Laparoscopic Treatment of Sclerosing Stromal Tumor of the Ovary in a Woman With Gorlin-Goltz Syndrome: A Case Report and Review of the Literature.

Gorlin-Goltz syndrome is a rare hereditary multisystemic disease. Multiple basal cell carcinomas, odontogenic keratocysts, and skeletal abnormalities are the main clinical manifestations of the syndrome, but several organs can be involved. Moreover, this condition is associated with the development of various benign and malignant tumors, even in the genital tract. This report describes a rare association between Gorlin-Goltz syndrome and the sclerosing stromal tumor of the ovary. Because the ultrasound and magnetic resonance imaging patterns of this tumor can be similar to those of a malignant neoplasm, prompt surgical intervention and histological confirmation of diagnosis is mandatory; however, this is a benign lesion and thus can be approached with a laparoscopic fertility-sparing surgery. Gynecologists should be aware of this possible association to provide appropriate counseling for these women, and to take a fertility-sparing laparoscopic approach whenever possible.

Complex networks of multiple factors in the pathogenesis of uterine leiomyoma.

OBJECTIVE: To summarize the information regarding pathogenetic factors of leiomyoma formation and growth, and to make a simple integrated pathogenetic view of this tumor for further thinking to establish new therapeutic options. DESIGN: PubMed and Google Scholar searches were conducted to identify the relevant studies on pathogenesis of uterine leiomyoma, which are hereby reviewed and discussed. SETTING: Academic medical center. PATIENT(S): Not applicable. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Not applicable. RESULT(S): To date, the pathogenesis of uterine leiomyomas is not well understood. However, genetic alterations (especially MED12 and HMGA2) and involvement of epigenetic mechanisms (DNA methylation, histone modifications, and microRNA) in leiomyoma provide the clue of initiator of this tumor. Estrogens and P are considered as promoters of leiomyoma growth, and growth factors, cytokines, and chemokines are thought to be as potential effectors of estrogens and P. Extracellular matrix components are a major structural part of leiomyoma tissue that are abnormally orientated and can modify mechanical stress on cells, which leads to activation of internal mechanical signaling and may contribute to leiomyoma growth. CONCLUSION(S): Besides many genetics and epigenetic factors, the important link among the sex steroids, growth factors, cytokines, chemokines, and extracellular matrix and their involvement in cell proliferation, fibrotic processes, apoptosis, and angiogenesis are implicating a complex network in leiomyoma formation and growth. Those findings could provide information to establish future therapeutic options for the management of this tumor.
