Lobular Capillary Hemangioma of the Buccal Mucosa: A Rare Presentation.

Hemangiomas are benign vascular tumours of the head and neck. Lobular capillary hemangioma (LCH) is a common, acquired proliferative reaction in vascular tissue. It has female predilection, and peak incidence occurs in adolescents and young adults. Histopathologically, it is characterised by nodular proliferation of capillary-sized vessels lined by endothelial cells with plump nuclei. The capillary lumen shows the presence of numerous erythrocytes. To distinguish this lesion from other vascular lesions, a precise diagnosis is required. The majority of oral hemangiomas will regress without any treatment. If these tumours continue into adulthood, it may lead to difficulty in speech and swallowing. This case report presents an atypical manifestation of LCH of the buccal mucosa in a 51-year-old male patient.

Microsurgical treatment of spinal intradural capillary hemangioma: A consecutive case series of 18 patients and literature review.

PURPOSE: Intradural capillary hemangioma is a rare condition with unclear etiology. Although intradural capillary hemangiomas are benign, they exhibit significant proliferative activity, and their clinical significance should not be underestimated. METHODS: We report a series of spinal intradural capillary hemangiomas to illustrate the characteristics, surgical management, and outcomes. METHODS: A total of 18 consecutive patients who underwent microsurgical treatment were retrospectively reviewed. Patient characteristics were recorded in each case, including presenting symptoms, imaging findings, neurologic status, a surgical procedure performed and follow-up. RESULTS: There were 11(61.1 %) male and 7(38.9 %) female patients, with the ages ranging from 25 to 62 years. The thoracic spine was the most commonly affected site, accounting for 77.8 % (14/18) of the cases. 9 tumors were identified as intradural extramedullary, 3 tumors as intramedullary, and 2 tumors as both extramedullary and intramedullary. There were also 4 cases of tumors localized to the cauda equina. Clinical presentations included back pain, sensory deficits, weakness and gait ataxia with a duration of symptoms ranging from 1 to 12 months. The lesion was hypointense or isointense with the spinal cord on T1- weighted images and hyperintense on T2-weighted images and showed intense enhancement after contrast medium injection. All patients underwent surgical treatment, and no significant postoperative complications were observed. Postoperatively, patients were followed up for an average of 44 months. Follow-up showed that the majority of patients experienced significant improvement in neurological function, with no cases of recurrence. CONCLUSION: Surgical resection is typically the preferred method for treating spinal intradural capillary hemangiomas. Complete resection can relieve spinal cord compression and minimize the risk of recurrence.

Mediastinal Hemangioma Mimicking as Bronchial NET.

We present a rare case of mediastinal capillary hemangioma in a 54-year-old female. She presented with back pain in the left suprascapular region, and the chest radiograph revealed left pleural effusion. On further workup with high-resolution computed tomography (CT) chest, a hypervascular pleural-based neoplastic lesion in the left upper hemithorax with gross left pleural effusion and subtotal collapse of the left lung was identified. 18F-fluorodeoxyglucose positron emission tomography/CT was suggestive of a weakly metabolic well-defined pleural-based soft tissue lesion in the left upper hemithorax along the mediastinal side. Neuroendocrine tumor was suspected. 68Ga-DOTATATE PET/CT was advised, which showed intense uptake in the lesion. The mass was resected completely. Histopathological examination established the final diagnosis as benign vascular tumor consistent with a capillary hemangioma.

Port-Wine Stains and Intraoral Hemangiomas: A Case Series.

Port-wine stains (PWSs), also called port-wine birthmarks or nevus flammeus, are hamartomatous vascular capillary malformations that clinically appear as erythematous areas on the buccal mucosa, vermilion border of the lip, gingiva, or pink to port-wine-colored patches on skin since birth and persist throughout life. On the face, they occur in the area supplied by the trigeminal nerve. PWSs have structural abnormalities of the intradermal capillaries. PWSs on the skin and oral mucosa contain ectatic capillaries in the dermis and submucosa, respectively. PWSs occur anywhere, and the oral mucosa is no exception. PWSs on the facial skin lead to cosmetic disfigurement and create social stigma. Clinically, PWSs start as flat, pink, or red patches and may darken, thicken, and develop nodules over time. The diagnosis of PWSs is primarily clinical. PWSs are complex vascular malformations with significant clinical, psychosocial, and therapeutic challenges. This article enlightens a series of cases of PWSs on the facial skin and capillary hemangioma on the gingiva, buccal mucosa, and lip diagnosed by a diascopy test, etiopathogenesis, differential diagnosis, and management of PWSs.

MR Imaging of Typical Ovarian Hemangioma: A Case Report.

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.

Ovarian hemangioma: A rare encounter.

Ovarian hemangioma, though rare and asymptomatic, can mimic malignant ovarian tumors, thus it is necessary for comprehensive histopathological and immunohistochemical evaluation for accurate diagnosis and appropriate management.

The First Case of Eruptive Pyogenic Granuloma following COVID-19 Vaccination.

Introduction: Pyogenic granuloma presents clinically as a rapidly growing, friable, red papule of skin or mucosa, commonly measuring less than 10 mm with frequent bleeding due to ulceration. Angioproliferative diseases including pyogenic granuloma and cherry angioma have been reported during COVID-19 infection or following COVID-19 vaccination. Case Presentation: Here, we report a 52-year-old female patient who developed diffuse skin eruptions 3 weeks after the second dose of COVID-19 vaccination. Conclusion: As per our knowledge, this is the first case of eruptive PG following COVID-19 vaccination. Oral propranolol and PDL laser therapy were administered after obtaining inconvenient results from electro-cautery, and there was a good response within 6 weeks of starting therapy, defined by the cessation of new lesion formation and a decrease in the size of large lesions.

Spontaneous multifocal pyogenic granulomas.

Cutaneous pyogenic granulomas (PGs) are common, benign vascular tumors of uncertain pathogenesis; however, a growing body of literature suggests that the formation of PGs may be secondary to genetic alterations in both the Ras/Raf/MAPK and PI3K/Akt/mTOR pathways. We present three cases of spontaneous multifocal PGs that first presented in infancy, were not associated with other vascular anomalies or discernable etiology, harbored somatic genetic variants in the Ras/Raf/MAPK pathway (NRAS n = 2, FGFR1 n = 1), were refractory to treatment with beta-blockers and mTOR inhibitors, and responded best to pulsed dye laser. We propose the term "spontaneous multifocal PGs" to describe this entity.

A 24-year-old patient with testicular benign capillary hemangioma: A rare case report.

Key Clinical Message: The importance of urologists and pathologists being knowledgable about primary testicular hemangiomas and other benign adult testicular neoplasms, though rare, is crucial. Ensuring these professionals are well-versed in these conditions is vital in medicine. Testicular sparing surgery, especially when tumor markers are negative, is a common approach for patients with small or uncertain testicular masses. Abstract: The cause of the uncommon benign testicular tumor known as testicular capillary hemangioma is currently unclear. Children are shown to have a greater incidence than adults. Histopathological examination reveals a vascular tumor with a well-formed capillary lumina. The lesions are bordered by flattened endothelium and have lobulated clusters of closely spaced capillaries with an abundance of vascular gaps. These capillaries have anaplastic characteristics and lack mitotic activity. The patient, who was 24-year-old, came to the urology department complaining of severe testicular pain. He had no significant medical history. Clinical examination found a mass at the upper pole of the testicle. An ultrasonography Doppler study found a left varicocele that measured 3.5 mm in diameter, as well as a mass at the upper part of the left testicle. Pathologic examination confirmed the presence of a benign hemangioma with. Although rare, it is important for urologists and pathologists to be aware of primary testicular hemangiomas and other benign adult testicular neoplasms. Testicular sparing surgery has always been considered in patients with small or indeterminate testicular masses with negative tumor markers.
