Vaginal metastasis as the initial presentation of leiomyosarcoma: a case report.

ABSTRACT: Uterine leiomyosarcomas are very rare and highly aggressive tumors that have a high rate of recurrence and poor prognosis, even when early diagnosed. Due to their relative rarity, there is limited research on optimal management strategies.A 60-year-old woman with a history of an asymptomatic uterine leiomyoma presented in October 2015 with postmenopausal bleeding and a friable vaginal cyst that bled when palpated. A partial cystectomy was performed, and malignant-like cystic and solid components were identified. Histopathology diagnosed an unclassifiable malignant epithelioid tumor. Subsequent imaging studies identified a malignant uterine tumor, a metabolically active vaginal lesion, and two benign leiomyomas. An anterior pelvic exenteration (colpectomy, hysterectomy, bilateral adnexectomy, total cystectomy, and cutaneous ureteroileostomy ad modum Bricker) were performed by laparotomy in March 2016. Examination of the surgical specimens identified a 75 × 75-mm leiomyoma, an 80 × 30-mm infiltrating mesenchymal uterine lesion with vascular invasion and tumor emboli, and a 60 × 30-mm perivascular vaginal tumor. Immunohistochemistry indicated a phenotypic transition from a uterine leiomyosarcoma to a vaginal epithelioid lesion; marker expression changed from the uterine tumor actin+/desmin+/caldesmon+/CD10- phenotype, through the tumor emboli, to an actin-/desmin-/caldesmon-/CD10+ phenotype in the vaginal lesion. A high-grade uterine mesenchymal tumor and vaginal metastasis were diagnosed. Adjuvant chemotherapy with docetaxel, gemcitabine, and doxorubicin commenced in May 2016 and treatment has been well tolerated.Differentiating leiomyosarcoma from leiomyoma is challenging and few tools other than microscopic evaluation are available. Vaginal compromise in leiomyosarcoma usually results from tumor extension, not hematogenous metastasis. A vaginal metastasis is a very rare initial presentation. We have found only two cases like this described on published literature. The atypical clinical and histological presentation in our case complicated diagnosis and delayed treatment. An early diagnosis and complete surgical clearance gives the best chance of survival, and imaging tools should be applied early in instances of new suspicious malignant lesions.

Project description:RationaleMetastasis of neoplasms to the eye is quite uncommon. In this case report, we describe a patient where primary esophageal cancer was diagnosed by fine needle aspiration biopsy (FNAB) of an iris tumor.Patient concernsA 70-year-old male complained of redness and discomfort in the right eye.Diagnosis and interventionsThe patient's right eye was diagnosed as idiopathic uveitis, and a topical steroid was administered. As vitreous opacities were observed even after topical therapy, oral prednisolone was administered. On slit-lamp examination of the right eye, an iris mass with neovascularization was seen in the anterior chamber. A metastatic tumor was suspected, and FNAB was performed. Histology revealed squamous cell carcinoma. Systemic workup revealed esophageal cancer with several metastases. Best-corrected visual acuity decreased to 20/400, and intraocular pressure was 40 mmHg in the right eye. Two iris tumors with neovascularization were present extending into the anterior chamber with posterior iris synechiae and 360 degree peripheral anterior synechiae. Intraocular pressure in the right eye was medically managed with hypotensive eye drops and oral acetazolamide. Iris metastases were treated with 40 Gray of radiation therapy and concurrent chemotherapy.OutcomesThe tumor regressed, but intraocular pressure was refractory to treatment because of 360 degree goniosynechial closure. The right eye lost light perception six months after treatment commenced, and the patient died 9 months after the onset of therapy due to multiple systemic metastases.LessonsThis is a rare case of masquerade syndrome without systemic symptoms in which FNAB of an iris tumor led to a diagnosis of metastatic esophageal squamous cell carcinoma. Although the patient lost his sight due to uncontrollable ocular hypertension, systemic chemotherapy, and radiation therapy were initially effective in the treatment of the metastatic iris tumor. As the prognosis of patients with metastatic iris tumors is poor, it is important for ophthalmologists to consider such diagnoses and conduct systemic investigations when necessary.
