ABSTRACT
Diffuse oesophageal leiomyomatosis is a rare benign disease in the paediatric population. This report highlights a recent clinical case, together with a narrative review of current world literature.An early middle childhood girl with recurrent lower respiratory tract infections for 2 years was noted to have a retrocardiac lesion on chest X-ray, later confirmed to be an oesophageal mass on CT imaging. She underwent an Ivor-Lewis oesophagogastrectomy and a Heineke-Mikulicz pyloroplasty. Pathology examination revealed type I diffuse oesophageal leiomyomatosis. Alport syndrome was later confirmed following an episode of postoperative haematuria, which was corroborated by electron microscopy examination following renal biopsy.With an oesophageal mass lesion and Alport syndrome, oesophageal leiomyomatosis should be suspected in any patient with a clinical history of dysphagia and/or respiratory symptoms. Endoscopic ultrasound-guided tissue biopsy is valuable for diagnosis of all suspected lesions. Surgical resection is mandatory to effect cure.

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome is an autosomal-dominant disorder that results from a germline pathogenic variant in the fumarate hydratase (FH) gene on chromosome 1, characterised by renal cell carcinoma (RCC), cutaneous leiomyoma and uterine leiomyoma. Leiomyosarcomas are reported in less than 1% of those with HLRCC. We report a case of a man in his 30s who had a long-standing plaque excised from the left upper arm after undergoing a radical nephrectomy for a fumarate-deficient RCC, with histological exam revealing a grade 1 leiomyosarcoma. Genetic testing confirmed a heterozygous pathogenic variant in the FH gene. This is a rare case of leiomyosarcoma associated with HLRCC, and our patient remains under surveillance with interval abdominal imaging and skin examination. Leiomyosarcomas are difficult to distinguish clinically from their benign counterpart; therefore, histopathological examination is paramount with a low threshold for excision.

Reed Syndrome, or hereditary leiomyomatosis and renal cell carcinoma syndrome, is a rare, autosomal dominant genetic condition that predisposes individuals to a triad of cutaneous leiomyomas, uterine leiomyomas and renal cell carcinoma. Cutaneous leiomyomas are often the first manifestation of the syndrome, occurring in 76% of patients and average 26 in number. We present a case of a 47 year old female with Reed Syndrome with an unusually extensive cutaneous burden, with a total of 361 cutaneous lesions, far above the average reported number of 26. Due to the extent of her cutaneous burden, painful nature of the lesions and failure to respond to standard therapies, she was referred for fully ablative Erbium:Yag laser resurfacing therapy. The use of fully ablative Erbium:YAG laser resurfacing therapy for treatment of cutaneous leiomyomas has not been reported in the literature to date. One year following laser therapy, the treatment area not only began to repigment, but there was also no evidence of cutaneous leiomyomas recurrence or associated pain. Given the effectiveness of this unique therapy, fully ablative Erbium:YAG laser resurfacing should be kept in mind as a treatment option for both cosmetic and symptomatic cutaneous leiomyomas.

Disseminated peritoneal leiomyomatosis (DPL) is a rare and benign clinical entity. It is also known as leiomyomatosis peritonealis disseminata (LPD). Here, we report and discuss a case of a primiparous woman in her early 40s who presented with heavy, prolonged, painful menses and heaviness in her lower abdomen. She underwent a laparoscopic myomectomy for a fibroid uterus, 12 months ago for similar complaints. On workup, she was diagnosed with DPL. We performed a total abdominal hysterectomy with bilateral salpingectomy, low anterior resection with stapled colorectal anastomosis and excision of peritoneal tumour deposits in consortium with the gastrosurgery team. Her postoperative period was uneventful, and the patient was discharged on postop day 6. Her histopathology report was consistent with leiomyoma; the follow-up period was uneventful.

Uterine leiomyoma invading internal iliac vein and consequently disseminating into the right atrium is an extremely rare condition, and surgical strategy is controversial. Here, we reported a specific case with successful surgical resection through one-stage total hysterectomy, bilateral oophorectomy, and the intracardiovascular lesion. This procedure would be an optimal choice for uterine leiomyoma invading inferior vena cava and spreading to right atrium.

RATIONALE: Cellular uterine leiomyomas (CL) represent the prevailing subtype among uterine leiomyomas. In this study, we report a case of recurrent peritoneal disseminated uterine fibroids 2 years after single-port laparoscopic gasless myomectomy. This article endeavors to examine the potential limitations of the aforementioned surgical procedure and outline the distinguishing features of recurrent cases with primary postoperative pathology as CL. Additionally, it aims to provide a summary of previous retrospective studies on CL and propose the existence of immunohistochemical molecules that may serve as predictors for the postoperative recurrence of cellular uterine fibroids. The ultimate objective is to enhance clinicians' comprehension of the disease. PATIENT CONCERNS: Two years ago, the patient underwent a single-port gasless laparoscopic myomectomy for uterine fibroids. Gynecological color Doppler ultrasound conducted 3 months ago revealed recurrence of uterine fibroids, and the patient experienced abdominal distension, mild urinary frequency, and constipation for the past month. DIAGNOSES: After the second surgical procedure, a comprehensive pathological examination and immunohistochemical analysis of both the uterine mass and metastatic lesions revealed that the definitive diagnosis was CLs. INTERVENTIONS: The patient underwent the total hysterectomy, bilateral salpingectomy, pelvic adhesiolysis, omental mass resection, mesenteric mass resection, and pelvic peritoneal mass resection. All specimens were sent for rapid frozen examination and showed to be leiomyomas. OUTCOMES: The patient was discharged from the hospital on the 10th day after the operation. At the date of writing the article, the patient had no recurrence for 1 year and 5 months. LESSONS: The single-port gasless approach did not achieve the desired reduction in fibroid recurrence, as anticipated by the surgeon. The act of pulling the tumor towards the abdominal incision for resection, on the contrary, may serve as an iatrogenic factor contributing to postoperative recurrence of CL into peritoneal dissemination leiomyomatosis. The single-port gasless assisted bag may be a more suitable option for myomectomy. The utmost effort should be made to prevent the potential recurrence of myoma caused by iatrogenic factors.

OBJECTIVE: To analyse the risk factors for post-operative recurrence or progression of intravenous leiomyomatosis and explore the impact of different treatment strategies on patient prognosis. METHODS: Patients with intravenous leiomyomatosis who underwent surgery from January 2011 to December 2020 and who were followed for ≥3 months were included. The primary endpoint was recurrence (for patients with complete resection) or progression (for patients with incomplete resection). Kaplan-Meier survival analysis was used to analyse the factors affecting recurrence. RESULTS: A total of 114 patients were included. The median age was 45 years old (range 24-58). The tumors were confined to the uterus and para-uterine vessels in 48 cases (42.1%), while in 66 cases (57.9%) it involved large vessels (iliac vein or genital vein and/or proximal large veins). The median follow-up time was 24 months (range 3-132). Twenty-nine patients (25.4%) had recurrence or progression. The median recurrence or progression time was 16 months (range 3-60). Incomplete tumor resection (p=0.019), involvement of the iliac vein or genital vein (p=0.042), involvement of the inferior vena cava (p=0.025), and size of the pelvic tumor ≥15 cm (p=0.034) were risk factors for recurrence and progression. For intravenous leiomyomatosis confined to the uterus or para-uterine vessels, no post-operative recurrence after hysterectomy and bilateral oophorectomy occurred in this cohort. Compared with hysterectomy and bilateral oophorectomy, the risk of recurrence after tumorectomy (with the uterus and ovaries retained) was significantly greater (p=0.009), while the risk of recurrence after hysterectomy was not significantly increased (p=0.058). For intravenous leiomyomatosis involving the iliac vein/genital vein and the proximal veins, post-operative aromatase inhibitor treatment (p=0.89) and two-stage surgery (p=0.86) were not related to recurrence in patients with complete tumor resection. CONCLUSION: Incomplete tumor resection, extent of tumor lesions and size of the pelvic tumor were risk factors for post-operative recurrence and progression of intravenous leiomyomatosis.

Reed's syndrome (RS) is a rare autosomal-dominant disorder characterised by multiple cutaneous and uterine leiomyomas, with a strong tendency for renal cell carcinoma (RCC) development. A woman in her 50s, who had previously undergone total abdominal hysterectomy due to multiple uterine leiomyomas, presented with painful nodules on her trunk and right arm for the past 6 years. These nodules were confirmed as leiomyomas through histopathology. Diagnosis of RS was established through clinicopathological correlation and positive family history, particularly her mother's. Early-onset uterine leiomyomas in patients with a similar family history should raise suspicion for RS, necessitating vigilant long-term follow-up. RCC detection requires mandatory renal imaging. Screening family members and providing genetic counselling are crucial.

RATIONALE: Intravascular/intravenous leiomyomatosis (IVL) is a peculiar variant of uterine leiomyoma that is classified as a histologically benign smooth muscle tumor with a biological behavior similar to that of a malignant tumor. It is characterized by the proliferation of leiomyomas spreading along the uterine and extrauterine venous circulation. PATIENT CONCERNS: Herein, we present 2 cases of IVL who had completely different clinical manifestations to stress the need for constant vigilance of IVL diagnosis and the understanding of uterine leiomyoma heterogenicity. Case 1 was registered for fever without specific triggering factors, irregular menstruation and clinically diagnosed uterine diverticula, while no information about fibroids was mentioned. Case 2 was characterized by an aggressively growing abdominal mass. With a large space-occupying lesion in the right abdominopelvic cavity and no imaging evidence of involvement of the iliac vein or above vein, the patient was initially diagnosed with multiple myomata. DIAGNOSES: Both patients' diagnoses were confirmed as IVL by histopathology. To our knowledge, the mass of case 1 is the minimum IVL in the English literature. INTERVENTIONS: Subtotal hysterectomy with bilateral salpingectomy was performed on the former, while total hysterectomy with bilateral salpingectomy was performed on the latter. OUTCOMES: Both patients were comfortable, and no relapse occurred. LESSONS: Two cases in the study showed 2 different proceeding stages of the same disease and corroborated multiple pathogeneses, which have been mentioned in the available literature on IVL. Our work provides both supplement for clinical data to facilitate further research and better understanding of special types of fibroids to clinicians.

OBJECTIVES: The aim was to explore the magnetic resonance imaging (MRI) features of stage-I intravenous leiomyomatosis (IVL). MATERIALS AND METHODS: From January 2019 to January 2023, clinical, pathological, and MRI data were collected from 19 cases confirmed by surgical pathology. Two radiologists retrospectively measured the tumor sizes, T1WIs, T2WIs, and ADC values and evaluated contrast-enhanced T1WIs, DWIs, complications and parauterine infiltrations. The number of tumor cells and the total nuclear area were measured. The percentage of tumor cell area out of the total area was used as the tumor cell density. RESULTS: Nineteen patients with stage-I IVL aged 33 to 66 years (mean age: 46 ± 7.6 years) were included in this study. All 19 cases were located in the myometrium or parametrium, with a mean diameter of 11.2 ± 4.8 cm. Among these cases, 14 (73.6%) were associated with leiomyoma, and six (31.6%) involved the broad ligament. Isointensity was observed in the T1WIs of 12 cases (63.2%), while slight hypointensity was seen in five patients (26.3%). Isointensity was observed in the on T2WIs of four cases (21.1%), and iso- or slight hyperintensity was observed in 15 cases (78.9%). A significant difference was detected between the normalized T2WIs of IVL and myometrium (p < 0.001). A Pearson correlation test showed demonstrated a negative correlation between the ADC and tumor cell density values (r = - 0.946, p < 0.001). Tortuous vessels were present in 17 cases (89.5%) within or next to the lesions, and multiple winding cord-like filling defects were seen in 11 cases (57.9%) within the tortuous vessels on the T2WIs. CONCLUSION: Identifying the characteristic MRI features of stage-I IVL helped improve the diagnostic accuracy achieves for this rare tumor. Stage-I IVL often presents as a large mass accompanied by leiomyoma, and it easily invades the broad ligament. TIWI signals exhibited isointensity, and T2WI signals contained iso- or slight hyperintensity. Tortuous vessels were present within or next to the lesions, and multiple winding cord-like filling defects were observed within the tortuous vessels on the T2WIs.

OBJECTIVE: This study provides a concise overview of diagnostic and treatment strategies for intravenous leiomyomatosis (IVL), a rare disease with nonspecific clinical manifestations, based on cases from a tertiary referral hospital in China. METHODS: We retrospectively analyzed 11 premenopausal patients with confirmed IVL between 2018 and 2022. Clinical data from Ultrasound, Enhanced CT, and MRI were studied, along with surgical details, postoperative pathology, and follow-up information. RESULTS: Premenopausal patients showed no disease-specific symptoms, with 90.9% having a history of gynecological or obstetric surgery, and 72.7% having prior uterine fibroids. Cardiac involvement was evident in two cases, with echocardiography detecting abnormal floating masses from the inferior vena cava. Pelvic ultrasound indicated leiomyoma in 90.9% of cases, with ≥ 50 mm size. Surgery was the primary treatment, and lesions above the internal iliac vein resulted in significantly higher intraoperative blood loss (median 1300 ml vs. 50 ml, p = 0.005) and longer hospital stays (median 10 days vs. 4 days, p = 0.026). Three patients with lesions above the inferior vena cava required combined surgery with cardiac specialists. Recurrence occurred in 2 out of 11 patients with incomplete lesion resection. CONCLUSIONS: IVL mainly affects premenopausal women with uterine masses, primarily in the pelvic cavity (Stage I). Pelvic ultrasound aids early screening, while Enhanced CT or MR assists in diagnosing and assessing venous lesions. Complete resection is crucial to prevent recurrence. Lesions invading the internal iliac vein and above pose higher risks during surgery. A multidisciplinary team approach is essential for patients with lesions above the inferior vena cava, with simultaneous surgery as a potential treatment option.

PURPOSE: This case report aims to present a rare and challenging clinical scenario involving diffuse uterine leiomyomatosis (DUL), an infrequently encountered benign uterine pathology. The primary objective is to describe this unique case's clinical presentation, diagnostic challenges, and subsequent management. METHODS: A detailed analysis of the patient's medical history, diagnostic evaluations, and treatment approach was conducted. A relevant literature review on DUL was also performed. This case report includes high-resolution images and figures, showcasing MRI scans, surgical procedures, and histopathology slides related to the case. RESULTS: The case report outlines the clinical journey of a patient with DUL, an exceptionally rare uterine condition characterized by the uncontrolled proliferation of smooth muscle cells forming nodules and fascicles. This case illustrates the diagnostic complexities associated with DUL, as it mimics other uterine pathologies such as leiomyomas or adenomyosis. The patient's clinical presentation included abnormal uterine bleeding, heavy menstrual bleeding, fertility issues, and dysmenorrhea, leading to initial misdiagnoses. Surgical intervention eventually addressed the condition with corresponding images illustrating the procedures. CONCLUSION: This case report highlights DUL's rarity and diagnostic challenges. Clinicians must be vigilant when encountering similar clinical presentations, ensuring a comprehensive diagnostic workup to differentiate DUL from other uterine pathologies. Enhanced awareness among healthcare providers and further research into DUL's pathophysiology is essential for accurate diagnosis and timely management. The presented case underscores the need for tailored approaches to managing DUL and expanding the knowledge base surrounding this puzzling uterine disorder.

A síndrome de Reed ocorre em mulheres com múltiplos leiomiomas cutâneos e leiomiomatose uterina. Relatam-se três casos de pacientes do sexo feminino, acompanhadas em hospital universitário, com pápulas e nódulos eritêmato-acas- tanhados dolorosos em membros superiores e tórax, agravados por frio, pressão e estresse, e associados a miomatose uterina. Foram realizados diversos tratamentos prévios, sem sucesso, tais como: aplicação de corticoterapia e toxina botulínica intralesional, bloqueadores de canais de cálcio, neuromoduladores e analgésicos orais. Foi, então, realizado tratamento cirúrgico, com melhora dos sintomas. O co- nhecimento e o esclarecimento dessa síndrome é fundamental para estabelecer a relação com miomatose uterina e câncer de células renais, para que, então, a partir da lesão de pele, se faça o rastreio das demais neoplasias, diagnóstico precoce e a educação em saúde.
Reed syndrome occurs in women with multiple cutaneous leiomyomas and uterine leiomyomatosis. We report the case of three female patients followed at a university hospital with painful erythematous-brown papules and nodules on the upper limbs and chest, aggravated by cold, pressure, stress, and associated with uterine myoma- tosis. Several previous unsuccessful treatments were performed, such as the applica- tion of corticotherapy and intralesional botulinum toxin, calcium channel blockers, neuromodulators, and analgesics. Surgical treatment was performed with the im- provement of symptoms. Knowledge and clarification of this syndrome are essential to establish a relationship between uterine myomatosis and renal cell neoplasm, so that, after the skin lesion, screening for other neoplasms, early diagnosis, and health education can be carried out.

Intravenous leiomyomatosis is a rare type of tumor that is histologically benign but biologically invasive. It originates from the smooth muscle of the uterine or the uterine vein. It can grow through the uterus and extend into the pelvic cavity, or grow along the veins without invading the wall of the venous vessel itself. The tumors are estrogen-dependent and can metastasize through the bloodstream. Thus, in addition to continuous growth, some tumors exhibit isolated growths in the venous system and heart chambers or show disseminated growth in the lungs, although distant metastasis to other regions usually do not occur. Currently, there is limited research on this disease, the majority of which are case reports, surgical experience summaries, and differentiation from ordinary gynecological myomas in terms of pathogenesis and radiological diagnostic experience. There are two main theories on the origin of the disease: uterine smooth muscle and smooth muscle of the uterine veins. Some studies have verified the role of estrogen, progesterone receptor-related pathways, and angiogenesis in the development of the disease. The clinical symptoms of this disease are varied, depending on the affected area. In the early stages, when the tumor only affects the pelvic cavity, patients show mild symptoms resulting from pelvic organ compression. When it progresses to the inferior vena cava and heart, patients show more complex symptoms resulting from venous return obstruction, cardiac obstruction, and hemodynamics appearing. Different institutions have proposed different disease staging and classification strategies for different clinical purposes. Some are based on the affected area of the lesion; others are based on the size of the tumor. Although surgery remains the main treatment for this disease, the specific surgical approach, adjuvant drug therapy, and prognosis still need further exploration.

BACKGROUND: Intravenous leiomyomatosis (IVL) is a rare and specific type of smooth muscle tumor that is histologically benign but has a malignant biological behavior. It is commonly associated with a history of uterine leiomyomas. CASE PRESENTATION: A 36-year-old woman, G1P1, presented to the hospital with left lower abdominal pain for 2 months and she has accepted hysteroscopic myomectomy about 1 year ago. Ultrasound venography, echocardiography and computed tomography venography (CTV) of inferior vena cava were performed, which revealed IVL located in left intramural myometrium walls growing along the left ovarian vein reaching the level of the lumbar 5-sacral 1 disc. Laparoscopic bilateral salpingo-oophorectomy and hysterectomyis were scheduled. The IVL in the left ovarian vein and parauterine venous plexus were detected and excised completely during surgery. IVL was diagnosed by postoperative pathology and immunohistochemistry. The patient recovered well after surgery. No surgical-related or anesthesia-related complications occurred.The 3-month follow-up CTV of inferior vena cava and echocardiography examination revealed normal. CONCLUSIONS: The cause of IVL is unknown, this observation demonstrates that hysteroscopic myomectomy might lead to the occurrence of IVL.
