Uterine fibroids are common benign tumors originating from the uterus's smooth muscle layer, often leading to symptoms such as pelvic pain, and reproductive issues. Early detection is crucial to prevent complications such as infertility or the need for invasive treatments like hysterectomy. One of the main challenges in diagnosing uterine fibroids is the lack of specific symptoms, which can mimic other gynecological conditions.

Primary Vaginal Leiomyosarcoma Mimicking Bartholin's Cyst.

J Midlife Health

July 2024

Department of Pathology and Laboratory Medicine, AIIMS, Bhubaneswar, Odisha, India.

Leiomyosarcomas (LMS) arise from smooth muscle cells with more predilection to the uterus, abdomen, retroperitoneum, and blood vessels. LMS of vagina is very rare and usually presents in the early stage as an asymptomatic mobile mass with no clinical features of malignancy and gives the appearance of a benign lesion which can easily be mistaken for a Bartholin's cyst or a vaginal fibroid. The chances of metastasis in LMS are high with poor survival rates.

Unlabelled: Most mesenchymal tumors found in the uterine corpus are benign tumors; however, uterine leiomyosarcoma is a malignant tumor with unknown risk factors that repeatedly recurs and metastasizes. In some cases, the histopathologic findings of uterine leiomyoma and uterine leiomyosarcoma are similar and surgical pathological diagnosis using excised tissue samples is difficult. It is necessary to analyze the risk factors for human uterine leiomyosarcoma and establish diagnostic biomarkers and treatments.

Department of Radiation and Medical Oncology, Hubei Key Laboratory of Tumor Biological Behavior, Hubei Cancer Clinical Study Center, Zhongnan Hospital of Wuhan University, Wuhan, China.

Intrauterine adhesion (IUA) is manifestations of endometrial fibrosis and excessive extracellular matrix deposition. C1q/tumor necrosis factor-related protein-6 (CTRP6) is a newly identified adiponectin paralog which has been reported to modulate the fibrosis process of several diseases; however, the endometrial fibrosis function of CTRP6 remains unknown. Our study aimed to assess the role of CTRP6 in endometrial fibrosis and further explore the underlying mechanism.

Uterine leiomyomas, also known as uterine fibroids, are a commonly encountered condition with a diverse clinical presentation. Uterine fibroids are benign, smooth muscle tumors of the uterus arising from a single myometrial cell. The presentation can vary from asymptomatic incidental findings to causing a wide array of gynecological symptoms, including abnormal uterine bleeding, infertility, chronic pelvic pain, and bulk-related symptoms.

Introduction: Leiomyosarcoma (LMS), together with smooth muscle tumors of uncertain malignant potential (STUMP) and benign leiomyomas, belongs to a heterogeneous group of uterine neoplasms. According to the World Health Organization, tumors originating from uterine smooth muscle fibers are the second most frequent tumors. It is challenging to distinguish between STUMP and LMS because of an overlap of symptoms, lack of a precise definition, and unequivocal information obtained using imaging diagnostic methods.

Uterine fibroids, benign tumors originating from uterine smooth muscle cells, vary in prevalence depending on patient ethnicity, hormonal exposure, and genetics. Due to their high incidence, these neoplasms pose a significant burden on healthcare systems. Current treatment strategies range from routine monitoring in asymptomatic cases to surgical procedures such as myomectomy or hysterectomy in symptomatic patients, with an increasing trend toward uterus-preserving or non-surgical alternatives.
