Abstract
ABSTRACT The Epstein-Barr virus-associated smooth muscle tumor (SMT) is an uncommon neoplasm. It arises mainly in 3 immunosuppression settings: HIV-associated SMT; drug-related immunosuppression in transplant recipients; and congenital immunodeficiency disorder-associated SMT. We present 18 F-FDG PET/CT findings of an adrenal Epstein-Barr virus-associated SMT in a 65-year-old woman with a history of follicular lymphoma after chemotherapy.

Abstract
PURPOSE To evaluate the magnetic resonance imaging (MRI) features that may help distinguish leiomyosarcomas from atypical leiomyomas (those presenting hyperintensity on T2-W images equal or superior to 50% compared to the myometrium). MATERIALS AND METHODS The authors conducted a retrospective single-centre study that included a total of 57 women diagnosed with smooth muscle tumour of the uterus, who were evaluated with pelvic MRI, between January 2009 and March 2020. All cases had a histologically proven diagnosis (31 Atypical Leiomyomas-ALM; 26 Leiomyosarcomas-LMS). The MRI features evaluated in this study included: age at presentation, dimension, contours, intra-tumoral haemorrhagic areas, T2-WI heterogeneity, T2-WI dark areas, flow voids, cyst areas, necrosis, restriction on diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC) values, signal intensity and heterogeneity after contrast administration in T1-WI, presence and location of unenhanced areas. The association between the MRI characteristics and the histological subtype was evaluated using Chi-Square and ANOVA tests. RESULTS The MRI parameters that showed a statistically significance correlation with malignant histology and thus most strongly associated with LMS were found to be: irregular contours (p < 0.001), intra-tumoral haemorrhagic areas (p = 0.028), T2-WI dark areas (p = 0.016), high signal intensity after contrast administration (p = 0.005), necrosis (p = 0.001), central location for unenhanced areas (p = 0.026), and ADC value lower than 0.88 × 10-3 mm2/s (p = 0.002). CONCLUSION With our work, we demonstrate the presence of seven MRI features that are statistically significant in differentiating between LMS and ALM.

Abstract
Sonographic characterization and surveillance of paravaginal smooth muscle tumor of uncertain malignant potential. (A1) Transvaginal ultrasound with probe placed over the right vaginal wall, showing a well-defined round mass with regular contours, a mostly hypoechoic and heterogeneous echotexture, and edge shadowing, deep to the right distal third of the right vagina. (A2) Multifrequency linear probe (9-14 MHz) placed over the right labium majus revealing hyperechoic striations (arrows on A1-A2) and central flow (arrowheads on A2). (B1) Resected solid white-tan mass of bland consistency. (B2) Hematoxylin-eosin microscopy (40X) showing fusiform cells, with mild to moderate atypia. (C1) Repeat transvaginal ultrasound six-years later showing a recurrent solid oval-shaped mass with regular contour, a mostly hypoechoic heterogeneous echotexture, and an anechoic area inside the solid mass (asterisk on C2) that could represent a focus of necrosis.

Abstract
OBJECTIVE To correlate the ultrasound appearance of highly vascularized uterine myomas with their histopathological diagnosis. METHODS This was a prospective observational study of patients with a preoperative ultrasound diagnosis of a highly vascularized uterine myoma (color score of 3 or 4, according to the Morphological Uterus Sonographic Assessment (MUSA) criteria), characterized by circumferential and intralesional vascular pattern, who underwent myomectomy or hysterectomy. For each patient, ultrasound characteristics were recorded at baseline, including the number of lesions, the size, echogenicity and border regularity of the lesion, presence of cystic areas and shadowing within the myoma, and visualization of the endometrium. Ultrasound features were correlated with the definitive histological diagnosis. Ultrasound features were then compared between malignant and benign lesions. RESULTS We included 70 patients with highly vascularized uterine myomas on power/color Doppler. Their mean age was 46.5 ± 11.4 years and 13 (18.6%) were postmenopausal. At histological examination, 65 (92.9%) uterine myomas were benign lesions, comprising 32 typical leiomyomas, 29 leiomyoma variants and four adenomyomas. The remaining five (7.1%) uterine myomas were malignant masses, comprising two uterine sarcomas, one leiomyosarcoma, one neuroendocrine tumor and one uterine smooth muscle tumor of uncertain malignant potential (STUMP). The mean age of patients with a malignant lesion was significantly higher than the age of those with a benign lesion (64.8 ± 16.0 vs 42.4 ± 5.1; P < 0.001). Four out of five patients with a malignant lesion were over 45 years old. Ultrasound demonstrated cystic areas within the lesion in 10/32 (31.3%) typical leiomyomas, 16/29 (55.2%) leiomyoma variants, all four adenomyomas and in the cases of STUMP and leiomyosarcoma. Lesion borders were regular in 64/65 (98.5%) benign lesions and 2/5 (40%) malignant lesions (P < 0.05). No significant differences were observed between benign and malignant lesions with respect to echogenicity, presence of shadowing and size. The endometrium was visible in 55/65 women with benign lesions and in 2/5 with malignant lesions (P = 0.03). CONCLUSIONS Our results showed that ultrasound features of uterine myomas, such as circumferential and intralesional vascularity, cystic areas and lesion borders, are important parameters for differential diagnosis, especially when combined with the patient's age. Such features could be useful to differentiate typical myomas from benign variants and malignant lesions in a preoperative setting and to select patients that may benefit from conservative management rather than surgery. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
CASE A 34-year-old man with poorly controlled acquired immune deficiency syndrome underwent excision of a left arm mass. The histopathologic workup identified the features of an Epstein-Barr virus-associated smooth muscle tumor (EBV-SMT). The patient was readmitted 5 months later for vomiting and found to have liver metastases that were confirmed to be EBV-SMT. Six months after discharge, there was no recurrence of the arm mass or increase in the size of the liver metastases. CONCLUSION Most commonly found in immunocompromised patients, EBV-SMTs are rare tumors that can be mistaken for a leiomyosarcoma.

Abstract
RATIONALE Extrauterine leiomyomas (LMs) in women are often positive for the estrogen receptor (ER); however, almost all extrauterine leiomyosarcomas (LMSs) are negative for ER. Invasive smooth muscle neoplasms (SMNs) of the gastrointestinal tract walls are very rare and those ER statuses have not been well studied. PATIENT CONCERNS A 48-year-old woman presented to our hospital with a 10 years history of recurrent severe abdominal pain and diarrhea lasting about an hour, with frequency of about twice per year. She was clinically diagnosed with a submucosal tumor (SMT) of the transverse colon and underwent a partial transverse colectomy. DIAGNOSIS A colonoscopy revealed a 30-mm SMT in the transverse colon. A contrast abdominal computed tomography detected a 21-mm mass with significant late phase enhancement in the transverse colon and the lesion was clinically diagnosed as an SMT. Post-operative pathology confirmed a diagnosis of ER-positive locally aggressive SMN. INTERVENTIONS The patient underwent laparoscopic partial transverse colectomy. OUTCOMES The patient received no adjuvant therapy postoperatively. The patient has remained disease-free without recurrence 13 months after the surgery. LESSONS This is the first case of an ER-positive invasive SMN in the gastrointestinal tract. It highlights the difficulty in classifying some gastrointestinal SMNs as either LMs or LMSs and the importance of ER status in SMNs.

Abstract
Primary smooth muscle tumor of the pleura is exceptionally rare. The authors describe a primary smooth muscle tumor of the pleura that was discovered incidentally on chest X-ray in a 73-year-old man. Magnetic resonance imaging demonstrated a 12 x 18 x 15-cm pleura-based mass arising from the posterior mediastinum. Computerized tomography (CT) guided needle cores from the pleura showed a primary smooth muscle tumor of undetermined malignant potential. Further excision of the whole tumor showed an intimate relation to pleura, and the diagnosis of leiomyosarcoma was made. The clinical, radiological, histopathological, immunohistochemical, and ultrastuctural findings were consistent with a primary smooth muscle tumor of the pleura. This is the seventh case in the literature of a primary smooth muscle tumor of the pleura, which, to the best of the authors' knowledge, is the first such case of the pleura to be diagnosed on CT-guided needle biopsy. In conclusion, this method of investigation is recommended since it is minimally invasive but has a rewarding yield in providing the most likely diagnosis, predicting prognosis, and management planning.

Abstract
BACKGROUND Chorioangioma is the leading diagnosis for circumscribed placental lesion noted on ultrasound. Other rare intraplacental tumors may have a significant clinical impact on the mother and fetus. CASE An intraplacental, hypoechoic area consistent with chorioangioma was noted on ultrasound examination at 17 weeks' gestation. The lesion remained stable in size throughout gestation, with no evidence of fetal hydrops or polyhydramnios. At term, a live-born male infant was delivered vaginally, followed by spontaneous expulsion of the placenta. Histologic examination of the placenta revealed an intraplacental, potentially malignant smooth muscle tumor. Six weeks postpartum, total abdominal hysterectomy and pelvic node sampling were performed. No residual disease was found on the final histologic examination. CONCLUSION Although ultrasound differentiation is difficult, rare nontrophoblastic tumors should be considered in the differential diagnosis of placental masses. To our knowledge, this is the first report of such a lesion in the placenta.

Abstract
A solitary well-demarcated tumor was found in the left lung of a 53-year-old man. It was located in the posterior region of the lower lobe just adjacent to, but apart from, the pleura. It was resected by video-associated thoracic surgery. Macroscopically, the tumor was a whitish solid nodule without hemorrhage or necrosis, and it was 1.5 cm in diameter. Histologically, the tumor consisted of a proliferation of fibromuscular tissue in interlacing fascicles in which many tubular or cleft-like epithelial inclusions were involved. The epithelial inclusions showed cystic changes with goblet cell metaplasia in part, but no atypical changes. Other mesenchymal components such as cartilaginous, myxomatous or adipose tissues were not seen. The patient had no history of neoplasm, including smooth-muscle tumor. Thus, we diagnosed this tumor as a "true" fibroleiomyomatous hamartoma, as distinct from so-called fibroleiomyomatous hamartoma or benign metastasizing leiomyoma, which are usually found in the lungs of women who have had hysterectomies, as multiple fibromuscular nodules. We report here this rare case and we review and discuss published reports of fibromuscular tumors of the lung.

Abstract
Smooth-muscle tumor of the rectum is rare, and the therapeutic strategy is still controversial. Endorectal ultrasound was used to evaluate three patients with smooth-muscle tumor of the rectum. Endorectal ultrasound demonstrated a homogenous hypoechoic tumor without invasion to the perirectal tissue in two patients. The tumor was 5 cm in diameter in one patient and 4 cm in diameter in the other patient, and they were excised locally. Their histologic types were leiomyoma and leiomyosarcoma. The third patient had a recurrent leiomyosarcoma. Proctosigmoidoscopy found a linear lesion with ulcerated mucosa on the rectal wall. Endorectal ultrasound observed a hypoechoic solid tumor of 3.5 cm x 1 cm, which involved the mucosal, submucosal, and muscle layers of the rectal wall. Disruption of the first hypoechoic layer was identified. Abdominoperineal resection was performed. Endorectal ultrasound follow-up revealed no evidence of recurrence in any of these patients. Endorectal ultrasound can help to define the extent of disease and may be a useful adjunct in deciding about the appropriate surgical procedure in these diseases.

Abstract
In order to elucidate the efficacy in gastric surgery, we evaluated seven resected cases of a submucosal gastric tumor in which laparoscopic techniques were used. The patients consisted of 1 man and 6 women. The tumors were located in the upper, middle, and lower third of the stomach in 4, 1, and 2 cases, respectively. Three tumors were located mainly on the anterior gastric wall, 2 were on the posterior wall, and 2 were on the lesser curvature. The resected tumor size averaged 3.2 x 2.6 cm. The tumors were classified as intraluminal type (4 cases) and the extraluminal type (3 cases) according to the classification of growth type. A histopathological examination identified 4 leiomyomas, 1 leiomyosarcoma, and 4 smooth muscle tumors of indeterminate malignant potential. After a tumor resection, no recurrence of the lesions occurred during the postoperative follow-up. An extraluminal growing tumor was easily resected by the laparoscopic method without any additional procedures, and this therefore seemed to be a good indication for the laparoscopic method. In contrast, an intraluminal tumor was found to be more difficult to resect using the laparoscopic method without a companion method, e.g., intraoperative endoscopy, because of the difficulties in the detection and resection of the tumor from the serosal side. A more efficient technique must therefore be developed for this type of tumor.
