The distinction between matrix-producing metaplastic carcinoma (MPMC) and pleomorphic adenoma (PA) is sometimes unclear in breast pathology, especially on core needle biopsy. Herein, we presented a 66-year-old woman with MPMC of the breast that looked like PA on fine-needle aspiration cytology (FNAC). On FNAC, the appearance of abundant myxoid matrix along with cellular clusters composed of mon...

A thyroid abscess caused by acute suppurative thyroiditis (AST) is a rare form of thyroid nodule, and is most common in children, particularly in the first decade of life. The echotexture of an abscess may vary depending on the extent of internal debris or hemorrhage and on the peripheral and interval vascular flow; thus, a definitive diagnosis of AST is difficult to establish. The present stud...

In 175 patients presenting with thyroid nodules, the diagnostic value in management of fine needle aspiration and cytology (FNAC), pertechnetate (99mTc) scanning and ultrasound imaging was examined. In 82 patients, the diagnosis was confirmed at operation; in the remaining 93, there was a follow-up period of at least 2 years. Thyroid cancer was found in 13 patients. For FNAC the sensitivity, sp...

Thyroglossal duct cyst is the most common developmental abnormality encountered in the neck. Carcinoma arising in a thyroglossal duct cyst is a rare occurrence, and was first reported by Ucherman in 1910, the most common being papillary carcinoma. The incidence of primary papillary carcinoma arising in thyroglossal duct cyst is less then1%. We report a case of papillary thyroid carcinoma occurr...

Leprosy is a chronic infection affecting mainly the skin and peripheral nerve. Pure neuritic form of this disease manifests by involvement of the nerve in the absence of skin lesions. Therefore, it can sometimes create a diagnostic problem. It often requires a nerve biopsy for diagnosis, which is an invasive procedure and may lead to neural deficit. Fine needle aspiration cytology (FNAC) of an ...

Introduction: Thyroid nodules are a common clinical entity found among the adult general population. With increasing use of imaging investigations like ultrasonography, there has been a significant rise in the detection of non-palpable thyroid nodules that require further evaluation and management. The routine use of FNAC has reduced the number of unnecessary surgical procedures for thyroid nod...

Fine needle aspiration cytology (FNAC) is a useful pre-operative procedure in pediatric renal tumors. It is a safe technique that does not upstage the tumor and permits positive diagnosis of Wilm’s tumor in almost all aspirates with use of immunocytochemistry for cytokeratin and WT-1. Advanced information on diagnosis of Wilm’s tumor, especially, the presence of stroma predominance or anaplasti...

Background and Objective: Fine needle aspiration cytology (FNAC) is a well-established method of diagnosis in palpable masses of various sites. This study was conducted to evaluate the usefulness of FNAC as a diagnostic tool in the management of patients with cervical lymphadenopathy. Patients and Methods: Totally 178 patients admitted to Loghman-Hakim Hospital , Tehran, Iran, with cervical mas...

background & objective: abdominal cutaneous and subcutaneous nodules are uncommon lesions which may be benign or malignant. majority of the malignant nodules are metastatic in origin and may be the initial presentation of primary malignancy, hence an early diagnosis is important. our aim was to find out the spectrum of lesions (both non-neoplastic and neoplastic) that present as cutaneous a...

Abstract Background Axillary lymph node involvement is one important prognostic factor in breast cancer, but the way to access this information has been modified over years. This study evaluated if axillary ultrasound (US) coupled with fine-needle aspiration cytology (FNAC) can accurately predict clinically relevant metastasis patients and thus assist clinical decisions Methods a cross-sectiona...
