  • Fine needle aspiration cytology as a diagnostic workup of parotid gland tumor is a simple and useful method. Although fine needle aspiration cytology could not predict accurate diagnosis in all cases, it is usually helpful in differentiating malignancy and benign lesions. A 35-year-old female was found to have a parotid mass for 1 year. Preoperative evaluation including computed tomography and magnetic resonance imaging were non-diagnostic, but, fine needle aspiration cytology on parotid mass showed the suspicion of a low-grade mucoepidermoid carcinoma. Superficial parotidectomy and selective neck node dissection were done based on cytology. However, final pathological examination confirmed benign pleomorphic adenoma. Here, the diagnostic accuracy and cautions in interpretation of result of fine needle aspiration cytology is discussed with respect to the case.

  • Thymoma is the most common anterior mediastinal tumor in adults. Rarely, it is presented as the anterior neck mass, commonly located in the anterolateral aspect of the neck or adjacent to the thyroid. We experienced two cases of fine needle aspiration cytology of thymoma, mimicking thyroid mass. The first case was an ectopoic cervical thymoma in a 31-year-old female. The fine needle aspiration cytology was misinterpreted as reactive hyperplasia of lymph node. But the histologic diagnosis was thymoma, predominantly lymphocytic type. The second case was an invasive thymoma in a 66-year-old female, who complained a large anterior neck mass. The fine needle aspiration cytology revealed biphasic population of some clusters of epithelial cells and scattered lymphocytes. The cytologic diagnosis was thymoma and was confirmed as invasive thymoma after the biopsy. Therefore, when the cytologic feature of anterior neck mass shows the both lymphocyte and epithelial component, the differential diagnosis should Include the possibility of thymoma.

  • Fibromatosis colli is a benign fibrous tissue proliferation of sternocleidomastoid muscle, which is usually observed during the first month of life, often associated with congenital torticollis. It should be differentiated from other neck masses in infants because the usual initial treatment of fibromatosis celli is conservative management and invasive therapy should be avoided. Fine needle aspiration cytology provides an excellent minimally invasive diagnostic way for evaluation of infantile neck masses. We describe three cases of fibromatosis colli diagnosed by fine needle aspiration cytology. All of them were younger than one month and presented as a neck mass. Clinical impressions were malignant tumors in two cases and fibromatosis colli in one case. Fine needle aspiration cytology revealed benign and mature fibroblasts and atrophic striated muscle fibers. The cytologic diagnosis was fibromatosis colli or benign fibous lesion.

  • Ki-1 lymphoma is a sort of high grade large cell lymphoma and defined on the basis of the reactivity of the tumor cells with monoclonal antibody Ki-1. On fine needle aspiration cytology, the reported case is rare and the differential diagnosis is not easy, especially from undifferentiated carcinoma and Hodgkin's lymphoma. We experienced a case of fine needle aspiration cytology of Ki-1 positive large cell lymphoma in a 61-year old male patient. Fine needle aspiration cytology from the cervical lymph node disclosed hypercellular smears with large single cells on polymorphous lymphoid background. The tumor cells had abundant dense cytoplasm and large nuclei with Irregular profiles. Although most cells were mononuclear binucleated and multilobed/multinucleated cells were also seen Immunohistochemistry was done and revealed strong positive staining for Ki-1 antigen.

  • Fine needle aspiration cytology (FNAC) of thyroid gland lesions has become a routine diagnostic method. And fine needle aspiration cytology is considered a safe, reliable and cost-effective means of selecting thyroid nodules with risk for malignancy. However, fine needle aspiration cytology of the thyroid may cause hemorrhage, infection, or trauma to adjacent structures. Hemorrhage sufficient to cause tracheal compression has not been reported. So we present a case of anterior neck hematoma causing tracheal compression after FNAC of the thyroid nodule.

  • Fine needle aspiration has been effectively being applided to pediatric tumors since it renders a rapid diagnosis with minimal intervention. This measure is especially required for the large pediatric mass, which needs preoperative chemotherapy or radiotherapy to shrink the tumor to an operable size. A case of neuroblastoma of mediastinum, stage IV diagnosed by CT-guided FNA is described.

  • Fine needle aspiration biopsy(FNAB) has been used for many decades in the diagnosis of benign and malignant tumors of thyroid gland. Complications of thyroid fine-needle aspiration biopsy(FNAB) are extremely rare. Hematoma formation is the most commonly encountered complication. However, massive intrathyroid unilateral hemorrhage and hematoma formation inducing upper airway distress rarely occurs. Here, we report two cases diagnosed as having hematoma that caused upper airway distress after FNAB for thyroid nodule.

  • We experienced a case of primary hepatic actinomycosis which was initially diagnosed by means of fine needle aspiration. The patient was a 31-year-old emaciated man with a 2-month history of 10 kg weight loss, right upper quadrant pain and flank pain. The liver was palpable and tender on physical examination. Computerized tomography scan of the liver showed two ill-defined hypodense masses in gallbladder fossa and inferior pole of right lobe. Hepatocellular carcinoma was clinically suspected. A CT-guided fine needle aspiration was peformed. Microscopically, smears showed numerous radiating clusters of filamentous bacteria with many neutrophils and monocytes in necrotic background. The symptoms were improved by incision and drainage and massive administration of penicillin.

  • Langerhans' cell histiocytosis is a relatively rare disorder of children, characterized by abnormal proliferation of Langerhans' cells. It usually presents as multiple osteolytic lesion with lymphadenopathy or cutaneous manifestations. We experienced a case of Langerhans' cell histiocytosis involving bone and lymph node, diagnosed by fine needle aspiration cytology of the lymph node. The patient was a 10-year old girl with left inguinal lymphadenopathy. Fine needle aspiration cytology from the lymph node disclosed very cellular smear consisted of Langerhans' cells, eosinophils and lymphocytes. The Langerhans' cells had eccentric oval to reniform shape nuclei with grooving and abundant pale cytoplasm. The diagnosis was confirmed later by histologic study of bone lesion.

  • Human sparganosis is a rare parasitic disease in which the larval cestode proliferates in the various organs in the body. It usually presents as a subcutaneous or soft tissue mass. By fine needle aspiration this lesion can be diagnosed with its characteristic cytologic findings. We experienced 3 cases of sparganosis diagnosed by the fine needle aspiration. Aspirates were taken from subcutaneous mass in the abdomen and both thighs respect ively. The aspirates showed a portion of body of sparganum with numerous calcospherules, smooth muscles and tegmental cells. They also revealed granulomas with various inflammatory infiltration of eosinophils, neutrophils, lymphocytes and plasma cells.
