Lipoleiomioma uterino

El lipoleiomioma es una neoplasia uterina benigna poco frecuente cuya incidencia varía entre 0,03% y 0,2%. Este tumor es considerado una variante benigna de los leiomiomas uterinos típicos. Está formado por una proporción variable de adipocitos maduros y células musculares lisas. La etiología puede estar relacionada con la deficiencia de estrógenos que se produce después de la transición menopáusica; generalmente aparece en mujeres obesas perimenopáusicas o menopáusicas. La sintomatología es inespecífica y la mayoría es diagnosticada de forma incidental. Se presenta un caso de lipoleiomioma uterino en paciente de 45 años quien consultó por presentar dolor abdominal. La ecografía mostró tumor en pared anterior de un útero homogéneo y bien definido. Durante la laparotomía se encontró tumor amarillento y de textura blanda. Se realizó histerectomía total más ooforosalpingectomía. El diagnóstico anatomopatológico fue de lipoleiomioma uterino.

Lipoleiomyoma is a rare benign uterine neoplasm whose incidence varies between 0.03%-0.2%. This tumor is considered a benign variant of typical uterine leiomyomas. It consists of a variable proportion of mature adipocytes and smooth muscle cells. The etiology may be related to estrogen deficiency occurring after the menopausal transition; it usually appears in obese perimenopausal or menopausal women. The symptomatology is nonspecific, and most are diagnosed incidentally. We present a case of uterine lipoleiomyoma in a 45-year-old patient who consulted for abdominal pain. Ultrasonography showed a tumor in the anterior wall of a homogeneous and well-defined uterus. During laparotomy, a yellowish tumor with a soft texture was found. Total hysterectomy plus oophorosalpingectomy was performed. The anatomopathologic diagnosis was uterine lipoleiomyoma.

Lipoleiomioma uterino: un hallazgo inusual / Uterine lipoleiomyoma: an unusual finding

Los tumores lipomatosos uterinos son lesiones generalmente benignas, de patogenia incierta y muy baja incidencia. Habitualmente se presentan en mujeres posmenopáusicas y el diagnóstico preoperatorio es difícil debido a que se confunden clínicamente y ecográficamente con leiomiomas. Usualmente son asintomáticos pero pueden manifestarse con metrorragia, dolor pélvico y masa palpable. El tumor lipomatoso uterino más frecuente es el lipoma mixto cuya denominación dependerá de las proporciones de tejido adiposo y conectivo que lo constituyan. El manejo puede ser conservador o quirúrgico dependiendo del tamaño y sintomatología de la paciente. Se presenta el caso de una mujer de 50 años, con un tumor uterino diagnosticado preoperatoriamente como leiomioma y con diagnóstico histopatológico de lipoleiomioma.

The uterine lipomatous tumors are usually benign lesions, of uncertain pathogenesis and very low incidence. They are often presented in postmenopausal women and the preoperative diagnosis is difficult because they are confounded clinically and sonographically with leiomyomas. They are frequently asymptomatic but may present with metrorrhagia, pelvic pain and palpable mass. The most common uterine lipomatous tumor is the mixed lipoma whose denomination depends on the proportions of fat and connective tissue. The conservative or surgical management will depend on the size of the tumor and the patient symptoms. We present a case report of a 50 year- old woman with a uterine tumor diagnosed preoperatively as leiomyoma and whose histopathological diagnosis was lipoleiomyoma.

Lipoleiomioma primario del útero / Primary Uterine Lipoleiomyoma

Se presentó una paciente femenina de 59 años de edad, raza blanca y procedencia rural con antecedentes de diabetes mellitus tipo 1 con tratamiento con insulina lenta (15 unidades en desayuno, almuerzo y comida) además, padece de hipertensión arterial tratada con captopril (25 mg cada ocho horas), que acudió a consulta de Cirugía General refiriendo dolor abdominal localizado en hipogastrio que se irradia a fosas lumbares, de seis meses de evolución, intensidad moderada, que se aliviaba con dipirona cada ocho horas y sin otro síntoma. Al ser estudiada e intervenida quirúrgicamente se realizó el diagnóstico de lipoleiomioma primario del útero, considerada una neoplasia benigna poco frecuente reportada en la literatura.

A 59-year-old white female patient, of rural origin was presented in this paper with a history of type 1 diabetes mellitus with insulin treatment (15 units at breakfast, lunch and dinner). She also suffered from high blood pressure, treated with captopril (25 mg every eight hours). The patient had hypogastric abdominal pain, radiated to septic lumbar (six months duration), moderate intensity, which was relieved with dipyrone every eight hours and no other symptoms. The patient was studied and underwent surgery. An uterine primary lipoleiomyoma was diagnosed, considered a rare benign neoplasia reported in the literature.

Lipoleiomyoma associated to uterine prolapse: a case report / Lipoleiomioma associado a prolapso uterino: relato de caso

Lipoleiomyoma is a rare benign tumor of the uterus, with an incidence ranging between 0.03 por cento and 0.2 por cento. DESCRIPTION: the authors report a case of lipoleiomyoma diagnosis in an 82-year-old woman with a totally prolapsed uterus. DISCUSSION: lipoleiomyoma is most common among postmenopausal women and is associated with ordinary leiomyomas. Histologically it is composed of smooth muscle, adipocytes and fibrous tissue. In general asymptomatic, the diagnosis usually involves imaging studies such as ultrasound and computed tomography of the pelvis...
