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.
