Intravascular papillary endothelial hyperplasia, previously known as Masson's tumor, is a relatively uncommon reactive endothelial proliferation that occurs most commonly in the vessels of the head, neck, and extremities. We report a case of intravascular papillary endothelial hyperplasia in the neck in a 40-year-old female that was misdiagnosed as papillary adenocarcinoma on fine needle aspira...

Introduction: Fine needle aspiration cytology (FNAC) is the routine, minimal invasive technique, and well-established baseline investigation used to diagnose the nodular thyroid lesion. The main disadvantages were an inadequate specimen or the specimen obtained was blood. To avoid these problems, a new method called as fine needle non-aspiration cytology is performed nowadays instead of FNAC. A...

Sonography is the modality of choice for imaging cervical lymph nodes in patients with papillary thyroid cancer, both before surgery and for postoperative surveillance. Sonography is also an invaluable tool to guide fine-needle aspiration of abnormal nodes. Microcalcifications, cystic changes, abnormal morphology, and disordered vascularity are features of metastatic nodal involvement with papi...

A case of primary amyloid tumour of the breast is reported with a brief review of the literature. The tumour was mammographically suspicious of carcinoma. Fine needle aspiration cytology yielded clumps of amorphous material surrounded by giant cells and lymphocytes. Subsequent histology showed nodular amyloid associated with osseous metaplasia and giant cell reaction. There are 13 cases of amyl...

Fine needle aspiration of thyroid has been used for years in a multidisciplinary approach, to diagnose different entities, in preventing over or under treatment of thyroid nodules. The widespread use of this methodology can be confirmed if "thyroid fine needle aspiration" is searched on PubMed, which results in over 5000 papers. In this manuscript, we aimed to focus on pitfalls in the evaluatio...

BACKGROUND Acinar cell carcinoma of the pancreas is a rare neoplasm. Although this tumor has been well characterized histologically, the morphological patterns in Fine Needle Aspiration Cytology have not been well defined. Unlike ductal adenocarcinomas, endocrine tumors, and solid pseudopapillary tumors of the pancreas with their characteristic FNA cytological features, acinar cell carcinomas p...

INTRODUCTION Endoscopic biopsy techniques are useful in the diagnosis of sarcoidosis. There is a need for randomized trials to establish where these procedures fit in the diagnosis of sarcoidosis. OBJECTIVES The aim of the study was to compare the diagnostic yield of conventional transbronchial needle aspiration (TBNA) with endobronchial ultrasound-guided TBNA (EBUS-TBNA) and endoscopic ultra...

PURPOSE The purpose of this study was the clinical evaluation of ultrasound-guided biopsy in comparison with ultrasound-guided fine-needle aspiration biopsy of identical, non-palpable breast lesions. MATERIALS AND METHODS From August 1997 until July 1998, 73 ultrasound-guided biopsies were performed in 66 patients with non-palpable lesions of the breast. In 18 patients (age 33-77 years) with ...

BACKGROUND Mammary sclerosing lobular hyperplasia is an uncommon benign lesion of adolescent and young women. Fine-needle aspiration cytology of mammary sclerosing lobular hyperplasia is said to show characteristic features that include an absence of stromal fragments. CASE PRESENTATION In this article, we describe a case of sclerosing lobular hyperplasia that occurred in the right breast of ...

OBJECTIVES The exact preoperative diagnosis of parotid gland masses requires highly specific and sensitive diagnostic techniques. The specificity, sensitivity and accuracy of ultrasonography guided fine needle aspiration biopsy of parotid gland masses were assessed. PATIENTS AND METHODS There were 46 female and 36 male patients. The mean age was 39 years (range 18 to 74 years). Ultrasonograph...
