To study the correlation of ultrasonographic signs of small breast cancer (maximum diameter ≤2.0 cm) with axillary lymph node metastasis, pre-operative ultrasonographic images of 153 small breast malignant neoplasms in 143 breast cancer patients were analyzed according to their pathologic features. Of the small breast tumors included, 47 showed axillary lymph node metastasis. Diagnosis of all patients was obtained with radical axillary surgery or a sentinel lymph node biopsy procedure. Ultrasonographic signs included irregular shape, microlobulated contour, spiculation, microcalcification, posterior echo attenuation, blood-flow grade, perforating vessels, changes in fascia or cooper's ligament and maximum cortical thickness of lymph nodes...

Partially cystic thyroid nodules (PCTNs) are common on ultrasound (US). However, there are insufficient data on the prevalence of thyroid carcinoma among such nodules. The purpose of this study was thus to evaluate the prevalence and differentiation of partially cystic thyroid cancers in US-guided fine needle aspiration (FNA).A total of 1342 consecutive patients with 1360 thyroid nodules underwent prospective US diagnosis and FNA biopsy. In total, 281 nodules (20.7%) were partially cystic lesions. The nodules were prospectively analyzed based on US features (ie, solid portion positions, shapes, margins, and microcalcifications) and US diagnosis (benign, suspicious, or malignant)...

Ultrasonography is pivotal in triage thyroid biopsy in the era after the identification of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). This pictorial essay illustrates the pathologic basis of the sonographic features that distinguish NIFTP from thyroid cancers. In this study, we present the correlations of ultrasonography to ×1 histopathology to assess shape and margin characteristics. Markedly hypoechoic nodules correlate to microfollicular/solid nodules, while isoechoic/hyperechoic thyroid nodules correlate to normofollicular/macrofollicular nodules...

PURPOSE: Microcalcifications are a common finding in mammography and usually require invasive procedures to diagnose or exclude malignancy. As many microcalcifications are due to benign lesions, we wanted to assess whether breast MRI as an additional diagnostic tool may be used to distinguish benign from malignant in this setting. MATERIALS AND METHODS: Eligible for this retrospective, IRB-approved observational study were 858 consecutive patients (mean age 54±11years) undergoing stereotactically-guided biopsies of suspicious mammographic microcalcifications during three year at our institution...

The aim of this study was to evaluate the possible development of histological abnormalities such as fibrosis and microcalcifications after sperm retrieval in a ram model. Fourteen testicles in nine rams were exposed to open biopsy, multiple TESAs, or TESE, and the remaining four testicles were left unoperated on as controls. Three months after sperm retrieval, the testicles were removed, fixed, and cut into 1/2 cm thick slices and systematically put onto a glass plate exposing macroscopic abnormalities. Tissue from abnormal areas was cut into 3 μm sections and stained for histological evaluation...

Tuberous sclerosis complex (tsc), a phacomatosis, is a rare genetic disease (autosomal dominant; incidence: 1 in 6,800-17,300) associated with mutations in the TSC1 and TSC2 genes, 70% of which are sporadic. The disease causes benign tumours in the brain, kidneys, heart, lungs, skin, and eyes; thyroid lesions are extremely rare. A 13-year-old euthyroid boy with a hereditary form of tsc (del 4730G in TSC2, also seen in 2 sisters and the father) was admitted to hospital with a thyroid nodule. Physical examination revealed a nodular left lobe with increased consistency...

BACKGROUND AND PURPOSE: Small echogenic foci within pediatric thyroid nodules are commonly seen by ultrasound and are one of the features used to determine the level of suspicion for malignancy. These are sometimes termed "microcalcifications," but their relation with malignancy is controversial due to the lack of standard terminology. Our aim was to evaluate sonographic patterns of echogenic foci in malignant pediatric thyroid nodules and describe the distribution of corresponding psammoma bodies and other histopathologic findings in thyroidectomy specimens...

Xiaoyan Cui, Shi Wei
Ductal or lobular carcinoma in situ (DCIS/LCIS) can rarely arise from sclerosing adenosis (SA). The combination of cytologically malignant cells and the infiltrative growth pattern may make it challenging to distinguish it from an invasive carcinoma. The authors reviewed 50 consecutive cases of CIS involving SA to seek the salient histologic characteristics in order to prevent overdiagnosis. The features commonly seen with CIS were the lobular configuration at low magnification (94%), uninvolved SA in neighboring tissue (84%), at least focally identifiable myoepithelial cells on H&E-stained sections (76%), separate foci of unequivocal CIS (58%), associated microcalcifications (54%), and hyaline basement membrane surrounding tumor cell nests (48%)...

PURPOSE: The 11-gauge (11G) stereotactic vacuum-assisted breast biopsy (VABB) showed a better profile than 14G-VABB in terms of feasibility, safety, microcalcification sampling, and accuracy. Underestimation rates were significantly lower with 11G-VABB than with 14G-VABB. Thus, the introduction of an even larger needle at the VABB procedure could reduce this rate further. The purpose of this study was to compare the overall performance of stereotactic VABB with 8G and 11G needles. MATERIALS AND METHODS: Four hundred and three VABBs performed between July 2012 and February 2015 at the Breast Diagnostic Unit of Careggi Hospital in Florence were retrospectively analyzed; 197 were performed with 11G-VABB and 206 with 8G-VABB...

BACKGROUND: The incidence of thyroid cancer is increasing worldwide, and there is an emerging need to develop accurate tools for diagnosis. Fine needle aspiration biopsy has greatly improved evaluation of thyroid nodules, but challenges with indeterminate lesions remain in up to 25% of biopsies. Novel tissue biomarkers may assist in improved nodule characterization. Microcalcifications occurring in thyroid cancers suggest proteins involved in bone formation may play a role in thyroid carcinogenesis...
