The presence of cartilage in MMMT is considered a favorable prognostic factor.8 Uterine sarcoma accounts for 3-5% of all corpus uteri malignancies; undifferentiated uterine sarcomas arise from the endometrium or myometrium, lacking any resemblance to normal endometrium and may show heterologous stromal elements in the form of cartilage, bone or rhabdomyoblasts.9 In our case the hyaline cartilage nodules were mostly located deep in the myometrium, close to the serosal surface and adjacent tissue exhibited foci of adenomyosis; the closest differential diagnosis ruminated was adenosarcoma
have a biphasic morphology comprising of benign epithelial elements and malignant stromal elements.10
The majority of uterine adenosarcomas
recur locally, suggesting that resection of a local recurrence may improve overall survival and time to next recurrence.
Mikaelian y Reavill , describieron de manera clinica lesiones proliferativas uterinas en 15 hembras de erizo de tierra africano en cautiverio, entre estas se encuentran: adenosarcomas
, sarcomas del estroma endometrial, adenoleiomiosarcoma y adenoleiomioma, indicando que dichas lesiones en su mayoria cursan con hematuria, por lo tanto, es imprescindible evaluar la cavidad abdominal para verificar la procedencia del sangrado, que puede ser, tanto uterino como urinario.
with sarcomatous overgrowth in young patients are very rare.
Diffuse or multifocal expression of CD10 in the stromal compartment is seen in most adenosarcomas
and often highlights the periglandular cuffing (Figure 7).
(2) The occurrence of this tumour type is unusual and its pathogenesis is not completely understood since epithelial cells are not normally present in the retroperitoneum for adenomas and adenosarcomas
The study group included 7 cases of squamous cell carcinoma, 10 adenocarcinomas, 4 adenosquamous tumors, 2 adenosarcomas
, and 2 neuroendocrine tumors.
The majority of uterine corpus cancers are endometrial carcinomas, with the remaining cases (3%-5%) being sarcomas (stromal sarcomas, leiomyosarcomas, undifferentiated sarcomas, adenosarcomas
The pathology slides from the initial diagnosis were reexamined and the diagnosis of uterine LMS was verified, while definitively excluding epithelial tumors, carcinosarcomas, endometrial stromal tumors, adenosarcomas
, and undifferentiated uterine sarcomas.
Of the 64 patients who had a preoperative CT scan of the abdomen and pelvis, the histology included 46 adenocarcinomas, 2 adenosquamous carcinomas, 3 adenosarcomas
, 11 papillary squamous or clear cell carcinomas, and 2 squamous cell carcinomas.
Hysterectomy was recommended, because an adenosarcoma
may be present within the residual tumor or an adenofibroma may develop invasive potential and recur [4, 5].
