Abstract

Three cases of ovarian teratoma in bovine were diagnosed at first time in southern of Iraq. Through investigation of ovaries in 120 cows. Showed macroscopical description of ovaries lesions which were bilateral malignant tumors on external surface for each ovary (left and right).The specific characteristics of this tumor was presence of hair embedded within texture of lesion which represented to embryo remnants, As well as, the study revealed a histological exploration of tumor that. Granulosa cells under go different stages of mitotic divisions were noted during the histological study. Also tumor tissues represented as keratinized squamous epithelial tissue, contained skin adenxal structures such as hair follicle. The closed similarity between teratoma and epidermoid cysts results in misdiagnosis between them. The present study revealed that teratoma is more frequently incidence to the cattle than other demotic animal in addition this tumor had similar features to the teratoma in women.

تم تشخيص ثلاث حالات لورم في المبيض للابقار في جنوب العراق . من خلال التحري والفحص النسيجي ل 120 مبيض العائدة لاناث الابقار من مجزرة الناصرية . اظهر الفحص العياني وجود كتل ورمية فوامها شبه سائل تشغل ثلث حجم المبيض . حيث سجلت الدراسة حدوث هذه االاصابة لاول مرة في العراق والتي اعتبرت من الاصابات النادرة في الحيوانات على شكل الأورام الخبيثة .كذلك بينت ظهور الورم بشكل بشكل ثنائي على السطح الخارجي لكل المبيض (اليسار واليمين) .الخصائص المحددة لهذا الورم كان وجود الشعر جزءا لا يتجزأ من نسيج من الآفة التي تمثل بقايا الجنين، فضلا عن الدراسة كشف من خلال الفحص النسيجي لهذا الورم عدة خصائص يتميزبها. حيث لوحظت مراحل مختلفة من الانقسامات الانقسامية خخلايا جرانولوسا تحت المجهر الضوئي التي كانت تمثل الأنسجة الورمية كذلك الأنسجة الظهارية الحرشفية الكيراتينية ضهرت بشكل متزايد وانويتها تعاني من انقسامات اختزالية.علاوة على ذلك تضمنت هياكل الجلد الاثرية مثل بصيلات الشعر. ويؤدي التشابه المغلق بين الورم المسخي والخراجات البشروية إلى تشخيص خاطئ بينهما. وكشفت الدراسة الحالية أن الورم المسخي فد يصيب كثير من الأحيان الإصابة للحيوانت المستانسة ومنها الماشية بالإضافة إلى هذا الورم كانت له ميزات مماثلة إلى الورم مسخي الشائع في النساء

Abstract

ABSTRACT:BACKGROUND:Sacrococcygeal teratoma is the most common tumor in the newborn.. Approximately 90% of sacrococcygeal teratomas excised during the neonatal period are benign. The risk of malignancy increases in lesions removed after 6 months of age. OBJECTIVE::To discuss the management of newborns with sacrococcygeal teratomas and the importance of early surgical intervention in avoiding the risk of malignant transformation.PATIENTS AND METHODS: 11 neonates with sacrococcygeal teratomas were managed during the period from April 2008 through April 2013. In all cases, age, sex, mode of delivery, details of surgery, extent of resection, macroscopic tumor appearance, tumor histology, Altman classification and postoperative morbidity and mortality were all documented and analyzed. A two years follow up plan was designed to assess any complication and tumor recurrence.RESULTS: Classical sacrococcygeal approach was performed in all of the patients operated upon and complete excision of the tumor along with the coccyx was possible in all cases. According to the Altman classification 8 (72.7%) of the tumors were of type I. Macroscopically, 7(63.6%) tumors were mixed,. Histopathological examination of the excised tumors revealed the diagnosis of benign mature teratoma in all cases. All of the newborns survived with the exception of one patient with a giant sacrococcygeal mass who died because of heart failure . No tumor recurrence was documented in all of the patients operated on.CONCLUSION:Early detection including antenatal diagnosis is essential to define fetuses with poor prognostic signs and deciding the appropriate mode of delivery, and in some centers even fetal intervention. Early excision of these tumors during the neonatal period is essential to avoid the risk of malignant transformation.

Abstract

Background: Sacrococcygeal teratoma is seen in 1 in every 35000 live births, and is the most common tumor presenting in newborn and children but also reported in adults.(1)Sacrococcygeal teratoma are the most common type of germ cell tumors (both benign and malignant) diagnosed in neonates , infants and children younger than 4 years.(2Case report: A 2 years old male child presented with a visible lump or mass under the skin at the top of the buttocks crease after falling on the ground on his buttocks, and the parents give a history that the child had a constipation since birth.The case was diagnosed as endodermal sinus tumor with yolk sac elements on the bases of clinical examination, ultrasonography, CTscan and fine-needle aspiration cytology..After diagnoses patient referred to the oncologist for multi-drug chemotherapy and surgical removal by the pediatric surgeon after shrinkage of the tumor mass.Conclusion: Infants and young children present with a palpable mass in the sacropelvic region have a greater likelihood of being malignant.

Abstract

Struma ovarii is a highly specialized form of ovarian teratoma, characterized by the presence- entirely or predominantly- of mature thyroid tissue. Its most important complications, although rare, are malignant transformation and thyrotoxicosis. In the present 'case report' we describe a case of a 25 year old married woman that seeks medical advice for recurrent lower abdominal discomfort. The diagnosis of complex ovarian cyst confirmed by ultrasound examination of the abdomen, the operative findings were multilocular ovarian cyst treated by oophrectomy. The histological examination demonstrated typical elements of mature thyroid tissue that confirmed the diagnosis of struma ovarii.Keywords: ovarian teratoma, struma ovarii, thyroid tissue

ستروما المبيض هو نوع خاص جدا من مثاني المبيض(تراتوما) ويتميز بأحتوائه كليا او جزئيا على نسيج الغده الدرقيه. ومن مضاعفاته المهمه ولو كانت نادره هي تحوله الى ورم خبيث او قد يؤدي الى فرط افراز الغده الدرقيه. في هذه الحاله نصف امرأه متزوجه عمرها 25 سنه كانت تعاني من الم متكررفي اسفل البطن وتم تشخيص كيس معقد للمبيض بواسطة فحص البطن بجهاز الامواج الصوتيه (السونار).وكانت نتيجة العمليه كيس معقد للمبيض واجري لها عملية استئصال المبيض ومن خلال الفحص النسيجي تبين وجود نسيج ناضج للغده الدرقيه والذي اثبت تشخيص ستروما المبيض.مفتاح الكلمات: مثاني المبيض, ستروما المبيض, نسيج الدرقيه
