Leiomyosarcoma of urinary bladder (LMS-UB) is a highly malignant mesenchymal tumor, accounting for less than 0.5% of all bladder malignancies, with a predominant clinical presentation of hematuria. Here we report a case of low-grade LMS-UB. A 44-year-old male patient was admitted to the hospital with urodynia for 2 weeks. The patient's pelvis CT showed a mass on the right part of the bladder. For this reason, he was initially diagnosed with bladder cancer. We performed a robot-assisted laparoscopic enucleation of the bladder tumor and low-grade LMS-UB was diagnosed with the histopathological examination. He underwent 5 cycles of adjuvant chemotherapy after surgery. At 19months postoperative follow-up, the patient had no symptoms, recurrence, or distant metastasis. There is no report on the treatment of LMS-UB with minimally invasive enucleation worldwide. This case provides a new comprehensive treatment method of enucleation combined with adjuvant chemotherapy for early low-grade LMS-UB to reduce complications and improve patients' quality of life after surgery.

Primary ovarian leiomyosarcoma is a very rare tumor which is most commonly seen in postmenopausal women. Primary ovarian leiomyosarcoma has a very poor prognosis, with less than 20% of patients being alive at 5 years. The case is a 51‑year‑old female who presented with a lower abdominal mass secondary to an ovarian new growth. An exploratory laparotomy, peritoneal fluid cytology, unilateral salpingo‑oophorectomy with malignant frozen section of affected ovary, which revealed malignant tumor, proceeded with surgical staging total abdominal hysterectomy contralateral salpingo‑oophorectomy, then proceeded to complete surgical staging with infracolic omentectomy, Jackson‑Pratt drain insertion was performed. Microscopic and immunohistochemical findings established the diagnosis of primary ovarian leiomyosarcoma. Surgery is the cornerstone of treatment, while the role of chemotherapy and radiotherapy is still not clear because substantial data are lacking. The prognosis of primary pure ovarian leiomyosarcomas is extremely poor and there is no established treatment modality for this rare type of tumor.

Duodenal leiomyosarcoma is a rare condition with a poor prognosis. Early diagnosis of duodenal leiomyosarcoma is challenging because it presents with nonspecific symptoms and endoscopic biopsies usually do not enable a definitive diagnosis. Duodenal leiomyosarcomas are diagnosed on the basis of the histopathological identification of a mesenchymal lesion composed of malignant tumor cells that on immunohistochemical examination is positive for smooth muscle actin and desmin. We report the case of a 38-year-old man who presented with gastrointestinal bleeding and obstruction who was diagnosed with duodenal leiomyosarcoma after surgical resection.

This is a case report of simultaneous primary leiomyosarcomas in the spine and liver. A 64-year-old woman presented to the Seoul Paik Hospital with epigastric discomfort and constipation that she had experienced for two months. A physical examination revealed severe tenderness around the thoraco-lumbar junction. Esophagogastroduodenoscopy showed an ulceroinfiltrative lesion on the gastric angle. An abdominopelvic CT scan revealed two low attenuated lesions in the S4 and S8 regions of the liver, as well as a soft tissue mass at the T10 vertebra. Percutaneous ultrasonography-guided needle biopsy of the hepatic nodules revealed a leiomyosarcoma. The tumor at the T10 vertebra was removed to avoid spinal cord compression. The histology of this tumor was compatible with that of leiomyosarcoma. The potential primary sites for leiomyosarcoma, including the lung, thyroid, breast, kidney, genitourinary organs, and gastrointestinal tract, were subsequently investigated. No detectable abnormal findings that would suggest the origin of the tumor were found. Synchronous primary leiomyosarcomas in the spine and liver are quite rare and have a poor prognosis.

Leiomyosarcoma is a rare and aggressive soft tissue sarcoma originating in smooth muscle cells. There are two forms of primary superficial leiomyosarcomas depending on the origin and prognosis, one derived from the dermis and the other from the subcutaneous tissue of the skin. Middle-aged to elderly men are particularly affected by this type of cancer. Leiomyosarcomas of the head and neck are quite rare, accounting for approximately 3%~10% of all cases. We report herein a case of subcutaneous leiomyosarcoma of the scalp in a 47-year-old female patient.

Leiomyosarcoma of the bladder is a very rare tumor and it has been reported in less than 200 cases in the literature which represent 0.1% of all nonurothelial bladder tumors. We experienced a case of sarcoma of bladder that protruding into the urinary bladder in 51-year-old woman. She underwent mass excision with enucleation for the bladder function preservation. Pathologically, the mass consisted of high grade leiomyosarcoma. In immunohistochemical study, tumor showed positive reactions for smooth muscle actin and desmin. After mass excision, follow-up radiation treatment is ongoing. Herein, we present the case of a high-grade leiomyosarcoma with literature review.

For the modern practice of cancer surgery, the concept of oncovascular surgery (OVS), defined as cancer resection with concurrent ligation or reconstruction of a major vascular structure, can be very important. OVS for advanced cancers requires specialized procedures performed by a specialized multidisciplinary team. Roles of oncovascular surgeons are summarized as: a primary surgeon in vessel-origin tumors, a rescue surgeon treating complications during cancer surgery, and a consultant surgeon as a multidisciplinary team for cancer surgery. Vascular surgeons must show leadership in cancer surgery in cases of complex advanced diseases, such as angiosarcoma, leiomyosarcoma, intravenous leiomyomatosis, retroperitoneal soft tissue sarcoma, iatrogenic injury of the major vessels during cancer surgery, pancreatic cancer with vascular invasion, extremity soft tissue sarcoma, melanoma and others.

In this study, we summarize the clinical role of magnetic resonance imaging (MRI) in the diagnosis of patients with malignant uterine neoplasms, including leiomyosarcoma, endometrial stromal sarcoma, adenosarcoma, uterine carcinosarcoma, and endometrial cancer, with emphasis on the challenges and disadvantages. MRI plays an essential role in patients with uterine malignancy, for the purpose of tumor detection, primary staging, and treatment planning. MRI has advanced in scope beyond the visualization of the many aspects of anatomical structures, including diffusion-weighted imaging, dynamic contrast enhancement-MRI, and magnetic resonance spectroscopy. Emerging technologies coupled with the use of artificial intelligence in MRI are expected to lead to progressive improvement in case management of malignant uterine neoplasms.
