Primary cutaneous apocrine carcinomas are uncommon malignant neoplasms that can be difficult, if not impossible, to distinguish histologically from metastatic breast carcinomas. We present the case of a 71-year-old man with a 5-year history of extensive ulcerated plaques on the posterior neck and posterior scalp. Biopsy revealed a poorly differentiated infiltrating adenocarcinoma consistent with either primary cutaneous apocrine carcinoma or occult metastatic breast carcinoma. Immunohistochemical analysis demonstrated positive staining for cytokeratin (CK) 7, estrogen receptor, and progesterone receptor, and negative staining for p63, podoplanin, CK20, and thyroid transcription factor 1...

INTRODUCTION: Increasing emphasis is being placed on appropriateness of care and avoidance of over- and under-treatment. Indeterminate thyroid nodules (ITN), present a particular risk for this problem because cancer found via diagnostic lobectomy (DL) often requires a completion thyroidectomy (CT). However, initial total thyroidectomy (TT) for benign ITN results in lifelong thyroid hormone replacement. We sought to measure the accuracy and factors associated with the extent of initial thyroidectomy for ITN...

BACKGROUND: Encapsulated non-invasive follicular variant papillary thyroid cancer (ENIFVPTC) has recently been re-termed noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). This designation specifically omits the word "cancer" to encourage conservative management since patients with NIFTP tumors have been shown to derive no benefit from completion thyroidectomy or adjuvant radioactive iodine (RAI) therapy. METHODS: IRB approved retrospective study of consecutive cases of tumors from 2007 to 2015 that met pathologic criteria for NIFTP...

BACKGROUND/AIM: Microcalcifications are generally accepted as highly specific for thyroid malignancy, especially for papillary thyroid carcinoma (PTC). The aim of this study was to determine the significance of microcalcification within nodules that were classified as being of “indeterminate cytology” (IC) according to fine-needle aspiration biopsy. MATERIALS AND METHODS: Patients who underwent thyroidectomy between January 2010 and 2013 were included in the study...

Radioiodine has served an important role in the diagnostic workup and treatment of patients with differentiated thyroid cancer for more than 6 decades. The interpretation of radioiodine scintigraphic studies should be performed in conjunction with a comprehensive history, histopathologic correlation, and pertinent laboratory values, as well as correlation with available anatomic images and the findings from physical examination. A thorough understanding of the physiology and biodistribution of radioiodine is critical when interpreting radioiodine scintigraphic studies to avoid misinterpretation of physiologic and nonthyroid pathologic variants as thyroid cancer metastases...

BACKGROUND: Major differences with respect to the diagnostic performance of a "ruling in" approach in the pre-surgical diagnosis of indeterminate thyroid fine needle aspirations (FNAs) have been reported. Therefore, the aim of this prospective multicenter study was to investigate the specific diagnostic impact of mutation testing using a 7-gene-panel in a routine primary referral setting analyzing FNAs from endocrinology and nuclear medicine practices in Germany. METHODS: RNA and DNA was extracted from 564 routine air-dried FNA smears obtained from 64 physicians and cytologically graded by one experienced cytopathologist...

INTRODUCTION: A rapidly enlarging mass of the anterior compartment of the neck with compressive symptoms may represent, among other diagnosis, a neoplasm of the thyroid gland. PRESENTATION OF CASE: We describe the case of a 59-year-old woman referred to the endocrine surgical unit because of compressive cervical symptoms for 3 months. The cervical ultrasound revealed a sub-sternal goiter with heterogeneous echo structure and the fine-needle aspirating cytology was inconclusive...

PURPOSE: In contrast to other thyroid carcinomas it is difficult to establish a correct preoperative diagnosis for oxyphile carcinoma of the thyroid. In this study we looked for predictive malignancy factors in order to enable surgeons to choose operative treatment and to perform an adequate operation for each patient with an oxyphile neoplasm of the thyroid. METHODS: In this retrospective study we have analyzed the medical files of all patients with oxyphile tumors of the thyroid operated between 1999 and 2008 in our institution...

Oncocytes are epithelial cells characterized by their abundant eosinophilic and finely granular cytoplasm. Their histologic appearance is due to excessive amounts of cytoplasmic mitochondria. Oncocytes generally occur in the setting of benign neoplasms. Oncocytomas, or tumors composed primarily of oncocytes, are typically found in the kidneys. Other common sites include the salivary, thyroid, and parathyroid glands. Oncocytic metaplasia has only been rarely reported in various cutaneous neoplasms. We report a case of an elderly male presenting with a 5 millimeter erythematous papule on his left scalp, who underwent a shave biopsy showing a nodular, dermal-based adnexal tumor with prominent ductal differentiation, composed of multiple small, well-formed lumina surrounded by enlarged, bland-appearing epithelioid cells...

Cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC), which has a better prognosis, is seen mostly in the setting of familial adenomatous polyposis (FAP). The cytomorphology of CMV-PTC is diverse; hence, it could be mistaken for other thyroid neoplasms with bad prognostic outcome. This case is of a 24-year-old female diagnosed with polyposis coli found to have thyroid nodules at screening ultrasonography. Aspirated thyroid smears were hypercellular with epithelial cells arranged in monolayer sheets, papillae with discohesion, and spindling of cells at the edges, cribriform clusters, and cell morules...

BACKGROUND: Thyroid nodule is one of the most common endocrinopathies occurring children and adolescents. Though thyroid nodule is rare in the pediatric age group, the rate of malignancy is much higher in this age group compared to adult population. AIM: The objective is to study the application of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) in pediatric patients and compare the findings with histology. MATERIALS AND METHODS: A total of 218 cases younger than 18 years were studied in a 4-year period from August 2010 to July 2014...

AIM: It is a diagnostic challenge to differentiate benign and malignant cytology in the presence of Hürthle cells. In our previous study, it was determined that in fine needle aspirations (FNA), the malignancy outcome of the Hürthle cells containing group tend to be papillary thyroid carcinoma (PTC) in a higher percentage. The most common misinterpretation is caused by PTC cells with large cytoplasm-like Hürthle cells. The aim of this study is to predict histologic outcome of the nodules, which have Hürthle cells in FNA according to cytological, clinical features, and BRAF(V600E) mutation status...

The hobnail variant (HV) of papillary thyroid carcinoma (PTC) is an unusual entity recently proposed as an aggressive variant of PTC. We describe the pathologic and molecular features of 2 cases of HV of PTC. Both tumors presented in stage III (pT3 pN1a M0). The first case was diagnosed in a 62-year-old man, whereas the second was in a 53-year-old woman. Both patients were treated with total thyroidectomy and radioactive iodine. The primary tumors showed a hobnail/micropapillary pattern in ≥50% of the neoplasm, and positivity for TTF-1, TTF-2, thyroglobulin (TG), cyclin D1, and p53...

Water-clear cell adenoma (WCCA) of the parathyroid gland is an exceedingly rare neoplasm. To date, 17 cases have been reported in the literature, with only one of them being intrathyroidal. Here we report a case of a 34-year-old woman who presented for evaluation of a goiter and was found to have a thyroid nodule and abnormal thyroid function tests (TFT). Fine needle aspiration biopsy of the nodule revealed thyroid follicular cells without atypia and subsequent Afirma® Gene Expression Classifier (GEC) testing results were suspicious for malignancy...

BACKGROUND: Secondary malignancies of salivary glands (SMSGs) are among the most common malignant neoplasms to involve the salivary glands. Fine-needle aspiration biopsy (FNAB) of SMSG can present diagnostic challenges. The current report presents the largest such FNAB series to date. METHODS: A search of the pathology database from 6 academic institutions identified 184 FNAB cases of nonlymphomatous SMSG. RESULTS: Of the 184 cases, 171 were of the parotid glands, and 13 were of the submandibular glands; 130 patients were men, and 54 were women, and the mean patient age at diagnosis was 68 years...

The prostate-specific membrane antigen (PSMA) is expressed by both prostate cancer and other neoplasms. We report the case of a 65-year-old man with castration-resistant metastatic prostate cancer who underwent Ga-PSMA ligand PET/CT for restaging of disease. Ga-PSMA ligand accumulation was noted in a thyroid lesion, suspicious for thyroid malignancy on complementary ultrasound. Subsequent resection and histopathological analysis showed follicular thyroid adenoma with PSMA expression in tumor neovasculature endothelial cells, but not in thyroid epithelial cells...

Thyroid carcinoma (TC) is the most common endocrine cancer and its incidence has been increasing globally over the past decades. With the development of the genetic technology, more and more evidences showed that many genes affect the biological behaviors of TC, making sense to early diagnosis, predicting the prognosis and targeted therapy for TC. BRAF mutation is specific to papillary thyroid carcinoma (PTC). It can not only predict the prognosis, but also have diagnosis value. RET rearrangements are identified as a specific genetic event in PTC...

The detection of thyroid nodules, consisting of different diseases, represents a common finding in population. Their evaluation and diagnosis are mostly achieved with fine-needle aspiration cytology (FNAC). Even though the majority of thyroid nodules are correctly diagnosed, a total of 25% to 30% of them are classified "indeterminate" comprising lesions with varying risk of malignancy and different types of management. Although the number of thyroid FNACs, including small lesions, is increasing due to the reliance upon sonographic and cytologic interpretations, there are issues concerning cytomorphologic interpretation and interobserver reproducibility...
