Abstract

Abstract: Medullary carcinoma of the thyroid is a rare thyroid cancer that is derived from parafollicular cells (C cells) of the thyroid gland. It only accounts for approximately 5% of all thyroid neoplasms. We reported a case of medullary carcinoma of the thyroid in a 44-year-old woman with tetraparesis, hypokalemia, and diarrhea. She also had two lumps in the anterior and left part of her neck. Medullary carcinoma was diagnosed by using fine needle aspiration biopsy (FNAB) of both lumps. The smears showed rich cellularity of variated cells from small and large round cells, spindles, and with plasmacitoid and hyperchromatic nuclei. These cells were dispersed and clustered. The background of the amyloid mass (amorphous material) showed as magenta masses with an MGG stain and orange masses with a Pap’s stain. The amyloid material is one of the diagnostic features of medullary carcinoma of the thyroid. The diagnosis can be confirmed with the patient’s blood calcitonin serum. In this case, we already performed an immunocytochemical stain of calcitonin but it was negative. Altough the calcitonin stain was negative, this medullary carcinoma of the thyroid could not be excluded because the patient still showed clinical symptoms due to hypercalcitoninemia. Some studies reported that the immunoreactive reaction of the calcitonin were more than 25% of the tumor cells. Keywords: medullary carcinoma thyroid, amyloid, fine needle aspiration biopsy.  Abstrak: Karsinoma meduler tiroid adalah keganasan kelenjar tiroid yang berasal dari sel-sel parafolikuler (sel C) kelenjar tiroid. Tumor jenis ini jarang ditemukan, hanya sekitar 5 % dari semua kanker tiroid. Kami melaporkan kasus seorang wanita berusia 44 tahun dengan gejala klinis tetraparesa, hipokalemia, diare, dan disertai adanya dua benjolan sebesar bola pingpong pada leher bagian anterior dan lateral kiri. Diagnosis karsinoma meduler tiroid ditegakkan melalui pemeriksaan biopsi aspirasi jarum halus pada kedua benjolan tersebut. Hasil pemeriksaan menunjukkan hapusan seluler terdiri dari sel-sel yang bervariasi: berbentuk bulat dengan ukuran kecil dan besar, spindel, dan plasmasitoid; inti  sel tampak hiperkromatik, tersebar atau berkelompok. Latar belakang terlihat bahan amorf amiloid berwarna merah magenta pada pengecatan MGG, dan berwarna jingga pada pengecatan Papanicolaou. Bahan amiloid merupakan salah satu tanda diagnostik untuk karsinoma meduler tiroid. Untuk kepastian diagnosis dapat dikonfirmasi dengan pemeriksaan kadar kalsitonin serum. Pada kasus ini  pemeriksaan imunositokimia untuk kalsitonin memberi hasil negatif, namun belum dapat menyingkirkan diagnosis karsinoma meduler tiroid.  Beberapa peneliti melaporkan imunoreaktif kalsitonin untuk karsinoma meduler tiroid 25% atau lebih pada sel-sel tumor tersebut. Kata kunci: karsinoma meduler tiroid, amiloid, biopsi aspirasi jarum halus.

Abstract

Abstract: Androgenic-anabolic steroids (AAS) are synthetic derivatives of the male hormone endogenous testosterone that stimulates anabolic (protein synthesis) and androgenic effects (masculinization). Long-term usage of AAS can result in liver damage. However, physiological concentrations of testosterone can stimulate protein synthesis which lead to an increase in muscle size, body mass, and endurance. This study aimed to determine the histopathology of liver and skeletal muscles of wistar rats that were given low dose and high dose injection of AAS. Subjects were 21 wistar rats divided into 7 groups. Group A was given standard pellets for 56 days (negative control), terminated on days 29,43, and 57. Group B was treated with low-dose AAS injection and standard pellets for 28 days, terminated on day 29. Group C was treated with low-dose AAS injection and standard pellets for 42 days, terminated on day 43. Group D was treated with low-dose AAS injection and standard pellets for 56 days, terminated on day 57. Group E was treated with high-dose AAS injection and standard pellets for 28 days, terminated on day 29. Group F was treated with high-dose AAS injection and standard pellets for 42 days, terminated on day 43. Group G was treated with high-dose AAS injection and standard pellets for 56 days, terminated on day 57. The results showed that the histopathology of liver and muscles in group A was still normal. In group B, the architecture of liver was still normal with a few inflammatory cells around the Kiernan triangle while in muscle the ratio of myofibril diameter was 1.28:1. In group C and group D, there were widening of the hepatic artery, bile duct, and portal vein containing blood fibrin, and inflammatory cells around the Kiernan triangle. The ratio of myofibril diameter was 1.43:1 in group C and 2.14:1 in group D. In group E, F and G, there were micro-vesicular fatty cells in the peripheral part of the liver meanwhile the myofibril diameter ratio of the muscles in group E was 1.43:1, group F 2.1:1, and group G 2.28:1. Conclusion: Administration of AAS injection of low dose and high dose for less than 4 weeks could result in inflammation, dilation of the portal vein, hepatic artery and bile duct meanwhile administration of AAS for over 4 weeks could ressult in focal fatty liver (steatosis). The administration of AAS injection of low dose and high dose for 4,6 and 8 weeks reslutid in enlargement of skeletal muscle (muscle hypertrophy).Keywords: androgenic-anabolic steroids, liver, skeletal muscleAbstrak: Anabolik Androgenik Steroid (AAS) adalah derivat sintetis dari hormon sex testosteron endogen pria, yang merangsang efek anabolik (sintesis protein) dan androgenik (maskulinisasi).

Abstract

Abstract: Ovarian teratoma is a germinal cell tumor derived from fetal yolk sac germinal cells. This tumor can occur in gonads and extragonads. Its frequency is around 25%, which is less than 40% for sacrococygeal teratoma. According to WHO’s classification, ovarian teratoma is divided into three groups: immature, mature, and monodermal teratoma. Among these groups, the dermoid cyst has the highest incidence of all ovarian tumors (26-44%); and 85% of these have an age range of 20-56 years. But the other kinds of teratoma are rarely found. Clinicopathological aspects of teratomas are very unique, since these tumors develop from totipotential germinal cells. If these germinal cells differentiate along the embryonic line, then the tumor will consist of three components: ectoderm, endoderm, and mesoderm. As a result of this, the tumors show a variety of morphologies. A monodermal teratoma, e.g. an ovarian struma or a carcinoid tumor, contains only one component. Clinically, ovarian teratoma manifests itself as a mass in the ovarium, with accompanying pain, abdominal distention, or emesis. However, mostly there is no palpable mass in the abdomen, and clinical signs and symptoms manifest themselves later. The tumor can be detected earlier in case of an ovarian torsion. Key words: teratoma, mature, immature, monodermal.   Abstrak: Teratoma ovarium merupakan tumor sel germinal yang berasal dari sel-sel germinal yolk sac fetus. Tumor ini dapat ditemukan pada gonad dan ekstragonad. Frekuensi teratoma ovarium sekitar 25%, sesudah teratoma sakrokoksigeal 40%. Menurut klasifikasi  WHO teratoma ovarium dibagi atas tiga kelompok: teratoma imatur, matur, dan monodermal. Di antara ketiga jenis teratoma ovarium ini, kista dermoid  mempunyai insiden tertinggi (26%-44%) dari semua tumor ovarium; dan 85% penderita berusia antara 20-56 tahun. Jenis lain sangat jarang ditemukan. Aspek klinikopatologik teratoma tergolong unik karena secara  patogenesis teratoma berkembang dari sel-sel germinal totipotensial. Bila sel-sel germinal berdiferensiasi sepanjang garis embrionik, maka tumor biasanya terdiri atas tiga komponen, yaitu ektoderm, endoderm, dan mesoderm, dengan  morfologi yang berbeda-beda. Teratoma monodermal (struma ovarium dan tumor karsinoid) terdiri dari satu komponen jaringan saja. Secara klinis  teratoma ovarium ditandai oleh adanya massa pada ovarium, disertai nyeri, distensi abdomen, atau emesis.  Walaupun demikian, umumnya jarang teraba massa dan gejala klinis timbul lambat. Diagnosis penyakit dapat ditegakkan lebih dini bila terjadi torsi ovarium. Kata kunci: teratoma, matur, imatur, monodermal.
