RESUMO
BACKGROUND: Ovarian hemangioma is an extremely rare tumor with atypical clinical manifestations, often discovered incidentally during autopsy or surgery. Approximately 60 cases have been reported in the past, but no more than 10 cases have been investigated by MRI and ultrasound (US). CASE PRESENTATION: ln this paper, we reported a 51-year-old female patient with Ovarian Hemangioma who had no symptoms of abdominal pain, abnormal vaginal bleeding or discharge, or any other discomfort. Laboratory tests revealed an elevated serum carbohydrate antigen (CA125) of 48.99U/ml (reference range: 0-35U/ml). Multiparametric 3.0T magnetic resonance imaging (MRI) showed a cystic solid mass with a clear boundary and regular shape in the left ovarian area and minimal ascites in the abdominal cavity. The histological examination of the mass confirmed an ovarian hemangioma. CONCLUSION: The MRI findings of ovarian hemangiomas are highly similar to those observed in hepatic hemangiomas, emphasizing the distinctive radiological characteristics specific to this condition in the ovary. This paper presents an overview of the typical MRI findings associated with ovarian hemangioma, which holds great importance for accurate diagnosis and effective treatment.

Diagnosing liver lesions is crucial for treatment choices and patient outcomes. This study develops an automatic diagnosis system for liver lesions using multiphase enhanced computed tomography (CT). A total of 4039 patients from six data centers are enrolled to develop Liver Lesion Network (LiLNet). LiLNet identifies focal liver lesions, including hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC), metastatic tumors (MET), focal nodular hyperplasia (FNH), hemangioma (HEM), and cysts (CYST). Validated in four external centers and clinically verified in two hospitals, LiLNet achieves an accuracy (ACC) of 94.7% and an area under the curve (AUC) of 97.2% for benign and malignant tumors. For HCC, ICC, and MET, the ACC is 88.7% with an AUC of 95.6%. For FNH, HEM, and CYST, the ACC is 88.6% with an AUC of 95.9%. LiLNet can aid in clinical diagnosis, especially in regions with a shortage of radiologists.

Hemangiomas of the nasal cavity are extremely rare in the practice of an otorhinolaryngologist and can be presented in various histopathological variants. Scientific data on hemangiomas of the sinonasal region are analyzed and systematized. The article describes the principles of diagnosis and choice of the method of surgical treatment of hemangiomas. An analysis of the literature data shows that with hemangiomas of the nasal cavity, a comprehensive examination of the patient is required, including collection of complaints and anamnesis, endoscopy of the nasal cavity and computed tomography of the paranasal sinuses, and with significant hemangiomas spreading to neighboring anatomical areas, magnetic resonance imaging with intravenous contrast.

BACKGROUND: Adrenal hemangiomas are extremely rare benign tumors that often need to be distinguished from malignancies. Adrenal tumors >4 cm in size are treated surgically because the possibility of malignancy cannot be ruled out. Traditionally, open surgery has been the mainstay of treatment; however, in recent years, robot-assisted surgery has been increasingly used for tumors of larger size and suspected malignancy. Here, we report a case of robot-assisted adrenalectomy for an 11 cm adrenal hemangioma. CASE REPORT: A 62-year-old male with lateral abdominal pain was referred to our hospital for further examination and treatment. His medical history was significant for hypertension, diabetes, and dyslipidemia. Computed tomography revealed an 11 cm left adrenal tumor, and all endocrinological screening tests were negative. Because the possibility of malignancy could not be ruled out, a robot-assisted adrenalectomy was performed. The operation time was 129 min, and the estimated blood loss was 7 ml. Pathological findings revealed an adrenal hemangioma. The postoperative course was uneventful, and patient's condition subsequently improved postoperatively. CONCLUSION: Robot-assisted adrenalectomy was performed for a giant adrenal hemangioma without any complications. Robotic surgery is useful for resecting adrenal hemangiomas even exceeding 11 cm in diameter.

OBJECTIVE: To explore the genetic basis and pathogenesis for a child with type I Hereditary hemorrhagic telangiectasia (HHTâ ) and Splenic sinus shore cell hemangioma (LCA). METHODS: A child with HHT complicated with LCA diagnosed at the First Affiliated Hospital of Dali University in April 2022 was selected as the study subject. Clinical data of the child and her relatives were collected, and pathogenic variants were screened by whole exome sequencing. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The patient, a 16-year-old female, had recurrent epitaxis since childhood, which sometimes necessitated hemostasis treatment. She also had splenectomy due to splenic rupture and was diagnosed with LCA. Her father and grandmother also had a history of recurrent epitaxis. Her father had deceased due to cerebral vascular rupture. The child was found to harbor a c.360+1G>A variant in the ENG gene. The same variant was not found in her asymptomatic mother and brother. CONCLUSION: The c.360+1G>A variant of the ENG gene probably underlay the pathogenesis in this child.

RATIONALE: Multilocular cystic hemangioma is a rare benign tumor classified as an atypical hemangioma. Currently, there are limited imaging reports available, and the imaging characteristics can be challenging to distinguish from other malignant multilocular cystic liver diseases such as cystadenocarcinoma, necessitating confirmation through pathological diagnosis. Here, we discuss the imaging features of 3 cases of multilocular cystic hemangiomas. PATIENT CONCERNS AND DIAGNOSES: Case 1 was a 24-year-old young female, and Case 2 involved a 60-year-old elderly male. Both patients were asymptomatic and physical examination revealed hepatic space-occupying lesions. Imaging findings revealed multilocular cystic lesions in the left liver with septa, calcification, a high diffusion-weighted magnetic resonance imaging (DWI) signal at the edge of the lesion, and progressive enhancement of the cyst wall and septa. Case 3 involved a 50-year-old male patient with epigastric distending pain for 1 month and sudden severe abdominal pain for 14 hours. Imaging results revealed a multilocular cystic lesion in the left liver with septa and tumor bleeding, a high DWI signal, and an enhanced cyst wall and septa. The pathological diagnosis confirmed a hepatic hemangioma. INTERVENTIONS: All 3 patients underwent liver tumor resection. OUTCOMES: All 3 patients recovered successfully without any intraoperative or postoperative complications during the follow-up periods of 5 years, 6 months, and 5 months. There were no signs of recurrence. LESSONS: Liver imaging revealed multilocular cystic lesions with features, such as compartmentalization, calcification, or bleeding. Multilocular cystic hemangiomas should be considered in imaging diagnosis. Enhancing our understanding of multilocular cystic hemangiomas can aid in improving the differential diagnosis of other malignant multilocular cystic liver diseases, ultimately reducing unnecessary liver resection.

INTRODUCTION: Placental chorioangioma is a benign placenta tumour. Majority of cases, the placental chorioangioma are small and no maternal and fetal complications. We highlight a case diagnosed with large placental chorioangioma with an intrapartum event associated with significant maternal and perinatal morbidity. METHOD: A 38-year-old woman, Gravida 3 Para 1, with one previous miscarriage, presented with preterm labour at 33 weeks gestation. Antenatally, she was referred to a feto-maternal specialist for finding a placental tumour size 12 × 10 cm. Features are consistent with placental chorioangioma with polyhydramnios. The anomaly scan was normal. Antenatal fetal surveillance with Doppler studies were normal. RESULTS: During this admission, corticosteroid was given together with a tocolytic agent and opioid analgesia. Unfortunately, the labour progressed, and the patient felt reduced in fetal movement. The cardiotograph showed suspicious tracing. We proceed with emergency caesarean delivery. The placenta was sent for histopathology assessment which confirmed a large placental chorioangioma. The baby was born with Apgar's score of 9 at 1 min, pH of 7.28 and lactate of 7.28 with anaemia and thrombocytopenia. The uterus developed intermittent uterine atony, and the uterotonic agent was given. She recovered well post-delivery. The baby was admitted to the neonatal intensive care unit (NICU) and received a blood product transfusion and discharged from NICU on day 15 of life. DISCUSSION: Large placental chorioangioma is associated with polyhydramnios, preterm labour, postpartum haemorrhage, fetal anaemia, fetal distress, fetal hydrops and possible perinatal death. Multidisciplinary team involvement with feto-maternal specialists, anaesthetic and neonatologists would improve the outcome of both mother and fetus.

The two most prevalent childhood vascular abnormalities are infantile hemangioma (IH) and port-wine stain (PWS). They become apparent shortly after birth but have distinct pathophysiology and clinical manifestations. The goal of this study was to determine if mother's history of angioma or PWS is associated with these vascular abnormalities. We evaluated an UK anonymized electronic medical records database with medical records that were linked between children and their mothers. Cox proportional hazards models were used to evaluate the association between maternal factors and the time of onset of either IH or PWS in children. Between 2004 and 2021, 639,085 children were linked to their mom's medical data with a total of 4,270,773 person-years of follow up. Children born to mothers with an angioma as compared to a mother without an angioma were more than 60% more likely to have an IH (HR: 1.64 [1.07, 2.52]). Children born to mothers with a PWS as compared to children born to mothers without a PWS were nearly 20 times more likely to have a PWS (18.95 [4.71,76.26]). Mothers with angiomas were not more likely to have children with PWS and mothers with PWS were not more likely to have children with IH. The effect estimates were minimally changed after adjustment. We demonstrated that children born to mothers with angiomas or PWS were at increased risk of IH or PWS, respectively.

PURPOSE: To review long-term outcomes of circumscribed choroidal hemangioma (CCH). METHODS: Hospital charts of all CCH cases diagnosed from 2008 to 2019 were retrospectively reviewed. RESULTS: All 172 patients were managed with either observation, transpupillary thermotherapy, argon laser photocoagulation, photodynamic therapy, plaque brachytherapy or stereotactic radiosurgery. The most common 3 modes of management were clinical observation (30.2%), transpupillary thermotherapy (52.9%) and argon laser photocoagulation (8.7%). Median follow-up time was 10 months (range: 3, 160). Anatomical outcomes were stable in 87.1% of observation group and improved in 60.5% of thermotherapy group. Quantified optical coherence tomography angiography findings showed statistical differences in vascular and perfusion densities in fellow eyes of hemangioma patients. CONCLUSION: Circumscribed choroidal hemangioma can be treated in various ways. Transpupillary thermotherapy is an anatomically effective treatment in selected cases. The diagnosis of CCH may have vascular implications in fellow eyes of the patients.

BACKGROUND: Intramuscular hemangiomas (IMH) account for 0.8 % or less of all benign soft tissue tumors in the general population. Due to their uncommon nature, especially in the head and neck, they are often misdiagnosed and not included in the differential diagnosis. METHODS: This study describes a case series of eleven pediatric patients with a diagnosis of IMH through a retrospective review of the electronic health records and archival records in the Department of Pathology at Children's Hospital of Colorado (CHCO). RESULTS: The index case had a unique presentation in the submandibular triangle, while the remaining ten cases are appendicular and thoracolumbar in nature. CONCLUSIONS: This case series contributes to the sparse scientific literature available regarding IMH, particularly in its head and neck presentation as relevant to otolaryngologists.

Infantile hemangioma (IH) is the most common benign tumor in infants and usually resolves on its own. However, a small portion of IH cases are accompanied by serious complications and other problems, impacting the physical and psychological health of the children affected. The pathogenesis of IH is highly controversial. Studies have shown that abnormal blood vessel formation is an important pathological basis for the development of IH. Compared with that in normal tissues, the equilibrium of blood vessel growth at the tumor site is disrupted, and interactions among other types of cells, such as immune cells, promote the rapid proliferation and migration of vascular tissue cells and the construction of vascular networks. Currently, propranolol is the most common systemic drug used to inhibit the growth of IHs and accelerate their regression. The purpose of this review is to provide the latest research on the mechanisms of angiogenesis in IH. We discuss the possible roles of three major factors, namely, estrogen, hypoxia, and inflammation, in the development of IH. Additionally, we summarize the key roles of tumor cell subpopulations, such as pericytes, in the proliferation and regression of IH considering evidence from the past few years, with an emphasis on the possible mechanisms of propranolol in the treatment of IH. Angiogenesis is an important event during the development of IH, and an in-depth understanding of the molecular mechanisms of angiogenesis will provide new insights into the biology and clinical treatment of IH.

Focal liver lesions (FLLs) have become an increasingly common finding on abdominal imaging, especially asymptomatic and incidental liver lesions. Gastroenterologists and hepatologists often see these patients in consultation and make recommendations for management of multiple types of liver lesions, including hepatocellular adenoma, focal nodular hyperplasia, hemangioma, and hepatic cystic lesions including polycystic liver disease. Malignancy is important to consider in the differential diagnosis of FLLs, and healthcare providers must be familiar with the diagnosis and management of FLLs. This American College of Gastroenterology practice guideline uses the best evidence available to make diagnosis and management recommendations for the most common FLLs.

BACKGROUND Hemangiomas of the adrenal gland are rare benign non-functional tumors arising from the gland's vascular endothelium. Adrenal hemangiomas are rare in clinical settings, often discovered incidentally during an unrelated diagnostic investigation. CASE REPORT A 39-year-old man presented with a heterogeneous, enhancing 4.56×4.24×3.9-cm mass originating from the right adrenal gland's lateral limb, discovered incidentally on computed tomography (CT) to investigate renal colic. He was routinely followed up for 2 years with serial CT scans; the mass exhibited considerable growth compared with baseline, with a relatively stable appearance with hyperdense soft tissue component, fat, and foci of calcification. Dexamethasone suppression test demonstrated suppressed cortisol response, indicating a non-functional mass. Therefore, laparoscopic right adrenalectomy was performed, owing to the benign nature of the preoperative diagnosis of myelolipoma and mass size. The patient experienced an uneventful recovery, with no perioperative complications. The resected mass was 5×4×4 cm in size and weighed 30 g. Histopathology confirmed adrenal hemangioma. Serial sectioning revealed an encapsulated lesion with heterogeneous solid and cystic surfaces. Light microscopy examination showed dilated and congested vascular channels lined by flattened endothelium. Focal mature adipose tissue was seen. CONCLUSIONS The infrequent occurrence of adrenal hemangiomas and their nonspecific clinical and radiological presentation results in a considerable diagnostic challenge and, often, misdiagnosis. Surgical resection is usually necessary to exclude malignant disease, alleviate pressure-related symptoms, and decrease risk of retroperitoneum hemorrhage. These lesions are associated with a good prognosis. One limitation of this report is the lack of preoperative adrenal magnetic resonance imaging of the incidental adrenal mass.

OBJECTIVES: To evaluate the various skin conditions diagnosed in intensive care unit (ICU) patients. METHODS: This is a descriptive retrospective study of all adults, pediatric, and neonatal patients who were admitted to the ICU and had a dermatological manifestation during hospital stay or patients who had dermatological condition that requires ICU admission. All skin conditions were categorized and analyzed. RESULTS: A total of 344 ICU patients with 365 different dermatological conditions were included in the study. The age of patients ranged from less than 1-96 years, with a mean age of 43.6±30.1 years. Of the patients, 189 (54.9%) were males. The top 3 general disease categories observed were skin infections, inflammatory and autoimmune diseases, and drug reactions. The most commonly reported dermatological disorders included morbilliform drug eruption (6.8%), contact dermatitis (6.3%), vasculitis (5.5%), herpes zoster (4.6%), purpura due to thrombocytopenia (3.8%), dermatitis/eczema (3.8%), candidiasis (3.8%), infantile hemangioma (2.7%), unclassified drug reaction (2.5%), intertrigo (2.5%), and herpes simplex virus (2.5%). CONCLUSION: Dermatological disorders can occur at various levels of severity in the ICU. Skin infections, inflammatory and autoimmune diseases, and drug reactions were found to be the most prevalent conditions.

BACKGROUND: Synovial hemangiomas are rare benign vascular anomalies surrounded by a synovial lining and were first described by Bouchut in 1856. These neoplasms can develop in the intra-articular region, resulting in effusions and knee pain. However, their cause remains unknown. Prompt diagnosis and intervention are critical to prevent chondral damage. Histopathological examination is used to achieve the diagnosis, which is often delayed because of a lack of specific clinical signs. This report describes a unique case in which a painful infrapatellar mass was diagnosed as a synovial hemangioma. The absence of typical magnetic resonance imaging (MRI) findings highlights the importance of arthroscopic excision for diagnosis and symptom relief. CASE PRESENTATION: A 20-year-old woman presented with persistent anterior left knee pain that became exacerbated when she climbed stairs. Despite previous pain management and physical therapy, she developed a painful lump beneath her patella that worsened over time. She had also undergone arthrocentesis, but this did not relieve her pain. Physical examination revealed a palpable, immobile 5-cm mass along the patellar tendon with limited knee flexion and extension and normal ligament stability. T1-weighted fat-saturated MRI of the left knee with gadolinium-based contrast revealed a lobulated intra-articular mass in Hoffa's fat pad that resembled a soft tissue chondroma. A biopsy of the mass was performed to provide histopathological evidence, confirming the benign nature of the mass. The subsequent excisional arthroscopy, combined with incision enlargement for mass removal, confirmed the histopathologic diagnosis of synovial hemangioma based on the presence of numerous dilated blood vessels and venous proliferation within sections of the synovium. Recovery was complete, and no residual tumor was detected on follow-up MRI after 1 year. CONCLUSION: This case study emphasizes the importance of arthroscopic excision over open surgery for patients with synovial hemangioma. The minimally invasive nature of arthroscopy combined with the well-encapsulated nature and location of the mass facilitates complete resection.

Infantile hemangioma is a benign vascular tumor, the most common in childhood, whose natural evolution is the disappearance of the lesion in the pediatric age and which has effective and safe treatments that limit its growth and favor its disappearance at younger ages. Infantile hemangioma continues to be a reason for attention to complications, due to erroneous diagnoses, lack of knowledge of the condition, late referral or fear of the effects of the medications used for its treatment. Furthermore, its presence is normalized without taking into account that it can cause uncertainty, anxiety, feelings of guilt and, as a consequence, a significant impact on the quality of life, mainly in the parents or caregivers of the child. The need for a clinical practice guideline in our country arises from the high presentation of late-remitted complications in infantile hemangioma even with the availability of adequate treatments, the continuous evolution of medicine and the appearance of new evidence. Throughout the guide you will find recommendations regarding the diagnosis, treatment and follow-up of patients with infantile hemangioma, taking into account the paraclinical tests that can be performed, topical or systemic management options, as well as adjuvant therapies. For the first time, objective tools for patient follow-up are included in a guide for the management of infantile hemangioma, as well as to help the first contact doctor in timely referral.
El hemangioma infantil es un tumor vascular benigno, el más frecuente de la infancia, cuya evolución natural favorece la desaparición de la lesión en la misma edad pediátrica y que cuenta con tratamientos eficaces y seguros que limitan su crecimiento y favorecen su desaparición a edades más tempranas. Continúa siendo motivo de atención de complicaciones, debido a diagnósticos erróneos, desconocimiento del padecimiento, referencia tardía o temor de los efectos de los fármacos utilizados para su tratamiento. Además, se normaliza su presencia sin tomar en cuenta que puede llegar a causar incertidumbre, ansiedad, sentimientos de culpa y, como consecuencia, importante afectación de la calidad de vida, principalmente en los padres o cuidadores del niño. La necesidad de una guía de práctica clínica en nuestro país surge ante la alta presentación de complicaciones del hemangioma infantil referidas de manera tardía aun con la disponibilidad de tratamientos adecuados, la evolución continua de la medicina y la aparición de nueva evidencia. A lo largo de la guía se encontrarán recomendaciones en relación con el diagnóstico, el tratamiento y el seguimiento de los pacientes con hemangioma infantil, tomando en cuenta los paraclínicos que pueden realizarse, las opciones de manejo tópico o sistémico, y las terapias adyuvantes. Por primera vez se incluyen en una guía para el manejo del hemangioma infantil herramientas objetivas para el seguimiento de los pacientes, así como para ayudar al médico de primer contacto en su referencia oportuna.

Secondary neoplastic lesions in lymph nodes are predominantly metastases from solid tumors, whereas primary lymph node hemangiomas are exceptionally uncommon, with only 24 well-documented cases in the literature. Histologically, they are characterized by endothelial cells that may appear flattened or enlarged, with variable vascular density, and the presence of stromal elements. Notably, the concurrent presence of a primary hemangioma and a metastasis from breast cancer - the latter being the most prevalent secondary lesion in axillary lymph nodes - represents an unprecedented observation. The unique case presented herein underscores the exceptional rarity of primary lymph node hemangiomas and demonstrates for the first time their possible coexistence with breast cancer metastasis within the same axillary lymph node. In sharing and discussing this case study, we pay homage to Professor Juan Rosai, whose work in redefining rare and complex diagnoses continues to enlighten our understanding of lymph node vascular lesions.

Systemic lupus erythematosus (SLE) is usually regarded as a relative contraindication for deceased kidney donation. The pathological variations because of the changes in the immune environment after kidney transplantation (KT) are unclear, and the recovery of renal function is poorly understood. We present a case of KT from a deceased donor with SLE who was followed-up for one year. Although SLE-related hemangioma developed during the perioperative period, it was cured after interventional treatment. A pre-planned biopsy was performed one year after KT, and it was found that most of the pathological changes and immunofluorescent markers of lupus had resolved. Renal function was stable, and urinary protein and occult blood levels reduced one year after KT.
