BACKGROUND: Intrathoracic tuberculous (TB) lymphadenitis is a diagnostic challenge to the clinician. Although endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can obtain a sample from the affected lymph node, the diagnosis of TB lymphadenitis by cytopathology remains inaccurate. OBJECTIVE: To evaluate the efficacy of EBUS-TBNA rinse fluid TB polymerase chain reaction (PCR) assay for the diagnosis of intrathoracic TB lymphadenitis. METHODS: A retrospective study was conducted on 102 patients who underwent EBUS-TBNA for diagnostic evaluation of intrathoracic lymphadenopathy...

Primary pulmonary neoplasms of the Ewing family of tumors (EFT) are extremely rare and usually occur in adolescents or young adults. Only about 40 cases of pulmonary EFT have been reported in English literature, and no cytological studies have been documented. In this report, we describe the cytopathological findings of a primary pulmonary EFT in an elderly patient. A 70-year-old man sought care because of a progressing cough and dyspnea. Chest computed tomography revealed a circumscribed mass of 6 cm in the left upper lobe...

The Bethesda System for Reporting Thyroid Cytology (TBSRTC) was proposed in 2007 at the National Cancer Institute Thyroid Fine Needle Aspiration State of the Art and Science Conference held in Bethesda, Maryland. The aim was to address the inconsistent and sometimes confusing reporting terminologies used for thyroid FNA throughout the world. The TBSRTC consists of 6 diagnostic categories, each associated with an implied risk of malignancy that translates directly into a clinical management algorithm. Since the publication of the TBSRTC cytology Atlas in January 2010, considerable experience has been gained regarding its application in cytology practice, clinical impact, and limitations...

INTRODUCTION: The increasing use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology to examine pancreatic neoplasms has led to an increase in the diagnosis of metastases to the pancreas. Renal cell carcinoma (RCC) is the most common metastasis to the pancreas. Our study examines 33 cases of metastatic RCC to the pancreas sampled by EUS-FNA from four large tertiary care hospitals. MATERIALS AND METHODS: We searched the cytopathology database for RCC metastatic to the pancreas diagnosed by EUS-FNA from January 2005 to January 2015...

A 5.5-year-old, intact male Rottweiler dog was admitted with a history of multifocal nodular tongue lesions which progressively deteriorated during the previous year. Physical examination revealed several reddish nodules with central depression on the surface of the tongue in an otherwise healthy dog. Clinicopathologic abnormalities included eosinophilia and hyperproteinemia. Lingual nodule cytopathology, histopathology, and immunohistochemistry revealed Leishmania spp. amastigotes and a severe granulomatous glossitis...

Cervical cancer, the second most common cancer affecting women in Northern Brazil, is strongly associated with human papillomavirus (HPV) infection. Diseases affecting the immune state of a patient, including autoimmune diseases like systemic lupus erythematosus (SLE), can lead to persistent HPV infection and cancer. We evaluated cervical HPV prevalence and the associated risk factors in 70 women with SLE in the city of Belém, located in Brazilian Amazon. HPV DNA was detected by PCR using primers MY9 and MY11...

BACKGROUND & OBJECTIVES: The two key aspects associated with the microsatellite instability (MSI) as genetic phenomenon in colorectal cancer (CRC) are better survival prognosis, and the varying response to 5-fluorouracil (5-FU)-based chemotherapy. This study was undertaken to measure the survival of surgically treated patients with stages II and III CRC based on the MSI status, the postoperative 5-FU treatment as well as clinical and histological data. METHODS: A total of 125 consecutive patients with stages II and III (American Joint Committee on Cancer, AJCC staging) primary CRCs, were followed prospectively for a median time of 31 months (January 2006 to December 2009)...

Urine cytology and qPCR in blood and urine are commonly used to screen renal transplant recipients for polyomavirus-associated nephropathy (PVAN). Few studies, however, have directly compared these two diagnostic tests, in terms of their performance to predict PVAN. This was a systematic review in which adult (≥ 18 years old) renal transplant recipients were studied. A structured Pubmed search was used to identify studies comparing urine cytology and/or qPCR in urine and plasma samples for detecting PVAN with renal biopsy as the gold standard for diagnosis...

In this study, antiviral effect of porphyrin was investigated. Cooper strain of Bovine Herpes Virus type 1(BoHV-1) and Kos strain of Herpes Simplex Virus type-1 (HSV-1) were used to determine the potential of porphyrins to inhibit infection in vitro (with morphological and cytopathological criteria). Apoptotic and necrotic changes were determined by using DAPI and propidium staining. The non-cytotoxic dose of porphyrin (NCD-p) was initially calculated as 312.50µg/mL on MDBK and Vero cells. The apoptotic cell (APC) count was found 10% with BoHV-1 while it was 5...

BACKGROUND: Papanicolaou Society of Cytopathology guidelines place low- and intermediate-grade pancreatic endocrine tumors into the "neoplastic, other" category whereas high-grade pancreatic endocrine tumors are placed in the "malignant" category. No attempt was made to stratify pancreatic endocrine tumors in the "neoplastic, other" category by likelihood for metastases. Histologically, pancreatic endocrine tumors are divided into well, intermediate, and poorly differentiated examples based on mitotic count and Ki-67 proliferation index (PI)...

Herpes zoster or shingles is reactivation of the varicella zoster virus that had entered the cutaneous nerve endings during an earlier episode of chicken pox traveled to the dorsal root ganglia and remained in a latent form. This condition is characterized by occurrence of multiple, painful, unilateral vesicles and ulceration which shows a typical single dermatome involvement. In this case report, we present a patient with herpes zoster involving the mandibular division of the trigeminal nerve, with unilateral vesicles over the right side of lower third of face along the trigeminal nerve tract, with intraoral involvement of buccal mucosa, labial mucosa and the tongue of the same side...

Metagenomic surveys and data from next generation sequencing revealed that mixed infections among plant viruses are probably a rule rather than an exception in natural pathosystems. The documented cases may range from synergism to antagonism, which may depend from the spatiotemporal order of arrival of the viruses on the host and upon the host itself. In synergistic interactions, the measurable differences in replication, phenotypic and cytopathological changes, cellular tropism, within host movement, and transmission rate of one of the two viruses or both are increased...

OBJECTIVES: Although updated HER2 testing guidelines have been improved by a collaboration between the American Society of Clinical Oncology (ASCO) and the College of American Pathologists (CAP) in 2013, HER2 evaluation is still problematic because of issues involving CEP17 polysomy, heterogeneity, and HER2 score 2+ cases. The aim of this retrospective study was to evaluate the relationship between HER2 gene heterogeneity, or so called CEP17 polysomy, using breast carcinoma cells sampled by scraping and the IHC score graded by automated image analysis using whole slide image...
