Segmentation of cells/nuclei is a challenging problem in 2-D histological and cytological images. Although a large number of algorithms have been proposed, newer efforts continue to be devoted to investigate robust models that could have high level of adaptability with regard to considerable amount of image variability. In this paper, we propose a(More)
CONTEXT Fine-needle aspiration has become an accepted and cost-effective procedure for rapid diagnosis of thyroid lesions. The routine use of fine-needle aspiration has reduced the rate of unnecessary surgery for thyroid nodules. OBJECTIVES To determine the accuracy of fine-needle aspiration biopsy diagnosis and to discuss the possible pitfalls. Design,(More)
CONTEXT Fine-needle aspiration (FNA) is recommended as an initial screening tool for the diagnosis of thyroid nodules. Approximately 10% of thyroid FNA diagnoses are "suspicious for neoplasm," warranting surgical resection. OBJECTIVES To examine the role of a patient's age, sex, size of nodule, and morphologic features as possible predictors of malignancy(More)
CONTEXT The current study compares data from our hospital system before and after the 2008 implementation of the Bethesda System for Reporting Thyroid Cytology (BSRTC). OBJECTIVE To show the effects the BSRTC has had on the reporting rates and outcomes for thyroid lesions. DESIGN A search for thyroid fine-needle aspiration biopsies (FNABs) was performed(More)
We present 2 unusual cases of long-standing, extensive reactive lymphadenopathy secondary to Actinomyces infection, 1 of which was also accompanied by Actinobacillus actinomycetemcomitans-Actinomyces complex infection. To our knowledge, histologic features of lymph node involvement by these organisms have not been previously reported in the literature. One(More)
We report the case of a 41-year-old black man with acquired immunodeficiency syndrome who developed a severe chronic anemia due to parvovirus infection. Bone marrow biopsy revealed erythroid aplasia. The infectious nature of the anemia was not recognized, and the patient was treated with erythropoietin. The patient's reticulocyte response was inadequate,(More)
OBJECTIVE To illustrate some of the uncommon cytologic findings of gynecomastia, such as apocrine metaplasia, cellular atypia and foamy macrophages, that can be misinterpreted as evidence of malignancy. STUDY DESIGN The clinical data and fine needle aspiration (FNA) cytologic material from 100 men with the diagnosis of gynecomastia were retrospectively(More)
Lactobacilli are gram positive rod-shaped or filamentous bacteria that are a rare cause of endocarditis. We review the literature of less than 50 reported cases, and present a case of a 43-year-old male with a protracted, one-year history consistent with endocarditus. The pathologic findings in the heart at autopsy indicate a long, chronic course of(More)
Blastomycosis is an uncommon disease caused by the dimorphic fungus Blastomyces dermatitidis. It can manifest as chronic pulmonary symptoms or disseminated disease. Only three previous cases of blastomycosis involving the thyroid have been reported, of which two were diagnosed by fine-needle aspiration. We present a case of disseminated blastomycosis(More)
Pulmonary papillary adenomas are very rare benign neoplasms, with approximately 24 cases reported in the English literature. They typically do not contain any more than an occasional focal area of sclerosis. Indeed, sclerotic interstitium within a sclerosing hemangioma has been reported to be a criterion used to distinguish it from pulmonary papillary(More)
