches of necrosis and other areas that easily bled on touch (Figure 1).

    A 33-year-old female of African descent was referred to the Oral Medicine Clinic from a neighbouring rural clinic. The patient presented with painful nodular lesions on her gingivae and hard palate, having noticed the enlarging lesions two months earlier when they started to impair her speech and mastication. She reported that she had been diagnosed with HIV infection two years earlier and had been on antiretroviral medication for the past eleven months. The patient had a recent history of pulmonary tuberculosis and cryptococcal meningitis. At the time of the initial examination, her CD4 count was 230/µl (normal levels in adults: ±1000 cells/µl) and the laboratory report indicated viral load failure, i.e. the patient was no longer responding satisfactorily to the HAART therapy.

    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 57: Orofacial granulomatosis
    (SADA, 2014) Mulder-Van Staden, Sune; Holmes, Haly; Dreyer, Wynand P.; Afrogheh, Amir
    A 17-year old female presented at the Oral Medicine Clinic with the complaint of persistent swelling of the upper lip and anterior attached gingiva, causing her discomfort when eating and talking. The swelling started approximately ten months earlier. At the time she was seen by her physician who prescribed an antibiotic that gave mild symptomatic relief, but no clinical resolution. She was also seen by an oral hygienist on three occasions with no improvement of the gingival swelling. The patient also reported that she had been diagnosed with depression and type 2 diabetes approximately two years ago and was currently using Citalopram (a selective serotonin reuptake inhibitor) and Glucophage (metformin hydrochloride, an anti-hyperglycemic drug). Extra-oral examination revealed a firm, swollen and superficially cracked upper lip with a red granular appearance. No enlarged cervical lymph nodes could be palpated. Intra-orally, the anterior maxillary and mandibular gingivae were hyperplastic and erythematous, with a granular surface (Figures 1, 2 and 3). The differential diagnosis included contact allergy and granulomatous disease, including mycobacterial infection.

    Oral medicine case book 61: Oral malignant melanoma
    (South African Dental Association, 2014) Mosalleum, E.; Afrogheh, Amir; Dreyer, Wynand P.; Schneider, J.W.
    A 45-year old male patient presented at the Oral and Maxillofacial Clinic, Tygerberg, with a pathological fracture of the left mandible following an extraction. The medical records of the patient revealed a history of multiple myeloma that was treated with Aredia (pamidronate disodium, an intravenous form of bisphosphonate), cyclophosphamide (an alkylating agent) and dexamethaxone (an anti-inflammatory and immunosuppressant drug). An orthopantomograph revealed osteonecrosis and pathological fracture of the left mandible, thought to be due to the earlier biphosphonate administration. The patient received conservative management for the osteonecrosis and was stable at the time of the publication, (19 months after the initial presentation with the pathological fracture).

    Oral medicine case book 67: Oral manifestations of Evans syndrome: a presenting feature of HIV infection?
    (South African Dental Association, 2015) Ranchod, S.; Jeftha, Anthea; Meyer, M.; Dreyer, Wynand P.;
    A 19 year old female presented with spontaneous intra - oral bleeding of two days duration. The patient reported that she was, until recently, in good general health and also that she had an uncomplicated parturition three years ago. She recently started noticing blood in her stools and felt increasingly lethargic. There was no history of trauma or intra-oral intervention that may have initiated the bleeding. The clinical examination revealed marked pallor of the facial skin and multiple small petechiae were seen on both of her forearms. The intra-oral examination identified marked halitosis and multiple haemorrhagic lesions with a variable appearance, being plaque-like on the lip, nodular on the tongue and fungating and exophytic on the palate and in the retromolar regions. Even delicate manipulation of the tissues produced profuse bleeding.

    Oral medicine case book 68: Oral ulceration caused by rifampicin-resistant tuberculosis
    (South African Dental Association, 2015) Peck, Mogammad T.; Hille, Jos; Snyman, A.; Dreyer, Wynand P.
    A 53-year old female was referred by her local general medical practitioner to an oral medicine specialist for the management of a persistent ulcer on the left side of her tongue. The lesion had been present for at least three months and was not responding to treatment by topical antiseptic agents. The earlier removal of a molar in close proximity to the lesion, in an attempt to exclude the possibility of traumatic ulceration, had also yielded no beneficial effects. Upon examination, the patient appeared clinically healthy but presented with a history of emphysema due to chronic cigarette smoking. The emphysema was currently being managed by oral inhalation steroids. Even though smoking cessation had previously been advised, she failed to comply and was currently still smoking more than 10 cigarettes per day.

    A 25-year-old female was referred to the Haematology Unit at Tygerberg Hospital for further management of a rapidly expanding and large submandibular mass which on fine needle aspiration was suggestive of lymphoma . Five months earlier she had been diagnosed with pulmonary tuberculosis and was confirmed to be HIV positive with a CD4 count of 17. She was placed on anti-retroviral (ARV) and antituberculous therapy (the ARV therapy included efavirenz, emtricitabine and tenofivir). Her CD4 count, at the time of the current consultation, was 204 and the viral load was suppressed. Lumbar puncture was normal. Significant clinical findings were a large right submandibular mass and right cervical and axillary lymphadenopathy. The submandibular mass was removed and submitted for histological examination.
