Abstract
Myxoid leiomyosarcoma (MLS) is a rare but well-documented tumor that often portends a poor prognosis compared to the conventional leiomyosarcoma. This rare sarcoma has been reported in the uterus, external female genitalia, soft tissue, and other locations. However, a definite rectal MLS has not been reported. Recently five cases of MLS were reported to harbor PLAG1 fusions (TRPS1::PLAG1, RAD51B::PLAG1, and TRIM13::PLAG1). In this report, we present a case of rectal MLS with a novel MIR143HG::PLAG1 fusion detected by RNA next-generation sequencing.

Mandato VD, Torricelli F, Mastrofilippo V, Palicelli A, Costagliola L, Aguzzoli L. Primary Ovarian Leiomyosarcoma Is a Very Rare Entity: A Narrative Review of the Literature. Cancers (Basel) 2023; 15:cancers15112953. [PMID: 37296915 DOI: 10.3390/cancers15112953] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/18/2023] [Accepted: 05/19/2023] [Indexed: 06/12/2023] Open
Abstract
BACKGROUND Primary ovarian leiomyosarcoma is a very rare malignancy characterized by unclear management and poor survival. We reviewed all the cases of primary ovarian leiomyosarcoma to identify prognostic factors and the best treatment. METHODS We collected and analyzed the articles published in the English literature regarding primary ovarian leiomyosarcoma from January 1951 to September 2022, using PubMed research. Clinical and pathological characteristics, different treatments and outcomes were analyzed. RESULTS 113 cases of primary ovarian leiomyosarcoma were included. Most patients received surgical resection, associated with lymphadenectomy in 12.5% of cases. About 40% of patients received chemotherapy. Follow-up information was available for 100/113 (88.5%) patients. Stage and mitotic count were confirmed to affect survival, and lymphadenectomy and chemotherapy were associated with a better survival rate. A total of 43.4% of patients relapsed, and their mean disease-free survival was 12.5 months. CONCLUSIONS Primary ovarian leiomyosarcomas are more common in women in their 50s (mean age 53 years). Most of them are at an early stage at presentation. Advanced stage and mitotic count showed a detrimental effect on survival. Surgical excision associated with lymphadenectomy and chemotherapy are associated with increased survival. An international registry could help collect clear and reliable data to standardize the diagnosis and treatment.

Abstract
Primary ovarian leiomyosarcomas (POLMs) comprise <0.1 % of all ovarian malignancies. Here we aimed to define the clinical, surgical, and pathological features, as well as the oncologic outcome, of POLM. A systematic review of the medical literature was performed to identify articles about POLMs. An electronic literature search was conducted for English language abstracts of articles published between 1975 and December 2018.51 articles were included in the study. The primary endpoint of the study was disease-free survival (DFS) and overall survival (OS), whereas the secondary endpoint was clinicopathological features. Five-year DFS and OS for the entire cohort was 15 % and 26 %, respectively. The DFS and OS were significantly related to paraaortic lymphadenectomy, a mitotic index>10/high power field, and advanced cancer stages. Eventually, we were unable to obtain clear results, this might be due to the limited number of cases at the literature.With more authors presenting their own cases, it will be possible to have clearer results.

Abstract
Primary ovarian leiomyosarcoma (POLMS) is a rare disease. To the best of our knowledge, only 72 cases, including the present case, have been reported in the English literature, while synchronous POLMS and fibroma in a single ovary have not previously been reported at all. In the present study, a 46-year-old premenopausal woman was diagnosed with a mass in the left ovary in 2005. A total of 5 years after the diagnosis of this mass, the patient was admitted to hospital exhibiting lower abdominal pain, and two masses were observed in the left ovary. An exploratory laparoscopy was performed. Frozen section analysis led to a diagnosis of fibroma. Furthermore, the observed second mass was hypothesized to be a malignant form of the original fibroma. A hysterectomy and bilateral salpingo-oophorectomy were performed. Pathological reports following surgery revealed concurrent stage Ic POLMS and fibroma in the left ovary. A total of 13 months after the initial surgery, recurrent leiomyosarcoma was detected. Although the patient underwent multiple cytoreductive surgeries and chemotherapy cycles, as well as interstitial brachytherapy and conventional therapy, a poor state of health ensued. Due to the rarity of POLMS, particularly in combination with ovarian fibroma, the current report presents a detailed overview of the literature and discusses a number of histogenetic and clinical issues.

Abstract
A 15-year-old, female mixed-breed dog presented with abdominal distention. An exploratory
laparotomy revealed a large left ovarian mass (20 × 15 × 12 cm). Histopathological
examination of the mass revealed a mixed myxoid liposarcoma and a well-differentiated
leiomyoma. Four months after surgical removal of the mass, the dog died due to multiorgan
metastasis. The metastasis was composed solely of the liposarcoma component. The
liposarcoma component was Alcian Blue- and Oil red O-positive, and demonstrated
immunoreactivity with S-100, adipophilin and vimentin. Electron microscopy revealed that
the tumor cell cytoplasms were packed with lipid vacuoles and dilated rough endoplasmic
reticulum. To our knowledge, this is the first report of myxoid liposarcoma and leiomyoma
co-existing in a canine ovary.

Abstract
Primary pure myxoid leiomyosarcoma of the ovary is extremely rare, comprising of only 1% of the ovarian tumours. Patient presented with a mass in the right iliac fossa since three months. Radiological diagnosis of broad ligament fibroid was given. Right salphingo-oophorectomy with enucleation of ischial fossa and wedge biopsy of left ovary was carried out. Based on gross, microscopy and immunohistochemistry a diagnosis of primary myxoid leiomyosarcoma of ovary was made. We report a rare case of primary pure myxoid leiomyosarcoma of the ovary with metastasis to ischial fossa emphasising on reliable prognostic markers. Ovarian leiomyosarcomas are highly aggressive tumours with poor prognosis.

Abstract
Smooth muscle tumors are the most common among mesenchymal tumors in the female genital tract. The vast majority of these neoplasms are clinically benign and easy to diagnose. In contrast, leiomyosarcomas are highly aggressive tumors that may pose considerable diagnostic problems when they display unusual (myxoid or epithelioid) morphology, ambiguous histologic features for malignancy, or an unusual anatomic distribution. Diagnostic criteria for these problematic tumors vary depending on the site and type of histologic differentiation, and are based on a combination of 3 major criteria: (1) moderate to severe cytologic atypia; (2) increased mitotic index; and (3) tumor cell necrosis. Certain benign smooth muscle proliferations may show worrisome histologic features or unusual growth patterns, causing concern for leiomyosarcoma. Furthermore, other tumors, including perivascular epithelioid tumors, may mimic leiomyosarcoma. Careful attention to the clinical and anatomic setting, cytologic and architectural features, and immunohistochemical characteristics are helpful in distinguishing these entities. This article discusses conventional smooth muscle tumors as well as unusual subtypes, with emphasis on the diagnostic criteria and problems in differential diagnosis that arise at each site within the female genital tract.

Abstract
UNLABELLED Primary pure ovarian leiomyosarcomas constitute a malignant subgroup of ovarian smooth muscle tumors which comprise only 1% of ovarian tumors. Their origin, etiology, histologic features, clinical behavior, and optimal treatment are still obscure. Malignant behavior is almost always associated with any 2 of coagulative necrosis, cellular atypia, and mitotic index greater than 10. Immunohistochemical and electron microscopic evaluations may improve diagnostic accuracy. Traditionally, International Federation of Gynecology and Obstetrics (FIGO) staging and treatment of ovarian sarcomas have been the same as for epithelial ovarian carcinomas. Although surgery was performed for all cases, the extent of surgery is debatable. Benefit and modality of adjuvant therapy is controversial. The prognosis of primary pure ovarian leiomyosarcomas is extremely poor depending on tumor stage, tumor size, grade, and mitotic index and mostly recurs in abdomen and pelvis. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to state how rare primary ovarian leiomyosarcoma (POLMS) is, explain that because of its rarity the best diagnostic and treatment modalities are not conclusive, and recall that the authors reviewed the literature to bring the readership current on POLMS.

Abstract
We studied 54 ovarian smooth muscle tumors with an emphasis on histologic criteria for malignancy. Twenty-two leiomyomas were identified, including 7 typical, 11 cellular, 2 mitotically active, 1 with bizarre nuclei, and 1 myxoid. Follow-up ranging from 12 to 240 months (mean, 77.6 months) was available for 14 patients; all were alive with no evidence of disease. Of 26 leiomyosarcomas, including 2 myxoid leiomyosarcomas, most were readily diagnosed by the presence of at least two of the following: moderate or severe cytologic atypia, mitotic rate > or =10 mitotic figures per 10 high power fields, and tumor cell necrosis. Some cytologically atypical tumors demonstrated lesser mitotic activity of 5 to 9 mitotic figures per 10 high power fields, in the absence of tumor cell necrosis. Sixty percent of these were clinically malignant, supporting a diagnosis of leiomyosarcoma in such tumors. Follow-up was available for 21 patients. Seventy-one percent developed recurrent disease at a mean of 19 months, and 62% died of their disease at a mean of 24 months. Four tumors were deemed of uncertain malignant potential, and two that were stage II both recurred in the pelvis. One case of ovarian intravenous leiomyomatosis had a benign outcome at 42 months, as did one case of ovarian leiomyoma with leiomyomatosis peritonealis disseminata at 180 months. Overall, ovarian smooth muscle tumors encompass the same varied histologic spectrum as their uterine counterparts. The main tumors in the differential diagnosis are those in the fibroma/thecoma category, spindle cell carcinomas, and metastatic gastrointestinal stromal tumors.

Abstract
Primary hepatic leiomyosarcoma is very rare and no primary myxoid leiomyosarcoma in the liver has been reported yet. Most cystic space-occupying lesions in the liver are benign in nature. But, rarely, malignancy could appear as a cystic lesion by ultrasonographic examination. A 64-year-old woman with a huge cystic mass detected by hepatic ultrasonography was diagnosed as primary hepatic myxoid leiomyosarcoma by immunohistochemical and ultrastructural studies after various image studies and fine needle aspiration biopsy of the liver mass.

Abstract
The diverse mesenchymal tumors and tumor-like lesions that occur within the female genital tract include a number of lesions that have only been recently characterized and others about which there is new information. In this group are the aggressive angiomyxoma, angiomyofibroblastoma, and cellular angiofibroma. Criteria for the distinction of these lesions are reviewed, as are the pathologic features of prognostic significance in assessing smooth muscle tumors of the vulva. The diagnostic problems that the epithelioid variant of smooth muscle tumors, both benign and malignant, may pose when they occur in various areas of the genital tract are discussed, particularly with regard to problems encountered in the ovary, a site where the diagnosis often is not considered. Recent information expanding the morphologic spectrum of fibroepithelial polyps of the genital tract is presented, and important non-neoplastic entities, including nodular fasciitis and the postoperative spindle cell nodule, are reviewed. Mesenchymal tumors of the various types seen in the soft tissues may be encountered anywhere in the female genital tract and have been the subject of particular recent interest in the ovary; issues relevant to differential diagnosis are reviewed.

Abstract
Myxoid leiomyosarcoma is an uncommon tumor which, although previously well described in the uterus, is recognized to a lesser extent at other sites. We describe 18 cases of soft tissue leiomyosarcoma in which myxoid stroma occupied >50% of the tissue examined. Patients ranged in age from 22 to 84 years old (median, 57.5 yrs) and female patients outnumbered male patients 14 to 4. Tumor locations included the limbs (6 cases), female external genitalia (4 cases), head and neck region (3 cases), chest (2 cases), nipple, paratesticular soft tissue, and perineum (one case each). The tumors had a grossly gelatinous appearance and adopted three major histologic architectures: fascicular, reticular/microcystic, and "myxofibrosarcoma-like." The tumor cells were predominantly spindled in all cases with typical features of smooth muscle differentiation; there was a mixture of spindle and epithelioid cells in one case. No cases with pure epithelioid cytology were seen. All tumors displayed immunoreactivity for smooth muscle markers (smooth muscle actin 16/17, desmin 8/18) and, in addition, four cases were positive for keratin CAM 5.2 and three for epithelial membrane antigen. The tumors had a tendency to be morphologically lower grade (9 tumors were grade I, 8 were grade II, and only 1 was grade III). Follow up was available in 13 patients with a duration of 8 months to 41 years (median, 39 mos), and revealed local recurrences (often repeated) in five cases and metastases in two cases. There were three tumor-related deaths, of which two were the result of uncontrolled local disease. The differential diagnosis of myxoid leiomyosarcoma is broad and encompasses both benign and malignant lesions. Accurate diagnosis is critical because therapies may differ widely for entities in the differential diagnosis of myxoid leiomyosarcoma.

Abstract
Myxoid lesions can be subdivided into (1) mainstream myxomas of soft tissues, (2) mainstream myxomas located outside the soft tissue, (3) inadequately substantiated myxomas, (4) myxoid soft tissue tumors or lesions not regarded as myxomas, (5) myxoid fatty conditions, (6) other soft tissue lesions and tumors that are sometimes markedly myxoid, (7) other soft tissue tumors in which myxoid foci may be seen, and (8) nonneoplastic myxoid conditions of soft tissue. More than 60 such conditions are listed and the five entities regarded as mainstream soft tissue myxomas (namely, intramuscular myxoma, juxta-articular myxoma, superficial angiomyxoma, aggressive angiomyxoma, and myxoid neurothekeoma [myxoma of nerve sheath]) are reviewed in detail. Intramuscular myxoma is exclusively intramuscular, usually affects middle-aged women, is most commonly located in the thigh, and does not recur after simple excision. Multiple intramuscular myxomas are rare and are usually associated with monostotic or polyostotic fibrous dysplasia and Albright's syndrome. Juxta-articular myxoma histologically resembles an intramuscular myxoma, but involves periarticular tendons, ligaments, joint capsules, muscles, and even the subcutis of adults. It may be associated with osteoarthritis of the adjacent joint. Some 30% recur locally. Superficial angiomyxoma also has been called cutaneous myxoma. It affects all ages, with a peak incidence in the third and fourth decades; arises in the trunk, lower limb, head, and neck regions; and usually measures less than 5 cm in diameter. Epithelial components are present in approximately 25% of tumors. Approximately one third recur locally, but there have been no metastases. Patients with multiple lesions may have the Carney complex. Aggressive angiomyxoma usually arises in the pelvic and perineal regions and affects females seven times as often as males. Tumors usually measure 10 cm or more in diameter, invade surrounding tissues, and recur in approximately 50% of cases. None have metastasized. Myxoma of nerve sheath (the myxoid variant of neurothekeoma) preferentially affects the dermis and subcutis of the cervicofacial areas and shoulders of young women. Most patients are younger than 40 years; one third of them are in the second decade of life. The majority of tumors measure between 0.5 and 1.5 cm. Only three of 102 cases compiled from the two largest published series recurred; none metastasized. The different clinicopathologic features and behavior of these five mainstream myxomas indicate that myxoma is not a single entity.

Abstract
A 34-year-old male patient with epigastralgia was found to have an esophageal submucosal tumor based on an endoscopic evaluation 6 years previously. Because an unusual appearance composed of a heterogeneous solid area and a cyst area on the endoscopic ultrasonogram and the increased size of the tumor on esophagograms over the past 3 years were suggestive of a malignant character, an operation was thus indicated. The tumor, which measured 3.5 x 2.5 x 2.0 cm in size, was enucleated using videoassisted thoracic surgery and was diagnosed to be a very rare myxoid leiomyosarcoma with a thorough pathologic examination. To our knowledge, this is only the second case of esophageal myxoid leiomyosarcoma reported in the literature. We thus consider this case, which demonstrated an unique appearance on an endoscopic ultrasonogram, to possibly be beneficial to the overall diagnostic analysis of esophageal submucosal tumors.

Abstract
Angiosarcoma most frequently occurs in the skin of the head and neck region of elderly persons, lymphedematous limbs, or in deep soft tissue but only rarely has been described to occur in the female genital tract. Four cases of angiosarcoma of the ovary are described herein. They occurred in patients 25 to 42 years old (median, 31 years). The most common clinical presentation was abdominal pain. All of the tumors were unilateral, hemorrhagic, and ranged from 3.5 cm to 14 cm (median, 13 cm). The histologic appearance of the tumors was varied, and often the vascular nature of the tumor was not apparent immediately. Some of the tumors had a fascicular growth pattern composed of spindle-shaped cells with ovoid nuclei and ample eosinophilic cytoplasm closely mimicking leiomyosarcoma. Other tumors resembled ovarian yolk sac tumor with a reticular growth pattern, whereas, in other areas, cystic structures lined by hobnailed hyperchromatic enlarged nuclei simulated clear cell carcinoma of the ovary. Despite these misleading morphologic findings, all cases were characterized, at least focally, by vasoformative channels or discrete cytoplasmic vacuoles, and all were immunoreactive for vascular markers. Two patients with spread of tumor outside of the ovary died 1 month and 2 years after initial diagnosis, respectively. Two patients with tumor confined to the ovary are alive without evidence of disease 3 and 14 months after diagnosis, respectively. The differential diagnosis of this unusual neoplasm is discussed, and the literature is reviewed.

Abstract
A case of Stage IIIC primary ovarian leiomyosarcoma in a premenopausal woman with multiple recurrences alive and well 7 years after diagnosis is presented. In addition to the typical light microscopic, immunohistochemical, and electron microscopic features of ovarian leiomyosarcoma, the tumor was progesterone receptor positive. This is 28th report of primary ovarian leiomyosarcoma and the first report of progesterone receptor in this tumor. This is the longest reported survival in a woman with this disease.
