Primary leiomyosarcoma of the vagina: a case report involving a TVT allograft

Primary vaginal leiomyosarcoma: A case report with complete morphological, immunohistochemical and ultrastructural study

OBJECTIVE

Primary vaginal leiomyosarcomas (LMS) are rare, easily recurrent tumours with an unknown etiology; the prognosis is poor and there is no consensus guideline on their management.

CASE REPORT

A nodular, 25 × 23 x 28 mm-mass, infiltrating the urethra, was found in a 58-year-old woman. A biopsy showed a LMS of the vagina that was positive for vimentin, alpha-smooth muscle actin, caldesmon, desmin, p16 and p53. An anterior pelvic exenteration was performed. The sample was fixed and prepared for light microscopy, transmission and scanning electron microscopy, confirming the diagnosis of LMS.

CONCLUSIONS

Best outcomes occur when the tumour is small, localized, and can be removed surgically with wide, clear margins, as in this case. As there are different kinds of malignant mesenchymal tumours, biopsy followed by immunohistochemistry and electron microscopy still represents a good diagnostic choice and surgical resection is generally the gold standard in these cases.

Primary vaginal leiomyosarcoma: case report of a rare gynaecological malignancy and diagnostic challenge in a resource-constraint setting

Primary vaginal leiomyosarcoma (VLMS) is an extremely rare variant of primary vaginal cancers with very poor prognosis irrespective of the stage at presentation and the type of treatment received. It is easily recurrent and has a high propensity for haematogenous spread especially to the lungs. We present the case of a 34-year-old Para 1 + 1 (1 alive) woman with recurrent vaginal mass of 8 years duration after two surgical excisions without histological evaluation. She had examination under anaesthesia and a wide local excision of the vaginal mass. Histological examination of the mass revealed poorly differentiated VLMS with positive surgical margins and she was commenced on adjuvant chemo-radiation. Histological evaluation remains the hallmark for diagnosing rare malignancies like VLMS, which unfortunately is not a standard practice in some resource-constraint settings.

Tumor-Like Reaction to Polypropylene Mesh from a Mid-Urethral Sling Material Resembling Giant Cell Tumor of Vagina

Background

Polypropylene material is widely used in gynecological surgery. There are few reports regarding its carcinogenic potential. There is lack of evidence supporting tumor formation directly attributed to the use of polypropylene material.

Case

This patient is a 49-year-old woman with a history of stress urinary incontinence which required a MiniArc® Sling who presented with a hard, tender, immobile mass on the anterior vaginal wall. Pathological analysis of the mass revealed a tumor-like reaction to the polypropylene material that resembled a giant cell tumor of soft tissue.

Conclusion

The use of polypropylene in surgery is ubiquitous across disciplines; thus consideration for a tumor-like reaction to the material should exist for patients who present with a mass near the surgical site.

Leiomyosarcoma of the vagina: A rare entity with comprehensive review of the literature

Primary malignant lesions of the vagina are uncommon, and vaginal sarcomas are even rarer. We describe a rare case of stage I, high-grade leiomyosarcoma of the vagina treated with combined modality treatment. A 39-year-old female presented with vaginal mass and underwent resection. Histopathological examination revealed atypical leiomyoma of the vagina with definite risk of recurrence. Eleven months later, she presented with a recurrent vaginal mass and underwent exploratory laparotomy with total abdominal hysterectomy and bilateral salpingo-oophorectomy plus resection of recurrent tumor and partial vaginectomy. The detailed histopathological examination was suggestive of leiomyosarcoma of the vagina. The patient received adjuvant radiotherapy and chemotherapy. The patient is alive and disease-free 29 months postsurgery. Experience with vaginal leiomyosarcomas is limited. The optimal treatment methods have not yet been established because of the rarity of the tumor. We add another case of leiomyosarcoma of the vagina to the limited existing literature.

Leiomyosarcoma of the vagina: case report and literature review

Leiomyosarcoma of the vagina is quite rare. Extensive search of the literature discloses 137 case reports published over the past 40 years. Collectively, these reports give only cursory guidelines for diagnosis, management, and prognosis. We add another case to the sparse literature on leiomyosarcoma of the vagina. Treatment consisted of surgical excision. Tumor was found to extend to the margin of the excised specimen. The malignancy quickly recurred with lung metastases and the patient died. The very poor prognosis associated with this lesion emphasizes the critical need for early diagnosis and expeditious therapy. In the interest of improving salvage by prompt recognition and intervention, it is important for health-care professionals to be knowledgeable about and alert to this condition.
