Inflammatory myofibroblastic tumors (IMT) of the uterus may be underrecognized as their morphology and immunophenotype may overlap with myxoid variants of uterine smooth muscle tumors and endometrial stromal tumors. Although ALK is a helpful biomarker, not all uterine IMTs are ALK-rearranged, and a small subset of myxoid leiomyosarcomas is ALK-positive. Herein, we evaluated a series of 23 IMTs for the novel endometrial stromal markers interferon-inducible transmembrane protein-1 (IFITM1) and BCOR, the novel myoid marker transgelin, and possible predictive markers p16 and p53 by immunohistochemistry to determine their expression profile and potential prognostic value.

Background: Fibroma or leiomyoma is the most common benign tumor of the female reproductive system, which is usually found in the uterus, but may also occur in other places, such as the ovary, the broad ligament, and in rare cases in the abdominal wall. The formation of the abdominal wall leiomyoma may result from the implantation of myometrium tissue following surgical removal of the uterine leiomyoma, but sometimes these masses occur in a person who has no history of myomectomy.

Case Presentation: This case was a patient who became a candidate for laparoscopy due to abnormal uterine bleeding and pain in the right upper quadrant of the abdomen and ovarian mass. Read More

Leiomyomas are classified as benign mesenchymal neoplasms and consist of smooth muscle cells with variable amounts of fibrous stroma. The tumors occur most frequently in the uterus, affecting 20%-30% of women of reproductive age, but vaginal leiomyomas are rare with only around 300 cases reported since the first case was described in 1733. These tumors are thought to arise from Müllerian smooth muscle cells in the subepithelium of the vagina. Read More

Our insights into the molecular pathogenesis of uterine smooth muscle tumors have improved significantly. Accordingly, in the present review, we advocate a more refined risk assessment for patients considering surgical removal of fibroids or hysterectomy, respectively, requiring morcellation. For this procedure, the risk estimates given for the iatrogenic spread of a previously unexpected malignancy considerably vary among different studies. Read More

Atypical polypoid adenomyoma (APA) is a polypoid lesion that is comprised of atypical endometrial glands and fibromuscular stroma, which pathologists often confuse with myoinvasive endometrioid carcinoma. Here, we characterized the immunohistochemical and molecular features of the stromal components of APA to find distinct markers between APA and myoinvasive endometrioid carcinoma. First, we examined the immunohistochemical expression and gene mutations that were previously investigated in uterine and breast fibroepithelial lesions using 12 cases of APA. Read More

Uterine myxoid smooth muscle tumors, including myxoid leiomyosarcoma, are rare and their genomic profile has not been fully characterized. With the discovery of uterine sarcomas with ZC3H7B-BCOR fusion and BCOR internal tandem duplications, the differential diagnosis of myxoid smooth muscle lesions is expanding to include molecularly-defined tumors. Thus, we aimed to explore the genomic landscape of myxoid smooth muscle tumor using comprehensive tools. Read More

Hereditary leiomyomatosis and renal cell carcinoma syndrome (HLRCC), caused by a germline mutation in the fumarate hydratase (FH) gene, predisposes patients to uterine and cutaneous smooth muscle tumors and an aggressive type of renal cell carcinoma. Almost all women with HLRCC develop symptomatic uterine leiomyomas resulting in surgery at young ages, presenting an ideal opportunity for early detection of these patients and the implementation of surveillance measures for renal cell carcinoma. FH-deficient uterine leiomyomas can show characteristic morphologic features (FH-d morphology) that have been previously described. Read More

Extravillous trophoblasts (EVTs) migrate into uterine decidua and induce vascular smooth muscle cell (VSMC) loss through mechanisms thought to involve migration and apoptosis, achieving complete spiral artery remodeling. Long noncoding RNA maternally expressed gene 3 (MEG3) can regulate diverse cellular processes, such as proliferation and migration, and has been discovered highly expressed in human placenta tissues. However, little is known about the role of MEG3 in modulating EVT functions and EVT-induced VSMC loss. Read More

Leiomyomas are prevalent benign smooth muscle tumors in the uterus, displaying variable degrees of FDG uptake on PET/CT. The glucose metabolism intensity of those lesions relies on biologic features and markedly increased FDG accumulation is more typically related to malignant diseases, as in the case of leiomyosarcomas. Notwithstanding that uterine fibroids typically exhibit mild to moderate FDG uptake, in this article we report a case of unexpectedly intense hypermetabolism of a benign uterine leiomyoma on a PET/CT scan performed for initial staging of a breast cancer patient.
