Uterine smooth muscle tumors are the most common gynecological tumors, with an incidence ranging from 5.4% to 77.0%, depending on the diagnostic method. Histopathology represents the gold standard for diagnosis confirmation. Most of these tumors are benign (leiomyomas) but, rarely, they can be malignant (leiomyosarcomas) leading to adverse clinical outcomes and poor long-term prognosis. Since the majority of women have asymptomatic lesions, the real incidence of leiomyoma is not known. However, based on post-mortem examination, a 50% prevalence has been reported[1].

CONCLUSIONS STMN1 and MKI67 were upregulated in uterine leiomyosarcoma and act as potential biomarkers for uterine leiomyosarcoma diagnosis. PMID: 32425177 [PubMed - in process]

Conclusions: The prognosis of STUMP was favorable and tumors with more than 10 mitoses per 10 high power field should be monitored closely. The surgical procedure was not an independent risk factor of recurrence, and myomectomy may be an acceptable option for patients wishing to preserve fertility.

CONCLUSIONS: There are limited data on the effectiveness and safety of in-bag morcellation at the time of laparoscopic myomectomy compared to uncontained power morcellation. We were unable to determine the effects of in-bag morcellation on intraoperative complications as no events were reported in either group. We are uncertain if in-bag morcellation improves total operative time or ease of morcellation compared to control. Regarding morcellation operative time, the quality of the evidence was also very low and we cannot be certain of the effect of in-bag morcellation compared to uncontained morcellation. No cases of posto...

Abstract“Benign” metastatic leiomyomas (BML) are indolently growing metastatic tumors which mostly associate with uterine leiomyomas in women in reproductive ages. The reason to define these lesions as “benign” despite metastasis is their pathological features with low mitotic counts, lack of or min imal nuclear atypia, pseudocyst formation, and coagulative necrosis unlike leiomyosarcomas. Despite lack of pathological malignant features, they may cause significant morbidity and even mortality. Here, we describe a BML case with metastases to vertebrae and skull bones. Vertebral and skull metasta ses ...

THE MEDICAL DEVICE APPLIED TO UTERINE FIBROIDS MORCELLATION: ANALYSIS OF CRITICAL BIOLOGICAL ISSUES AND DRAWBACKS FROM A MEDICAL-LEGAL PROSPECTIVE. Curr Pharm Des. 2020 Feb 03;: Authors: Ospan A M, Michael S, Antonio M, Radmila S, Enrico M, Simona Z, Andrea T Abstract Following the FDA safety communication of 2014 increasing attention has been to the treatment of uterine fibroids, due to the suspicion of a potential leiomyosarcoma (ULM). FDA banned the use of power morcellation in US, since this technique is likely to spread malignant cells from an unsuspected ULM. We criticized the medical legal cons...

, Zombori T Abstract Pulmonary arterial intimal sarcoma is a rare tumour with high mortality. Due to its localisation, the symptoms can mimic pulmonary thromboembolism and pneumonia, therefore assessing the diagnosis and choosing the adequate therapy is never easy. Its therapy mainly consists of surgery combined with radiochemotherapy. A 46-year-old male patient with testicular seminoma, pulmonary embolism, bronchial asthma and pollen allergy in his history had a follow-up thoracic CT. On the left side of the lung, a pleura-infiltrating 7-8 cm lesion, which occluded the pulmonary artery, was described. The first b...

ConclusionHerein, we describe distinct DNA methylation signatures in uterine neoplasms and show that array-based DNA methylation analysis holds promise as an ancillary tool to further characterize uterine neoplasms, especially in cases which are diagnostically challenging by conventional techniques.
