Carcinoma de salpinge: caso reporte y revisión bibliográfica / Salpinge carcinoma: case report and literature review

El cáncer primario de salpinge uterina es una neoplasia maligna rara del aparato genital femenino, corresponde al 0.1 a 1.8% de las neoplasias malignas ginecológicas. Se presenta sobre todo en pacientes menopáusicas o post menopáusicas, con mayor incidencia entre los 55-65 años de edad. Presentamos el caso de una paciente de 45 años de edad con el diagnostico de carcinoma primario de salpinge siendo que la paciente acude a consulta por dolor abdominal y presencia de flujo vaginal, con reporte ecográfico de masa anexial derecha, es ingresada a cirugía con el diagnóstico pre-operatorio de "tumor de ovario derecho", se realiza estudio trans-operatorio mismo que descarta lesión en ovario y postula lesión neoplásica primaria de salpinge , llegando al diagnóstico definitivo por histopatología e inmunohistoquimica de carcinoma seroso de alto grado, afecta capa muscular sin rebasarla. Asociado a focos de TIC (carcinoma intratubario). En ovario se evidenció: ocarcinoma seroso de alto grado metástasico de salpinge.

The primary fallopian tube cancer is a rare malignancy of the female genital tract, corresponds to 0.1 to 1.8% of gynecologic malignancies. It occurs mainly in menopausal or post-menopausal patients with the highest incidence among 55-65 years old. We report the case of a patient of 45 years with the diagnosis primary carcinoma of the fallopian tube being that the patient comes in for abdominal pain and presence of vaginal discharge, with sono-graphic report right adnexal mass is entered surgery with the diagnosis pre-operatorio of "right ovarian tumor," trans-operative same rule ovary injury study is conducted and postulates salpinge primary neoplastic lesion, reaching definitive diagnosis by histopathology and immunohistochemistry of high-grade serous carcinoma, affects muscle layer without going past . Foci associated with ICT. Ovarian serous carcinoma in high grade metastatic salpinge was evident.

Un melanoma amelanótico con metástasis a la glándula tiroides. Descripción clinico-patológica de un caso / Amelanotic anorectal melanoma metastatic to the thyroid gland. A case report

A pesar de su rico aporte vascular, las metástasis en la glándula tiroides son eventos raros. Los carcinomas renales, colorectales, de pulmón y mama son las fuentes más frecuentes de metástasis. Presentamos el caso de una mujer de 75 años de edad, con el antecedente de un melanoma anorrectal amelanótico avanzado, operado un año antes, que se presentó con un crecimiento nodular rápido de la glándula tiroides, por lo que fue sometida a una tiroidectomía parcial. Histopatológicamente, el lóbulo tiroideo mostró una infiltración difusa por melanoma amelánico. Aunque se han publicado algunos casos de metástasis de melanoma en la glándula tiroides, la mayoría de ellos son de origen cutáneo por lo que, a nuestro entender, nosotros presentamos el primer caso de un melanoma anorrectal con metástasis a la glándula tiroide (AU)

Despite its rich vascular supply, metastases to the thyroid gland are rare. Renal, colorectal, lung and breast carcinomas are the most frequent sources of metastases. We report the case of a 75-year-old woman who presented with a rapid nodular enlargement of the thyroid gland, for which she underwent a partial thyroidectomy. She had a history of advanced amelanotic anorectal melanoma surgically treated one year previously. Histopathologically, the thyroid lobe showed diffuse infiltration by an amelanotic melanoma. Although a few cases of metastases of melanoma to the thyroid gland have been reported, the majority are derived from a cutaneous primary; to the best of our knowledge, this is the first reported case of an anorectal melanoma with metastasis to the thyroid gland (AU)

Displasia mesenquimática placentaria. Presentación de un caso / Placental mesenchymal dysplasia. A case report

La displasia mesenquimática placentaria es una patología caracterizada por placentomegalia, alteraciones vasculares y vellosidades edematizadas. Frecuentemente se confunde con la mola hidatiforme, pero a diferencia de esta última no tiene potencial de malignización y permite, salvo algunas complicaciones, el desarrollo normal de la gestación. En este artículo informamos un nuevo caso, diagnosticado después del parto, asociado a retardo en el crecimiento intrauterino. Discutimos también la fisiopatología, la utilidad de p57 y el diagnóstico diferencial de esta entidad(AU)

Placental mesenchymal dysplasia (PMD) is characterized by placentomegaly, vascular alterations and oedematous villi and is often confused with hydatidiform mole; however, unlike the latter, it has no malignant potential and normal gestation is possible although complications may occur. We report a case of PMD, diagnosed after delivery, which was associated with intrauterine growth restriction. The pathophysiology, usefulness of p57 and differential diagnosis of PMD is discussed(AU)

Cerebrovascular blood flow during the near syncopal phase of head-up tilt test: a comparative study in different types of neurally mediated syncope.

AIMS: This study analyses the changes in cerebral blood flow (CBF) velocity occurring in the near syncopal phase of head-up tilt test (HUT) to determine whether their appearance during the premonitory symptoms permits the differentiation of the different types of haemodynamic response. METHODS AND RESULTS: Six hundred and nineteen patients aged 35.9 +/- 16.4 with a prior history of syncope (55%) or presyncope (45%) were studied. Head-up tilt test was positive in 585 patients. The test was interrupted before syncope, once hypotension was evident and CBF changed. A vasovagal reaction (VVR) was observed in 245 patients. They had a 59% fall in diastolic CBF velocity, whereas systolic CBF velocity decreased by 12%. Postural orthostatic tachycardia syndrome (POTS) was observed in 82, systolic and diastolic CBF velocity decreased 44 and 60%, respectively. A similar response was observed in 258 patients with the orthostatic intolerance (OI) pattern. No significant changes were observed in the negative group. CONCLUSION: Patients with VVR had changes in CBF velocity, which are different from those presented by patients with POTS and OI pattern. Cerebral blood flow monitoring is useful to increase the yield of HUT and may allow early interruption before syncope occurs, reducing patient discomfort.
