Salivary and lacrimal gland dysfunction is relatively frequent after radioiodine therapy. In most cases this is a transient side effect, but in some patients it may persist for a long period or appear late. Radioiodine ($^{131}I$) therapy is often administered to patients following total thyroidectomy to treat well-differentiated follicular cell-derived thyroid cancer. In addition to the thyroid, $^{131}I$ accumulates in the salivary glands, giving rise to transient or permanent salivary gland damage. Salivary gland dysfunction following radioiodine therapy can be caused by radiation damage. But, it also may be associated with $Sj{\ddot{o}}gren$ syndrome (SS) developed after radioiodine therapy. It would be recommended that the evaluation for SS including anti-SSA/Ro and anti-SSB/La should be considered before and after radioiodine therapy.

Background: Fine-needle aspiration cytology serves as a safe, economical tool in evaluating thyroid nodules. However, about 30% of the samples are categorized as indeterminate. Hence, many immunocytochemistry markers have been studied, but there has not been a single outstanding marker. We studied the efficacy of CD56 with human bone marrow endothelial cell marker-1 (HBME-1) in diagnosis in the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) category III. Methods: We reviewed ThinPrep liquid-based cytology (LBC) samples with Papanicolaou stain from July 1 to December 31, 2016 (2,195 cases) and selected TBSRTC category III cases (n=363). Twenty-six cases were histologically confirmed as benign (six cases, 23%) or malignant (20 cases, 77%); we stained 26 LBC slides with HBME-1 and CD56 through the cell transfer method. For evaluation of reactivity of immunocytochemistry, we chose atypical follicular cell clusters. Results: CD56 was not reactive in 18 of 20 cases (90%) of malignant nodules and showed cytoplasmic positivity in five of six cases (83%) of benign nodules. CD56 showed high sensitivity (90.0%) and relatively low specificity (83.3%) in detecting malignancy (p=.004). HBME-1 was reactive in 17 of 20 cases (85%) of malignant nodules and was not reactive in five of six cases (83%) of benign nodules. HBME-1 showed slightly lower sensitivity (85.0%) than CD56. The specificity in detecting malignancy by HBME-1 was similar to that of CD56 (83.3%, p=.008). CD56 and HBME-1 tests combined showed lower sensitivity (75.0% vs 90%) and higher specificity (93.8% vs 83.3%) in detecting malignancy compared to using CD56 alone. Conclusions: Using CD56 alone showed relatively low specificity despite high sensitivity for detecting malignancy. Combining CD56 with HBME-1 could increase the specificity. Thus, we suggest that CD56 could be a useful preoperative marker for differential diagnosis of TBSRTC category III samples.

Background: The purpose of this study was to provide epidemiological and histological data of thyroid cancers in Togo. Materials and Methods: This was a retrospective cross-sectional study of cases of thyroid cancers diagnosed from 2000 to 2014 (15 years) at the pathology laboratory of the Sylvanus Olympio Teaching Hospital of $Lom{\acute{e}}$. All cases of review of a thyroid sample (biopsies, surgical specimens) were collected from the data records of that laboratory. Results: Thyroid cancers represented 1.1% (7930cases) of all cancers registered during the study period. Mean age was $45.4{\pm}0.3$ years and the proportion of females was 78.3%. We identified 92.4% carcinomas and 7.6% lymphomas. Carcinomas were well differentiated in 80 cases and were dominated by the papillary type (47 cases). Metastasis was observed in 13% of patients. The pTNM classification evaluated in 18 cases showed a predominance of grade I (13 cases). Lymphomas were dominated by lymphoma diffuse large B-cell (5 cases). Conclusions: This study is the first global standard for thyroid cancer pathology in Togo. The high frequency of follicular form suggests an unrecognized iodine deficiency. The improvement of the technical platform of the LAP (immunohistochemistry) will increase the diagnosis of rare forms of thyroid cancer.

Renal cell carcinoma is the third most common metastatic tumor to the bone and soft tissues of the head and neck. The common sites of metastatic renal cell carcinoma in head and neck region are nasal cavity, paranasal sinuses, oral mucosa, gingiva, tongue, palate, lip as the favored site. The present paper deals with one patient with metachronous oral tongue, nasal cavity and suspicious brain metastases after 2 years of renal cell carcinoma nephrectomy. Also, the patient had history of total thyroidectomy for thyroid follicular carcinoma. Total excision of nasal cavity and tongue mass were performed. Therapeutic aspects are briefly reviewed in literature.

Sono-guided fine needle aspiration (FNA) of the thyroid is widely used, but the aspirated samples are typically not well preserved and low cellularity makes diagnosis difficult in many cases. The object of the current study is to evaluate the adequacy and diagnostic accuracy of the use of $SurePath^{TM}$ liquid-based cytology (SP-LBC) in the sonoguided fine needle aspiration of the thyroid nodule and to compare its use with that of the use of a conventional smear (CS). A total of 172 sono-guided FNAs of thyroid nodules from April to June, 2006 were prepared by the use of the split method with either SP-LBC or CS; the samples were stained with the use of hematoxylin-eosin (H&E) and Papanicolaou (Pap) stains. A cyto-histological correlation was performed in 69 (30 SP and 39 CS) cases that had been histologically confirmed. The rate of producing unsatisfactory slides by the use of the SP-LBC method (9.3%) was less than that of the use of the CS method (20.9%). The diagnostic accuracy of the SP method (93.3%) was better than that of the CS method (85.3%). The sensitivity and specificity of the SP method (94.4% and 92.3%) was better than that of the CS method (83.3% and 70%), respectively (p < 0.05). The CS of sono-guided aspirated specimens had some unavoidable limitations related to inadequate sampling such as a bloody background, low cellularity and an indication that some clinicians smeared many useless slides (averaging four to ten slides), and that most slides showed only blood that included few follicular cells. The SP method resulted in more thinly smeared slides and showed cleaner background and greater cellularity than the use of the CS method. Each follicular cell shows superior nuclear detail, and more distinct cytoplasmic features than with the use of the CS method. SP-LBC appears to be an easy, highly accurate, and reliable cytological method for employ for a diagnostic approach of thyroid disease and thyroid nodules. The SP-LBC method is a suitable alternative to the CS method to overcome diagnostic difficulties.

A sex cord tumor with annnular tubules is a relatively rare ovarian neoplasm. The cytologic findings from a fine needle aspiration biopsy of neck metastasis of a sex cord tumor with annnular tubules are described. The origin of the neck metastasis was the right ovary, and the tumor was diagnosed six years ago. The cytologic findings were characterized by tumor cells arranged in solid or follicular patterns. The tumor cells formed rosette-like or complex tubular structures with central rounded or coalesced hyaline materials. It was difficult to distinguish this tumor cytologically from granulosa cell tumor, thyroid follicular neoplasm, Sertoli-Leydig cell tumor, and Brenner tumor, but complex tubular structures were helpful in discriminating between these tumors.

The indolent course of most thyroid papillary carcinomas, even the presence of regional lymph node metastasis, make them unique among human malignant head and neck cancers. Age, sex, extracapsular invasion and anaplastic change are known to be correlated with prognosis. The purpose of this study is to clarify the significance of DNA content analysis as a prognostic factor. Twenty five thyroid papillary carcinomas were possible to be examined by flow cytometric analysis using fresh surgical specimens and three nodular hyperplasias and seven follicular adenomas were included as control group. The results were as follows: l) All of twenty five thyroid papillary carcinomas showed diploidy. 2) S-phase fraction was $1.94{\pm}2.77%$ in normal control group and $2.60{\pm}2.66%$ in papillary carcinoma group. The proliferation index was $8.44{\pm}3.89%$ in normal control and $7.70{\pm}3.63%$ in papillary carcinoma group with even low value. 3) Age, sex, extracapsular spread and lymph node metastasis showed no significant difference. In conclusion, low proliferative activity of thyroid papillary carcinomas are thought to be related with good prognosis.

The increased use of thyroid fine needle aspiration(FNA) has re-focused on $H\"{u}rthle$ cell lesions. The cytologic diagnosis of $H\"{u}rthle$ cell tumor is a challenge due to the presence of $H\"{u}rthle$ cells in non-neoplastic lesions and the inability to differentiate between benign and malignant $H\"{u}rthle$ cell tumor. We report a case of $H\"{u}rthle$ cell adenoma(HCA) un a 68-year old woman, with review of the cytopathologic findings. FNA revealed loosely cohesive or sheets of large oval to polygonal $H\"{u}rthle$ cells containing abundant granular cytoplasm. The hustopathologic examination confirmed the diagnosis of HCA with follicular growth pattern. Ultrastructurally, the cytoplasm was packed with variable sized mitochondria.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.

본 연구는 포유동물 갑상선내에 출현하는 PF cell의 형태학적 특징을 밝히기 위하여 사람을 비롯한 포유동물 5목 9종 (영장목, 사람; 우제목, 소, 돼지, 흑염소; 식육목, 개; 설치목, 흰쥐, 마우스, 다람쥐; 토끼목, 집토끼)을 재료로 하여 이 세포의 분포상태, 형태 및 염색성을 비교 관찰하여 다음과 같은 결과를 얻었다. 1. PF cell의 출현수는 종에 따라 유의한 차이를 보였으며, 단위면적당 출현수는 개에서 가장 많았으며, 그 다음이 흰쥐, 다람쥐, 마우스, 집토끼, 소, 돼지, 흑염소, 사람의 순서로 적었다. 2. PF cell의 갑상선내의 분포상태를 보면 소, 집토끼, 다람쥐 및 마우스의 경우는 선엽의 부위에 따라 유의한 차이를 보였으며 개, 사람, 돼지, 흑염소 및 흰쥐의 경우는 유의한 차이는 아니나 부위에 따라 다소 차이를 보였다. 개에서는 선엽전체에 걸쳐 비교적 고르게 분포하였고, 흰쥐의 것은 각 부위의 중심부에 모여 있었다. 흑염소와 다람쥐의 것은 후부에 더 많았다. 마우스와 집토끼의 것은 선엽의 중간부에 많이 출현하되 마우스의 것은 주로 중심부에, 집토끼의 것은 후외측부위에 더 많았다. 사람, 소 및 돼지의 것은 중상부와 후상부에 많이 분포하되 사람과 소의 것은 주로 중심부에 더 모여 있었으며 돼지의 것은 곳곳에 밀집되어 나타났다. 3. PF cell의 출현 위치관계를 보면 개의 경우는 대부분 소포사이에 위치하며 무리를 이루는 경우가 많았지만, 집토끼의 것은 소포내 또는 소포질과 소포사이의 결합조직내에 두루 분포하되 무리를 이루고 있는 것이 자주 관찰되었고, 사람, 소, 돼지, 흑염소, 흰쥐, 마우스 및 다람쥐의 경우는 대부분 소포내 또는 소포곁에 낱개로 산재하였다. 4. PF cell의 모습은 식육목인 개의 것만 구형 또는 난원형이고 기타 동물의 것들은 방추형, 원추형, 난원형, 구형 및 세포질 돌기를 가진 세장형등 매우 다양한 모습이었다. 5. 세포의 크기는 소, 개 및 돼지의 것이 다소 크고, 집토끼, 사람 및 흑염소의 것이 중등대였으며 흰쥐, 마우스 및 다람쥐의 것이 다소 작은 편이었다. 6. PF cell내에 함유되어 있는 분비과립의 양에 따른 형별 세포의 출현비율에서 볼때 다과립형 세포가 많은 동물은 돼지, 소, 개 및 다람쥐였고, 희과립형 세포가 많은 동물은 마우스, 흰쥐 및 사람이었다. 7. 은친화성 도은법에서는 모든 동물에서 양성 반응을 볼 수 없었으나, 기타 3가지 염색법에서는 종에 따라 차이는 보이나 모두 양성 반응을 보였다. 즉, 개, 소 및 돼지의 PF cell은 3가지 염색에서 모두 중등도 이상의 강한 양성 반응을 보였고, 흑염소의 것은 Grimelius 은호성 도은법과 HCl-toluidine blue법에서, 집토끼와 다람쥐의 것은 HCl-toluidine blue 법에서, 흰쥐의 것은 Grimelius 은호성 도은법과 HCl-lead hematoxylin법에서, 마우스의 것은 HCl-lead hematoxylin법과 HCl-toluidine blue법에서 중등도 이상의 양성반응을 보였으며, 사람의 것은 3가지 염색법에서 모두 약한 양성 반응만을 나타내었다. 8. 이상의 소견을 종합하면, PF cell의 분포 위치 및 형태등에 종간의 차이를 볼 수 있었다. 또 조직학적 식별을 위한 염색법에 있어서는 양성 반응도가 다르기 때문에 실험 목적에 따라 염색법을 선택하여야 할 것으로 사료된다.
