Primary pulmonary adenoid cystic carcinoma diagnosed by transthoracic fine needle aspiration cytology
Nuwal Paras,Dixit Ramakant,Sharma Sidharth
Journal of Cytology , 2008,
Abstract: Adenoid cystic carcinoma (ACC) is an uncommon tumor that very rarely affects the lower respiratory tract and lung parenchyma. Fine needle aspiration cytology (FNAC) of primary pulmonary ACC has been rarely described. We report here a 32 year-old female with peripheral ACC, diagnosed by percutaneous transthoracic FNAC. The cytological diagnosis was further confirmed by histological examination of the biopsy specimen.

Abstract: Primary adenoid cystic carcinoma of the cervix is a rare condition. It is a rare variant of adenocarcinoma and is mostly seen in postmenopausal women. Here we report a case of primary adenoid cystic carcinoma of uterine cervix.

Abstract: Introduction: The sphenoid adenoid cystic carcinoma is a rare malign neoplasm, in the head and neck and when located in the paranasal sinuses, it is formed in the minor salivary glands. It grows slowly and is characterized by a large invasion of the adjacent tissues, and also has a large capacity of metastasis. The surgery associated with post-operative radiotherapy is used as treatment. Objective: To describe a case of sphenoid sinus adenoid cystic carcinoma in a male, black, 62 year patient. Case Report: N.L.B., 62 years of age, male, had bloody rhinorrhea for 6 months associated with bilateral nasal obstruction. The nasofibroscopy showed lesion of polypoid aspect in the left nasal cavity. He was submitted to biopsy and the anatomopathological exam showed adenoid cystic carcinoma and the patient was forwarded to oncology. Conclusions: The importance of conducting the differential diagnosis between chronic nasosinusal infection and nasosinusal tumors.

Abstract: Adenoid cystic carcinoma constitute around 0.4 to 1.7% of all carcinomas of cervix. It generally presents in elderly age group, however few cases in younger age have also been reported. Majority of cases present in early stage. Though concluding statement regarding the results cannot be made from the cases accumulated from the various reported series, nonetheless this review shows that radiotherapy too is effective in early stage and even in stage I results with radiotherapy appear better than surgery. In advanced stage outcome is invariably poor. In early stage main pattern of failure is distant metastasis. Both local and distant failure are observed in stage III and IV. Though lung is the commonest site of metastases (51%), abdominal cavity and brain are also found to be involved in some cases. Limited experience shows effectiveness of high doses of cisplatin and multiagent chemotherapy. Cases of early stage disease having risk for metastases and local failure should be identified and managed with multimodality treatment using surgery for bulky disease with post-operative radiotherapy and chemotherapy. In advanced stages combination of chemotherapy and radiotherapy is required. Exenterative surgery for central failure has been used effectively. Overall no evidence of disease rate is found to be about 48%, with mean follow-up of 39 months.
Adenoid cystic carcinoma of the parotid metastasizing to liver: case report

Abstract: We report a 60 year old female patient who presented with adenoid cystic carcinoma of the parotid gland. She underwent a total conservative parotidectomy followed by adjuvant radiotherapy. While on follow up, patient developed multiple liver metastases which manifested three years later. Patient lived for another two years before she died of her disease.Although distant metastases of adenoid cystic carcinoma develop frequently, isolated metastasis to liver is unusual. Even after manifestation of distant metastasis, patients can be expected to live for a number of years. Palliative chemotherapy can be considered in symptomatic cases while the usefulness of metastatectomy is controversial.Adenoid cystic carcinoma (ACC) is a rare malignant neoplasm of the salivary gland. Salivary gland neoplasms constitute 3% of cancers of all sites, of which, 10–15% are malignant [1,2]. Though ACC is the most common malignant tumor of the submandibular, sublingual and minor salivary glands, it accounts for only 15% of parotid cancers [3]. They are generally slow growing and spread relentlessly to adjacent structures. Hematogenous spread is more common than lymphatic spread, the common sites of metastasis being the lung, bone and viscera [4,5]. We present a case of multiple liver metastases occurring 3 years after surgery for ACC of the parotid gland. The primary therapy, metastasis and outcome of ACC are discussed.A 60 year old woman presented with a small swelling beneath the right ear lobe of 4 months duration. The swelling measured 2 × 1 cm placed in the superficial part of the parotid and was not fixed. There was no facial nerve palsy or palpable cervical nodes. A fine needle aspiration cytology (FNAC) was carried out which showed the lesion to be ACC [6]. The clinical staging was T1, N0, M0. The patient underwent a total conservative parotidectomy after metastatic work up. Histopathology revealed ACC with cribriform pattern and perineural invasion (Figure 1). 60 Gy adjuvant exter

Abstract: The MitoChip v2.0 resequencing array is an array-based technique allowing for accurate and complete sequencing of the mitochondrial genome. No studies have investigated mitochondrial mutation in salivary gland adenoid cystic carcinomas.
Cystic adenoid carcinoma of sphenoidal sinus

Revista de la Sociedad Otorrinolaringológica de Castilla y León, Cantabria y La Rioja , 2012,
Abstract: Adenoid cystic carcinoma (ACC) is a malignant epithelial tumor of the salivary glands, which usually gives metastases late, but his persistent and aggressive because of its ability to infiltrate surrounding tissue and nerve fibers. ACC of paranasals sinus may spread following the path of the cranial nerves. The close relationship with vital structures prevents complete tumor resection leaving positive margins up to 80 % of patients, mainly at the base of the skull with a high rate of local recurrences and late metastases, aggressive due to its ability to infiltrate surrounding tissue and nerve fibers.
Pulmonary adenoid cystic carcinoma : An unusual presentation
Dixit Ramakant,Nuval Paras
Lung India , 2007,
Abstract: Adenoid cystic carcinoma is a rare but distinctive salivary gland type malignant neoplasm that arises infrequently in the respiratory tract, where it is largely seen in the trachea or large airways. A 29-year-old female who presented with a peripheral lung mass due to pulmonary adenoid cystic carcinoma is reported in view of its unusual location, early age of presentation and lack of such reports in the recent literature. Lung India 2007; 24 : 28-29

Lung India , 2010,
Abstract: We report an extremely rare case of primary adenoid cystic carcinoma (ACC) trachea presenting as midline swelling neck and mimicking thyroid tumor. A 44-year-old female presented with painless midline swelling neck without any respiratory complaints, hoarseness of voice or dysphagia etc. Fine needle aspiration cytology (FNAC) from swelling reveal features of papillary carcinoma thyroid. Subsequently the operative findings, bronchoscopy and histological diagnosis of excised mass, along with review of FNAC, revealed features of ACC of trachea with exra tracheal extension anteriorly into the soft tissue neck, without actual invasion of the thyroid gland. The world literature on extension of an ACC arising in the laryngotracheal complex to thyroid or soft tissue neck and clinical manifestation as a thyroid nodule or mass is reviewed. The cytological differential diagnosis of ACC and CT findings are also briefly discussed.

Sao Paulo Medical Journal , 2007, DOI: 10.1590/S1516-31802007000500010
Abstract: context: adenoid cystic carcinomas are malignant tumors that occur in both the major and the minor salivary glands. a laryngeal location is rare because of the paucity of accessory salivary glands in this area. adenoid cystic carcinomas account for less than 1% of all malignant tumors in the larynx, and only about 120 cases have been reported in the literature. these tumors have a slight female predisposition, and their peak incidence is in the fifth and sixth decades of life. in this article, we describe a case of laryngeal adenoid cystic carcinoma and discuss its clinical characteristics and treatment. case report: we report on a case of laryngeal adenoid cystic carcinoma in a 55 year-old female patient who presented with dyspnea and hoarseness. features of the diagnostic and therapeutic evaluation are described and the clinical management of such cases is outlined. the clinical course, definitive treatment strategy and surgical procedure, and also adjuvant treatment with irradiation are discussed. although the tumor is radiosensitive, it is not radiocurable.
