Objectives: The tall cell variant is an uncommon variant and has been known as more aggressive form of papillary thyroid carcinoma (PTC). Owing to the rarity of these thyroid cancers, their clinical behavior remains incompletely understood. To elucidate the clinicopathologic characteristics of tall cell variant, we retrospectively reviewed our surgical experience of patients with tall cell variant. Methods: Between August 1993 and July 2004, a total of 11 consecutive patients who were pathologically diagnosed with tall cell variant of papillary thyroid carcinoma were enrolled in this study. All patients underwent total (8 cases) or subtotal thyroidectomy (3 cases) with central compartment node dissections. The lateral neck dissection was added in 6 patients. After the operation, neck ultrasound and serum thyroglobulin were checked regularly during the follow-up period. Results: The mean age of the patients was 56.6years (range, 30-74years) at the time of diagnosis. 3 patients were men, and 8 were women. The mean diameter of tumor was 3.7cm(range, 1.5-6.0cm), and 6 patients had lateral neck node metastasis. Extrathyroidal extension was seen in 5 patients (45%). Loco-regional recurrence was found in 2 patients (18%), and distant metastasis in 1 patient (9%). The 5-year disease free survival rate was 68%. Conclusion: The tall cell variant of papillary thyroid carcinoma is an uncommon disease. Clinicopathologic feature and prognosis of this disease show more aggressive behaviors than ordinary papillary thyroid carcinoma. More aggressive treatment and close follow-up should be undertaken in the tall cell variant of papillary thyroid carcinoma.

갑상선 미세유두암종은 영상 기술의 발달로 더욱 그 빈도가 높아질 것이 예상되므로 진단의 정확도를 높이는 것이 무엇보다 중요하다. 갑상선 미세 유두암종으로 진단 받은 37예를 대상으로 galectin-3, cytokeratin 19와 HBME-1 분자 표지자들을 면역조직화학적 염색을 시행한 결과 cytokeratin 19에서 1예를 제외하고 모든 예에서 갑상선 종양 세포에서 발현하였다. Galectin-3는 갑상선 종양 세포의 세포질에 강하게 염색되었으며 cytokeratin 19는 세포질과 세포막을 따라 강하게 염색되었다. HBME-1은 종양 세포의 세포막에 강하게 염색되었으나 3가지 분자 표지자 모두 정상 갑상선 조직에서는 염색되지 않았다. 이상의 결과에서 볼 때 galectin-3, cytokeratin 19와 HBME-1은 병리조직학적 소견과 함께 갑상선 미세 유두암종을 진단함에 있어 보조적 도움이 되는 표지자로 생각된다.

Background: Inflammatory hematological parameters like the neutrophil/lymphocyte (N/L) ratio have been investigated in many cancer types and significant relationships found with prognosis, for example. The aim of this present study was to investigate the impact of hematological parameters notably on N/L ratio and mean platelet volume (MPV) in papillary thyroid cancer cases. Materials and Methods: A total of 79 patients who underwent a thyroidectomy operation in Findikli, Goiter Research and Treatment Center during 2011-2015 period were enrolled in the study, 41 with papillary thyroid cancer and 38 with benign goiter confirmed by pathological examination. We collected clinical and laboratory data for the patients from hospital records retrospectively. Blood samples taken at admission were assessed for parameters compared between the groups. Results: No significant differences between papillary thyroid cancer and benign goiter groups were apparent in terms of age, the N/L ratio, MPV, white blood cell count (WBC), red blood cell count (RBC), hemoglobin, hematocrit, platelet, neutrophil, lymphocyte, red blood cell distribution width (RDW) and platelet crit (PCT) levels (p>0.05). Only the level of platelet distribution width (PDW) significantly differed, being lower in the papillary cancer group (p<0.05). Conclusions: No significant relationship between papillary thyroid cancer and inflammatory hematological parameters including in particular the N/L ratio and MPV. The relevance of the PDW values remains unclear.

We present the cytologic features of a case of solid and papillary neoplasm of the pancreas. Cytologically, the tumor was composed of a monotonous population of polygonal cells containing eccentrically located round nuclei with one or two distinct small nucleoli and a finely stippled chromatin pattern. The tumor cells were similar to those of the islet cell tumor and showed isolated loosely aggregated and solid sheets or large cell clumps. The large cell clumps revealed a branching papillary structure containing fibrovascular central core, which is characteristic histologic feature of solid and papillary neoplasm of the pancreas. This case was confirmed by tissue examination including histochemical, immunohistochemical and electron microscopical studies. Ultrastructurally, the tumor cells contained a few membrane- bound electron dense granules.

Background: Papillary thyroid cancer or papillary thyroid carcinoma (PTC) is the most common thyroid cancer. The fact that it occasionally occurs in women aged 30-40 years old suggests that genetic alterations are involved its genesis. Recently, activator mutations in BRAF gene have been relatively frequently discovered. Materials and Methods: In this study, we tested 63 DNA samples from PTC patients to identify the V600E mutation frequency in the Ahvaz population. DNA was isolated from formalin fixed paraffin-embedded (FFPE) PTC tumor tissues. Genotyping was performed by PCR-RFLP and confirmed by direct DNA sequencing of a subset of PCR products. PCR-RFLP data were reported as genotype frequencies and percentages. Results: Forty nine out of 63 patients (77.8%) had a mutated heterozygote form while 14 (22.2%) showed normal genotype but none demonstrated a mutant homozygote genotype. The frequency of V600E mutation was significantly high in PTC patients. Conclusions: These findings support involvement of V600E mutations in PTC occurrence in Iran. Assessment of correlations between BRAF V600E mutations and papillary thyroid cancer progression needs to be performed.

Objectives: Thyroid cancer is the most common cancer for female in Korea. This study aims to report the effects of Korean medicine on complications after total thyroidectomy and neck dissection in the papillary thyroid carcinoma. Methods: The 3 patients with papillary thyroid carcinoma were treated by Korean medicine such as acupuncture, moxibustion and pharmacopuncture therapy. We evaluated the results of treatments by change of symptoms. Results: After treatments such as acupuncture, moxibustion and pharmacopuncture therapy except herb medicine, the symptoms of complications after total thyroidectomy and neck dissection were improved. Conclusions: This study shows that Korean medicine has effects on complications after total thyroidectomy and neck dissection in the papillary thyroid carcinoma.

Papillary carcinoma of thyroid is the most common thyroid carcinoma carrying better prognosis than the other thyroid carcinoma. Among the variants in the papillary thyroid carcinoma, the tall cell variant and diffuse sclerosing variants have more aggressive behavior than the classic papillary carcinoma. Recently, a new variant of papillary carcinoma has been reported which was named warthin-like tumor of the thyroid because of its close histologic resemblance to a tumor encountered in the salivary gland, carrying favorable prognosis. Since then, in English literature, a few cases have been reported, but in Korea have not been reported yet. We report a case of warthin-like tumor of the thyroid. A 38 year-old woman who had neck mass, was administered for thyroid surgery due to suspicious thyroid cytology. Right total thyroidectomy and left subtotal thyroidectomy with central compartment node dissection was performed. Histologic diagnosis was made as a Warthin-like tumor of the thyroid.

Occult papillary adenocarcinoma of the thyroid is known to be indolent, slow metastatic, and has a good prognosis. Occult thyroid carcinoma presenting as a blood-borne metastasis without obvious cervical lymph node involvement is extremely rare. A 65-year-old male patient was visited for hoarseness, dysphagia, and shortness of breath. Bronchoscopy with biopsy revealed a papillary carcinoma of thyroid by immunohistochemical staining. Head & neck CT revealed that involving both the upper esophagus and the posterior tracheal wall, extending into the mediastinum along the upper thoracic spine at $T_1-T_2$. We have experienced a rare case of occult papillary carcinoma which invaded the trachea, esophagus and fascia of thoracic spine. Treatment was initiated with radioactive iodine and external bean therapy.

Chromatin texture, which partly reflects nuclear organization, is evolving as an important parameter indicating cell activation or transformation. In this study, chromatin pattern was evaluated by image analysis of the electron micrographs of follicular and papillary carcinoma cells of the thyroid gland and tested for discrimination of the two neoplasms. Digital grey images were converted from the electron micrographs, nuclear images, excluding nucleolus and intranuclear cytoplasmic inclusions, were obtained by segmentation; grey levels were standardized; and grey level histograms were generated. The histograms in follicular carcinoma showed Gaussian or near-Gaussian distribution and had a single peak, whereas those in papillary carcinoma had two peaks(bimodal), one at the black zone and the other at the white zone. In papillary carcinoma, the peak in the black zone represented an increased amount of heterochromatin particles and that at the white zone represented decreased electron density of euchromatin or nuclear matrix. These results indicate that the nuclei of follicular and papillary carcinoma cells differ in their chromatin pattern and the difference may be due to decondensed chromatin and/or matrix substances.

Common bile duct stones are an unusual occurrence in children. Endoscopic retrograde cholangiopancreaticography and endoscopic papillary sphincterotomy are excellent tool for diagnosis and therapy. Bleeding after endoscopic papillary sphincterotomy occurs in approximately 0.5~12% of procedures. We experienced a case of common bile duct stone in 5-year-old boy. After endoscopic papillary sphincterotomy, the stone was passed. 5 days after the procedure bleeding occurred, but it was controlled spontaneously.
