Abstract
Atypical polypoid adenomyoma (APA) is a polypoid biphasic lesion of low malignant potential that arises in the lower uterine segment and uterine corpus. The diagnosis of APA is often challenging on biopsy and curettage specimens, and both benign and malignant processes need to be considered in the differential. Stromal expression of p16 and SATB2 have recently been shown to distinguish APA from myoinvasive endometrioid carcinoma. The authors hypothesized that p16 and SATB2 immunohistochemistry could also aid in the distinction of APA from benign adenomyomatous polyp and endometrioid adenomyoma. The study comprised 10 APAs, 7 adenomyomatous polyps, 11 endometrioid adenomyomas, and 10 myoinvasive endometrioid carcinomas. The majority of APAs showed moderate to strong, diffuse p16 and stromal expression. However, most adenomyomatous polyps and endometrioid adenomyomas also exhibited moderate to strong, focal to diffuse p16 stromal expression. SATB2 showed weak to moderate, focal to diffuse expression in the majority of APAs, adenomyomatous polyps and endometrioid adenomyomas. In contrast, p16 and SATB2 were negative to weak and focal in 90% of myoinvasive endometrioid carcinomas. Our findings demonstrate that p16 and SATB2 may be helpful in the differential diagnosis of myoinvasive endometrioid carcinoma and APA while not useful in separating APA from adenomyomatous polyp and endometrioid adenomyoma.

Abstract
PURPOSE To investigate clinicopathological differences between typical endometrial polypoid adenomyomas (TPAs) and endometrial polyps (EPs) and to determine the risk factors and recurrence of TPA and further clarify the pathogenesis and treatment of TPA. METHODS We reviewed the medical records of 488 women with TPA and 500 women with EP. Then, we analyzed the clinical features and manifestations, ultrasonic manifestations, hysteroscopic morphology, and pathological results. In addition, 360 cases of TPA and 367 cases of EP were followed up for 22-77 months and the risk factors TPA recurrence were assessed. RESULTS We detected significant differences in age, menopausal status, body mass index (BMI), the number of pregnancies, and parity between the two groups (P < 0.05). Hysteroscopy revealed that the incidence of polyps > 3 cm in diameter and multiple polyps in the TPA group was significantly higher than that in the EP group (P < 0.01). In addition, the rate of recurrence in the TPA group was significantly higher than that in the EP group (P < 0.05). Over three pregnancies, menopause, curettage, and the application of polyp clamps were all identified as independent risk factors for the recurrence of TPA (P < 0.05). CONCLUSION In addition to high estrogen levels, endometrial injury was identified as the main contributor to TPA pathogenesis. Hysteroscopic electrotomy was identified as the preferential treatment for TPA to avoid recurrence, especially in women with risk factors. Increasing the depth of ablation may prevent the recurrence of TPA more efficiently.

Abstract
Objective: Adenomyosis is a common gynecological disease, which occurs in women in reproductive age and is characterized by the presence of endometrial glands and stroma within the myometrium. Abnormal uterine bleeding, pelvic pain as well as infertility can be associated with adenomyosis. There are two main types of adenomyosis: diffuse and focal. Previously, adenomyosis was diagnosed only upon histopathological examination after hysterectomy and/or adenomyomectomy. However, the development of imagining techniques such as transvaginal ultrasound and magnetic resonance imaging enables the diagnosis of adenomyosis (diffuse and focal) without any surgical intervention. When medical therapy is contraindicated or ineffective, or if patients have a fertility desire, a surgical treatment may be necessary.Methods: In this study, a total of 13 patients with 16 areas of focal adenomyosis were treated. All patients provided their informed consent to undergo transcervical adenomyosis ablation treatment with the Sonata System, aware that the safety and effectiveness of transcervical radiofrequency (RF) ablation for the treatment of adenomyosis has not been established. Follow-up was performed six months after Sonata treatment.Results: The positive results relating to the improvement of symptoms and reduction of adenomyosis lesion size were observed in our study.Conclusion: Transcervical RF ablation with the Sonata System may be a promising therapeutic alternative method to conventional procedures such as hysterectomy for the treatment of focal adenomyosis, disease which has limited therapeutic approach, and may enable a minimally invasive, uterine preserving option.

Abstract
A variety of endometrial lesions may contain mucinous cells. Herein, the author reviews the literature on the classification and clinicopathologic significance of uterine corpus proliferations with a significant mucinous component, assesses the 2020 World Health Organization classification of such lesions, and presents a diagnostic framework. The key epithelial mucinous lesions include mucinous metaplasia, atypical mucinous glandular proliferation and mucinous carcinoma. Each of these categories are classifiable into "usual" and gastrointestinal subtypes, the latter being indicative of intestinal (presence of goblet cells) and/or gastric-type (abundant, pale eosinophilic or clear cytoplasm and well-defined cell borders) morphology. It has been proposed that at least focal expression of gastrointestinal immunohistochemical markers be required for all gastrointestinal type lesions, and for gastrointestinal type atypical mucinous glandular proliferation and carcinoma, minimality or absence of estrogen receptor expression, and the absence of an endometrioid component. Mucinous carcinomas of the usual type, in which >50% of the tumor is comprised of a mucinous component, are the most common. Morphologic subtypes include mucinous carcinoma with microglandular features and mucinous carcinoma with signet rings (signet ring carcinoma). Endometrioid carcinomas with a less than a 50% mucinous component are classified as endometrioid carcinoma with mucinous differentiation. Several studies have directly compared endometrioid and mucinous carcinomas, the latter presumably of the usual type, with respect to patient outcomes after treatment. All have found no difference in overall and disease free survival between these groups. However, three major studies have found mucinous carcinomas to be associated with a higher risk of lymph node metastases. Nineteen cases of mucinous carcinoma of the gastrointestinal type have been reported, and the limited data on their follow-up after primary treatment suggests that this subtype is more clinically aggressive and should accordingly be classified separately from mucinous carcinomas of the usual type. The morphologic spectrum of mucinous carcinoma of the gastrointestinal type is unclear and continues to evolve. Mucinous change, which may sometimes be extensive, may also be associated with papillary proliferation of the endometrium, adenomyoma of the endocervical type, atypical, and typical adenomyomas. In a curettage or biopsy, intestinal type mucinous epithelium may be indicative of any of the gastrointestinal lesions mentioned above, but may also represent samplings of uterine teratomas, yolk sac tumors, genital and extragenital adenocarcinomas with intestinal differentiation, or low-grade appendiceal mucinous neoplasms that secondarily involve the endometrium.

Abstract
Adenomyoma of the cervix is a rare, benign lesion. It is a localized form of adenomyosis, which is surrounded by a benign muscle proliferation forming a tumor similar to leiomyoma. Of the three histological variants of adenomyomas, the most frequent is the endocervical type. We present a case of a 34-year-old woman with a tumor in the lower uterine segment which enlarged during pregnancy, replacing the entire cervix and resulting in the occlusion of the endocervical canal. Ultrasound and tomography showed a mixed tumor pushing aside the uterus and bladder. Speculoscopy revealed that the tumor protruded towards the vaginal canal. Histopathological established the diagnosis of a cervical adenomyoma of the endometrioid type.

Abstract
Diffuse adenomyosis, focal adenomyosis, ovarian endometrioma, superficial endometriosis and deep infiltrating adenomyosis are all defined by the presence of an endometrioid tissue in an ectopic location that is at distance from the endometrium. Although frequently associated, these lesions represent different clinico-pathological entities that the pathologist should recognized. Herein, we review the clinical and pathological features of these entities, as well as related current physiopathological understandings and differential diagnoses that could be raised by some morphological variants. The statistical association between endometriosis and several ovarian tumors, mainly endometrioid and clear cell carcinomas and seromucinous borderline tumors is well established and we present some molecular and morphological features that support this transformation potential.

Abstract
We evaluated the clinicopathologic features of 6 adenomatoid tumors of the uterus with unusual features. All the tumors differed grossly from the usual adenomatoid tumor, typically being ill-defined and occupying >50% of the myometrium, essentially replacing it in 4. The neoplasm extended to the endometrium in 2 cases and in one of these it formed an intracavitary mass; in both the tumor was first diagnosed in a curettage. In the other 4 cases, the adenomatoid tumor was discovered in a hysterectomy specimen performed for irregular vaginal bleeding (3 patients), and the finding of a pelvic mass on a computed tomography scan in a patient with right lower quadrant pain. The tumors extended to the uterine serosa in the form of small grape-like vesicles or cysts in 4 cases. All tumors contained the typical small often irregularly shaped spaces but also had prominent cysts. When cysts involved the serosa, the microscopic appearance mimicked that of peritoneal inclusion cysts. In one case with serosal involvement, a prominent papillary pattern was also present. The cysts were typically closely packed with minimal intervening stroma but were occasionally separated by conspicuous smooth muscle bundles. The stroma in one case was extensively hyalinized. Two tumors were focally infarcted. A striking, but minor, solid growth in which the tumor cells were arranged in tightly packed nests or interanastomosing cords and trabeculae was seen in 2 tumors. The unusual gross and microscopic features of these tumors can cause significant diagnostic difficulty and bring into the differential diagnosis entities that are usually not realistic considerations. The presentation of 2 tumors in a curettage specimen represents an unusual clinical aspect.

A Detailed Study in Adenomyosis and Endometriosis: Evaluation of the Rate of Coexistence Between Uterine Adenomyosis and DIE According to Imaging and Histopathology Findings. Reprod Sci 2021; 28:2387-2397.

Abstract
The current study was designed to evaluate the relationship between adenomyosis and its subtypes with endometriotic lesions (ovarian endometrioma (OMAs) and posterior deep infiltrative endometriosis (DIE)), to examine the probability of existence of a common cause of these mysterious diseases, and to evaluate the accuracy, sensitivity, and specificity of both transvaginal ultrasonography (TVS) and MRI in diagnosis of adenomyotic uterus. In this retrospective cross-sectional study, we selected 154 women with coexistence of endometriosis and adenomyosis according to their imaging, intraoperative, or pathological findings who were nominated for laparoscopic surgery. Eighty-six patients with just DIE resection without LH (laparoscopic hysterectomy) (group 1), and 68 patients with LH + DIE resection (group 2). The accuracy, sensitivity, and specificity of ultrasonographic and MRI findings for diagnosing adenomyosis were 72.1%, 77.6%, 40.0% and 49.2%, 41.5%, 90.0% respectively. So, TVS is a more sensitive diagnostic tool for diagnosing adenomyosis. However, MRI was more specific than TVS in the diagnosis of diffuse adenomyosis especially with simultaneous presence of uterine leiomyoma. Regarding the association of different types of adenomyosis (focal and diffuse) with different endometriosis lesions (OMA and posterior compartment DIE), we just found diffuse type of adenomyosis more frequent in the absence of rectal and rectovaginal septum (RVS) DIE (p ≤ 0.05). In addition to the questionable different nature of rectal and RVS DIE lesion, there is no relationship between adenomyosis subtypes and endometriotic lesions.

Abstract
Adenomyoma of the uterus is a biphasic nodular lesion composed of a mesenchymal component with smooth muscle differentiation and a glandular epithelium. The neoplastic nature of uterine adenomyomas has been controversial because some are considered to be nodular adenomyosis. MED12 mutations are involved in the pathogenesis of uterine smooth muscle tumors (leiomyomas and leiomyosarcomas) and biphasic tumors of the breast (fibroadenomas and phyllodes tumor). To investigate the histogenesis of uterine adenomyomas, we performed pathological and genetic analyses, including Sanger sequencing of MED12. In total, 15 cases of uterine adenomyomas were retrieved and assessed for clinicopathological factors. Immunohistochemistry for smooth muscle actin, desmin, and CD10 was performed. Exon 2 of MED12 was Sanger sequenced using DNA obtained by macrodissection of the adenomyomas. For cases that were positive for somatic MED12 mutations, we next performed microdissection of the mesenchymal and epithelial components. The DNA extracted from each component was further analyzed for MED12 mutations. MED12 mutations were detected in two adenomyomas (2/15, 13%), all in a known hot spot (codon 44). In both lesions, MED12 mutations were detected in multiple spots of the mesenchymal component. The epithelial component did not harbor MED12 mutations. The relatively low frequency of MED12 mutations suggests that not all adenomyomas are leiomyomas with entrapped glands. However, the results of our study suggest that a subset of uterine adenomyomas are true mesenchymal neoplasms.

Abstract
Background Sex cord-like elements are rarely observed in uterine lesions, but these morphological patterns could appear in a variety of uterine tumors and non-tumorous lesions. In this review, we collected the literatures regarding the uterine tumorous and non-tumorous lesions containing sex cord-like elements and summarized these lesions in terms of clinicopathological, immunohistochemical, and molecular features in order to further understand these lesions and provide some new ideas for differential diagnosis. Main body This section provides a comprehensive overview of the clinicopathological, immunohistochemical, and molecular features of uterine lesions with sex cord-like architectures including uterine tumors resembling ovarian sex cord tumors, endometrial stromal tumors, adenomyosis, endometrial polyps, leiomyoma, epithelioid leiomyosarcoma, adenosarcoma, sertoliform endometrioid carcinoma, corded and hyalinized endometrioid carcinoma, mesonephric adenocarcinoma, and mesonephric-like adenocarcinoma. The differential diagnosis based on morphology, immunohistochemistry, and molecular alterations has also been discussed. Conclusion The sex cord-like areas in these lesions show heterogeneous but similar morphological features. Additionally, immunohistochemical staining plays a limited role in differential diagnosis. Furthermore, it is of significance for pathologists to better understand these lesions in order to avoid confusion and mistakes during pathological diagnosis, especially in a biopsy/curettage specimen.

Abstract
OBJECTIVE: This study aimed to assess the efficacy of MRI for differentiating between uterine submucosal polypoid adenomyomas (PAs) and endometrial polyps (EPs). METHODS: MRI was used to examine 40 histopathologically confirmed benign polypoid endometrial tumors (8submucosal PAs and 32 EPs). Atypical PAs were excluded from this study. Quantitative measurements (maximum tumor diameter, maximum cyst diameter, number of cysts, and apparent diffusion coefficient values) and qualitative imaging findings (predominance of cystic or solid components as well as presence of cysts, hemorrhage, myometrial invasion, fluid-fluid level, and fibrous core) were correlated with the two pathologies. RESULTS: The predominance of cystic components (37% vs 6%; p < 0.05) was more frequently observed in PAs than in EPs. The frequency of cysts (88% vs 25%; p < 0.01), hemorrhage (50% vs 9%; p < 0.05), and myometrial invasion (25% vs 0%; p < 0.05) were significantly higher in PAs than in EPs. No significant differences were observed in terms of the maximum tumor diameter, maximum cyst diameter, number of cysts, apparent diffusion coefficient values, and presence of fluid-fluid level and fibrous core between PAs and EPs. CONCLUSION: The differences of MR findings with emphasis on cystic components and hemorrhage may be useful for differentiating between PAs and EPs. ADVANCES IN KNOWLEDGE: The predominance of cystic or solid components and the presence of cysts, hemorrhage, and myometrial invasion were useful MR findings for differentiating between PAs and EPs.

Abstract
We report a 44 year old previously healthy premenopausal woman who presented with a three month history of vaginal bleeding and a 5 cm vaginal mass obscuring the cervix on physical examination. Ultrasound evaluation was non diagnostic. Pelvic MRI demonstrated a 6 cm soft tissue mass in the vagina prolapsed from the uterine cavity with a visible connecting stalk, which is termed the broccoli sign. The initial radiological differential diagnosis included prolapsed uterine malignancy or leiomyoma. Surgical pathology revealed a polypoid adenomyoma. We conclude polypoid adenomyoma should be included in the differential diagnosis for prolapsed uterine tumor demonstrating the broccoli sign.

Abstract
Adenomyosis is defined as the presence of ectopic endometrial glands and stroma within the myometrium. It is a disease of the inner myometrium and results from infiltration of the basal endometrium into the underlying myometrium. Transvaginal ultrasonography (TVUS) and magnetic resonance imaging (MRI) are the main radiologic tools for this condition. A thickness of the junctional zone of at least 12 mm is the most frequent MRI criterion in establishing the presence of adenomyosis. Adenomyosis can appear as a diffuse or focal form. Adenomyosis is often associated with hormone-dependent lesions such as leiomyoma, deep pelvic endometriosis and endometrial hyperplasia/polyps. Herein, we illustrate the MRI findings of adenomyosis and associated conditions, focusing on their imaging pitfalls. TEACHING POINTS • Adenomyosis is defined as the presence of ectopic endometrium within the myometrium. • MRI is an accurate tool for the diagnosis of adenomyosis and associated conditions. • Adenomyosis can be diffuse or focal. • The most established MRI finding is thickening of junctional zone exceeding 12 mm. • High-signal intensity myometrial foci on T2- or T1-weighted images are also characteristic.

Abstract
Among uterine structural abnormalities, myomas and adenomyosis represent two distinct, though frequently coexistent entities, with a remarkable prevalence in women of reproductive age. Various mechanisms have been proposed to explain the impact of each of them on reproductive outcome. In respect to myomas, current evidence implies that submucosal ones have an adverse effect on conception and early pregnancy. A similar effect yet is not quite clear and has been suggested for intramural myomas. Still, it seems reasonable that intramural myomas greater than 4 cm in diameter may negatively impair reproductive outcome. On the contrary, subserosal myomas do not seem to have a significant impact, if any, on reproduction. The presence of submucosal and/or large intramural myomas has also been linked to adverse pregnancy outcomes. In particular increased risk for miscarriage, fetal malpresentation, placenta previa, preterm birth, placenta abruption, postpartum hemorrhage, and cesarean section has been reported. With regard to adenomyosis, besides the tentative coexistence of adenomyosis and infertility, to date a causal relationship among these conditions has not been fully confirmed. Preterm birth and preterm premature rupture of membranes, uterine rupture, postpartum hemorrhage due to uterine atony, and ectopic pregnancy have all been reported in association with adenomyosis. Further research on the impact of adenomyosis on reproductive outcome is welcome.

Abstract
We present a novel case of a 48-yr-old female with a uterine adenomyoma with an unusual pseudoinvasive growth pattern displaying full-thickness penetration beyond the serosal surface in association with a dehisced Caesarian scar. Before hysterectomy, magnetic resonance imaging findings showed an infiltrative lesion suggestive of endometrial carcinoma. An endometrial biopsy was benign but definitive operative management was pursued given the concerning imaging. Gross examination of the uterus demonstrated a 7.2 cm, relatively well-circumscribed polypoid neoplasm with pushing borders extending through the full thickness of the myometrium. A serosal defect with protruding red tissue was noted where the neoplasm penetrated the exterior surface of the uterus. Histologic examination demonstrated benign endometrial glands, associated endometrial stroma, thick-walled vessels, and a prominent smooth muscle component consistent with an adenomyoma. To our knowledge, this unique presentation of a pseudoinvasive adenomyoma extending beyond the serosa is extremely rare and is the first time reported in the literature.

Abstract
Müllerian adenosarcomas usually arise as polypoid masses in the endometrium of post-menopausal women. Occasionally, these tumors arise in the cervix, vagina, broad and round ligaments, ovaries and rarely in extragenital sites; these cases are generally associated with endometriosis. We experienced a rare case of extraendometrial, intramural adenosarcoma arising in a patient with adenomyosis. A 40-year-old woman presented with sudden-onset suprapubic pain. The imaging findings suggested leiomyoma with cystic degeneration in the uterine fundus. An ill-defined ovoid tumor with hemorrhagic degeneration, measuring 7.5 cm in diameter, was detected. The microscopic findings showed glandular cells without atypia and a sarcomatous component with pleomorphism and high mitotic rates. There was no evidence of endometrial origin. To recognize that adenosarcoma can, although rarely, arise from adenomyosis is important to avoid overstaging and inappropriate treatment.

Abstract
This case report presents a 66-year-oId postmenopausal woman with a case of endometrial adenomyomatous polyp (EAP) that presented as postmenopausal vaginal bleeding and mimicked endometrial cancer. The ultrasonography revealed a mildly enlarged uterus approximately 7.1 cm × 3.7 cm in size. The endometrium was 1.9 cm in diameter. The findings of magnetic resonance image (MRI) comprised abnormal intrauterine lesions with multiloculated cystic components. Endometrial biopsy by Pipelle was performed, and revealed hematoma. The hysteroscopy was then arranged, and two polypoid tumors were found. Tumor resection was performed, and the histology of the tumor was adenomyoma. EAP is a rare benign tumor of the uterus that is not easy to differentiate from endometrial cancer by ultrasound or MRI. Hysteroscopy is recommended when the results of tissue sampling by Pipelle differ from the image findings.

An unusual case of uterine cotyledonoid dissecting leiomyoma with adenomyosis. Diagn Pathol 2016; 11:69.

Abstract
Background Cotyledonoid dissecting leiomyoma is a rare variant of uterine smooth muscle tumor with an unusual growth pattern that shows intramural dissection within uterine myometrium and often a placenta-like appearance in its extrauterine components. Case presentation We present a unique case of cotyledonoid dissecting leiomyoma with adenomyosis. A 40-year-old Japanese female presented with prolonged menorrhagia and severe anemia. She had a pelvic mass followed-up for 6 years with a diagnosis of leiomyoma. However, increase in tumor size and cystic changes with hemorrhage were found by magnetic resonance imaging, and total abdominal hysterectomy with bilateral salpingectomy was performed. Macroscopically, the placenta-like exophytic mass protruding from the posterior uterine wall was composed of multiple nodules containing numerous hemorrhagic cysts. The mass showed continuity as a white multinodular dissecting mass infiltrating the posterolateral myometrium. Microscopically, both extra–and intrauterine portions of the mass were composed of nodules that contained swirled neoplastic smooth muscle cells with marked hyalinized degeneration, as observed in cotyledonoid dissecting leiomyomas of conventional type. In addition, numerous non–neoplastic glands of endometrial type surrounded by abundant endometrium–like stromal cells and non–neoplastic smooth muscle cells were found in the tumor, suggesting that it involved a part of concomitant adenomyosis originating from the nontumoral myometrium. Conclusions Thus far, over 30 cases of cotyledonoid dissecting leiomyoma have been reported, none of which have described the presence of adenomyosis within the tumor. The present case suggested that cotyledonoid dissecting leiomyoma might have a unique clinical presentation involving concomitant uterine adenomyosis. It is critical for pathologists, gynecologists, and radiologists to be cognizant of cotyledonoid dissecting leiomyoma variants for timely and appropriate diagnosis and treatment.

Abstract
Rare cases of metastasis to uterine polyps have been reported in English literature but not, to the best of our knowledge, to uterine adenomyomas. All these cases are represented by breast cancer, most of them involving tamoxifen-associated polyps. We first report a case of cutaneous malignant melanoma metastatic to uterine adenomyoma. A computed tomography scan did not reveal any further evidence of disease, suggesting that this metastatic localization may represent something more than a fortuitous case. Based on these observations it is suggested that a subset of malignant melanoma and breast cancer cells share a sort of “homing” phenomenon to polypoid lesions of uterus, due probably to the presence of some chemokines and their specific receptors. Pathologists should be aware of this possibility in order to look carefully for metastatic implants in similar lesions. It is proposed that chemokine profile of neoplastic cells can be a useful tool in predicting metastatic targets.

Abstract
The aim of this study was to perform an immunohistochemical comparison of uterine tumour resembling ovarian sex cord-stromal tumour (UTROSCT) and other uterine lesions with sex cord-like (SCL) differentiation. Six UTROSCTs and 10 potential histological mimics with focal SCL elements were examined, the latter comprising three endometrial stromal nodules, three low-grade endometrial stromal sarcomas, three Müllerian adenosarcomas, and one case of adenomyosis. All cases were stained immunohistochemically for SF1, FOXL2, calretinin and inhibin, and for the less specific markers smooth muscle actin, desmin, CD10, CD56, CD99, cytokeratin, oestrogen receptor and progesterone receptor. Three, four, six and three UTROSCT expressed SF1, FOXL2, calretinin and inhibin, respectively. However, calretinin staining was focal (≤50% cells positive) in five of the cases. Three potential histological mimics demonstrated calretinin, FOXL2 and/or inhibin staining but none was SF1 positive. Most cases in both groups expressed the less specific immunomarkers. SF1 and FOXL2 immunoreactivity in UTROSCT further supports the concept that these tumours demonstrate genuine sex cord-stromal differentiation. While calretinin was the most sensitive UTROSCT marker, staining was usually focal and expression was also seen in two of 10 potential histological mimics. SF1 staining was 100% specific for UTROSCT in this series but this finding should be confirmed in larger studies.

Abstract
The current 2014 World Health Organization (WHO) Classification of mixed epithelial and mesenchymal tumours of the uterus includes categories of carcinosarcoma, adenosarcoma, adenofibroma, adenomyoma and atypical polypoid adenomyoma, the last two lesions being composed of an admixture of benign epithelial and mesenchymal elements with a prominent smooth muscle component. In this review, each of these categories of uterine neoplasm is covered with an emphasis on practical tips for the surgical pathologist and new developments. In particular, helpful clues in the distinction between carcinosarcoma and dedifferentiated endometrial carcinoma will be discussed. In addition, salient features to help distinguish between adenofibroma, adenosarcoma, embryonal rhabdomyosarcoma and other mesenchymal neoplasms in the differential diagnosis will be outlined. Finally, a discussion of adenomyoma and its main differential diagnostic considerations will be covered.

Abstract
We describe a case of giant cystic uterine adenomyoma that was diagnosed and treated by hysteroscopy. In a 27-year-old woman with menometrorrhagia, severe dysmenorrhea, and chronic pelvic pain, pelvic ultrasonography revealed an enlarged uterine cavity filled with homogeneous low echogenic fluid content. A large cornual hematometra of 8.0 cm in diameter in a bicornuate uterus was suspected, and this hypothesis was also supported by magnetic resonance imaging findings. On the contrary, hysteroscopy revealed a bilocular huge cystic lesion of the posterior uterine wall that was removed by means of monopolar loop resection. The operative finding and the histopathologic examination confirmed the diagnosis of cystic adenomyoma of the uterus. Hysteroscopy may represent a valid tool for diagnosis and minimally invasive treatment of cystic adenomyoma, including those of large volume. Its use is helpful in differential diagnosis between cystic adenomyoma and uterine malformations as a possible cause of pelvic pain.

Abstract
PURPOSE Polypoid adenomyoma (PA) is an uncommon benign tumor of the uterus appearing as a submucosal polypoid mass, or rarely as a subserosal polypoid mass. PA should be differentiated from atypical polypoid adenomyoma or malignant uterine tumors. The purpose of our case series is to evaluate magnetic resonance (MR) manifestations of PA for the differential diagnosis. METHODS Seven cases with surgically proven PA, five submucosal, and two subserosal, were evaluated. MR imaging findings including contrast enhancement in six cases (four cases with dynamic contrast-enhanced MR study), diffusion-weighted imaging (DWI) in five cases, and susceptibility weighted imaging (SWI) in two cases were retrospectively reviewed. RESULTS All seven lesions exhibited isointensity compared with the myometrium and 4 of 7 lesions (57%) contained high signal intensity hemorrhagic areas on T1-weighted images. On T2-weighted images, signal intensity was variable and all seven lesions contained cysts. None of five lesions with DWI exhibited high signal intensity compared with the normal myometrium. All six lesions showed intense contrast enhancement similar to that of the myometrium on post-contrast T1-weighted images. Punctate low intensity areas reflecting blood contents were revealed in all two lesions with SWI. CONCLUSIONS Submucosal or subserosal polypoid masses containing hemorrhagic areas, and cysts reflecting functional endometrium and dilatation of endometrial glands are suggestive for PA. Intense contrast enhancement similar to that of the myometrium may be another characteristic finding for PA.

Abstract
Purpose Exogenic adenomyoma of the cervix is very rare. To date, very few cases have been reported, and the presentation and diagnosis are not clear. The aim of this study was to present 2 cases of exogenic adenomyoma of the cervix and summarize what is known about this disease by conducting a literature review of reported findings. Methods The clinical data from 2 cases of women with exogenic adenomyoma of the cervix admitted to Peking University First Hospital were analyzed retrospectively, and a systematic literature review was carried out. Results In our cases, exogenic adenomyoma of the cervix presented as a mass with mixed solid and cystic lesions in the pelvis and could not be separated from the cervix. Postoperative examination of the surgical specimen using pathological tests confirmed the tumors were composed of a proliferation of endocervical glands and smooth muscle, based on which exogenic adenomyoma of the cervix was confirmed. Conclusions Exogenic adenomyoma of the cervix should be considered in the diagnosis, in cases of mixed solid and cystic pelvic masses found in close relationship with the cervix.

Abstract
Uterine adenomyoma is often overlooked, and cervical adenomyoma is extremely rare. Previous reports suggest that a uterine adenomyoma usually occurs in the uterine corpus but rarely in the uterine cervix. Approximately 20 reports of cervical adenomyoma have been published to date. However, cervical adenomyoma has been rarely investigated using magnetic resonance imaging. We encountered a large multicystic tumor in the uterine cervix of a 26-year-old woman that was difficult to diagnose preoperatively. On the basis of cytology, biopsy, and imaging findings, the cervical multicystic tumor measured approximately 13.0 cm. The patient underwent vaginal adenomyomectomy, and the tumor was completely resected. A histologic diagnosis of cervical adenomyoma was made because of proliferation of endocervical glands and the presence of rounded smooth muscle stroma. Awareness of this tumor in the uterine cervix is important for accurate diagnosis and treatment. Herein we present a rare case of a large cervical adenomyoma, with imaging studies, an image of the operation, histologic findings, and a literature review.

Abstract
Atypical polypoid adenomyoma (APA) is an uncommon polypoid lesion of the uterus. To clarify the mechanism of its histogenesis, we examined the functional role of β-catenin, with reference to expression of p21(waf1), cyclin D1, cyclin E, CD10, and α-smooth muscle actin (SMA), as well as cell proliferation, in 7 lesions. In the epithelial components, expression of nuclear β-catenin, p21(waf1), and cyclin D1 was increased in a stepwise fashion from normal tissue through complex atypical hyperplasia and adenomyoma to APA lesions, particularly in squamous morular areas, whereas cell proliferation, as well as cyclin E expression, was significantly decreased in the latter. Similar findings were evident in the stromal lesions, with the exception of a case of nuclear β-catenin. In addition, coexpression of CD10 and α-SMA markers was observed in the stromal components in 3 APA cases, in line with the results of normal secretory endometrial and adenomyoma samples, suggesting that cells progress to myofibromatous cells in response to differentiation-promoting events. Finally, β-catenin gene (CTNNB1) mutations were detected in all APA cases, the single nucleotide substitutions being in the epithelial but not the stromal components. These findings suggest that activation of β-catenin signaling, probably secondary to the gene abnormalities, plays an important role in the formation of the complex epithelial architecture in APAs, leading to inhibition of cell proliferation through overexpression of p21(waf1). In contrast, changes in the stromal cell phenotype may occur through a shift from CD10 to α-SMA immunopositivity, independent of CTNNB1 status.

Abstract
A minor component of smooth muscle may be present in the stroma of benign endometrial polyps and 2 distinctive endometrial polypoid lesions, atypical polypoid adenomyoma and adenomyoma, are characterized by stroma with a predominant smooth muscle component. In this report, we describe 2 unusual endometrial polyps in 43- and 60-year-old women in which the stromal component was predominantly composed of smooth muscle with an epithelioid appearance, a phenomenon which, as far as we are aware, has not been previously reported.

Value of magnetic resonance imaging in diagnosis of adenomyosis and myomas of the uterus. J Minim Invasive Gynecol 2013; 19:620-6. [PMID: 22935303 DOI: 10.1016/j.jmig.2012.06.003] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2012] [Revised: 06/14/2012] [Accepted: 06/21/2012] [Indexed: 11/23/2022]
Abstract
STUDY OBJECTIVE To estimate the diagnostic performance of magnetic resonance imaging (MRI) in detection of myomas and adenomyosis of the uterus. DESIGN Prospective cohort observational study (Canadian Task Force classification II-2). SETTING Department of obstetrics and gynecology, tertiary academic hospital. PATIENTS One hundred fifty-three consecutive women with an enlarged uterus accompanied by gynecologic symptoms and/or with an asymptomatic pelvic mass. INTERVENTION Total abdominal hysterectomy. All patients underwent MRI before the operation. MEASUREMENTS AND MAIN RESULTS The sensitivity, specificity, positive, and negative predictive value of MRI for the diagnosis of uterine pathology was calculated using histologic findings as the standard criterion for final diagnosis. Receiver operating characteristics curves were constructed to describe the diagnostic performance of MRI. In the diagnosis of myomas, MRI demonstrated sensitivity of 94.1%, specificity of 68.7%, PPV of 95.7%, and NPV of 61.1%. In the diagnosis of adenomyosis, MRI demonstrated sensitivity of 46.1%, specificity of 99.1%, PPV of 92.3%, and NPV of 88.5%. The area under the curve (AUC) for the diagnostic performance of MRI in the detection of myomas and adenomyosis was 0.81 and 0.73, respectively. Uterine sarcoma was diagnosed in 5 patients; in these cases, MRI demonstrated sensitivity of 60.0%, specificity of 99.2%, PPV of 75.0%, and NPV of 98.4%. The AUC for MRI in the diagnosis of uterine sarcomas was 0.80. CONCLUSIONS MRI exhibits a high AUC for the diagnosis of both adenomyosis and myomas. The PPV of MRI in the diagnosis of adenomyosis and myomas of the uterus is high as well. MRI seems to be a useful technique in everyday clinical practice in the diagnostic approach of these common conditions, enabling clinicians to select the most appropriate management.

Abstract
Müllerian adenosarcomas most commonly arise in the uterine corpus from the eutopic endometrium. Occasionally, they arise in the cervix, vagina, broad and round ligaments, and ovaries and rarely in extragenital sites, usually in association with endometriosis. The authors report a rare case of extraendometrial, intramural adenosarcoma of low grade arising from a subserosal adenomyoma in a 46-year-old woman who presented with vaginal bleeding. No evidence of eutopic endometrial origin was identified; the adenosarcoma showed only limited myometrial invasion and no serosal involvement. Because of its subserosal location, the tumor would be overstaged as IC (deeply myoinvasive) in the new FIGO staging system. Stage IC tumors would normally be considered for adjuvant treatment, which would be inappropriate in this case. To avoid overstaging and inappropriate treatment, it is important to recognize that adenosarcoma can, rarely, arise in adenomyomas (or adenomyosis).

Abstract
Uterine adenosarcomas are uncommon mixed Müllerian neoplasms, most commonly arising in the uterine corpus. A new Federation of International Gynecologic Organization staging system for these tumors has recently been implemented. This staging system is an improvement on the earlier generic application of the 1988 Federation of International Gynecologic Organization staging system for endometrial cancer to adenosarcoma. Herein, we report 3 uterine adenosarcomas with unusual features. For 2 of these, no specific staging guidelines are provided by either the earlier or, more importantly, the new staging system. The first case is of an adenosarcoma arising in the eutopic endometrium with involvement of underlying adenomyosis without myometrial invasion; the second originated in a mural adenomyoma in the absence of eutopic endometrial involvement; and the third case encompassed synchronous endometrial and extrauterine (peritoneal) neoplasms. Such cases are rare, and there is insufficient evidence to be definitive about staging. Thus, we suggest a descriptive reporting strategy for adenosarcomas with these unusual features. We also propose a reporting nomenclature for such cases to ensure standardization such that they can be adequately recorded in synoptic reporting protocols. This will facilitate reliable data collection such that an evidence-based staging system for these scenarios may be derived.

Abstract
The term 'mixed Müllerian tumour' applies to uterine tumours composed of epithelial and mesenchymal elements of Müllerian origin. These neoplasms are classified into adenomyomas, adenofibromas, adenosarcomas, and carcinosarcomas (malignant Müllerian mixed tumours) based on whether the epithelial and stromal elements are benign or malignant. The rare atypical polypoid adenomyoma usually involves the lower uterine segment and, on curettings, may be confused with invasive adenocarcinoma. Adenosarcomas are low-grade neoplasms classified halfway along the spectrum of mixed Müllerian tumours, with adenofibromas at one end and carcinosarcomas (malignant Müllerian mixed tumours) at the other. Some tumours currently classified as 'adenofibromas' on the basis of their low mitotic count and lack of nuclear atypia are, in fact, well differentiated adenosarcomas. Carcinosarcoma is composed of admixed but distinctive carcinomatous and sarcomatous elements. On the basis of the clonal origin of both tumour components, carcinosarcomas are currently thought to be metaplastic carcinomas rather than uterine sarcomas.

Abstract
Mullerian adenosarcoma is an uncommon, but not rare, mixed tumor containing a neoplastic but benign or mildly atypical epithelial element and a sarcomatous, usually low-grade, stromal component. The most common site is the uterine corpus but adenosarcoma also occurs in the cervix and ovary and more rarely in the vagina, fallopian tube, arising from peritoneal surfaces, or outside the female genital tract, for example in the intestine. Most uterine cases have a polypoid gross appearance, sometimes resulting in the formation of multiple polyps. Characteristic histologic features include a low power "phyllodes-like" architecture with leaf-like projections lined by a variety of benign Mullerian type epithelia, sometimes with squamous metaplasia. Intraglandular stromal protrusions are a characteristic feature. The stroma may be uniformly cellular but there is typically increased cellularity around the epithelial elements, resulting in the formation of a cambium layer. Using the World Health Organization definition, stromal mitotic activity of 2 or more per 10 high-power fields is required for a diagnosis of adenosarcoma but in practice the diagnosis is made with stromal mitotic activity less than this if the characteristic architecture and cambium layer is present. The stromal component is usually morphologically "low-grade" and of endometrial stromal or fibroblastic type (hormone receptor and CD10 positive). Sometimes it is high grade, resembling undifferentiated sarcoma. Additional features sometimes present include heterologous stromal elements or sex cord-like differentiation. Uterine adenosarcomas are, in general, low-grade neoplasms capable of local recurrence after polypectomy or hysterectomy and much less commonly distant metastasis. The 2 most important adverse prognostic factors, which sometimes coexist, are deep myometrial invasion and sarcomatous overgrowth; the latter is usually associated with morphologically "high-grade" stromal elements with loss of expression of hormone receptors and CD10. Adenosarcoma may be confused with a variety of lesions and one of the main differential diagnoses is adenofibroma in which the stromal component is, by definition, morphologically benign. However, occasional adenofibromas recur or even metastasize. As such, it has been suggested that all adenofibromas should be classified as adenosarcomas, albeit with low-malignant potential. Ovarian adenosarcomas are much more likely to exhibit malignant behavior than their uterine counterparts, probably due to the lack of an anatomic barrier to peritoneal dissemination.

Abstract
Smooth muscle tumors of the ovary are rare, and ovarian adenomyoma are even rarer. It is a well-circumscribed biphasic tumor composed of benign glands and smooth muscle cells, as well as a variety of pseudoneoplastic glandular lesion. After extensive literature search, the case presented in this article appears to be the third case of an ovarian adenomyoma and the first case in a postmenopausal woman.
