BACKGROUND: In recent years, there have been increasing indications for percutaneous renal biopsy. Fine-needle aspiration (FNA), with or without core needle biopsy (CB), has been used increasingly in the management of renal tumors at the study institution. METHODS: A computerized search of laboratory records was conducted to retrieve FNA cases of renal masses as well as the correlating CB and/or nephrectomy specimens. The cases spanned a period of 10 years (2006-2015)...

Sclerosing polycystic adenosis (SPA) is a rare benign neoplasm of the salivary gland which resembles the fibrocystic disease of the breast clinically as well as morphologically. This entity has varied morphological presentation on fine needle aspiration. Only a few case reports and occasional case series are found in the literature describing its cytology. Here we are presenting a case of SPA in the parotid gland in a 13-year-old male patient who presented with a slow growing infra-auricular mass since one year without any other symptoms...

The thyroid is a rare site of clinically detectable tumor metastases; even though the gland is a highly vascularized structure, the frequency of metastases in the routine practice is less than 0.2% of all thyroid malignancies. The purpose of our meta-analysis is to evaluate the frequency of metastatic diffusion from other primary tumors to the thyroid gland and to suggest the best possible treatment through an evidence-based study. Relevant studies were identified by searching the following databases: PubMed, Scopus, and Web of Science...

Background. High-resolution ultrasonography and the ability to perform fine-needle aspiration biopsy even for nodules smaller than three millimeters have considerably increased the detection rate of thyroid micropapillary carcinoma (TMPC). Despite favorable prognosis, the prevalence of cervical lymph node metastases in patients with TMPC is approximately 30%. Aim. In this study, we aimed to determine the central lymph node metastasis rate and its relation to the characteristics of the tumor. Methods. One hundred nine patients who underwent surgery due to TMPC between December 2009 and January 2014 were analyzed retrospectively...

Preoperative differential diagnosis of gastric submucosal tumors has generally been difficult because they are covered with normal mucosa. However, recent advances in endoscopic ultrasound (EUS)-guided sampling of submucosal gastrointestinal lesions have made it possible to achieve preoperative differential diagnosis of gastric submucosal tumors. A 76-year-old woman was referred to our hospital with a gastric submucosal tumor. The tumor was observed in the antrum of the stomach. It was preoperatively diagnosed as a schwannoma after immunohistochemical evaluation of a biopsy specimen, obtained using endoscopic ultrasound-guided fine needle aspiration...

Actinomycosis is a slowly progressive, chronic infectious disease. It is caused by the genus Actinomyces, which are gram-positive anaerobic bacteria. It presents as a mass-like lesion, composed of bacterial nidus and characteristic granulomatous inflammatory fibrosis. As such, it has frequently been mistaken for a malignancy. Surgical resection is a common procedure in these patients prior to a definite diagnosis. Although actinomycosis can occur in a variety of regions, including oral-cervicofacial, thoracic, and abdominopelvic cavities, the involvement of the pancreas is very rare...

BACKGROUND: The metastases of a primary lung cancer over the thyroid gland are extremely rare. We report on an unusual presentation of thyroid metastasis of lung cancer in order to improve the management of similar cases. CASE PRESENTATION: Three years ago, a Moroccan male 59-year-old was admitted for dyspnea, dry cough, and chest pain. He had smoked about 30 cigarette packs a year. Clinical examination revealed a right thyroid nodule. Chest and neck computed tomography (CT) scan showed a proximal left tumor in contact with the pulmonary artery and revealed a suspected nodule in the right lobe of the thyroid with homolateral neck node...

BACKGROUND: The reported malignancy rates of thyroid nodules that appear suspicious on ultrasound (US) but yield benign fine-needle aspiration (FNA) cytology results range from 13.6% to 56.6%. However, the malignancy risk of nodules that are discordant on US and core-needle biopsy (CNB) pathological findings has not been evaluated. This study evaluated the malignancy risk associated with thyroid nodules that are suspicious on US but yield benign CNB results. METHODS: Between July 2008 and November 2011, 1309 patients with 1313 thyroid nodules underwent US-guided CNB...

OBJECTIVE: To investigate the clinical significance of cell blocks obtained by ultrasound-guided fine needle aspiration in diagnosing parotid gland masses. METHODS: Cell blocks were made in 285 parotid gland masses by ultrasound-guided fine needle aspiration. Diagnosis was conducted using the cell blocks. Non-tumor masses were subjected to conservative treatment, and cysts and tumors were treated with surgery. The cell block sections from masses with the diagnosis of adenoid cystic carcinoma (ACC) and pleomorphic adenoma (PA) were applied to the detection of immunocytochemical staining for the stem cell factor receptor CD117...

Sclerosing mediastinitis (SM) is an aggressive fibroproliferative process in the mediastinum that may lead to encasement of mediastinal structures within a dense fibrotic mass. This disease may cause significant clinical complications, morbidity, and even mortality. The etiology and pathogenesis of SM is unclear and in more than one third of cases remains idiopathic. Among the known causes of SM, granulomatous infection is the commonest. Association of SM with radiation therapy has been rarely reported. Herein, we are reporting a case of postradiation sclerosing mediastinitis diagnosed in fine needle aspiration (FNA) specimen...

Myoepitheliomas of soft tissue are rare tumors with variable morphologic, immunohistochemical and molecular profiles and therefore are diagnostically challenging for pathologists. We report a case in a 60-year-old male with a painless slowly growing 3cm mass on left medial forefoot. Core biopsy of the mass showed a neoplastic proliferation of plasmacytoid tumor cells, consistent with myoepithelioma of soft tissue. Immunohistochemical stains demonstrated positivity of the tumor cells for cytokeratin AE1/AE3, CK18, S-100 protein and myosin heavy chain (SMMS-1), supporting the diagnosis...

BACKGROUND: Tenosynovial giant cell tumor (TSGCT), also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis, is the most common benign tumor of the tendon and synovium. The intra-articular diffuse type can present as a large infiltrative mass involving adjacent soft tissue and sometimes causes secondary destruction of bone, which leads to radiographic and clinical concern for malignancy. The tumor may also be purely extra-articular. CASE: Here, we report the fine needle aspiration cytology findings of 2 cases of diffuse-type TSGCT with large mononuclear cells with eccentric nuclei, finely granular cytoplasm, and a peripheral well-defined cytoplasmic rim of hemosiderin ("ladybird cells")...

Malignant neoplasms frequently cause vertebral metastases. Traditionally, either image-guided percutaneous biopsy or open biopsy has been performed for sampling specimens for the definitive diagnosis. We herein report a case with suspected multiple metastases but unknown primary, who underwent endobronchial ultrasound-guided transbronchial needle aspiration for mediastinal lymph nodes with negative results by rapid onsite cytologic evaluation, followed by the transesophageal approach with the ultrasound bronchoscope for the vertebral body lesion at the same setting that provided a definitive diagnosis of metastatic hepatocellular carcinoma...

Melanoma is the second most common non-hematopoietic malignancy after carcinomas to metastasize to the breast and often appears as a well-circumscribed, dense nodule on imaging. Although metastatic lesions presenting as bilateral cysts have been reported, this presentation is not common and may mimic benign breast cysts. We present a challenging case of metastatic melanoma presenting as bilateral breast cysts with spindled cytomorphology in a patient with a history of mammary carcinoma. Discordance between the spindled cytomorphology and the morphology of the core biopsy, which was similar to the patient's primary breast cancer, allowed for entertainment of other tumors and disease processes...

REVIEW
Nonthalee Pausawasdi, Thawee Ratanachu-Ek
Incidental pancreatic cysts have been gradually more recognized in clinical practice due to an increased use of transabdominal ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI). These lesions consist of inflammatory cysts (pseudocysts) and pancreatic cystic neoplasms (PCNs) which have been classified as benign, pre-malignant and malignant. The diagnosis and management strategy of incidentally discovered pancreatic cysts can be challenging as the majority of them are PCNs and CT or MRI alone may not be sufficient to provide an accurate diagnosis...

BACKGROUND: Thyroid incidentaloma is defined as an unsuspected thyroid lesion found on imaging study or while performing a surgery non-related to the thyroid gland. Most recent scientific literature tends to demonstrate a detection rate of 0.1-4.3% for incidental findings of thyroid focal uptake identified by (18)F-fluorodeoxyglugose Positron Emission Tomography with computed tomography ((18)FDG-PET/CT) initially prescribed for nonthyroid disease. From 10.3 to 80.0% of patients who underwent further evaluation are diagnosed with malignant lesions...
