Polymorphous low-grade adenocarcinoma (PLGA) is a distinctive salivary gland neoplasm with a propensity to arise from minor salivary glands, particularly of the palate. Reports of PLGA have increased with the establishment of specific histopathological criteria characterizing the PLGA, but there are only a few reports of major salivary gland origin. PLGA shares histological features with adenoid cystic carcinoma, so histopathologic diagnosis is essential and immunohistochemistry is an important tool when making differential diagnosis. The treatment of choice is wide surgical excision, and long-term follow up is necessary to evaluate local recurrences. We herein report a case of PLGA arising in a submandibular gland with a review of the relevant literature. Korean J Otorhinolaryngol-Head Neck Surg 2014;57(11):778-82
Malignant otitis externa (MOE) is an aggressive and fatal disease that can spread along the soft tissues and skull base. In most case, it is caused by Pseudomonas aeruginosa, and fungus is rarely involved. The clinical fea-ture of fungal MOE is very similar to that caused by bacteria, and the diagnosis is only confirmed by deep tissue biopsy, not by swab culture. Therefore, the diagnosis is often difficult to establish. In individuals who initially do well on antimicrobial therapy but subsequently recrudesce or who are unresponsive to appropriate antimicrobial treatment, clinician’s suspicion of fungal MOE is important not to delay the definite treatment. We experienced a case of 70-year-old man on hemodialysis treatment, who had severe right otalgia and headache for several weeks. He initially did well on antimicrobial treatment but subsequently experienced recrudescence. Through deep tissue biopsy, he was diagnosed as fungal MOE.
Tuberculosis of the upper respiratory tract is an uncommon disease, and nasopharynx is rarely involved without evidence of active pulmonary or systemic tuberculosis. The incidence of tuberculosis has decreased because of anti-tuberculous chemotherapy. Recently, we experienced 4 cases of nasopharyngeal tuberculosis. Yet the management strategy of extra-pulmonary tuberculosis is controversial but a medical therapy with anti-tuberculous drugs is usually effective, and surgical therapy is rarely needed. We report our findings in these primary nasopharyngeal tuberculosis patients with a review of the relevant literature.
Solitary tracheo-bronchial papillomas are rare benign neoplasms. They are subclassified into three categories by variety of histological cell types including squamous cell papilloma, glandular papilloma and mixed squamous cell and glandular papilloma. Of these types, mixed squamous cell and glandular papilloma is extremely rare and a few cases reported in Korea. We describe a case of mixed squamous cell and glandular papilloma arising from the upper trachea with a review of the relevant literature. To our knowledge, this is the first reported case of upper tracheal mixed squamous cell and glandular papilloma in Korea
The parotid gland is well affected by the inflammatory process. Acute suppurative parotitis may originate from a septic focus in the oral cavity, but acute suppurative parotitis in the pediatric population is uncommon. Salivary duct calculi such as Stenson’s duct calculi is the one of possible causes of suppurative parotitis. Because the presence of significant complicated conditions in children, prompt diagnosis and treatment such as surgical removal is needed. We have experienced a case of right supprative parotitis with Stensen’s duct sialolith in 2-year-old male. The right stenson’s duct calculi was diagnosed following axial computed tomography scan. The patient was treated with antibiotic therapy and sialolithotomy was done via intraoral approach. We report this case with a review of the literature.
Epithelial-Myoepithelial carcinoma (EMC) is rare salivary gland neoplasm with a propensity to arise from major salivary gland, particularly of the parotid. EMC shows a characteristic biphasic population of epithelium and myoepithelium but shows various cytologic and histologic features, so this low grade malignancy can cause diagnostic confusion during workup and also frequently be misdiagnosed as other high grade salivary malignancy. Therefore histopathologic diagnosis is essential and immunohistochemistry is an important tool when making differential diagnosis. The treatment of choice is wide surgical excision, and long-term follow up is necessary to evaluate local recurrences. We herein report a case of EMC arising in a sublingual gland with a review of the relevant literature.
Hypertrophy of salivary gland was developed by sialadenitis, sialolithiasis, autoimmune diasease and other tumorous conditions. Mikulicz’s disease has been used to describe symptomless hypertrophy of the salivary gland and lacrimal gland. In the past, it was thought that Mikulicz’s disease is included within the diagnosis of Sjögren’s syndrome. However, Mikulicz’s disease represents Immunoglobulin G4 (IgG4)-related hypertrophy of salivary gland and lacrimal gland by an elevated level of IgG4 in the serum of the patient and good responsiveness to glucocorticoid, eventually leading to recovery of gland function. We have experienced a case of IgG4-related sialadenitis and dacryoadenitis with bilateral hypertrophy of parotid, submandibular and lacrimal glands. We report this case with a brief review of the literature.
Isolated retropharyngeal hematoma following blunt trauma is relatively rare and difficult to diagnosis early. Etiologies of retropharyngeal hematoma include trauma, infection, hemorrhagic diathesis, parathyroid adenoma hemorrhage, and foreign body ingestion. Because life-threatening airway obstruction can develop hours or days after trauma, the rapid assessment and treatment may be needed. A 49-year-old man developed dyspnea following car accident and was diagnosed with retropharyngeal hematoma. The patient underwent emergent hematoma evacuation procedure and tracheotomy. Here we report a case of isolated hematoma in retropharynx with review of literature.
Toxoplasmosis is a common cause of cervical lymphadenopathy and histopathological specimens needed for establishing diagnosis, the diagnosis of toxoplasmic lymphadenopathy should always be confirmed by isolation of the parasite or by serologic test. The use of fine needle aspiration cytology (FNAC) in the investigation of lymphadenopathy is minimally invasive and has become an worldwide acceptable technique. We compare the results of FNAC and excisional biopsy in seropositive toxoplasmic lymphadenitis, to determine the importance of excisional biopsy and serologic test for toxoplasmosis. Materials and Methods:A retrospective chart review of 12 patients (7 underwent only FNAC, 4 underwent both FNAC and excisional biopsy, remaining 1 was only excisional biopsy case) was carried out. Results:Only 36.3% of FNAC group match toxoplasmic lymphadenitis, but excisional biopsy group is reliable to toxoplasmic lymphadenitis. Conclusions:When FNAC result of solitary cervical lymphadenitis is obscure, the excisional biopsy and serologic test for toxoplasma is always helpful for establishing diagnosis of toxoplasmosis.
