BACKGROUND: Inactivating mutations of CDC73 cause Hyperparathyroidism-Jaw Tumour syndrome (HPT-JT), Familial Isolated Hyperparathyroidism (FIHP) and sporadic parathyroid carcinoma. We conducted CDC73 mutation analysis in an HPT-JT family and confirm carrier status of the proband's daughter. METHODS: The proband had primary hyperparathyroidism (parathyroid carcinoma) and uterine leiomyomata. Her father and daughter had hyperparathyroidism (parathyroid adenoma) but no other manifestations of HPT-JT...

Benign metastasizing leiomyoma (BML) is a rare disease entity typically presenting as multiple extrauterine leiomyomas associated with a uterine leiomyoma. It has been hypothesized that the extrauterine leiomyomata represent distant metastasis of the uterine leiomyoma. To date, the only molecular evidence supporting this hypothesis was derived from clonality analyses based on X-chromosome inactivation assays. Here, we sought to address this issue by examining paired specimens of synchronous pulmonary and uterine leiomyomata from three patients using targeted massively parallel sequencing and molecular inversion probe array analysis for detecting somatic mutations and copy number aberrations...

The GnRH agonistic analogs enable for desensitizing the hypothalamo-pituitary-gonadal axis in malignant and benign conditions where minimizing the production of sex hormones, or blocking ovulation is necessary. The possible indications are prostate cancer, benign prostate hyperplasia, breast cancer, endometriosis, precocious puberty, uterine leiomyomata, assisted reproduction (ART)/in vitro fertilization (IVF), PCOS, minimizing the gonadotoxic effect of chemotherapy in young women, and possibly ovarian cancer...

BACKGROUND: Hereditary leiomyomatosis and renal cell cancer syndrome (HLRCC) is an autosomal dominant syndrome due to mutation in fumarate hydratase. Patients with HLRCC frequently develop cutaneous and uterine leiomyomata and are at risk for renal cell carcinoma. Rarely, other malignancies have been reported. MAIN OBSERVATIONS: We report the development of basal cell carcinoma and melanoma in two siblings with genetically-confirmed HLRCC. CONCLUSIONS: It is unclear whether the development of melanoma and basal cell carcinoma in our patients is due directly to their mutations in the gene encoding fumarate hydratase, or genetic susceptibility at another unrelated locus, or whether these are incidental lesions...

BACKGROUND: Leiomyosarcomas (LMS) and endometrial stromal sarcomas (ESS) may display overlapping histomorphology, which may challenge diagnostic accuracy. Since LMS and ESS have vastly different clinical behavior and adjuvant therapy recommendations, accurate diagnosis is critical. CASE: We present the case of an 83-year-old female with postmenopausal bleeding who underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy for clinically atypical appearing leiomyomata...

Uterine leiomyomata present major problem for females. Although they are benign tumors their frequency is associated with many symptoms like infertility, abdominal pain, menorrhagia. Authors based on their own morphological studies and review of the literature try to indicate main factors causing angiogenesis within leiomyomata and its influence on tumor growth. The strongest proangiogenic factor seems to be hypoxia, which stimulates up- and down-regulation of numerous genetically determined substances. Also mechanical pressure acting upon newly growing vessels is one of the factors which may determine formation of so called "vascular pseudocapsule" around the lesion...

BACKGROUND: Primary leiomyoma of the ovary is a rare benign ovarian tumor that only seldom causes acute abdomen. CASE SUMMARY: A 35-year-old gravida 1, para 0 woman presented with a history of acute lower abdominal pain, and 10 weeks of amenorrhea. The patient's physical examination revealed abdominal tenderness, defense, and rebound. On ultrasonographic examination, a solid mass measuring 9.3 × 7.8 cm was detected adjacent to the uterine fundus. The mass was preoperatively diagnosed as a twisted pedunculated subserosal uterine myoma...

We previously demonstrated that berberine (BBR) inhibits cell proliferation and induces apoptosis in a human uterine leiomyoma (UtLM) cell line but does not demonstrate a significant cytotoxic effect in a normal human uterine smooth muscle (UtSM) cell line. However, the mechanisms of this inhibition are unclear. Of note, cyclooxygenase 2 (COX2) and pituitary tumor-transforming gene 1 (PTTG1) are overexpressed in human uterine leiomyomata and are involved in the pathogenesis of uterine fibroids (UFs). We found that COX2 and PTTG1 were overexpressed in UtLM and that BBR decreased COX2 and PTTG1 expression in UtLM cells...

Benign metastasizing leiomyoma is a rare diagnosis in women with history of uterine leiomyomata. Distant metastasis may occur anywhere but is most commonly seen to the lungs. The age of presentation is often young to mid age, with patients often having a history of hysterectomy or myomectomy for uterine leiomyomata. The clinical course of these patients is most often indolent. However, the size and number of nodules can result in pulmonary symptoms. Differentiating benign metastasizing leiomyoma from malignant metastatic disease, including from leiomyosarcoma, is important to avoid unnecessary procedures or delayed treatment...

In a retrospective review, we identified six cases of disseminated peritoneal leiomyomatosis (DPL) that occurred after resection for uterine leiomyoma(ta) using a morcellation procedure between 2010 and 2016. DPL occurred in less than 1% of all patients who underwent a prior hysterectomy with morcellation, and DPL never occurred without having underwent such a resection. The median age of women at the time of their original resection of uterine tissue was 38.6 years; the median time interval until resection of DPL after the primary morcellation procedure was 73 months and the median age was 48 years...

Benign metastasizing leiomyoma (BML) is a rare disease that occurs in middle-aged women with a history of uterine myomas. The most common location of BML is the lungs. We report the case of a 44-year-old obese woman (BMI 45.5) who underwent surgery to remove uterine leiomyomata and then continued to take a drug containing the hormone estradiol for a period of 15 years. Computed tomography chest examinations revealed multiple size nodules of varying size in both lungs. Videothoracoscopy and right thoracotomy was performed, and a few nodules were enucleated from each lobe of the right lung...
