A Case of Unilateral Submandibular Glandular Aplasia / 대한이비인후과학회지

The congenital absence of the major salivary glands is an uncommon disorder, although it is not always symptomatic. Their etiopathogenesis is poorly understood. Aplasia of the salivary glands may occur either in isolation or in association with other developmental abnormalities. Some authors have reported familial salivary gland aplasia. Aplasia may be partial or total. Severely affected patients suffer from dry mouth and an increased rate of dental decay. Following clinical exclusion of the cause of these symptoms, the diagnosis of submandibular gland aplasia can be confirmed by computed tomography and a Tc-99m pertechnate scintiscan. The authors experienced a case of incidentally detected, unilateral submandibular glandular aplasia in a 38-year old female. So we present this case with review of literatures.

Malignant Myoepithelioma of the Parotid Gland: A Case Report and Review of the Literature / 대한이비인후과학회지

Myoepitheliomas of salivary gland occur infrequently and are generally benign. Malignant myoepitheliomas of salivary gland are extremely rare tumor, and increasing number of case reports have shown that malignant myoepitheliomas may either arise de novo or develop in a pre-existing pleomorphic adenoma. In our case, myoepitheliomas was located in the parotid gland, and tumor cells displayed morphological features of spindle & epithelioid cells. Their clinical behavior by literature seems variable. This case dealt with malignant myoepithelioma of the parotid gland in a 65-year-old man with a relatively favourable course, and was followed up for 2 years and 5 months. In addition, this case illustrates some of the characteristic clinical and pathological features of this rare tumor.

A Case of Isolated Frontal Fungal Sinusitis with Orbital Complication / 대한이비인후과학회지

The most commonly involved sinus of fungal infections is maxillary sinus, followed by sphenoid sinus and ethmoid sinus. On the other hand, the frontal sinus is only occasionally affected. Common pathogenic organisms related to fungal sinusitis are species of Aspergillus, dematiaceous fungi or zygomycetes; however, species of candida are rarely reported. In the invasive fungal sinusitis, orbital invasion, invasion and destruction of the skull base with a fungal meningitis, and fungal osteomyelitis with complete destruction of the maxilla have all been reported. Although these occurrences can not be explained, orbital complications have been reported in the noninvasive paranasal sinus mycosis. The treatment of paranasal fungus ball is primarily by surgical removal. In the past, fungus ball of frontal sinus was approached externally; however, this has been largely replaced with the endonasal endoscopic technique. We experienced a case of frontal fungal sinusitis with orbital complication, which was successfully treated by endonasal endoscopic frontal sinusotomy. In this paper, we report this case with a review of literature.
