Uterine rescue in high-risk gestational trophoblastic neoplasia treated with ema-co by uterine arteries embolization due to arteriovenous malformations / Resgate uterino em neoplasia trofoblástica gestacional de alto risco tratada com EMA-CO por embolização de artérias uterinas devido a malformações arteriovenosas

Abstract Complete hydatidiform mole (CHM) is a rare type of pregnancy, in which 15 to 20% of the cases may develop into gestational trophoblastic neoplasia (GTN). The diagnostic of GTN must be done as early as possible through weekly surveillance of serum hCG after uterine evacuation.We report the case of 23-year-old primigravida, with CHM but without surveillance of hCG after uterine evacuation. Two months later, the patient presented to the emergency with vaginal bleeding and was referred to the Centro de Doenças Trofoblásticas do Hospital São Paulo. She was diagnosed with high risk GTN stage/score III:7 as per The International Federation of Gynecology and Obstetrics/World Health Organization (FIGO/WHO). The sonographic examination revealed enlarged uterus with a heterogeneous mass constituted of multiple large vessels invading and causing disarrangement of the myometrium. The patient evolved with progressive worsening of vaginal bleeding after chemotherapy with etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMA-CO) regimen. She underwent blood transfusion and embolization of uterine arteries due to severe vaginal hemorrhage episodes, with complete control of bleeding. The hCG reached a negative value after the third cycle, and there was a complete regression of the anomalous vascularization of the uterus as well as full recovery of the uterine anatomy. The treatment in a reference center was essential for the appropriate management, especially regarding the uterine arteries embolization trough percutaneous femoral

Resumo Mola hidatiforme completa (MHC) é um tipo raro de gravidez, na qual 15 a 20% dos casos podem desenvolver neoplasia trofoblástica gestacional (NTG). O diagnóstico de NTG deve ser feito o mais cedo possível, pelo monitoramento semanal do hCG sérico após esvaziamento uterino. Relatamos o caso de uma paciente primigesta, de 23 anos de idade, com MHC, sem vigilância de hCG após esvaziamento uterino. Dois meses depois, a paciente compareceu na emergência com sangramento vaginal, sendo encaminhada ao Centro de Doenças Trofoblásticas do Hospital São Paulo, onde foi diagnosticada com NTG de alto risco, estádio e score de risco III:7 de acordo com a The International Federation of Gynecology and Obstetrics/Organização Mundial de Saúde (FIGO/OMS). O exame ultrassonográfico revelou útero aumentado com uma massa heterogênea constituída pormúltiplos vasos volumosos invadindo e desestruturando o miométrio. A paciente evoluiu com piora progressiva do sangramento vaginal após quimioterapia com o regime etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMA-CO). Ela foi submetida a transfusão de sangue e embolização das artérias uterinas devido aos episódios graves de hemorragia vaginal, com completo controle do sangramento. O hCG atingiu valor negativo após o terceiro ciclo, havendo regressão completa da vascularização uterina anômala, assim como recuperação da anatomia uterina. O tratamento em um centro de referência permitiu o manejo adequado, principalmente no que se refere à embolização das artérias uterinas através da punção percutânea da artéria femoral, que foi crucial para evitar a histerectomia, permitindo a cura da NTG e a manutenção da vida reprodutiva.

Embryonal Rhabdomyosarcoma Arising from a Mediastinal Teratoma: An Unusual Case Report

We report an unusual case of 9.5-cm-sized embryonal rhabdomyosarcoma arose from a mediastinal mature teratoma in a 46-yr-old man. A man presented with chest trauma as a result of an accident at 10 September 2011. On chest X-ray, an anterior mediastinal mass was detected. To obtain further information, chest computed tomography (CT) with contrast enhancement was performed, revealing an anterior mediastinal mass. Complete surgical excision was performed and entire specimen was evaluated. Pathologic diagnosis was embryonal rhabdomyosarcoma arising in mature cystic teratoma. After surgical excision, two cycles of dactinomycin-based chemotherapy were performed. Lung metastasis was detected on follow up CT in September 2012, and wedge resection was performed. Pathological finding of the lung lesion showed same feature with that of primary rhabdomyosarcoma.

Gestational choriocarcinoma presenting as hemothorax.

Choriocarcinoma include a spectrum of chorionic neoplasms that may be gestational or non-gestational. By virtue of their high vascularity and affinity of trophoblast for blood vessels, metastases often occur early, and the most common site of such metastases is the lung. Metastatic pleural effusions from choriocarcinoma are infrequent. Pleural seeding usually results from extension of a sub-pleural peripheral nodule. We describe a case of gestational choriocarcinoma whose clinical presentation was medical like hemothorax as in our case rather than gynecologic.

Primary non-gestational uterine cervical choriocarcinoma with metaplastic transformation from squamous cells.

BACKGROUND: Primary non-gestational uterine cervical choriocarcinoma is very unusual and although it has been hypothesized that it can arise by metaplastic transformation of cervical epithelium, solid evidence has been lacking. CASE: Primary non-gestational uterine cervical choriocarcinoma was diagnosed in a 47-year-old, woman undergoing tubal resection 17 years previously. A histologically- and immunohistochemically-confirmed, non-gestational cervical choriocarcinoma could be diagnosed in which there was metaplastic transformation from squamous cells . The patient underwent 5 courses of an actinomycin-D chemotherapeutic regimen and radical hysterectomy with bilateral pelvic lymphadenectomy. CONCLUSION: Primary non-gestational uterine cervical choriocarcinoma may indeed arise from metaplastic transformation of epithelial tissue.

Orbital rhabdomyosarcoma: a case series.

Orbital rhabdomyosarcoma is the most common orbital malignancy of childhood with the common presentation of rapidly evolving unilateral proptosis. We studied six patients who were diagnosed and treated for rhabdomyosarcoma between January 1999 and June 2004. The age of the patients ranged from 4 to 29 years. Four patients presented with acute onset proptosis associated with signs of inflammation, mimicking orbital cellulitis. One patient presented with lid mass. Another patient presented with a soft, blind eye that was pushed superotemporally by a large inflammed, vascularised mass. Embryonal rhabdomyosarcoma was the commonest histopathological type in our series found in five patients. One patient was completely cured with chemotherapy alone whereas two patients were treated with a combination of chemotherapy and radiotherapy. Three patients in our series required exenteration.

A Case of the Treatment in an Adult with Hepatic Undifferentiated (Embryonal) Sarcoma / 대한간학회지

Undifferentiated embryonal sarcoma is a rare primary malignant neoplasm of the liver. Undifferentiated sarcoma of the liver in adult is an uncommon hepatic tumor of mesenchymal origin, generally considered an aggressive neoplasm with an unfavorable prognosis. We present a case of undifferentiated sarcoma in a 61-year-old woman. CT scan demonstrated a large heterogenous, exophytic growing hepatic mass in the right lobe with pulmonary metastatic nodules. US guided liver biopsy was done and pathological findings of the liver specimen revealed that isolated or grouped round pleomorphic cells and spindle to stellate cells were present. Immunohistochemical stain showed that tumor cells expressed positivity for vimentin and partially positivity or negativity for cytokeratin. She was diagnosed as having undifferentiated sarcoma of the liver. She received seven courses of VAIA chemotherapy by CWS protocols. Chemotherapy was efficacious and the size of the tumor decreased considerably after the treatment. No tumor recurrence for 12 months is noted.

Coriocarcinoma de ovario / Choriocarcinoma of the ovary

Se presentó un caso de coriocarcinoma ovárico en una mujer de 24 años de edad sin antecedentes de gestaciones. Clínicamente la enfermedad debutó con un cuadro respiratorio y radilógico con características de tuberculosis pulmonar. Por la presencia de una masa tumoral del anexo derecho la paciente fue operada encontrándose un tumor de ovario diagnosticado histológicamente como coriocarcinoma, con implantes neoplásicos en mesosalpinx y pared del cuello uterino. La paciente recibió tratamiento quimioterápico y sobrevivió cuatro años. Se discute la posibilidad de que la neoplasia haya sido primaria o metastásica a ovario
