Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson tumor, is a rare vascular benign tumor of blood vessels. It may occur in any part of the body, especially the deep dermis and subcutaneous tissue of the head, neck, fingers and trunk. The imaging and histopathology of IPEH are similar to hemangiosarcoma, especially in the case of active vascular endothelial hyperplasia. IPEH is a reactive proliferative lesion of vascular intima. The etiology is still unclear. After some studies showed that IPEH was a benign lesion, few reports on the etiology of it were reported. IPEH is usually limited to the thrombotic vessels or lumens of vascular malformations, usually accompanied by a clear history of trauma. IPEH usually does not cause any symptoms. It looks like a slow-growing lump. Some cases have been reported with pain and swelling. Although IPEH is relatively rare, its accurate diagnosis is crucial because it may be similar to malignant angiogenic lesions in clinical practice. There were few reports of cases related to intravascular papillary endothelial hyperplasia located in the sternocleidomastoid muscle after reviewing the domestic and foreign literature in recent 10 years. This case reports that a young male, who was admitted to the hospital one month after finding a subcutaneous tumor in the left neck. After admittance, relevant preoperative examinations were completed. After multi-disciplinary discussion and elimination of surgical contraindications, a specific surgical plan was formulated. The tumor was removed under local anesthesia on the second day after admission. During the operation, it was found that the tumor was located between the sternocleidomastoid muscle bundles, and it was sent for pathologic examination. Paraffin section pathology was reported after operation. Histological examination showed that the morphology was consistent with vascular endothelial papillary hyperplasia. There were no related surgical complications and recurrence in the 3-month follow-up. The purpose of this paper is to provide clinicians with a certain understanding of this rare disease through the report of this case of IPEH, and to identify it in later clinical work, and at the same time, to avoid confusion with malignant diseases, such as hemangiosarcoma, leading to unnecessary treatment and increase the cost of treatment.

Separation of vascular lesions into one of the two groups, namely, hemangioma and vascular malformations can be of considerable significance relative to the treatment of patients. They pose serious bleeding risks. A case report is presented here where a patient with a vascular malformation is treated with fixed orthodontic appliances. A coordinated, interdisciplinary approach can result in enhanced patient satisfaction and successful treatment outcomes.

Chorangiosis is a placental vascular abnormality characterized by excessive capillarization in terminal chorionic villi, often associated with chronic placental hypoxia. It is observed in 5%–7% of placentas from neonates admitted to neonatal intensive care units and correlates with adverse maternal and fetal outcomes. We report a case of a chorangiosis of the placenta revealed in an 18-year-old primigravida who presented with moderate anemia, fetal growth restriction, oligohydramnios, and underwent elective cesarean section at 36 + 5 weeks. Chorangiosis has been linked to adverse outcomes, including stillbirth and maternal morbidity. This case highlights the importance of considering chorangiosis in the differential diagnosis of placental lesions with atypical ultrasound features. Early recognition, close fetal surveillance, and timely delivery are crucial for optimizing perinatal outcomes in such scenarios.

Infantile hemangiomas are known to be the most common tumors of childhood. These vascular tumors have a distinctive clinical course characterized by a proliferation phase (early and late), followed by a plateau phase and lastly the involution phase. Despite the ability to involute, certain complications, ulcerations being the most common, indicate prompt treatment. Early intervention during the proliferative phase with oral propranolol has been emphasized to achieve an optimum outcome. In this case, a 7-month-old infant presented with a 4.4cm by 3.2cm infantile hemangioma (IH) with ulceration on the left intergluteal area during the late proliferative phase. Prior to propranolol treatment, routine laboratory workup, 21-lead electrocardiogram and ultrasound of the kidneys, ureter and bladder were done, revealing unremarkable results. The patient was referred to a Pediatric Cardiologist and assessment deemed no contraindications for beta-blocker treatment. That patient was placed on a 12-hour day admission for the initiation of oral propranolol at a starting dose of l.0mg/kg/dose and was later discharged, stable, at 1.5mg/kg/dose. Escalation of doses were done by 0.5 every 2 weeks under close supervision on subsequent follow-ups via telemedicine. Four months following the initiation of propranolol treatment regression of the size of the lesion with residual fibrosis were observed. Oral propranolol appears to be an effective and safe therapeutic approach for ulcerated infantile hemangiomas, even during the late proliferative phase. Results achieved significant contraction and resolution of the ulceration and rapid involution of the lesion.

Glottic hemangioma is a benign vascular tumor that is rarely seen in the adult population. We report a rare Filipino case of glottic hemangioma in a 65-year-old female presenting with 2 weeks history of hoarseness and a smooth, pedunculated, bluish mass at the anterior one-third of the right vocal cord in flexible laryngoscopy. Direct suspension laryngoscopy showed a pedunculated mass that was paler-looking, similar to the color of the surrounding mucosa, exhibiting the Phonation sign of Menzel. The patient underwent microlaryngeal excision and histopathology showed findings consistent with cavernous hemangioma.

The three-day-old female infant was admitted to the hospital due to respiratory distress after birth. She was born premature at 36⁺² weeks gestational age. Prenatal ultrasound suggested abnormal development of the fetal liver vessels, and she had dyspnea that required respiratory support after birth. Chest X-ray indicated an enlarged cardiac silhouette, and cardiac ultrasound revealed enlargement of the right atrium and right ventricle. Diagnosis of hepatic hemangioma with arteriovenous fistula was confirmed through liver ultrasound and abdominal enhanced CT. At 19 days old, she underwent ligation of the hepatic artery under general anesthesia, which led to an improvement in cardiac function and she was subsequently discharged. Genetic testing revealed a mutation in the ACVRL1 gene, which was inherited from the mother. The article primarily introduces a case of neonatal heart failure caused by hepatic hemangioma with arteriovenous fistula, and multi-disciplinary diagnosis and treatment of this disease.

Infantile hemangiomas are relatively common soft tissue tumors in infants and young children, with a prevalence of about 4.5% in full-term newborns. Subglottic Hemangioma （SGH） is a relatively rare type of hemangioma, and its special location often causes respiratory distress and potentially life-threatening conditions in infants. Therefore, it is necessary for clinicians to make an accurate diagnosis and formulate a detailed treatment plan based on the clinical manifestations, the auxiliary examinations, the medical history and the vital signs evaluation of patients.This review describes the pathophysiological mechanism of infantile hemangioma and provides a detailed discussion on commonly used treatment methods in detail.
