Prostatic stromal sarcomas (PSS) are rare solid organ mesenchymal sarcomas. PSS may pose difficult diagnostic challenges on fine needle aspiration biopsy. We report a 48-year-old man diagnosed with metastatic high grade prostatic stromal sarcoma by a CT-scan guided fine needle aspiration (FNA) biopsy of a right lower lung lobe nodule. We reviewed the literature on the epidemiologic, cyto-histol...

Introduction: The preoperative diagnostic evaluation of the parotid lesion is a valuable aid in planning the operation and the approach to intervention. Among different diagnostic tools, Fine Needle Aspiration has a key role. However, the exact efficacy of this technique in our center had not been thoroughly investigated. Materials and Methods: Between January 2000 and June 2007 a subset of ...

Background: Fine-Needle Aspiration Cytology (FNAC) is used for diagnosis of intraocular, orbital and eyelid lesions. In this study we evaluated the outcome and the accuracy of using this technique in diagnosis of benign or malignant behavior of lesions. Methods: FNAC was performed on 26 specimens obtained from 25 patients with intraocular, orbital and eyelid tumors and the results were compared...

Pilomatricoma is a benign skin adnexal tumour usually seen in the head and neck region of children and young adults. It is underrecognized on cytology, resulting in the overdiagnosis of malignancy. We bring forth a case report of a slow growing nodular swelling in a 10-year-old female child, which was misdiagnosed on Fine Needle Aspiration Cytology (FNAC) as a malignant neoplasm and found to be...

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...

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...

The description of precise intrabronchial positions for the sampling of mediastinal-hilar lymph nodes is critical to successfully perform conventional transbronchial needle aspiration. Previously published maps of mediastinal-hilar lymph nodes were primarily drawn based on experts' experience. We generated a virtual map of the most frequently sampled intrathoracic lymph nodes from an intrabronc...

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 ...
