Purpose of Review: Bronchial and bronchiolar abnormalities in interstitial lung diseases (ILDs) are an issue often underestimated. However, new interstitial patterns with bronchiolar involvement are being described and the concept is still evolving. The scope of this review is to introduce a comprehensive approach to airway disorders in the context of ILDs, mainly from a pathologic perspective. Recent Findings: Recent studies have revealed significant inflammatory and structural alterations at the level of small airways in idiopathic interstitial pneumonias, which may participate in the lung-remodeling pathogenetic process. A suggested pathogenetic role of cigarette smoking for lung-remodeling in smoking-related ILDs is further investigated, and unclassified fibrosis as a prominent feature in lung biopsy specimens of smokers has been established. New targeted therapies for lymphangioleiomyomatosis based on molecular and biologic properties of the disease are currently undergoing clinical trials. Combined pharmaceutical and interventional therapeutic regimens are of growing concern for refractory airway lesions in sarcoidosis. The application of volumetric high-resolution computed tomography (HRCT) chest scanning with acquisition of expiratory images provides valuable information about the involvement of small airways in ILDs. Summary: The imaging and pathologic focus on airway abnormalities in ILDs make them an integral part of their pathology with a significant pathogenetic role in interstitial processes and variable contribution to the functional status of patients. © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Objectives: Metastatic tumors in the external auditory canal (EAC) are exceptionally rare. These metastases almost always occur in the latter stages of the disease process. Ten cases of metastatic tumors of the EAC have been reported in the literature. We report the first case of a metastatic bronchogenic adenocarcinoma that presented initially as an EAC mass. Methods: We present a case report and a literature review. Results: Although bronchogenic adenocarcinoma not uncommonly metastasizes to the temporal bone, metastasis to the EAC is extremely rare. We report the case of a 62-year-old woman who presented with a 6-week history of swelling in her right EAC and sudden onset of hearing loss. Physical examination revealed a small, polypoid, friable mass originating from the superior-posterior wall of the right EAC. Incision biopsy was performed, and the histopathologic examination of specimens revealed a moderately to poorly differentiated adenocarcinoma compatible with a bronchogenic origin. Conclusions: A patient with an aural mass presents a diagnostic dilemma. Metastatic tumors in the EAC are extremely rare, but they should be included in the differential diagnosis of a mass in this location. © 2013 Annals Publishing Company. All rights reserved. Source

Background. Hashimoto thyroiditis (HT) is associated with an increased risk of developing papillary thyroid carcinoma (PTC). The relationship between thyroid autoimmunity and cancer remains controversial. The purpose of this study was to investigate whether the preoperative TgAb could be a potential predictor of PTC in patients with thyroid nodules and to assess whether there is an association of preoperative TgAb with lymph node metastases. Methods. This retrospective, nonrandomised study included 854 patients who underwent standard total thyroidectomy. Benign thyroid nodules were diagnosed in 447 patients, and 407 presented with malignant nodules. The examined parameters included the clinical characteristics, preoperative TSH and TgAb levels, and the histopathological characteristics of the tumour. Results. Tumour size >10 mm (p = 0.01), the presence of PTC (p < 0.001), elevated TSH levels (2.64 ± 1.28 μU/ml vs. 2.09 ± 0.98 μU/ml, p = 0.001), HT (p < 0.001), and lymph node metastasis (p = 0.005) were significantly associated with positive TgAb. Additionally, tumour size >10 mm (p < 0.001), preoperative TgAb positivity (p = 0.003), and elevated TSH levels (TSH > 3.4 μU/ml, p = 0.038) were independent risk factors for PTC based on the multivariate logistic regression analysis. Conclusions. This study showed that TgAb positivity was an independent risk factor for PTC. A positive correlation between TgAb and PTC in patients with indeterminate nodules was existed. Additionally, a positive correlation existed between TgAb and lymph node metastases in patients with PTC. Prospective studies with a larger number of patients and long-term follow-up are needed clarify the potential role of positive serum TgAb in the prediction of PTC. © 2014 Society of Surgical Oncology.

Metastatic tumors to the palatine tonsils are extremely rare, with nearly 100 cases reported. Only 3 cases of Merkel cell carcinoma of the skin metastasizing to the palatine tonsil have been reported. We present the interesting case of a 61-year-old man with an enlargement of the left palatine tonsil that caused a moderate narrowing of the oropharynx. Three years previously he had been treated for Merkel cell carcinoma (MCC) on skin of his left shoulder. A tonsillectomy followed by palatoplasty was performed. Immunohistochemical staining demonstrated a pronounced reaction for cytokeratin 20, chromogranin, and CD56 histodiagnostic markers. Immunohistochemical studies are useful diagnostic tools in the establishment of the diagnosis of MCC. Treatment includes wide local surgical excision of the tumor, radiotherapy, and chemotherapy. Considering the aggressiveness of MCC, an early diagnosis is critical to enable the choice of adequate therapy at an early stage. © 2013 American Association of Oral and Maxillofacial Surgeons.

Symmetrical lipomatosis of the tongue is an extremely rare condition. To date, only eight cases have been reported in the literature. We present an extremely rare case of intramuscular lipomatosis of the tongue in a 67-year-old male. The present case is unique because of its infiltrating nature and the extension of the lesion. Glossectomy was performed to reduce the size of the tongue and for diagnosis. The literature is reviewed and clinical characteristics, pathology, and surgical treatment are discussed.
