    Mucoepidermoid carcinoma ex pleomorphic adenoma: A rare diagnostically challenging entity
    (Elsevier, 2022) Titinchi, Fadi; Sallies, Moegamat; Wu, Hue-Tsi
    Mucoepidermoid carcinoma (MEC) arising in pleomorphic adenoma (PA) is an extremely rare entity. Involvement of minor salivary glands by this entity has only being described twice previously. We report on a diagnostically challenging case in an 18 year old male with a large mass in the junction of the hard and soft palates that has been present for 12 months. Both cytology and incisional biopsy were inconclusive and indicated benign mixed tumour. Upon excision of the tumour with a 5 mm clear margin, histology demonstrated PA that has been replaced by small nests and cribriform islands of high-grade MEC with 13 mm of invasion beyond the original PA capsule. The tumour was composed of mostly intermediate-type cells with up to 7 mitoses per 10 high power fields. The tumour cells were positive for cytokeratin (CAM 5.2) and S100. Due to the high-grade nature and focal positive posterior margin of the resected specimen, adjuvant radiotherapy was administered. In conclusion, this case highlights the need to consider rare entities such as mucoepidermoid carcinoma ex pleomorphic adenoma in atypical cytological and histological findings. Moreover, it underlines the need to manage lesions with unconfirmed histological diagnosis with wide excision margins to avoid having involved margins post resection.

    Osteopetrosis complicated by osteomyelitis of the maxilla: A rare case report and review of the literature
    (Wroclaw Medical University, 2020) Sallies, Moegamat; Titinchi, Fadi; Morkel, Jean A
    Osteopetrosis is a rare hereditary bone disorder that results in an increase in bone density due to gene mutations and osteoclastic dysfunction. This may lead to cranial nerve compression, bone fractures and osteomyelitis. Osteomyelitis of the maxilla is rare even in osteopetrosis patients.

    The impact of COVID-19 on maxillofacial and oral surgery service in a tertiary hospital in South Africa
    (University of the Western Cape, 2024) Sallies, Moegamat; Morkel, J.A.
    COVID-19, the coronavirus disease of 2019 caused by the SARS-CoV-2 (SC2) virus, imposed a burden on healthcare institutions worldwide. On 5 March 2020, the first confirmed COVID-19 case was identified in South Africa. On 23 March 2020, the president of the Republic of South Africa, President Cyril Ramaphosa, announced a state of disaster along with a national lockdown which was initiated on midnight, 26 March 2020 (Parker et al. 2020). The lockdown restrictions had numerous effects on the healthcare system. Maxillofacial and oral surgery which is a surgical specialty of dentistry with a strong footprint in medicine was also affected (Yadav et al. 2019). Since the Maxillofacial and Oral surgery departments were not on the front line of the struggle, elective surgeries were cancelled and postponed as the situation developed to make more beds available and offer material and human resources for the evolving health emergency (Saibene et al. 2020). This study aimed to document how the COVID-19 pandemic impacted the surgical services rendered under general anaesthesia at the Department of Maxillofacial and Oral Surgery at Tygerberg Oral Health Centre, by comparing two consecutive intervals, one period occurring before the pandemic (26 March 2019 - 21 September 2019) and the other during the pandemic (26 March 2020 - 21 September 2020).
