Primary adenoid cystic carcinoma of the liver: A case report

<p><span>Adenoid cystic carcinoma (ACC) is primarily found in the salivary glands and rarely at other organs but never reported as liver primary. This is a very rare case of primary ACC of the liver which was not resectable and managed with chemotherapy and targeted therapy. The patient progressed on imatinib (c-kit positive) while responded to chemotherapy and gefitinib (epidermal growth factor receptor mutation absent).</span></p>

Primary adenoid cystic carcinoma in the peripheral lung: a cytological, histopathological and immunohistochemical report of two cases

Primary adenoid cystic carcinoma (ACC) of the peripheral lung is a rare entity. Here we report two cases of primary ACC. Case 1 is an 84-year-old male with a past-medical history of cecal cancer presented with a 10 mm left upper lung nodule. Case 2 is a 40-year-old female who presented with 30 mm right upper lobe. Intraoperative (Case 1) and pre-operative (Case 2) histopathologic and cytologic diagnoses were consistent with a primary peripheral lung ACC. An upper lobectomy±mediastinal lymph node dissection was performed and immunohistochemical staining with thyroid transcription factor (TTF)-1, c-KIT and MYB on the excision specimen confirmed our diagnosis.

Primary adenoid cystic carcinoma of the tracheobronchial tree: A decade-long experience at a health centre in Mexico

Background:Mexico's National Institute of Respiratory Diseases (NIRD) is a third-level national reference center. Primary adenoid cystic carcinoma (PACC) is an uncommon neoplastic disorder; hence improvements in the description of this disease are needed.Materials and Methods:This is a retrospective clinical study based on all consecutive patients with pathological diagnoses of PACC seen at the NIRD between January 1, 2000 and December 31, 2009.Results:We identified 9 cases of PACC (67% female) out of a total of 2,634 patients with lung cancer seen during the period analyzed. The mean age of those 9 patients was 41 years (IQR 36-57), and the frequency of PACC at our center was 0.3%. It is important to note that 67% of those patients had a history of smoking and that 6 of the 9 had the antecedent of previous exposure to biomass fuel smoke. Baseline arterial blood gas analyses revealed a median of 61 mmHg for pO2 and 28.5 mmHg for pCO2. Median FVC was 78%, while FEV1 was 77% with an FEV1 /FVC ratio of 78. Death occurred in 56% of cases, and the median survival time was 17 months (IQR 6-26) after the initial diagnosis.Conclusions:The frequency of tracheobronchial PACC among patients with lung cancer was similar to that previously reported (0.3%). According to our results, lung function has no specific phenotype in this disease; however, some abnormalities could be related to potential risk factors such as tobacco use and exposure to biomass fuel smoke.
