ABSTRACT
Ameloblastic carcinoma is a highly malignant tumour and requires aggressive treatment. This case report describes an aggressive ameloblastic carcinoma that infiltrated the mandible. Mandibulectomy with right functional radical neck dissection and left supra omohyoid dissection was followed by primary reconstruction with a single free vascularised fibula flap. The post-operative course was uneventful. The 2 year regular follow up revealed no signs of recurrent tumour or metastasis. Future reporting of this rare condition is encouraged in lieu of limited information in its clinical course and prognosis.
ABSTRACT
Although osteosarcoma is the most common primary bone cancer, the incidence in head and neck bony structures is extremely low. As the surgical treatment requires a wide margin excision, the operation usually will be very challenging especially if it involves midline structures. We report a case of a young gentleman who had a bony growth over the epicenter of the hard palate which rapidly occupies the whole oral cavity within 6 months duration. The outline of management is discussed.
ABSTRACT
Histopathological and ultrastructural features of a case of pseudocyst extravastation mucocele lesion located in the lower lip of an 18 yearold Malaysian female is presented. Complete surgical excision of the lesion with associated minor salivary glands was done. The specimenwas processed for routine histopathology and transmission electron microscopy (TEM) for ultrastructral studies. The lesion revealed pooling of mucin infiltrated with inflammatory cells and walled by a rim of granulation tissue. The underlying salivary lobules showed varying degrees of chronic sclerosing sialadenitis. Ultrastructural features revealed multiple membrane bound electron lucent mucus granules with varying diameter, duct cells with few microvilli. Desmosomes, tonofilaments and myoepithelial cells were prominent. There were also dilatation of the rough endoplasmic reticulum (RER)and presence of multiple electron dense granules
