Intravenous Leiomyomatosis of the Uterus: A Retrospective Single-Center Study in 14 Cases.

ABSTRACT: Purpose:This study aimed to retrospectively review the diagnosis and surgical treatment of uterine intravenous leiomyomatosis (IVL). Methods:The clinical data of 14 patients with uterine IVL admitted to our hospital between 2013 and 2018 were retrospectively analyzed, including their demographics, imaging results, surgical procedures, perioperative complications, and follow-up results. Results:The tumors were confined to the pelvic cavity in 7 patients, 1 into the inferior vena cava, 4 into the right atrium, and 2 into the pulmonary artery (including 1 into the superior vena cava). Only one case was misdiagnosed as right atrial myxoma before the operation, which was found during the surgery and was treated by staging surgery; all the other patients underwent one-stage surgical resection. Three patients underwent complete resection of the right atrial tumor through the abdominal incision, and one patient died of heart failure in the process of resection of heart tumor without abdominal surgery. During the 6-60 months of follow-up, 4 patients developed deep venous thrombosis of the lower extremity, and 1 patient developed ovarian vein thrombosis and pulmonary embolism. After anticoagulation treatment, the symptoms disappeared. One patient refused hysterectomy and the uterine fibroids recurred 4 years after the operation. Conclusion:Specific surgical plans for uterine IVL can be formulated according to cardiac ultrasound and computed tomography (CT). For the first type of tumor involving the right atrium, the right atrium tumor can be completely removed through the abdominal incision alone to avoid thoracotomy. The disease is at high risk of thrombosis and perioperative routine anticoagulation is required.

Project description:BackgroundIntravenous leiomyomatosis (IVL) is a rare, difficult-to-treat type of smooth muscle tumor that originates from the uterine myoma. However, its clinical characteristics, management, and prognosis are not clearly understood. Moreover, the 2 different methods used to diagnose IVL-incidental and nonincidental-result in completely different treatments.MethodsWe conducted a single-center, retrospective study. Our real-life case series included patients pathologically diagnosed with IVL between July 2011 and December 2020. All patients with IVL were divided into 2 groups: an incidental group and a nonincidental group. Medical records of patients, including clinical characteristics, primary treatment, treatment after recurrence, and prognosis, were reviewed.ResultsA total of 39 patients were included in the study, with a median patient age of 47 years. Of the 39 cases, 15 (38.5%) were incidentally diagnosed with only intrapelvic tumors. Among the 24 patients with IVL in the nonincidental group, tumor spread in the inferior vena cava, right heart, and pulmonary artery was identified in 4, 17, and 3 patients, respectively. The most common symptoms were abnormal uterine bleeding in the incidental group and chest distress and dyspnea in the nonincidental group. Among the 15 patients in the incidental group, ovary-preserving surgery was performed in 6 young women (≤40 years old), of whom 3 underwent myomectomy. All 24 patients with IVL in the nonincidental group underwent thrombectomy without uterine or ovary preservation by multidisciplinary surgical treatment. Only 1 patient in each group underwent postoperative adjuvant therapy. During the median follow-up of 36.0 months, recurrence was recorded in 5 (12.8%) cases in the incidental group, with no deaths recorded. Only 1 patient was lost to follow-up. No recurrence was noted in the cases in the nonincidental group. Among the 5 patients who experienced recurrence, 4 received secondary surgical treatment and 1 received hormone therapy. All patients were alive as of this report.ConclusionsPatients with IVL who are diagnosed incidentally have a higher recurrence risk than those who are diagnosed nonincidentally and undergo complete tumor resection. However, patients incidentally diagnosed with IVL can still experience long disease-free survival rates following secondary surgical treatment after recurrence.

Project description:BackgroundSporotrichosis is a subcutaneous or implantation mycosis caused by some species of the genus Sporothrix. Rio de Janeiro state, Brazil, experiences hyperendemic levels of zoonotic sporotrichosis, with increasing cases of disseminated disease, especially in people living with HIV (PLHIV). Involvement of the nasal mucosa is rare and occurs isolated or in disseminated cases, with a delayed resolution.Methodology/principal findingsThis study aimed to describe the epidemiological, clinical, and therapeutic profiles of 37 cases of sporotrichosis with involvement of the nasal mucosa treated at the ear, nose, and throat (ENT) outpatient clinic of the Instituto Nacional de Infectologia Evandro Chagas, Fundação Oswaldo Cruz, from 1998 to 2020. Data were reviewed from the medical records and stored in a database. The Mann-Whitney test was used to compare the means of quantitative variables, and Pearson chi-square and Fisher's exact tests were used to verify the association between qualitative variables (p<0.05). Most patients were males, students or retirees, with a median age of 38 years, residents in the municipality of Rio de Janeiro, and infected through zoonotic transmission. Disseminated sporotrichosis forms in patients with comorbidities (mostly PLHIV) were more common than the isolated involvement of the mucosa. The main characteristics of lesions in the nasal mucosa were the presence/elimination of crusts, involvement of various structures, mixed appearance, and severe intensity. Due to therapeutic difficulty, itraconazole was combined with amphotericin B and/or terbinafine in most cases. Of the 37 patients, 24 (64.9%) healed, with a median of 61 weeks of treatment, 9 lost follow-up, 2 were still treating and 2 died.ConclusionsImmunosuppression was determinant to the outcome, with worse prognosis and lower probability of cure. Notably in this group, the systematization of the ENT examination for early identification of lesions is recommended to optimize the treatment and outcome of the disease.

Project description:Intravenous leiomyomatosis (IVL) is an unusual uterine smooth muscle proliferation that can be associated with aggressive clinical behavior despite a histologically benign appearance. It has some overlapping molecular characteristics with both uterine leiomyoma and leiomyosarcoma based on limited genetic data. In this study, we assessed the clinical and morphological characteristics of 28 IVL and their correlation with molecular features and protein expression, using array comparative genomic hybridization (aCGH) and Cyclin D1, p16, phosphorylated-Rb, SMARCB1, SOX10, CAIX, SDHB and FH immunohistochemistry. The most common morphologies were cellular (n = 15), usual (n = 11), and vascular (n = 5; including 3 cellular IVL showing both vascular and cellular features). Among the immunohistochemical findings, the most striking was that all IVL showed differential expression of either p16 or Cyclin D1 in comparison to surrounding nonneoplastic tissue. Cytoplasmic phosphorylated-Rb was present in all but one IVL with hyalinization. SMARCB1, FH, and SDHB were retained; S0X10 and CAIX were not expressed. The most common genetic alterations involved 1p (39%), 22q (36%), 2q (29%), 1q (25%), 13q (21%), and 14q (21%). Hierarchical clustering analysis of recurrent aberrations revealed three molecular groups: Groups 1 (29%) and 2 (18%) with associated del(22q), and Group 3 (18%) with del(10q). The remaining IVL had nonspecific or no alterations by aCGH. Genomic index scores were calculated for all cases and showed no significant difference between the 14 IVL associated with aggressive clinical behavior (extrauterine extension or recurrence) and those without (median scores 5.15 vs 3.5). Among the 5 IVL associated with recurrence, 4 had a vascular morphology and 3 had alterations of 8q. Recurrent chromosome alterations detected herein overlap with those observed in the spectrum of uterine smooth muscle tumors and involve genes implicated in mesenchymal tumors at different sites with distinct morphological features.
