Isolated abdominal wall metastasis of endometrial carcinoma

Plastic surgery for giant metastatic endometrioid adenocarcinoma in the abdominal wall: A case report and review of literature

BACKGROUND

Endometrial cancer (EC) is a common gynecological malignancy, but metastasis to the abdominal wall is extremely rare. Therefore, an appropriate treatment approach for large metastatic lesions with infection remains a great challenge.

CASE SUMMARY

We report the case of a 65-year-old woman who developed abdominal metastasis of endometrioid adenocarcinoma, as defined by International Obstetrics and Gynecology stage II, in which the lesion was complicated by infection. A right hemicolectomy was performed for colon metastasis in relation to her initial gynecological cancer 3 years ago. When admitted to our department, a complete resection of the giant abdominal wall lesion was performed, and a Bard composite mesh was used to reconstruct the abdominal wall. A local flap was used to close the resultant large defect in the external covering of the abdomen. The patient underwent chemotherapy following cytoreductive surgery. Pathology revealed metastasis of EC, and molecular subtyping showed copy number high of TP53 mutation, implying a poor prognosis.

CONCLUSION

When EC patients develop giant abdominal wall metastasis, a plastic surgeon should be included before contemplating resection of tumors.

En bloc resection of cervical adenocarcinoma with late recurrence to the iliopsoas

This is a case of a 50-year-old woman diagnosed with recurrent cervical adenocarcinoma presenting with chronic and persistent low back pain. She underwent myomectomy for myoma uteri 8 years prior. Histopathology report revealed cervical cancer. She underwent chemotherapy, brachytherapy and external beam radiotherapy. All surveillance work-up, over the years, were negative until she was found to have a solitary recurrent lesion in the right iliopsoas muscle on CT scan. A multidisciplinary team of surgeons collaborated to perform wide excision of pelvic recurrence en bloc right internal hemipelvectomy, right hemicolectomy en bloc resection of external iliac artery and vein, external ilio-iliac artery interposition graft and external iliac vein-common femoral vein bypass. Final histopathologic results showed adenocarcinoma with endometrioid features with associated poorly differentiated high-grade carcinoma involving the iliopsoas, cecum and terminal ileum. Two months postoperatively, the patient is ambulating with minimal assistance.

Late metastatic endometrial carcinoma at the repair site of an abdominal wall incisional hernia

The abdominal wall is a very rare site for endometrial cancer metastases. Its appearance generally indicates advanced cancer with poor prognosis. We report a case of a 55-year-old female who presented with an incisional hernia 4 years after abdominal panhysterectomy for endometrioid adenocarcinoma in 2009. Open hernia mesh repair was performed but on follow-up, she complained of pain and a swelling at the repair site. This was radiologically diagnosed as fibromatosis, but tru-cut biopsy confirmed presence of fibromatosis as well as a metastatic endometrial carcinoma. She was started on neoadjuvant chemotherapy, but had poor response, and therefore, radical excision was performed. She remained well with no metastatic recurrence at 12-month follow-up. This case illustrates late appearance of abdominal wall metastasis from abdomino-pelvic malignancies and highlights the need to exclude the presence of recurrence or metastases prior to surgical repair of incisional hernia occurring after the resection of abdominal or pelvic malignancy.
