S-100 protein in glands within decidua and cervical glands during early pregnancy

Yasuhiro Nakamura; Yuko Moritsuka; Yoshitaka Ohta; Sonoe Itoh; Akiko Haratake; Masayoshi Kage

Strong immunoreactivity with polyclonal S-100 protein antisera and monoclonal S-100 alpha subunit antiserum was found in glandular cells of the decidua basalis and cervical polyps during early pregnancy. Immunoreactive S-100 protein was negative in glandular cells of the endometrium and cervix of nonpregnant women. It was also negative in endometrial hyperplasia and endometrial carcinoma. While the function of S-100 protein is not known, a relationship between humoral factors related to pregnancy and expression of S-100 protein gene is suggested by the results of this study.

背景:肝穿刺吸引細胞診にてカルチノイドを疑い, 剖検にて肝原発カルチノイドと診断した1例を経験したので報告する.症例:37歳, 男性. 右胸腹部痛を訴え, 当院を受診. 超音波検査にて肝膿瘍を疑い, エコー・ガイド下にて経皮経肝的ドレナージならびに抗生剤投与を施行した. ドレナージにより検出された内容物は茶褐色液状様で, 細胞診検索では軽度の炎症所見と壊死物質を多数認めるのみで悪性所見はみられなかった. 造影CT画像検査では, 肝内全体に数mmから約90mmのcystic lesionを多数認めるなかに, S3とS6の部位では, 内部不均一に造影されるsolid massが観察された. CT画像診断は, cystic & solid mass of the liverであった. 精査目的にて, エコー・ガイド下に, S6の部位より肝穿刺吸引細胞診を施行した. 細胞形態学的に細胞採取量は豊富で腫瘍細胞は細胞間結合の粗な平面的集団として認められた. 個々の細胞は比較的均一だが, 全般にN/C比が高く, 一部にロゼット様配列を認めた. 細胞質はライトグリーン淡染性で核クロマチンはsalt and pepPer状を呈することから, まれではあるがカルチノイド腫瘍を疑い, 脱Papanicolaou染色標本による免疫染色を施行した. クロモグラニンは弱陽性, シナプトフィジン, NSEは陽性, CEAは陰性であった. 肝生検病理組織診では, カルチノイドを含む神経内分泌腫瘍と診断された. 肝実質のほとんどは腫瘤に置換されており外科的治療は困難と考えられ, 化学療法ならびにTAE (肝動脈塞栓術) が施行されたが, 効果なく18ヵ月後に永眠となった. 剖検による肝は著明に腫大し, 大小の多発性嚢胞性腫瘤を認めた. 腫瘍部の組織像は円形から楕円形の腫瘍細胞が充実性に, また一部でロゼット様配列を示していた. 他臓器に病変がみられないことから肝原発カルチノイドと診断された.

Growth Factors in Infant Germinal Matrix: Relationship to Extracellular Matrix and Cell Adhesion Molecules

Yasuhiro Nakamura; Munehiko Yamamoto; Sonoe Itoh; Akiko Haratake; Yuko Nakano; Takeo Hashimoto

We examined the expression of selected growth factors, growth factor receptors, elements of extracellular matrix and cell adhesion molecules in the germinal matrix layer (GML) utilizing immunohistochemistry and reverse transcriptase polymerase chain reaction. At autopsy brain samples from 10 neonatal infants were used. Epidermal growth factor receptor (EGFR) was significantly expressed in the matrix cells. While transforming growth factor α and heparin-binding epidermal growth factor-like growth factor were found in the matrix cells or vascular wall as ligands, epidermal growth factor was not expressed. EGFR and its ligands are thought to be important factors for the maintenance of the matrix cells and cell-to-cell interactions. Insulin like growth factor I, its receptor Iβ and tenascin were found in the stroma of the GML and periventricular region. Vascular endothelial growth factor and receptor Flk-1, laminin A and B2, fibronectin, collagen type IV and integrins such as β3, α5β1 and αVβ3 were found mainly in or around the vascular wall indicating their important roles for vascularization. Transforming growth factor β2 and its receptor II were expressed in the matrix cells and/or vascular wall suggesting a role in proliferation and/or regression of the vasculature. CD44 and Thy-1 were also expressed in the matrix cells.

背景:小児肝に発生したまれな平滑筋肉腫の1例を経験したので, 術中捺印細胞診像を中心に病理所見, 免疫所見, 電顕所見を加え報告する.症例:15歳の男児で上腹部痛を主訴に来院.腫瘍は肝左葉に11cm×12cmの結節性病変としてみられ, 腫瘍割面は灰白色充実性で一部に出血像が認められた.術中捺印標本上の腫瘍細胞量は豊富で, それら腫瘍細胞は比較的異型に乏しい紡錘形細胞の束状出現を主体に一部散在性に異型の強い巨細胞や核内封入体形成細胞が混在して認められた.核分裂像, 壊死像はほとんど認められなかった.また肝周囲のリンパ節に転移が認められ, その細胞像は肝のそれと全く同様の所見を呈した.免疫化学的染色において腫瘍細胞はVimentin, Desmin, α-smooth muscle actin (α-SMA) に陽性を示し, なかでもα-SMAは紡錘形細胞に選択的陽性を示した.組織学的には好酸性の紡錘形細胞質を有する腫瘍細胞が交錯する像がみられた.なお, 周囲には多数のリンパ球の浸潤があり, ほとんどがTcel1マーカーに陽性を示した.電顕ではdensebodyと基底膜様物質の存在を認めた.結語:総合的所見より平滑筋肉腫と診断されたが, 術中捺印細胞像でも比較的特徴的な細胞像を呈しており, 推定可能な症例であったと考える.
