Leiomioma vaginal de crecimiento rápido. Reporte de un caso / Rapidly growing vaginal leiomyoma. A case report

Resumen Antecedentes: Los leiomiomas vaginales son tumores poco frecuentes. Hasta la fecha solo se han reportado 330 casos en la bibliografía internacional. Caso clínico: Paciente de 37 años, que acudió al servicio médico por percibir una tumoración de crecimiento rápido en la vagina. A la exploración física se objetivó una masa de consistencia dura, no dolorosa a la palpación, de aproximadamente 30 mm de diámetro medio, ubicada en el tercio inferior de la cara lateral derecha de la vagina, compatible con mioma vaginal. En ese momento la paciente se negó a recibir tratamiento. Después de algunos meses acudió, nuevamente, a consulta debido a molestias vaginales, metrorragias mayores al ciclo menstrual y dispareunia. La ecografía y resonancia magnética mostraron una tumoración de gran tamaño (58 x 57 x 60 mm), redondeada y de aspecto sólido, situada en el espacio vesicovaginal. Con estos datos se estableció el diagnóstico de leiomioma vaginal pediculado. Para disminuir el volumen y sangrado de los miomas se le prescribieron 5 mg al día de acetato de ulipristal. Después de dos ciclos de tratamiento se objetivó un incremento de la tumoración, que alcanzó 70 x 55 mm. Se decidió efectuar la miomectomía por vía vaginal, sin advertir claramente el pedículo dependiente del útero y el cuello uterino. El posoperatorio trascurrió sin contratiempos. El estudio histopatológico confirmó el diagnóstico de leiomioma vaginal. Conclusión: Los signos y síntomas (sangrado o manchado anormal, secreción vaginal, dolor o masa pélvica) de los leiomiosarcomas extrauterinos dificultan de emitir recomendaciones precisas para establecer el diagnóstico y tratamiento.

Abstract Background: Vaginal leiomyomas are exceptional tumours. Only 330 cases have been reported in the world literature. Clinical case: Patient of 37 years old, with a vagina tumour of rapid growth. The physical examination showed a mass of hard consistency, without pain on palpation, of approximately 30 mm in average diameter, in the lower third of the right lateral of the vagina, compatible with the vaginal myoma. At that time the patient refused to receive treatment. After a few months, a consultation for vaginal discomfort, metrorragia greater than the menstrual cycle and dyspareunia. Ultrasonography and magnetic resonance showed a tumour that increased in size (58 x 57 x 60 mm), had a rounded shape and a solid appearance, located in the vesicovaginal space. With these data the diagnosis of pediculated vaginal leiomyoma was established. Ulipristal acetate (5 mg / day) was prescribed to decrease volume and myomatous bleeding. After two treatment cycles, an increase in the tumour was observed, which reached a size of 70 x 55 mm. It was decided to perform myomectomy vaginally, without objectifying the pedicle dependent on the uterus and the cervix. The postoperative period was uneventful. The histopathological study confirms the diagnosis of vaginal leiomyoma. Conclusion: The signs and symptoms (bleeding or abnormal staining, vaginal discharge, pain or pelvic mass) of the extrauterine leiomyosarcomas make it difficult to establish precise recommendations to establish the diagnosis and treatment.

Linfoma ósseo primário simultâneo a osteocondroma simulando degeneração sarcomatosa: relato de caso / Primary bone lymphoma simultaneous to osteochondroma simulating sarcomatous degeneration: case report

Não há evidências relatadas na literatura de associação entre linfoma ósseo primário e osteocondroma ou da coexistência deles em uma mesma região óssea. Este relato de caso descreve um caso raro de linfoma ósseo primário ocorrendo juntamente com um osteocondroma no terço proximal de tíbia. Os sinais de imagem na ressonância magnética neste caso simulam uma degeneração sarcomatosa do osteocondroma.

In the literature, there is no evidence of relationship between primary bone lymphoma and osteochondroma or of coexistence of both of them in a single bone. The present report describes an uncommon case of primary bone lymphoma occurring simultaneously with osteochondroma in the proximal third of the tibia. In the present case, magnetic resonance imaging signs simulated the presence of sarcomatous degeneration.

Diagnóstico ecográfico de mioma uterino en mujeres con síntomas ginecológicos / Ultrasound diagnosis of uterine myoma in women with gynecological symptoms

Se realizó un estudio descriptivo y transversal de 76 pacientes atendidas en el Departamento de Ultrasonido del Hospital "Carlos Manuel de Céspedes" de Bayamo, Granma, desde junio de 2011 hasta enero de 2012, con vistas a describir las características ecográficas del mioma uterino en mujeres con síntomas ginecológicos. Entre las variables analizadas figuraron: edad, color de la piel, hallazgos ecográficos y correspondencia entre el diagnostico presuntivo y el ecográfico. En la serie prevalecieron las diagnosticadas con mioma uterino, el grupo etario de 15-45 años y las féminas de piel negra. Asimismo, predominaron los miomas múltiples y de localización intramural. Las complicaciones que primaron fueron la degeneración quística y las calcificaciones. No hubo total correspondencia entre las indicaciones médicas presuntivas de miomas y el diagnóstico ecográfico definitivo.

A descriptive and cross-sectional study was conducted in 76 patients attended in the Ultrasound Department of "Carlos Manuel de Céspedes" Hospital in Bayamo, Granma, from June 2011 to January 2012, in order to describe the sonographic characteristics of the uterine myoma in women with gynecological symptoms. Among the analyzed variables were age, race, sonographic findings and correspondence between the presumptive and sonographic diagnosis. Those diagnosed with uterine myoma, age group of 15-45 years and black women prevailed in the series. Also, multiple myomas and those of intramural location prevailed. Cystic degeneration and calcifications were the prevailing complications. There was not total correspondence between the presumptive medical indications of myomas and the final ultrasound diagnosis.

Degeneração sarcomatosa de doença de Paget do calcâneo: relato de caso / Sarcomatous degeneration of Paget's disease in the calcaneus: a case report

A degeneração maligna das lesões da doença de Paget é rara (cerca de 1% dos casos), sendo de mau prognóstico apesar do tratamento. Relatamos o caso de um paciente de 82 anos de idade, portador de doença de Paget há vários anos, em que se identificaram, nos exames de imagem, características de degeneração maligna no calcâneo, com anatomopatológico evidenciando degeneração sarcomatosa do osso.

Neoplastic degeneration in Paget's disease is a rare complication (approximately 1% of cases) and, despite the treatment, presents a poor prognosis. The authors report a case of a male, 82-year-old patient with long standing Paget's disease who presented imaging findings of malignant degeneration in the calcaneus histopathologically diagnosed as sarcomatous degeneration.
