Columnar Cell Carcinoma of the Thyroid: MIB-1 Immunoreactivity as a Prognostic Factor.

We report a case of columnar cell carcinoma of the thyroid. A 47-year-old Japanese man had a nonencapsulated thyroid mass that infiltrated the surrounding tissues extensively. Seventeen months after thyroidectomy he died of respiratory failure resulting from tracheal invasion. An autopsy showed distant metastases to the liver, lung, esophagus, and pancreas. Histologically, the thyroid mass consisted of tall columnar atypical cells with marked nuclear stratification. About one-fifth of tumor cells were immunopositive for MIB-1. The MIB-1 positive index of our case was extremely high, compared with that of ordinary papillary carcinoma. This case indicates that biological growth activity in columnar cell carcinoma may be similar to that of undiferentiated carcinoma of the thyroid, since the MIB-1-positive index is close to each other.

BREAST CARCINOMA METASTATIC TO UTERINE LEIOMYOMA

Toshiaki Manabe; Takashi Fukuya; Chotatsu Tsukayama

Two cases of breast carcinoma metastatic to uterine leiomyoma are presented. A review of literature disclosed fourteen cases of extrapelvic carcinoma with a metastasis to uterine leiomyoma, ten of which were of breast carcinoma. The high incidence of breast carcinoma among such tumors (75%) suggests some intimacy between these two tumors. It is speculated that the common property of their development by estrogenic stimulation may be responsible for the establishment of such an assodation.

Abstract Metastatic lingual tumors are very rare, and hematogenous myocardial metastasis is also relatively uncommon. We report a case of lung adenosquamous carcinoma with metastases to the tongue and the myocardium. A 65-year-old man underwent a partial upper lobectomy for a primary lung cancer in June 1997. He developed a local recurrence and received two courses of radiotherapy, in March and September 1998. A follow-up computed tomography (CT) scan showed a myocardial tumor, suggestive of cardiac metastasis. In October 1998, he began to complain of angina-like chest oppression and showed ischemic changes on electrocardiogram (ECG), and he also developed lingual, subcutaneous, and brain metastases. He died of respiratory failure in December 1998, 20 months after the initial diagnosis of primary lung cancer; metastases to the tongue and myocardium were confirmed by autopsy.

Invasive adenocarcinoma of the prostate mimicking transitional cell carcinoma in urinary cytology. Report of case.

症例は80歳の男性で, 約1年前より前立腺の高分化腺癌のためホルモン剤の投与を受けている. 経過中にきたした肉眼的血尿のため, 尿細胞診検査を受けたところ, 異型性の強い腫瘍細胞塊の出現がみられ, 移行上皮癌の合併と考えられた. その後, 膀胱内に突出する腫瘤部よりの生検で, 腫瘍細胞が免疫組織化学的にProstate-specific Antigen (PSA) 陽性であったため, 低分化前立腺癌の膀胱浸潤と判断した. その尿細胞像をGrade3の移行上皮癌と比較して検討したところ,(1) 背景には壊死が少なく, 異型性のない移行上皮もみられたこと,(2) 異型性の強さに比して結合性が保たれていたことが, 典型的な移行上皮癌よりも, むしろ他の腫瘍の可能性を示唆するものと考えられた. 前立腺癌の経過中の尿細胞診にて, 異型の強い細胞集塊を認めた場合, 既存の前立腺癌がより低分化なものへと形質変化した可能性を念頭に置くことが大事と考えられた.

骨形成を伴う甲状腺乳頭癌16例の穿刺吸引細胞診像を検討した. 正診率は47%で, 乳頭癌全体の正診率と比べかなり低かった. 骨化量が多い症例ほど腫瘍細胞の吸引が困難であったことより, 硬い腫瘤の穿刺吸引においては, たとえ陰性であっても良性と決めつけない方がよいと思われた. 全例において, 塗抹標本内には骨組織は認められなかった. 3例においては, 大小不同や泡沫状の胞体を有する脂肪細胞がみられ, 形態学的に乳頭癌組織内の骨梁間にみられる脂肪細胞に一致するため, そのような脂肪細胞は骨化を伴った乳頭癌の存在を間接的に示唆する所見と思われた.

Re-evaluation of cytologic false negative cases of papillary carcinoma of the thyroid.

Mitsuyoshi Hirokawa; Satoko Nakamura; Yasumasa Monobe; Masamitsu Nakajima; Takuya Moriya; Michio Shimizu; Takashi Fukuya

穿刺吸引細胞診を行った甲状腺乳頭癌の誤陰性例について検討した. 再鏡検の結果, 誤陰性例は112例中39例で, そのうち塗抹標本上に腫瘍細胞がみられなかった真の陰性例は20例 (17.9%) で, 腫瘍細胞が存在したにもかかわらず良性あるいは悪性の疑いと報告した誤判定例は16例 (14.3%) であった. 真の陰性例は腫瘍径が1cm以下の小さい場合 (微小癌), 石灰化や骨化がみられるもの, 肉眼分類では完全被包型や部分的被包型などの症例に出現する傾向がみられた. 誤判定の原因としては細胞採取量が少ないこと, 核内封入体や核溝がみられなかったこと, あるいはそれらの数が少なかったことなどがあげられた.

Rapid diagnosis of the nervous system tumors - Crush cytology method.

Sakae Hata; Shinobu Yamamoto; Takashi Fukuya; Kenya Hiura; Chotatsu Tsukayama; Teruo Shirabe; Sadaaki Nakagawa

1971年から1982年までの12年間に経験した脳神経腫瘍のうち, crush細胞診を併用して診断された原発性脳腫瘍74例について検討した。Crush細胞診は, 術中迅速診断を求めて送られてくる外科標本から簡単に細胞診用の標本が作製でき, 凍結標本に比べて短時間で明瞭な細胞像が得られるため, 脳神経系腫瘍の診断に凍結切片標本と併用して用いることが有用であると伴断した.
