TEXTUS MUSCULARIS (JARINGAN OTOT)1. Leiomyoma of the uterus

Clinical informationA 34 year old female patient was admitted to the hospital due to incidental vaginal bleeding, some time as spotting, meno or metrorrhagy alternatingly, and by physical and USG enlargement of the uterus was found. The patient was histerectomized and the specimen was sent to pathology lab.Gross examinationA swelling uterus was received and a well demarcated solid white mass was found intramural, 6 cm in diameter, fleshy.Microscopic pictureThe mesenchymal tumor composed of interlacing bundles of smooth muscle separated by a grater or lesser amount of well vascularized connective tissue. In some areas there are hyalin degeneration (the interlacing bundles of smooth muscles is also called perpendicular crossing). The tumor cells are spindle shaped with elongated nuclei, without any cells atypia and mitoses.

1. Leiomyoma rahimInformasi klinisSeorang pasien wanita 34 tahun dirawat di rumah sakit karena pendarahan vagina insidental, beberapa waktu sebagai bercak, meno atau metrorrhagy alternatingly, dan dengan px fisik dan USG pembesaran rahim ditemukan. Pasien histerectomized dan spesimen itu dikirim ke laboratorium patologi.Pemeriksaan grossRahim yang telah diterima dan pembengkakan massa juga batas-batasnya putih solid ditemukan intramural, 6 cm, berdaging.Gambar mikroskopisMesenchymal tumor terdiri dari bundel jalinan otot polos dipisahkan oleh parutan atau jumlah yang lebih rendah dari jaringan ikat vascularized baik. Di beberapa daerah ada degenerasi hyalin (interlace bundel otot polos juga disebut persimpangan tegak lurus). Sel-sel tumor berbentuk gelendong memanjang dengan inti, tanpa atypia sel dan mitosis.

2. LipomaClinical informationA 32 year old male patient because of swelling of his back. Palpation of the mass revealed a soft and mobile mass. The mass was excised and sent to the pathology lab.Gross examinationA soft and encapsulated mass was received, 8 cm in diameter, soft and the cut surface of the mass is yellowish.Microscopic pictureThe mesenchymal tumor composed of mature adipose tissue surrounded by complete thin fibrous tissue. There is no any cellular atypia and mitoses.

2. LipomaInformasi klinisSeorang pasien laki-laki 32 tahun karena pembengkakan punggungnya. Palpasi massa mengungkapkan massa lunak dan mobile. Massa itu dipotong dan dikirim ke laboratorium patologi.Pemeriksaan grossMassa lembut dan dikemas diterima, 8 cm diameter, lembut dan permukaan memotong massa yang kekuningan.Gambar mikroskopisMesenchymal tumor terdiri dari jaringan adiposa dewasa dikelilingi oleh jaringan fibrosa tipis yang lengkap. Tidak ada apa pun atypia selular dan mitosis.

4. Capillary hemangiomaClinical informationA 3 month male baby was admitted to the hospital due to the red small elevated on the skin of the right upper arm.

Page 2: mesencim 2

Gross examinationA piece of skin with an intense crimson color elevated nodule was received.Microscopic pictureThe tumor is made up of hyperplasia of small vessels (capillary), and most of the capillaries were engorged with erithrocytes. The capillaries are lined by proliferation of the monomorphic endothelial cells.

4. Hemangioma kapilerInformasi klinisSeorang bayi laki-laki 3 bulan dirawat di rumah sakit karena ditinggikan merah kecil pada kulit lengan kanan atas.Pemeriksaan grossSepotong kulit dengan warna intens nodul merah ditinggikan diterima.Gambar mikroskopisTumor terdiri dari hiperplasia pembuluh kecil (kapiler), dan sebagian dari kapiler yang membesar dengan erithrocytes. Kapiler dibatasi oleh proliferasi sel endotel monomorfik.

7. LeiomyosarcomaClinical informationA 65 year old female patient was admitted to the hospital for swelling of her lower abdomen. About 30 years ago she had history of incidental vaginal bleeding, some time as spotting, meno or metrorrhagy alternatingly, and she underwent enucleation operation of the uterine mass. By physical and USG enlargement of the uterus was found. The patient underwent hysterectomy and the specimen was sent to pathology lab.Gross examinationGrossly the specimen showed a large, solid, soft or fleshy poorly circumscribed mass of the uterus, with necrotic and hemorrhagic areas.Microscopic pictureThis is a hypercellular tumor with necrotic and hemorrhagic area. Tumor cells infiltration into surrounding myometrium. The tumor is composed of oval to spindle, atypical cells, with hyperchromatic nuclei and some multinucleated cells. There are more than 10 mitotic cells per 10 high-fields view.

7. LeiomyosarcomaInformasi klinisSeorang pasien wanita berusia 65 tahun dibawa ke rumah sakit untuk pembengkakan perut bawahnya. Sekitar 30 tahun yang lalu ia telah riwayat perdarahan vagina insidental, beberapa waktu sebagai bercak, meno atau metrorrhagy alternatingly, dan ia menjalani operasi enukleasi dari massa uterus. Dengan fisik dan USG pembesaran rahim ditemukan. Pasien menjalani histerektomi dan spesimen dikirim ke laboratorium patologi.Pemeriksaan grossTerlalu spesimen menunjukkan massa buruk terbatas yang besar, padat, berdaging lunak atau rahim, dengan area nekrotik dan perdarahan.Gambar mikroskopisIni adalah tumor hypercellular dengan area nekrotik dan perdarahan. Sel tumor infiltrasi ke sekitar miometrium. Tumor terdiri dari oval untuk gelendong, sel-sel atipikal, dengan inti hyperchromatic dan beberapa sel multinuklear. Ada sel mitosis lebih dari 10 per 10 tinggi-bidang tampilan.

8. LiposarcomaClinical informationA 75 year old male was admitted tot the hospital because of the diffuse swelling of the right thigh. She underwent operation and the specimen was sent to pathology lab.Gross examinationLarge and soft mass of the thigh was received, no capsule was identified. The mass has bright yellow appearance mimicking lipoma and some necrotic areas were found.

Microscopic pictureThis is a hypercellular tumor, composed of lipoblast with many mitotic cells. This appears as mononuclear or multinucleated cells with one or more cytoplasmic vacuoles that contain fat. The nucleus could be pushed aside by a single large vacuole, resulting in a signet ring configuration. Some cells with the remain centrally nuclei, but exhibit small indentations by multiple small vacuoles.

8. LiposarcomaInformasi klinisSeorang pria berusia 75 tahun dirawat di rumah sakit tot karena berdifusi pembengkakan paha kanan. Dia menjalani operasi dan spesimen dikirim ke laboratorium patologi.Pemeriksaan grossMassa besar dan lembut paha diterima, tidak ada kapsul diidentifikasi. Massa telah terang meniru penampilan lipoma kuning dan beberapa daerah nekrotik ditemukan.Gambar mikroskopisIni adalah tumor hypercellular, terdiri dari lipoblast dengan sel mitosis banyak. Ini muncul sel sebagai mononuklear atau multinuklear dengan satu atau lebih vakuola sitoplasma yang mengandung lemak. Inti bisa didorong ke samping oleh sebuah vakuola besar tunggal, sehingga dalam konfigurasi cincin. Beberapa sel dengan inti tetap terpusat, tetapi menunjukkan lekukan kecil dengan vakuola kecil beberapa.

MESENCHYMAL TUMORS II14. Rhabdomyosarcoma

Clinical informationA 75 year old male suffered from swelling of the left thigh, no pain was identified. The man underwent operation and the specimen was sent to pathology lab.Gross examinationA part of muscle with a soft and fleshy, beef red-brown coloured mass was received by pathology lab. The mass of 10 cm in diameter is poorly circumscribed.Microscopic pictureThis tumor is hypercellular, composed of bizarre small and undifferentiated rhabdomyoblast cells, with some tumor giant cells. Rhabdomyoblast cells are large cells with dark or vesicular nuclei and abundant acidophilic cytoplasm (cross striations may not seen). Many mitoses and necroses areas can be found.

14. RhabdomyosarcomaInformasi klinisSeorang pria berusia 75 tahun menderita pembengkakan pada paha kiri, tidak sakit diidentifikasi. Pria itu menjalani operasi dan spesimen dikirim ke laboratorium patologi.Pemeriksaan grossSebuah bagian dari otot dengan massa, lembut dan berdaging merah-coklat daging sapi berwarna diterima oleh patologi laboratorium. Massa dari 10 cm diameter kurang dibatasi.Gambar mikroskopisTumor ini hypercellular, terdiri dari sel aneh rhabdomyoblast kecil dan dibeda-bedakan, dengan beberapa sel raksasa tumor. Rhabdomyoblast sel adalah sel besar dengan inti gelap atau vesikuler dan sitoplasma acidophilic berlimpah (striations lintas mungkin tidak terlihat). Banyak mitosis dan daerah nekrosis dapat ditemukan.

A large mass covered with skin was received, and from cut surface a poorly bordered solid mass were seen. Capsule can not be identified and some necrotic area are quite obvious.Microscopic pictureThis is a hypercellular tumor, composed of atypical and polymorphic Histiocytic and fibroblastic cells in appearance with fascicular and storiform pattern. The cells nuclei are hyperchromatic with many abnormal mitoses and bizarre tumor giant cells.
