Background and Objectives: Anaplastic thyroid carcinoma (ATC) is commonly related with concurrent differentiated thyroid carcinoma (DTC). We aimed to examine the clinicopathologic characteristics, prognosis and gene expression of DTC with anaplastic foci. Materials and Methods: Eighteen patients with DTC with anaplastic foci were enrolled in this study. To compare the clinicopathologic characteristics and prognosis of anaplastic foci subjects with conventional ATC or DTC, we additionally included 12 ATC and 1030 DTC patients who diagnosed during same period. Immunohistochemistry was performed to check the gene expression in anaplastic foci and DTC component. Results: In anaplastic foci group, tumor size was larger ($2.5{\pm}1.3$ vs. $1.2{\pm}0.9cm$, p=0.001), distant metastasis was more frequent (11.1 vs. 0%, p=0.000) and 1-year survival rate was low (88.9 vs. 100%, p=0.000) than DTC group. In contrast, compared with ATC group, anaplastic foci group showed younger age at diagnosis ($50{\pm}16$ vs. $63{\pm}18years$, p=0.039), smaller tumor size ($2.5{\pm}1.3$ vs. $3.8{\pm}1.4cm$, p=0.027), less distant metastasis (11.1 vs. 41.7%, p=0.084) and longer 1-year survival rate (88.9 vs. 25.0%, p=0.001). Expression of p53 protein was observed in 100% of anaplastic foci, ATC and 12.5% of papillary thyroid carcinoma component. Conclusion: DTC with foci of anaplastic transformation has a worse prognosis than DTC, but a better prognosis than ATC. Our results support that DTC with anaplastic foci was intermediate state from DTC to ATC.

Anaplastic carcinoma of the thyroid gland is one of the most malignant tumors. Recently, DNA ploidy measured by flow cytometry and image analysis has been suggested as an additional useful indicator of tumor behavior. Studies on the occurrence and clinical significance of DNA aneuploidy in anaplastic carcinoma of the thyroid are rare. In this study, the pattern of DNA ploidy was measured by image analysis on Papanicolaou stained slides in four cases of anaplastic carcinoma and also measured by flow cytometry using paraffin blocks in two cases. In all cases of anaplastic carcinoma, DNA aneuploidy was found by image analaysis. By flow cytometry, one case had a diploid peak and the other case had an aneuploid peak. According to the above results, we conclude that anaplastic carcinoma of the thyroid glands have a high incidence of DNA aneuploidy and image analysis using Papanicolaou stained slides is a useful method in detecting DNA aneuploidy.

Anaplastic transformation of differentiated thyroid cancer at distant metastatic sites is extremely rare and has a poor prognosis. It usually occurs in the thyroid gland or cervical lymph nodes. Here we report a case of anaplastic transformation arising at multiple distant metastatic sites including the lung, liver, adrenal gland, bone, and lymph nodes in a patient 3 years after total thyroidectomy for follicular thyroid cancer.

Primary anaplastic oligodendroglioma in brain stem is extremely rare. The authors present a case of a anaplastic oligodendroglioma arising from pons. A 29 year-old male patient was admitted because of cranial nerve palsy and visual disturbance. Neurological examination revealed bilateral sixth and left seventh cranial nerve plasies. Near-total resection of tumor mass was performed through midline suboccipital appraoch. Tumor was not related with choroid plexus and major vessels but it was firmly attached to the fourth ventricle floor. Tumor was considered to be arised from the tegmental portion of pons, growing dorsally into the 4th ventricle. Hitopathological exmination revealed primary anaplastic oligodendroglioma. Postoperative course was uneventful. The authors believe that this type of tumor with dorsally growing pattern can be successfully resected without major neurological deficit.

Anaplastic carcinoma of the thyroid is one of the most malignant tumors and survival for longer than three years after diagnosis is exceptional. Multinucleated giant cells of osteoclastlike appearance are seen un some of the anaplastic carcinoma, but only three cases in which the diagnosis was made by fine needle aspiration (FNA) cytology are reported in the international literature. We experienced a case of anaplastic carcinoma with osteoclastlike giant cells in a 66-yr-old female, diagnosed by FNA cytology. The smears revealed two cell populations: multinucleated giant cells and large polygonal or spindle shaped malignant cells. The FNA cytodiagnosis of anaplastic thyroid carcinoma containing osteoclastlike giant cells was substantiated by subsequent biopsy.

Anaplastic thyroid carcinoma, which is one of the most aggressive tumors of the thyroid, has been seldomly reposted to have altered thyroid function. There have been few reports of patients with anaplastic thyroid cancer presenting in a hyperthyroid state. In the literatures, the mechanism of hyperthyroidism in anaplastic thyroid cancer is supposed that the rapid invasive growth of cancer seems to cause destruction of thyroid tissue and develops a hyperthyroid state, which is thought to be anlalogous to that of subacute thyroiditis and several types of metastatic cancer of the thyroid: rapid tissue necrosis with resultant release of thyroid hormone. Recently, we experienced a case of anaplastic thyroid cancer presenting with rapid growing mass and hyperthyroidism in a 67-year-old woman and report it with the review of the literatures.

Anaplastic carcinoma of thyroid gland account for no more than 10% of thyroid cancer, but it shows extremely poor prognosis. The purpose of this study is to review the outcome of patients with anaplastic carcinoma over the span of 5 years and to determine the patterns of clinical presentation, age, sex and other possible prognostic variables. We analyzed 30 cases of anaplastic carcinoma retrospectively from 1991 to 1995. There were 14 men and 16 women. There age ranged 33 to 75 years with a mean of 61.0 years. Sixteen patients presented with transformationqr of well differentiated carcinoma to anaplastic carcinoma, 1 with rapid in-crease in the size of long standing goiter, 8 with rapidly growing neck mass and 4 with meta static disease. Twenty-eight patients(93.3%) showed cervical lymphnode metastasis at presentation and twenty three patients(76.6%) showed laryngotracheal invasion. Nine patients (30.3%) showed distant metastasis. Treatment modalities included surgical resection, external irradiation, radioactive iodine and systemic chemotherapy. At decision making of treatment plan, we considered completeness of initial surgery, uptake rate of whole body radioactive io-dine scan, locoregional progression and distant metastasis. The median survival was 6.8 months and three cases survived beyond 12 months.

Meningioma without dural attachment usually occurs in the intraventricular region, the pineal region, and the sylvian fissure. However, subcortical meningioma located far from such locations is extremely rare. The authors report a case of subcortical anaplastic meningioma without any dural attachment in a 41-year-old woman.

Multinucleated giant cells of osteoclast-like appearance can be seen in a type of anaplastic carcinoma of thyroid and only a few case reports for fine needle aspiration cytologic findings are found in the literatures. Recently, we experienced a case of anaplastic carcinoma of thyroid with many osteoclast-like giant cells in a 72-year-old woman. The cytologic features and immunohistochemical results are described with special emphasis on differential diagnosis.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has received increasing interest among plastic surgeons as a long-term complication of breast augmentation. Although the prognosis is usually good, mortality is a possible outcome. Most of the cases reported in the past two decades have been from the United States, Europe, and Australia, whereas cases of BIA-ALCL in Asia remain rare. Herein, we describe the first known case of BIA-ALCL in Thailand, in which a 32-year-old woman developed BIA-ALCL 3 years after breast augmentation using textured implants. The patient underwent bilateral removal of the implants and ipsilateral total capsulectomy. This case report-the first of its kind from Thailand-should increase awareness of BIA-ALCL among plastic surgeons in Asia. The true incidence of BIA-ALCL in Asia may be underreported.
