11/41. Superficial mucoceles and lichenoid graft versus host disease: report of three cases.

    Superficial mucoceles are subepithelial extravasations of sialomucin that occur at the epithelial-connective tissue interface and are directly related to minor salivary glands. They have been described in association with oral lichen planus and, exceptionally, with chronic graft versus host disease. Three patients who underwent an allogeneic bone marrow transplantation for a chronic myelogenous leukaemia presented multiple superficial mucoceles and an oral lichenoid graft versus host disease.

12/41. Vision impairment as presenting symptom of a sphenoidal mucocele.

    We present a case of a 27-year-old woman with a sphenoid mucocele, presenting with bilateral visual disturbance and pituitary gland dysfunction but without nasal or sinus complaints. We would like to emphasize the importance of early diagnosis and prompt surgical treatment.

13/41. Bilateral parotid voluminous masses: a case report.

    The case of a 75-year-old woman with voluminous bilateral symmetrical masses of the parotid glands is reported, and the literature relevant to the differential diagnosis in bilateral neoplastic and nonneoplastic parotid masses is reviewed. The presurgical workup was based on clinical evaluations, nuclear magnetic resonance imaging findings, and cytologic examination to obtain the differential diagnosis. Benign or malignant tumors were excluded. Surgery was performed for esthetic reasons and in consideration of progressive enlargement of lesions. Histopathologic examination of resected masses revealed benign lymphoepithelial cysts with polyclonal infiltration of lymphoid cells. Serological testing for tuberculosis, cytomegalovirus, human immunodeficiency virus, and Epstein-Barr virus (EBV) and testing using the in situ hybridization technique for the presence of cytomegalovirus and EBV were negative for productive infection or viral replication. A diagnosis of retention cysts was suspected on the basis of presurgical evaluation, histopathological examination, and serologic analysis. In this case, bilateral obstruction of the parotid ducts by a mobile denture probably played the main role in the pathogenesis and development of bilateral parotid retention cysts, because any other specific cause for the pathogenesis was not found with diagnostic tools.

14/41. Acinic cell carcinoma found by recurrence of a mucous cyst in the sublingual gland.

    This case report describes an acinic cell carcinoma found by a recurrence of a ranula in the sublingual gland. A 42-year-old male was admitted to the hospital of the tokyo Dental College with a swelling in his right oral floor but without pain. The lesion was treated by windowing the same day under the diagnosis of a ranula, but the swelling appeared again at the same area eight months after the first operation. A resection was performed, and the specimen was sent to the clinical laboratory for pathological diagnosis. Proliferating serous cells were seen in part of the wall of an exudative mucous cyst. PAS staining was partially positive, and immunohistochemical staining for S-100 protein, lactoferrin, and amylase were also positive in cytoplasmic granules. This report concludes that the pathological diagnosis is beneficial in clarifying the reasons for the recurrence of a benign lesion.

16/41. Submaxillary gland mucocele: presentation of a case.

    The term mucocele is referred to two concepts: the extravasation cysts resulting from salivary glandular duct rupture, with mucin leakage into the surrounding peri-glandular soft tissue, and the retention cysts, caused by a glandular duct obstruction and resulting in a decrease or even an absence of glandular secretion. mucocele can not be considered as a true cyst because its wall lacks an epithelial lining. These lesions are very common in the minor salivary glands (particularly in the labial glands), but are very infrequent in the major salivary glands--including the submaxillary glands. The present study describes a clinical case of a right submaxillary gland mucocele resolved by surgical treatment and reviews the differential diagnosis with other clinical entities.

17/41. Canalicular adenoma of the upper lip mimicking mucocele.

    salivary gland neoplasms are relatively rare. Among the salivary gland neoplasms minor salivary gland neoplasms are often deceptive to the clinician and challenging to the pathologist because of their varied morphology and diverse histopathological pattern. This article documents a case of canalicular adenoma of the upper lip mimicking mucocele and discusses the differential diagnosis of minor salivary gland neoplasms.

18/41. Acinic cell carcinoma on the lower lip resembling a mucocele.

    A 64-year-old woman presented with a 2-week history of an asymptomatic mass involving the lower lip. Histopathological examination showed a well-circumscribed tumour composed of many lobules separated by thin, fibrous connective tissue. Individual lobules were composed of round or polyhedral tumour cells, which had a characteristic finely granular and vacuolated cytoplasm and eccentric hyperchromatic nuclei. Positive staining was observed with periodic acid-Shiff, and immunohistochemistry for cytokeratin, alpha-1 antitrypsin, and S-100 protein resulting in a final diagnosis of acinic cell carcinoma. Acinic cell carcinoma represents a well-established, although uncommon, entity in the classification of neoplasms of salivary gland origin. The parotid salivary gland is the most frequent site of acinic cell carcinoma, whereas the lip is a particularly unusual site. The unusual presentation of this tumour may lead to confusion with a mucocele. Given these findings, we suggest that acinic cell carcinoma should be considered in the differential diagnosis of any mucocele-like mass on the lower lip.

19/41. submandibular gland mucocele: report of two cases.

    submandibular gland mucocele should be remembered in the differential diagnosis of swelling at the submandibular triangle. In the cystic lesion of the submandibular area, the biochemical analysis of aspirated material for amylase should be performed. The cases with submandibular gland mucocele should be treated by removing the lesion with both the submandibular and the sublingual glands.

20/41. Parotid duct mucocele.

    Parotid swelling is a common presentation in ENT clinic. Most of the cases involve pathology of the gland. There are not many reported cases about parotid duct pathology. We describe a case of a large parotid duct mucocele with a calculus. Excision of the mucocele and superficial parotidectomy was performed. The post-operative recovery was uneventful.
