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.

Adult transverse sinus capillary hemangioma: case report and review of the literature.

BACKGROUND: Adult intracranial capillary hemangioma (ICH) is an extremely rare disease with very few cases reported in the literature. Natural history is poorly understood and therapeutic management has not been clearly defined. METHODS: Using PRISMA guidelines, we systematically reviewed all published adult cases of ICH, to which we added our own case. CASE PRESENTATION: A 24-year-old patient with intracranial hypertension underwent stenting for left transverse sinus ICH. Recurrence was managed by subtotal resection, and radiotherapy was undertaken after a second relapse. Radiotherapy achieved complete response at last follow-up. RESULTS: Among cases of ICH found in the literature, 36 concerned adults (55.3%), with clear female predominance, and only 2 cases affecting the transverse sinus (8.1%). Adult ICHs grew over time, and pregnancy seemed to accelerate natural progression. Complete resection was achieved in most cases, and radiotherapy was used in case of relapse, with high rates of tumor control. CONCLUSION: Transverse sinus ICH is uncommon, and venous stenting is a suitable option in case of tumor invasion to treat intracranial hypertension. Surgery is the gold-standard treatment, and radiotherapy is a very effective alternative, with high rates of tumor control. Natural history is not benign, particularly in case of pregnancy.

Management of Lobular Capillary Hemangioma Using Diode Laser: A Case Report.

This case report focuses on the clinical development of a 32-year-old female patient's lobular capillary hemangioma and provides valuable insights into the atypical nature of this tumor. Low-level laser therapy (LLLT) that follows diode laser intervention can be regarded as a novel and evidence-based approach to therapeutic management. The application of a diode laser causes the vascular elements that comprise the bulk of the lesion to coagulate, which in turn causes the lesion's size to decrease. The biological processes that lead to quick tissue regeneration are also activated by LLLT. The suggested therapeutic approach ensures that the patient will heal in the best possible way while also optimizing their comfort and safety. It extends beyond the mere removal of wounds. The case report demonstrates how well dual laser therapy works to lessen common postoperative issues that are commonly seen in traditional surgical therapies for lobular capillary hemangioma such as excessive bleeding and infection. The precise application of the diode laser minimizes damage to surrounding tissues, thereby enhancing the healing process. Additionally, following surgery, LLLT helps reduce pain and inflammation, which improves patient outcomes. The potential of diode laser and LLLT therapies for treating vascular lesions, including lobular capillary hemangioma, is evidenced by their therapeutic advantages. This encourages wider clinical applications and field research. The presented case report offers valuable clinical significance by highlighting an innovative therapeutic approach for lobular capillary hemangioma, a vascular lesion that can present challenges in management.

Residual Recurrence of a Small Intestinal Capillary Hemangioma with Obscure Gastrointestinal Bleeding Treated by Double-Balloon Endoscopy: A Case Report and Literature Review.

An 86-year-old man presented with anemia. He underwent abdominal contrast-enhanced computed tomography, gastroscopy, and colonoscopy without any bleeding detected. Small bowel capsule endoscopy (SBCE) revealed a reddish polypoid lesion with blood oozing into the jejunum. Antegrade double-balloon endoscopy (DBE) revealed a 5 mm sized protrusion into the jejunum. Endoscopic mucosal resection (EMR) was difficult; the lesion was snared and resected before energization. Clips prevented further bleeding and the lesion's position was marked with a tattoo. Histopathological examination of the lesion led to a diagnosis of capillary hemangioma. After 11 months, the patient was again anemic. A reddish polypoid lesion oozing blood near the tattoo was found by SBCE. Another antegrade DBE showed a 7 mm sized protrusion near the tattoo. The lesion was successfully treated by EMR. Histopathological examination revealed the residual recurrence of a small intestinal capillary hemangioma. The patient recovered from anemia after the EMR. Two months later, SBCE showed no findings around the tattoo. Hemangiomas account for 7-10% of benign small intestinal tumors; most are cavernous hemangiomas, and capillary hemangiomas are rare. We report a rare case of a recurring small intestinal capillary hemangioma detected by SBCE and treated using DBE. We also review the literature.

Solitary pulmonary capillary hemangioma - An underrecognized rare tumor. Report of 32 new cases with literature review.

OBJECTIVE: To explore the clinical, imaging, pathologic characteristics and differential diagnosis of solitary pulmonary capillary hemangioma (SPCH). METHODS: Thirty two cases of SPCH were collected and studied, with literature review. RESULTS: This study included 13 males and 19 females, with a male-to-female ratio of 1:1.5. The age ranged from 26 to 70 years (median age of 43 years). All patients were asymptomatic at presentation. Lung nodules were incidentally discovered during chest computed tomography (CT). Imaging features included 21 cases with partial solid nodules (PSN), 7 cases with ground-glass nodules (GGN), and 4 cases with solid nodules (SN). Eleven cases were in the left lung lower basal segment, 11 cases in the right lung lower basal segment, 6 cases in the right lung upper anterior segment, and 4 cases in the right lung middle lateral segment. The lower basal segments of the lungs were involved in 22 (11 in each lung) cases (22/32, 68 %). The tumors ranged from 6 to 18 mm (average 10 mm). Macroscopically, 16 cases had clear boundaries, while 16 cases had unclear boundaries, and gray-red or dark brown on cut surfaces. Intraoperative frozen section was performed in 27 cases, with diagnosis of SPCH in 12 and pneumonia or inflammatory lesion in 15. Microscopically, the nodules were composed of densely proliferated and dilated capillaries. The capillary walls were lined with a single layer of flat endothelial cells, without atypical features. Collapsed alveolar septa were replaced by a large number of capillaries. All cases showed proliferating capillaries spreading into the walls of small veins/arteries and bronchi, with 3 cases showing dilated capillaries protruding into the bronchiolar lumens as polyp-like structures. Twenty-six cases (26/32, 81 %) showed proliferating capillaries passed over the interlobular septa. Twenty-six cases (26/32, 81 %) showed irregular intimal thickening of small muscular arteries in the peripheral areas of the lesions, with the thickened intima being cellular or fibrous. In twenty-seven cases (27/32, 84 %) the lesions were located in the subpleura, with 6 cases involving the pleura. CONCLUSION: SPCH is a rare benign lung tumor that mostly occurs in the lung lower basal segments with predominance in females. It usually appears as a ground-glass nodule on CT and is very similar to early-stage lung cancer. Accurate diagnosis requires collaboration of radiologists, surgeons, and pathologists. SPCH should be regarded as an important differential diagnosis of small incidental lung nodules.

Lobular capillary hemangioma post-chemotherapy for T-cell leukemia treated with an antibiotic: a case report.

Background: Lobular capillary hemangioma, also known as pyogenic granuloma (PG), is a relatively common benign rapidly growing friable vascular tumor of the skin and mucus membranes. Although the exact pathogenesis of PG is unknown, many theories discussed the potential of an angiogenic stimulus and an imbalance of inducers and inhibitors triggering the hyperplastic and neovascular response. The most frequently used modality for treatment of PG is surgical treatment. The proposed case represents an unexpected evolution to a possible therapeutic measure. Case Description: We represent a case of a 32-year-old male, known to have T-cell acute lymphoblastic leukemia treated successfully with chemotherapy, currently maintained on methotrexate (MTX) 40 mg and 6-mercaptopurine, 100 mg, presented with 1-month history of painful rapidly growing ulcerated nodules on his right-hand palm and middle finger. Both skin lesions developed approximately 3 months following patient initiation of maintenance treatment. Physical examination revealed two crusted nodules. A proximal lesion was observed over the palmar aspect between the second and third fingers, with the other one occurring alongside the distal phalanx of the third finger, measuring 2.5 cm × 1.5 cm, and 2.5 cm × 3.5 cm respectively. Skin biopsy was obtained from both lesions. The results of the histologic examination both revealed inflamed PG. Tissue cultures of both specimens tested positive for Pseudomonas aeruginosa growth while no fungal and tuberculosis were cultured. Ciprofloxacin 500 mg twice daily, a 2-week course was started. Both lesions completely resolved at 10th-day of antibiotic course with no recurrence. Conclusions: This is a case of a patient with lobular capillary hemangioma of the hand treated successfully with no recurrence using an oral antibiotic. The proposed case represents an unexpected evolution to a possible therapeutic measure. The unexpected role of a conservative measure rather than the conventional surgical method in treating vascular tumors has been highlighted. Moreover, the contribution to an excellent cosmetic outcome has also been demonstrated.

A Review of the Current State and Future Directions for Management of Scalp and Facial Vascular Malformations.

Vascular malformations are structural abnormalities that are thought to result from errors in vasculogenesis and angiogenesis during embryogenesis. Vascular malformations of the scalp present unique management challenges due to aesthetic and functional implications. This review examines the pathophysiology, clinical presentation, and management techniques for six common types of vascular malformations of the face and scalp : infantile hemangioma, capillary malformations, venous malformations, lymphatic malformations, arteriovenous malformations, and arteriovenous fistulas. These lesions range from common to rare, and have very different natural histories and management paradigms. There has been increasing understanding of the molecular pathways that are altered in association with these vascular lesions and these molecular targets may represent novel strategies of treating lesions that have historically been approached from a structural perspective only.

Challenges and Management of Capillary Intraosseous Hemangioma in the Mandibular Symphysis: A Case Report.

Capillary intraosseous hemangioma is a benign vascular neoplasm that affects bone tissue, yet its occurrence in the jaw bones has been seldom reported in the literature. We present a case of a capillary intraosseous hemangioma located in the mandibular symphysis of a 28-year-old male. Initially addressed by the patient's dentist as an infectious lesion of endodontic origin, the sudden worsening of the condition, marked by the development of a rapidly expanding exophytic mandibular lesion and tooth mobility, led to the consideration of various potential diagnoses. Subsequently, an incisional biopsy was performed, triggering multiple episodes of recurrent bleeding, leading to several visits to the emergency department, and prompting an urgent status upgrade for the patient. Upon the histological diagnosis of vascular neoplasm, the patient underwent the excision of the lesion, with a favorable and uneventful evolution, although with expected sequelae. As a result, a temporary prosthetic solution, comprising a Maryland Bridge, was implemented, with plans for guided bone regeneration and implant-supported fixed dental prostheses currently in progress. This case underscores the diagnostic and therapeutic challenges associated with this rare condition. Consequently, achieving the optimal outcome for the patient largely depends on a multidisciplinary approach, emphasizing the critical importance of thorough preoperative assessment, along with a well-devised treatment plan and rapid intervention.

A case report of lobular intradural extramedullary capillary hemangioma in a 14-year-old patient: resection and reconstruction.

Background: Intradural, extramedullary capillary hemangiomas of the cauda equina are exceedingly rare malformations arising from the endothelial cells of the nervous system vasculature. Roughly 20 cases have been reported in the literature, with the youngest and only pediatric case being in a 17-year-old patient. We report the youngest case of intradural extramedullary capillary hemangioma of the cauda equina in a 14-year-old patient. Case Description: A 14-year-old female presented with two-month history of low back pain with bilateral leg pain and numbness. Magnetic resonance imaging (MRI) revealed an L2 well-defined homogenous contrast-enhancing intradural, extramedullary mass causing severe spinal canal stenosis. Patient underwent laminoplasty for resection of an intradural tumor. Intraoperative hemostasis was readily achieved via early identification and coagulation of the predominate feeding vessel. Postoperatively, the patient awoke with no deficits and resolved leg pain. A 3-month postoperative MRI revealed no tumor recurrence and fully healed lamina. Conclusions: Given the benign nature, the operative goal is complete excision of the tumor without damage to surrounding neural structures. Postoperatively the goal is relief of pain and improvement in neurologic function. To our knowledge we report the first case in which laminoplasty is utilized for the treatment of this pathology in a pediatric patient. Evidence for laminoplasty in this patient population is sparse and future studies are still needed. In any case, reconstruction of the surgical site in a manner that returns the patient's normal anatomy should be strongly considered especially in younger patients.

Case report: A cystic capillary hemangioma located at the conus medullaris mimicking hemangioblastoma.

Capillary hemangiomas, usually found in skin and mucosal tissues, are rarely encountered within the spinal cord, presenting a significant diagnostic challenge. We report a rare case of intradural extramedullary capillary hemangioma at the conus medullaris in a 66-year-old female patient. Our initial diagnosis leaned towards a cystic hemangioblastoma based on MRI findings due to the presence of cystic formation with an enhanced mural nodule. However, surgical exploration and subsequent pathological examination revealed the lesion as a capillary hemangioma. To the authors' knowledge, this case may represent the first documented instance of a spinal capillary hemangioma that mimics a cystic hemangioblastoma.

Thoracic Intra and Extramedullary Capillary Hemangioma with Subacute Clinical Course: A Case Report and Literature Review.

Capillary hemangiomas are benign tumors comprising a lobulated proliferation of capillary vessels frequently located in the soft tissues of the neck and head. Spinal intradural capillary hemangiomas are rare, particularly intramedullary lesions. To our knowledge, only 31 cases of spinal intramedullary capillary hemangiomas have been reported. Here, we describe a rare case of a thoracic capillary hemangioma comprising extramedullary and intramedullary components. A 51-year-old male patient presented with bilateral lower extremity numbness and subsequent paraparesis, sensory disturbance, and bladder-bowel dysfunction with a subacute clinical course. Magnetic resonance imaging revealed a mass lesion with intramedullary and intradural extramedullary components at the Th9-10 vertebrae level and widespread spinal cord edema. Contrast-enhanced computed tomography revealed abnormal vessels on the dorsal spinal cord surface. Spinal angiography revealed a light-stained mass lesion fed by the radiculopial artery from the right Th11 intercostal artery. The tumor was resected en bloc, and the histological diagnosis was a capillary hemangioma. Postoperatively, the spinal cord edema diminished, and the patient was discharged from the convalescent rehabilitation ward. Although intramedullary capillary hemangioma is a rare spinal tumor and its preoperative diagnosis is difficult, it should be considered in the differential diagnosis of spinal intramedullary tumors.

Pediatric intranasal lobular capillary hemangioma: a case report and review of the literature.

Lobular capillary hemangioma is a benign lesion commonly affecting the head and neck region. However, in children, it is commonly seen in the buccal mucosa, gingiva, and the tongue, but its presence in the nasal cavity is less frequent. The most common symptoms of nasal hemangiomas are epistaxis and nasal obstruction. However, we present a case of a thirteen-year-old male having intranasal lobular capillary hemangioma with a 2-day history of left-sided epistaxis. The diagnosis is confirmed by histological examination, and the treatment is done by endonasal endoscopic excision of the hemangioma with cauterization of the feeding vessel has performed to remove the lesion completely. Moreover, the diagnosis of lobular capillary hemangioma must always be kept in mind when discussing the differential diagnosis of a bleeding mass within the nasal cavity, even though it is a rare condition and surgical excision is still the preferred first-line treatment.

Fallopian Tube Hemangioma Discovered on Follow-up for Uterine Leiomyoma.

Hemangioma in female reproductive organs, particularly in the fallopian tube (FT), is a sporadic disease. In this report, we describe a case of hidden capillary hemangioma in FT in a 39-year-old woman who suffered from uterine leiomyoma. During the preoperative stage, pelvic sonography, computed tomography, and diagnostic laparoscopy revealed a subserous leiomyomatous nodule located along the posterior wall of the uterus. Despite this, intraoperatively, a benign vascular neoplasm was diagnosed. Histologically, it is characterized by multiple thin-walled vascular spaces lined with a single layer of endothelial cells, in which single mitoses were observed. The diagnosis was then confirmed immunohistochemically by CD31 and CD34 expression in the endothelial cells lining the inner surface of the spaces and the low mitotic activity of the tumor cells. It is virtually impossible to diagnose this asymptomatic neoplasm before and during surgery, which can result in an inadequate number of surgeries. Incorrect interpretation of a benign tumor at a young age can lead to unnecessary radical surgery with a resulting loss of fertility, and an unrevealed malignant process can threaten life.

Distal penile pyogenic granuloma: A case report.

Key Clinical Message: The mainstays of treatment for granuloma pyogenicum include careful evaluation of any penile growth, thorough excision of the polypoid, histological examination, and close monitoring to check relapse and management. Abstract: Pyogenic granuloma is an acquired noncancerous vascular proliferation that arises from the mucosa and skin, seldom subcutaneously or intravascularly. It is also referred to as telangiectasis granuloma or lobular capillary haemangioma. The risk factors include vascular abnormalities, medicines, hormones, and microtrauma. We discussed the case of a 24-year-old man who had a poorly managed ventral distal penile polypoid lesion at a peripheral hospital. Upon further histopathological examination, the diagnosis of pyogenic granuloma was made. Histopathologically speaking, the term "pyogenic granuloma" is misleading because the illness is not linked to the production of granulomas. Pyogenic granuloma's etiopathogenesis is still unknown; true hemangioma is thought to be a reactive hyperproliferative of the vasculature brought on by a variety of stimuli; pyogenic granuloma may be caused by uneven angiogenic factor production in response to minor local trauma or cutaneous disease. Histopathological analysis and surgical excision are the methods used for diagnosis and treatment. The mainstay of treatment for granuloma pyogenic granuloma includes careful evaluation of any penile growth, thorough excision of the polypoid, histological examination, close follow-up to check for relapse, and early management.

Nasal Lobular Capillary Hemangioma During Pregnancy: A Systematic Review.

Objective: To perform a systematic review of published cases of nasal lobular capillary hemangioma (LCH) during pregnancy. Data Source: PubMed, Embase, Scopus, Web of Science, and LILACS. Review Methods: We searched electronic databases from inception to June 30, 2022. Case report and case series that reported clinical data on nasal LCH during pregnancy were included. Categorical variables were expressed as proportions and numerical variables as mean ± standard deviation or median (interquartile range). Results: Twenty-three studies (20 case reports and 3 case series) involving 29 patients were included. The mean age was 30.5 ± 5.3 years. A total of 62% cases were diagnosed in the third trimester of pregnancy. The most frequent (62%) location of LCH was the nasal septum. All cases presented with epistaxis. A total of 48% cases were treated by surgical excision after delivery and the recurrence was 11%. Conclusion: Our review shows that nasal LCH during pregnancy usually manifests in the third trimester. This lesion can be treated by surgical excision with a relatively low risk of recurrence.

Intramedullary spinal capillary hemangioma with secondary neurulation defect in children.

Intramedullary spinal capillary hemangioma is a rare occurrence in pediatric patients, and only limited cases have been reported. This study presents the first two cases of spinal capillary hemangioma co-present with retained medullary cord and one case of spinal capillary hemangioma with lumbosacral lipomatous malformation. Previous literature on ten patients with this pathology was reviewed. We speculated pathogenesis, imaging features, and histopathologic findings of the disease.

Oral Pyogenic Granuloma: A Narrative Review.

Pyogenic granuloma (PG) is a benign vascular lesion found predominantly in the oral cavity. Characterized by rapid growth and propensity to bleed, PG presents diagnostic challenges due to its similarity and alarming proliferation. This narrative review synthesizes current knowledge on the epidemiology, etiopathogenesis, clinical manifestations, and management of oral PG, with emphasis on recent advances in diagnostic and therapeutic approaches. The epidemiology of the injury is meticulously analyzed, revealing a higher incidence in women and a wide range of ages of onset. It delves into the etiopathogenesis, highlighting the uncertainty surrounding the exact causal factors, although historical attributions suggest an infectious origin. It exhaustively analyzes the clinical and histopathological aspects of oral PG, offering information on its various presentations and the importance of an accurate diagnosis to guide effective treatment. It details treatment strategies, emphasizing the personalized approach based on individual patient characteristics. This comprehensive review consolidates current knowledge on oral PG, highlighting the need for further research to clarify its pathogenesis and optimize treatment protocols.

Intracranial parenchymal capillary hemangioma: A case report.

Background: Capillary hemangioma is a rare benign hemangioma that occurs in the soft tissues of the skin, orbit, head, and neck. Intracranial cases, especially intraparenchymal cases, are extremely rare. In this study, we report the course of an intracranial parenchymal capillary hemangioma with left mild motor paresis and involuntary movements of the left upper extremity and was successfully treated by surgical resection, including radiological and pathological examinations. Case Description: This is a case of a 60-year-old woman who presented with motor weakness and involuntary movement of the left upper extremity. Computed tomography and magnetic resonance imaging revealed the right frontal hemorrhagic mass lesion without enhancement of contrast medium. Cerebral digital subtraction angiography showed no vascular stain and abnormal arteriovenous shunt. Preoperatively, we diagnosed cavernous hemangioma with a hemorrhagic component located in the right motor cortex. Because this case was symptomatic, we performed a craniotomy and gross total resection of the right frontal lesion. The diagnosis of capillary hemangioma was made by histological examination, including immunohistological study. Conclusion: Because intraparenchymal capillary hemangiomas are difficult to diagnose with preoperative imaging, surgical treatment, and histopathological examination are important.

Capillary Hemangioma of the Maxillary Sinus: A Rare Cause of Massive Life-Threatening Epistaxis.

Hemangioma of the paranasal sinus is an infrequent condition. Two types of hemangioma are present at the nose; cavernous and capillary. Capillary hemangioma is rare in the sinonasal tract. Patients presented with massive epistaxis should think of nasal hemangioma. Resuscitation of patients is important and urgent Computerized Tomography scans should be performed which will help character and extension of any mass present at the nasal cavity. Initial nasal packing may help to prevent bleeding. We report a case of capillary hemangioma of a 30-year lady present with massive epistaxis initially controlled by Nasal packing. Her CT scan shows a homogenous mass at left maxillary sinuses and underwent left endoscopic sphenopalatine artery ligation and removal of the mass. Supplementary Information: The online version contains supplementary material available at 10.1007/s12070-023-04046-z.

Cavernous Sinus capillary hemangioma: Case report and literature review.

Introduction: Capillary hemangioma of the cavernous sinus is considered a benign vascular skull base tumor. In this case report, a patient with capillary hemangioma located in the cavernous sinus who was operated on with endoscopic endonasal approach is presented. Research question: What should be considered when planning the treatment for capillary hemangiomas located in the cavernous sinus? Material and methods: The treatment approaches applied in 12 patients with a diagnosis of capillary hemangioma located in the cavernous sinus, reported in the English literature, are reviewed in this article. We presented the clinical and radiological results of the treatments. Results: Cavernous sinus capillary hemangiomas are considered benign tumors. However, surgical treatment is preferred in the foreground because of the neurological deficits due to the compression effect caused by the mass. In the case reported by Masman et al. for the first time in the literature in 2021, they provided total excision with the endoscopic endonasal approach in the patient they first diagnosed by taking a biopsy with the endoscopic endonasal approach. In our case report, we provided total excision with endoscopic endonasal transsphenoidal approach. Discussion and conclusion: Many factors should be considered when deciding on the treatment method in these patients. Although radiotherapy is quite effective in the treatment of capillary hemangioma, surgery should be preferred, especially in symptomatic patients. In patients who cannot undergo surgery, radiotherapy is very valuable, although the long-term results are not yet known.
