Gamna-Gandy (GG) bodies are non-infectious, hyphal-like structures associated with siderotic nodules in lymphoid tissue; GG bodies are very rarely reported in veterinary cytologic samples. Cytologically, GG bodies can be misidentified as hyphae or plant material. Seven canine lymphoid tissue aspiration cases that contained GG bodies were investigated for morphologic variability and staining characteristics. Available archived cytology slides containing GG bodies were stained with reagents known to show positive results (Prussian blue, Alizarin red S, Von Kossa) and negative results (Gomori methenamine silver) in histologic samples...

Oncocytic variant of medullary thyroid carcinoma is rare form of thyroid carcinoma that is easily misdiagnosed on fine needle aspiration specimens due to it is low incidence and cytomorphologic overlap with other more common Hurtle cell lesions. A correct initial diagnosis by fine needle aspiration is imperative as the clinical treatment for medullary carcinoma differs significantly from the mimickers. We present a case of this rare variant tumor that on initial fine needle aspiration was described as a Hurthle cell lesion and was subsequently correctly classified on the resection specimen...

BACKGROUND: The newly termed tumor 'noninvasive follicular thyroid neoplasm with papillary-like nuclear features' (NIFTP) acts in an indolent manner and can likely be safely managed with a thyroid lobectomy. Preoperative fine-needle aspiration (FNA) is the cornerstone of surgical planning, but the ability of FNA to distinguish NIFTP from other variants of papillary thyroid carcinoma (PTC) has not been well-evaluated. METHODS: A 9-year retrospective review of the preoperative cytology and surgical pathology of PTC patients who underwent a thyroidectomy at our tertiary referral center...

The literature on Galectin-3 (Gal-3) was systematically reviewed to achieve more robust information on its histologic reliability in identifying thyroid cancers and on the concordance between Gal-3 test in histologic and cytologic samples. A computer search of the PubMed and Scopus databases was conducted by combinations of the terms thyroid and Gal-3. Initially, 545 articles were found and, after their critical review, 52 original papers were finally included. They reported 8172 nodules with histologic evaluation of Gal-3, of which 358 with also preoperative FNAC Gal-3 assessment...

OBJECTIVE: Investigation of thyroid nodules using fine-needle aspiration cytology (FNAC) gives indeterminate results in up to 30% of samples using the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). We present a combined Bethesda-molecular predictor of nodule malignancy to improve the accuracy of the preoperative diagnosis of thyroid nodules. DESIGN: The study sought to detect a molecular signature of thyroid nodule malignancy. METHODS: A molecular test was performed on FNACs from 128 thyroid nodules from prospectively included patients, collected in a tertiary center...

Pseudoangiomatous stromal hyperplasia (PASH) is a breast stromal change, histologically characterized by anastomosing, slit-like spaces lined by slender myofibroblasts and surrounded by dense collagenous stroma. Mass forming cases clinically and radiologically simulate fibroadenoma. A middle aged women presented with unpalpable breast nodule discovered on ultrasound examination. The ultrasound characteristics were typical for fibroadenoma, while fine-needle aspiration cytology was inconclusive. The histological examination of the lumpectomy specimen showed fibroadenoma with peculiar stromal alteration consistent with pseudoangiomatous stromal hyperplasia...

The encapsulated and noninvasive follicular variant of papillary thyroid carcinoma has been recently reclassified as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). These tumors demonstrate indolent behavior. This change in nomenclature will have great clinical impact by avoiding overtreatment of patients with NIFTP lesions who in the past were diagnosed with thyroid carcinoma and typically received completion thyroidectomy followed by radioactive iodine ablation. The pathologic diagnosis of NIFTP requires surgical removal of the thyroid lesion or the lobe harboring it, and thorough sampling of the complete interface between the tumor capsule and the thyroid parenchyma, to exclude foci of invasion...

Thymic adenocarcinoma is extremely rare. Although its histologic features have been occasionally reported, a lack of description of the cytologic features has hampered the prompt and accurate diagnosis of this condition. Herein, we describe the cytologic findings and histology of four aspiration cytology specimens of thymic adenocarcinoma. The specimens were obtained from primary tumors, metastatic lymph nodes, and pericardial effusions. All four specimens showed three-dimensional glandular clusters with a loss of polarity and nuclear overlapping...

Limited literature is available on the use of fine needle aspiration (FNA) for skin tumors. Awareness of cytological features of these lesions is important to prevent misdiagnosis. A 45-year-old male, presented with slowly growing swelling over the thigh since 4 years. FNA from multiple sites yielded highly cellular smears with a dual cell population consisting of cells with small round nucleus scanty cytoplasm and polygonal cells with moderate to abundant cytoplasm. Extracellular basement membrane like material was also noted...

BACKGROUND: Recommendations regarding how many nodules to biopsy with thyroid fine-needle aspiration vary. METHODS: The authors reviewed fine-needle aspiration specimens of 12,763 nodules from 10,506 patients and correlated them with the number of nodules biopsied. RESULTS: Compared with patients in whom only a single nodule was biopsied, patients in whom multiple nodules were biopsied were found to be significantly younger, more likely female, and to have larger tumors, and those tumors were more often papillary (all P<...

Warthin-like mucoepidermoid carcinoma is a recently proposed variant of musoepidermoid carcinoma. Histologically, it is characterized by its close resemblance to Warthin tumor, including dense lymphocytic infiltration, flattened intermediate epithelium resembling squamous metaplasia, and cystic change. Given its histologic similarity to Warthin tumor, confirmatory testing for MAML2 rearrangement is often required for this diagnosis. Here we present the first cytologic reports of two 53-year-old female patients with parotid masses...
