Adenoid cystic carcinoma(ACC) is one of the common malignant tumor of the major and minor salivary glands. ACC arising from the larynx is relatively rare(less than 1% of laryngeal malignant tumors) and only about eighty cases have been reported in the English literature. Definite diagnosis of these lesions is made only from a histological analysis, because findings and symptoms are non-specific. The diagnosis progresses very slowly, therefore it often presents at an advanced stage with regional and distant metastasis. Here, we present one case of ACC of the supraglottic region with a review of literature.

기관이나 주기관지에서 발생한 선양 낭포암은 서서히 진행하며 조기진단이 어렵고 특징적인 임상적 증상이나 소견이 없어 만성적인 호흡기 질환과의 감별 진단이 힘들어서 질환이 상당히 진행된 후에야 발견되는 수가 많고 원격전이가 많으며 또한 대부분 재발하는 특성이 있으므로 치료후 10년이상의 세심한 추적관찰이 필요하다. 저자들은 선양낭포암이 좌측 주기관지에 발생한 58세 여자 환자와 기관후벽에 발생한 25세 여자 환자를 각각 경험하였기에 보고하는 바이다.

림프조직은 비인두 부위에서 Waldeyer's ring의 일부조직으로 tonsil을 이루며 정상적으로 존재한다. 이러한 림프조직이 임상적인 증상을 나타낼 정도로 과증식한 것을 'Adenoid vegetation or Adenoids'라고 이른다. 아데노이드는 일반적으로 유년기에 발생하며 $2\~12$세때 특징적인 증상을 보인다. 사춘기시기에 이르면 절대적인 아데노이드 크기 감소와 주변의 비인두의 성장으로 인한 상대적 크기 감소가 나타난다. 그리하여 성인이 되면 아데노이드는 퇴화된 상태로 변하게 된다. 아데노이드는 구호흡의 주요한 원인 중 하나이며, '아데노이드 얼굴'이라는 특징적인 안면형태를 야기한다고 알려져 있다. 아데노이드에 의한 구호흡이 안면 형태와 치열에 영향을 미칠 수 있다는 주장은 오래 전부터 제기되고 있으나, 여러 가지 복합적인 원인으로 이들간의 상호연관정도를 정확히 알기가 어려웠다. 이에 본 연구에서는 정상 교합 아동에서의 골 연령에 따라 아데노이드와 악골 크기의 정상치와 성장변화량을 제시하고 이들간의 상관관계를 알아보았으며 다음과 같은 결과를 얻었다. 1. 골 연령에 따른 남녀별 계측항목의 평균과 표준편차를 얻었다. 2. 같은 골연령을 비교시 남자는 여자보다 약 2년 가량 성장속도가 느렸다. 3. 비인두의 height과 depth는 남자에서는 CVMI 1과 2 때 많은 성장을 보이고, CVMI 4 이후에서는 성장을 보이지 않았으며, 여자에서는 모든 골 연령에서 유사한 정도의 성장이 나타났다. 4. 비인두의 상대적 면적은 남자에서 CVMI 1에서 2로 이행되는 시기에 유의한 증가를 보였다. 5. 비기도의 상대적 면적과의 상관분석에서 남녀 모두에서 아데노이드 항목중에서는 Ad2와 관련된 항목과 uppe pharynx가 높은 상관관계를 보였으며, 치열궁과 관련된 항목중에는 상$\cdot$하악의 견치간 너비, 상악의 대구치간 너비, 구개정 높이가 상관관계가 있었다.

Background/Objectives: Adenoid cystic carcinoma is the second most common salivary carcinoma. It occurs commonly in the submandibular gland, sublingual gland and minor salivary gland. Local recurrence and distant metastasis are the leading cause of death. The aim of this study was to evaluate long-term oncologic outcomes of patients with head and neck adenoid cystic carcinoma focusing on distant metastasis. Materials & Methods: We retrospectively studied 39 patients who were diagnosed with and treated for adenoid cystic carcinoma of the head and neck from December 1996 to May 2018. The clinicopathologic characteristics of patients such as age, sex, primary site and TNM stage, and treatment methods, recurrence and distant metastasis after treatment, survival rate, and treatment method for recurrence were analyzed. Results: Of 39 patients, 18 were males and 21 were females, and the mean age was $5.9{\pm}14.4$ (28-89) years. The most common primary site was oral cavity (12 cases), and followed by sino-nasal cavity (11 cases), parotid gland (5 cases), and etc. For treatment, 17 patients underwent surgery alone, 16 received surgery with postoperative radiation therapy, and 3 patients received radiation therapy only. Three patients refused any further treatments. Recurrence occurred in 15 patients. The most common site of recurrence was the lung. The mean time to recurrence was 31.7 months. The 5 and 10 years' overall survival rate was 79.3% and 74%, respectively. The 2 and 5 years' overall survival rate was 69.6% and 62.6% in patients with distant metastasis. Conclusion: Distant metastasis is an important prognostic factor in adenoid cystic carcinoma, and eventually one third of patients have distant metastasis, especially in the lung. An appropriate treatment for lung metastasis is necessary because some patients with pulmonary metastasis survive for a quite long time.

A 22-year old female visited CNUH due to palpable neck mass. Cytologic examination of a fine needle aspiration was performed and the result was Pap class II. Routine chest x-ray shows solitary pulmonary nodule. For rule-out malignancy, FNA at neck mass was repeated and pathologic finding was dysplasia. She was admitted to MI department for evaluation of solitary pulmonary nodule and percutaneous needle aspiration was done. Pathologic diagnosis was adenoid cystic carcinoma. Thereafter, the lesions were treated by excisional biopsy of submandibular gland mass with left supraomohyoid neck dissection and wedge resection of right lower lobe at ENT department and thoracic and cardiovascular surgery department, respectively. Final diagnosis was adenoid cystic carcinoma arising in submandibular gland with solitary lung metastasis. According to TMN staging system, surgical staging is stage IV of T2N0M1. Clinical follow-up to postoperative 13 months in this case showed that she is alive and well without evidence of recurrence.

After analysis according to age, sex, site of origin, nodal involvement, perineural invasion. histopathology and treatment modality. authors had reached the following conclusion about the 28 cases of adenoid cystic carcinoma of the salivary gland, which were, histopathologically, diagnosed at Yonsei University Severance Hospital and Yongdong, Severance Hospital during the 8-year period from Apr. 1983 to Mar. 1991. Among the 28 cases, 13 were females and 15 were males, which implies that there isn't any sigificant distinction of gender. The age range was 24 years to 69 years with a mean age of 49 years, and the most common site of origin in order was 6 cases(21.4%) of maxillary sinus, 5 cases(17.8%) of submandibular gland, each 4 cases(14.4%) of parotid gland, palate, 3 cases(10.4%) of nasal cavity and each 2 cases(7.1%) of mouth floor, nasopharynx with each one case(3.6%) of buccal mucosa and retromolar trigone. With clinical staging by UICC, the 5-year survival of adenoid cystic carcinoma was 100% in stage I and II, 87.5% in stage III. In stage IV, all of the patient were died within 3 years. We have known that the prognosis was poorer in following cases; the cases with higher clinical stage, primary site other than the major salivary gland especially maxillary sinus and positive neural or nodal invasion.

Objective: To investigate the effects of the long-term use of a maxillary protraction facemask with miniplate (FM-MP) on pharyngeal airway dimensions in growing patients with cleft lip and palate (CLP). Methods: The study included 24 boys with CLP (mean age, 12.2 years; mean duration of FM-MP therapy, 4.9 years), divided into two groups according to the amount of A point advancement to the vertical reference plane (VRP): Group 1, > 4 mm; Group 2, < 2 mm; n = 12/group. After evaluating the skeletodental and airway variables using lateral cephalograms acquired before and after FM-MP therapy, statistical analyses were performed. Results: Group 1 showed greater forward and downward displacements of the posterior maxilla (posterior nasal spine [PNS]-horizontal reference plane [HRP]; PNS-VRP), greater increase in ANB, more forward tongue position (tongue tip-Pt vertical line to Frankfort horizontal plane), and greater increase in the oropharynx (superior posterior airway space [SPAS]; middle airway space [MAS]) and upper nasopharynx (PNS-adenoid2) than did Group 2. While maxillary advancement (A-VRP and PNS-VRP) correlated with increases in SPAS, MAS, and PNS-adenoid2, downward displacement of the PNS (PNS-HRP) correlated with increases in SPAS, MAS, PNS-adenoid1, and PNS-adenoid2, and with a decrease in vertical airway length (VAL). Mandibular forward displacement and decrease in mandibular plane correlated with increases in MAS. Conclusions: FM-MP therapy had positive effects on the oropharyngeal and nasopharyngeal airway spaces without increases in VAL in Group 1 rather than in Group 2. However, further validation using an untreated control group is necessary.

This is a report of adenoid cystic carcinoma occurred in the palate in 30-year-old patient with a complaint of exophytic mass. The authors diagnosed it as adenoid cystic carcinoma by the clinical examination, radiographic findings and histopathological findings. The obtained results are as follows: 1. In clinical examination, asymptomatic exophytic mass of palate was observed. 2. In radiographic findings, soft tissue mass infiltrated the left maxillary sinus, nasal cavity, infraorbital fossa, hard palate, pterygopalatine fossa and pterygoid plate, and enhanced soft tissue mass was also observed in CT. 3. In histopathological findings, tubular and solid patterns of glandular structures were observed and the infiltration of tumor cells into the nerve fibers was also observed. 4. Two years after radical surgery, radiation therapy and chemotherapy, the perineural spread to orbital area was observed. 5. Much longer follow-up than 5 years is needed for early diagnosis of recurrence and distant metastasis.

Although adenoid cystic carcinoma (ACC) of the lacrimal gland is a rarely encountered orbital tumor, it invades intracranially more frequently than carcinomas of other glands in the head and neck. A 52-year-old man underwent orbital exenteration and resection of intracranially extended tumor via a fronto-orbito-zygomatic approach in combination with a transfacial approach. Histopathologically, the tumor showed perineural, vascular, and lymphatic invasion. Additionally, he received radiotherapy (60 Gy) and adjuvant systemic cisplatin and 5-fluorouracil chemotherapy due to residual tumor in the orbit and systemic metastases (lung, ribs, and spines). He was free of progression and recurrence at 6 months after treatment. The authors report a case of skull base invasion by an ACC of the lacrimal gland to remind neurosurgeons planning intervention that this disease shows a tendency to invade intracranially.

Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of these tumors occurs in the minor salivary glands. especially mucosa of the hard palate. The authors experienced the patients, who complained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary glands, and obtained results were as follows : 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic exarnminations, soft tissue masses were observed with invasion to adjacent structures, and moderate defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic exarnminations, dark-stained, small uniform basaloid cells in the hyaline or fibrous stroma were observed as solid and cribriform patterns, respectively.
