Lymphangioma of the ovary

Lymphangioma of the ovary is an extremely rare lesion. There are only 19 cases reported in the literature. Lymphangioma is usually unilateral and asymptomatic, presenting as an incidental finding during routine gynaecologic procedures. It is composed of aggregates of lymphatic spaces in ovarian stroma and the endothelial cells lining these spaces stain positively with CD-31 and CD-34 on immunostaining. The main differential diagnosis is an adenomatoid tumour which can be differentiated from the lymphangioma by immunohistochemical studies. We report this rare lesion in a 42-year-old Malay lady diagnosed after total abdominal hysterectomy and right salpingo-oophrectomy. A literature review is presented and the histological and immunohistological findings along with differential diagnosis are discussed.

Unusual Presentation of a Rare Para Testicular Tumour in a Child.

Adenomatoid tumour epididymis usually present as painless scrotal mass during 2nd or 3rd decade of life. The case presented is a seven years old boy admitted with acute painful swelling of the scrotum. The scrotum was explored on the suspicion of torsion testis but testis was found to be normal and the epididymis enlarged. Biopsy from epididymis showed Adenomatoid tumour. Surgical exploration was performed through the same inguinal incision later and tissue sent for histopathological examination confirmed “adenomatoid tumour with surrounding inflammatory mass”.

Tumor adenomatoide del tracto genital femenino: Informe de dos casos de cuerpo uterino y ovario, y revisión de la literatura / Adenomatoid tumour of the female genital tract: A report of two cases located in the uterine body and ovary and review of the pertinent literature

Objetivo: informar dos casos de tumor adenomatoide (TA) del tracto genital femenino y efectuar una revisión de la literatura, con énfasis en sus aspectos histopatológicos y diagnóstico diferencial. Presentación de los casos: se informan dos casos de TA del tracto genital femenino, diagnosticados mediante estudios histológicos y de inmunohistoquímica de piezas quirúrgicas. El primero corresponde a una paciente de 39 años que consultó por hemorragia uterina, a quien se le realizó diagnóstico clínico y ecográfico de miomatosis uterina, para el cual se le practicó histerectomía y cuyo estudio patológico demostró un tumor adenomatoide del cuerpo uterino. El segundo caso se presentó en una paciente de 26 años con masa de ovario izquierdo, cuyo material histológico fue remitido para consulta con diagnóstico inicial de tumor de seno endodérmico. Discusión: el TA es un tumor benigno de origen mesotelial, infrecuente en el tracto genital femenino, cuyo tratamiento sólo requiere cirugía conservadora. Su diagnóstico diferencial incluye tumores malignos primarios y metastáticos, tanto del cuerpo uterino como del ovario, que de acuerdo con su estado clínico, requieren para su manejo cirugía oncológica y quimioterapia y/o radioterapia complementarias.

Objective: reporting two cases of adenomatoid tumour (AT) of the female genital tract and to reviewing the pertinent literature, emphasising histopathological features and differential diagnosis. Cases report: two cases of AT of the female genital tract are reported; they were diagnosed by histological and immunohistochemistry studies of surgical specimens. The first case concerned a 39-year-old woman who consulted for uterine bleeding; uterine myomatosis was suggested by clinical and ultrasonographic diagnosis, but the pathological study revealed an AT. The second case concernid a 26-year-old woman with a left ovarian mass. Ooforectomy initially diagnosed the histological material as endodermal sinus tumour and it was then sent for consultation. Discussion: AT is an infrequently occurring mesothelial benign tumour of the female genital tract; its treatment only requires conservative surgery. Its differential diagnosis includes malignant primary and metastatic tumours of both the uterine body and the ovaries, requiring oncologic resection and complementary chemo-and/or radiotherapy, according to their clinical state.

Tumor odontogenico adenomatoide: Reporte de un caso y revisión de la literatura

El Tumor Odontogéncio Adenomatoide es una lesión clasificada por la OMS dentro de los tumores odontogénicos con participación del ectomesénquima, ya que puede contener, además del epitelio, tejido calcificado en su interior (1). Es una lesión de crecimiento lento y poco invasiva pero que se puede asemejar a otras lesiones odontógenas de mayor agresividad como el quiste dentígero y el ameloblastoma entre otros. Su localización clásica (área de caninos superiores) nos orienta al diagnóstico y su patrón histológico ductiforme es muy propio de este tumor (1). Se hace una revisión de la literatura acerca de este tumor odontogénico benigno, sus características clínicas, radiográficas, tratamiento, así como los diagnósticos diferenciales que se deben tener en cuenta, y se reporta un caso.

Resumo O tumor Odontogéncio Adenomatoide é um ferimento classificado pelo OMS dentro dos tumores odontogénicos com participação de ectomesénquima, desde que pode conter, além ao epitelio, o tejido calcificado no seu interior(1). É um ferimento invasivo pequeno do crescimento lento e, mas aquele pode serás semelhou-se a outros ferimentos dos odontógenos de um agressividade maior como quisto e o ameloblastoma dentígero entre outro. Sua posição clássica (área de superior canine) orienta-nos ao diagnóstico e seu teste padrão do histológico do ductiforme são possuem muito deste tumor (1). Uma revisão acontece com a literatura sobre este odontogénico benigno tumor, suas características clínicas, radiográficas, tratamento, os diferenciais dos diagnósticos que são devidos considerar, e um caso é relatado.

Summary The Odontogenic Adenomatoid Tumour is clasifyed for the WHO as an odontogénic neoplasm with connective tissue formation, so it can contain hard tissue inside It presents as a slow growing mass and it is not much invasive but it can be similar to other more invasive lesions as the folicular cyst , ameloblastoma and others. It´s seen more frecuently in the uper cuspid area and this finding helps us in the diagnosis, and the histologic findings as duct formations is very caracteristic. In this work we made a literature revision about the clinical, radiografic and histologic findins and treatment as the diferential diagnosis and we report one case.
