Pediatric lobular capillary hemangioma of the nasal cavity

Rare Presentation of Bilateral Lobular Capillary Hemangioma of the Nasal Septum: A Case Report

Lobular capillary hemangioma (LCH) is a benign, rapidly growing lesion affecting the skin and mucous membranes. LCH is common in the oral cavity but is rarely observed in the nasal cavity. The disease etiology is not fully understood; however, trauma and hormonal changes are attributable factors. Patients usually present with nasal obstruction and epistaxis. This study reports the clinical picture, diagnosis, and management of a rare case of bilateral septal nasal LCH.

Endonasal Endoscopic Complete Excision of Unilateral Nasal Hemangioma in a Child: Case Report and Technical Note

Intranasal lobular hemangioma of the inferior turbinate is a rare occurrence in children. A 12-year-old girl presented with a two-month history of multiple epistaxis episodes. Contrast-enhanced computed tomography showed a large nasal mass in the right nasal cavity. Endonasal endoscopic excision of the hemangioma with cauterization of the feeding vessel was performed to remove the lesion completely. There was no recurrence at 11 months follow-up.

Intralesional Bevacizumab for the Treatment of Recurrent Sinonasal Hemangioma

INTRODUCTION:

Sinonasal hemangioma is a rare benign tumor of vascular endothelial cells. The pathogenesis is closely linked to abnormalities in the vascular endothelial growth factor signaling pathway. Multiple treatment modalities are available, though wide local excision remains the preferred treatment. Bevacizumab, an anti-vascular endothelial growth factor monoclonal antibody, has known efficacy against hemangiomas, though there are no cases of sinonasal hemangiomas managed with bevacizumab.

METHODS:

Case report.

RESULTS:

The authors review the case of a 67-year-old man with a left-sided nasal hemangioma originating from the nasal septum. He presented with progressive left nasal obstruction and recurrent epistaxis. At the time of his presentation, the lesion had recurred after 1 excision/polypectomy at an outside institution. He then underwent revision surgery via wide local excision and septoplasty. After tumor recurrence following the revision surgery, the hemangioma was noted to recur on 1 year postoperative surveillance nasal endoscopy. In-office intralesional injection of 50 mg bevacizumab was then performed under endoscopic visualization. No improvement in the tumor size was noted at 2 months after injection, with the tumor measuring 1.5 cm. At the 10-month surveillance clinical visit following injection, the tumor had dramatically involuted to 3 mm in greatest dimension. The patient reported complete resolution of his primary symptoms of epistaxis and nasal obstruction.

CONCLUSIONS:

This report demonstrates the first reported successful treatment of a sinonasal hemangioma with intralesional bevacizumab. Intralesional bevacizumab confers an additional option for adjuvant treatment of sinonasal hemangiomas. Further evaluation of intralesional bevacizumab in the treatment of these tumors is warranted.

Pedunculated cavernous hemangioma originating in the olfactory cleft

Sinonasal cavernous hemangioma is a rare condition that usually affects the lateral wall of the nasal cavity. We report the case of a 77-year-old man who presented with severe epistaxis, nasal congestion, and olfactory dysfunction. Endoscopic examination of the nasal cavity revealed the presence of a red-blue tumor that had almost completely filled the nasopharynx. Preoperatively, it was difficult to distinguish this lesion from a juvenile nasopharyngeal angiofibroma. During endoscopic surgery, the tumor was found to originate in the left olfactory cleft, and it had a long peduncle that contained blood vessels. Postoperative histopathologic examination indicated that the mass was a cavernous hemangioma. To the best of our knowledge, this is the first case of an olfactory cleft cavernous hemangioma and the first case of olfactory cleft disease associated with a cavernous hemangioma to be reported in the English-language literature.

Pediatric intranasal lobular capillary hemangioma: Report of two new cases and review of the literature

Background

Lobular capillary hemangioma (LCH) is an acquired benign vascular tumor of unknown origin. It usually affects skin and mucous membranes of the oropharynx. It rarely involves the nasal cavity which most commonly manifests as epistaxis. To our knowledge, only fifteen pediatric intranasal LCH cases have been reported in the literature. None of these occurred in the inferior turbinate. We report two new pediatric cases of LCH, one of them on the inferior turbinate and the other one on the anterior nasal septum. Our principal aim was to highlight the importance of considering this lesion as a differential diagnosis for pediatric unilateral nasal obstruction and epistaxis.

Methods

Retrospective case series and review of current literature regarding the possible causes, diagnosis, and treatment of nasal LCH.

Description of cases

Two adolescents presented with symptoms of unilateral nasal obstruction and epistaxis. Plain and contrast enhanced computed tomography revealed a well-defined intensely enhancing lesion in both cases. Patients underwent transnasal endoscopic excision and bipolar electrocautery at the base of the tumor for hemostasis. Histopathological examination confirmed the diagnosis of LCH.

Discussion

Current epidemiological and pathophysiological data suggests that the development of LCH may be associated to previous nasal trauma or endocrine disorders. LCH should be considered in the differential diagnosis of all pediatric endonasal masses associated with unilateral epistaxis and nasal obstruction. Endoscopic total excision with bipolar electrocautery for hemostasis is an appropriate treatment.

Benign sinonasal capillary haemangioma

Haemangiomas are benign fibrovascular tumours relatively that are common in the head and neck, where 60% of them occur Among the various categories of haemangiomas, lobular capillary haemangiomas (LCH) occur frequently on the skin, lips, buccal mucosa, tongue and gingiva. However, they are vanishingly rare in the paranasal sinuses. The imaging features of LCH are non-specific. The histological characteristics of LCH can also make diagnosis difficult as sometimes resemble highly vascular malignant tumours. This leads to the false preoperative diagnosis of suspected malignancy in many cases, which places the patient under unnecessary distress and anxiety. We present a case of LCH appearing as a suspicious nasal lesion of the lateral nasal wall with unilateral nasal obstruction, necrotic centre and epistaxis. The tumour was excised endoscopically in one operation including endoscopic medial maxillectomy. Further education about this lesion is deemed important as preoperative embolisation may be needed for a safe operation.

Lobular capillary hemangioma of the nasal cavity: a retrospective study of 15 cases in taiwan

BACKGROUND

Lobular capillary hemangioma of the nasal cavity is an uncommon benign vascular tumor of unknown etiology. There have been only very few case reports in Taiwan.

AIMS

This study aimed to analyze the clinical features, radiological findings, treatment modalities, and outcome of lobular capillary hemangioma treated at a teaching hospital in Taiwan during a period of 10 years.

STUDY DESIGN

Descriptive study.

METHODS

Retrospective chart reviews were performed on patients who were diagnosed with lobular capillary hemangioma of the nasal cavity at Kaohsiung Armed Forces General Hospital, Kaohsiung, Taiwan, from January 2003 to December 2012. Data retrieved included age, gender, clinical symptoms, computed tomography (CT) findings, treatment modalities, and outcome for further analysis.

RESULTS

Of the 15 patients identified, there were five males and ten females ranging from 17 to 86 years of age, with a mean age of 43.8±20.2. Epistaxis was the most common presenting symptom. All patients presented a unilateral nasal lobular capillary hemangioma. The most commonly affected site was the anterior nasal septum, followed by the inferior turbinate, vestibule, middle turbinate, and posterior nasal septum. All lesions presented as soft tissue density without bony erosions under CT examination. Endoscopic excisional surgery (n=12) or classical local excision (n=3) was performed for complete removal of the hemangioma. No evidence of recurrence was observed with 6 to 75 months of follow-up.

CONCLUSION

Lobular capillary hemangioma of the nasal cavity was usually found to occur in anterior septum with epistaxis. Complete excision with endoscopic surgery or classical local excision was recommended and recurrence can be prevented.

Routine and dynamic MR imaging study of lobular capillary hemangioma of the nasal cavity with comparison to inverting papilloma

BACKGROUND AND PURPOSE

Lobular capillary hemangioma is an uncommon lesion, and its MR imaging appearance has not been fully characterized. The purpose of this study was to determine the MR imaging features of nasal lobular capillary hemangioma and contrast its imaging characteristics to inverting papilloma.

MATERIALS AND METHODS

The MR imaging signals of 32 patients with histopathologically proven nasal lobular capillary hemangiomas and 53 patients with nasal inverted papillomas were retrospectively studied. The findings of dynamic contrast-enhanced MR imaging in 24 lobular capillary hemangiomas and in 53 inverted papillomas were also analyzed. The Monte Carlo exact test was used for comparison of the time-intensity curve patterns of lobular capillary hemangioma and inverted papilloma.

RESULTS

All lobular capillary hemangiomas appeared to be homogeneously isointense to gray matter on T1-weighted images. On T2-weighted images, all lesions showed heterogeneous hyperintensity, and a thin peripheral isointense or hypointense ring was seen in 28 patients. All lesions showed marked enhancement on enhanced images, with the exception of enhancement of the T2 isointense or hypointense ring. Forty-three (81.1%) inverted papillomas had moderate heterogeneous T2 signal intensity, and a characteristic "cerebriform" appearance was detected in 45 (84.91%) of 53 inverted papillomas. The time-intensity curves showed a washout pattern in 18 and a plateau pattern in 6 patients, whereas inverted papillomas showed a washout pattern in 12, a plateau pattern in 35, and a persistent pattern in 6 patients. There was a statistically significant difference as to time-intensity curve pattern between the 2 groups (P < .05).

CONCLUSIONS

Hyperintensity on T2-weighted images, marked enhancement of tumor with a nonenhancing thin peripheral ring, and a washout time-intensity curve pattern are characteristic MR imaging features of nasal lobular capillary hemangiomas.

Nasal lobular capillary hemangioma

Nasal lobular capillary hemangioma is a rare benign tumor of the paranasal sinuses. This lesion is believed to grow rapidly in size over time. The exact etiopathogenesis is still a dilemma. We discuss a case of nasal lobular capillary hemangioma presenting with a history of epistaxis. Contrast enhanced computed tomography of paranasal sinuses revealed an intensely enhancing soft-tissue mass in the left nasal cavity and left middle and inferior meati with no obvious bony remodeling or destruction. We present imaging and pathologic features of nasal lobular capillary hemangioma and differentiate it from other entities like nasal angiofibroma.

Nasal cavity lobular capillary hemangioma due to insect sting

INTRODUCTION

Lobular capillary hemangioma is a frequent benign vascular inflammatory lesion of the skin tissue. It rarely reaches the mucous membrane, and the nasal fossa involvement is exceptional.

CASE REPORT

A 68-year-old woman presented with an ulcerous hemorrhagic mass blocking the left nasal fossa, which had appeared a few weeks after a wasp sting in the nose. The insect was evacuated only three weeks after the sting. The clinical and radiological data suggested malignancy. Biopsy under local anesthesia proved non-contributory and was complicated by 1 week's hospitalization for severe nosebleed. Surgical excision under video-endoscopy confirmed diagnosis. At 31 months' follow-up, the patient was free of recurrence.

DISCUSSION/CONCLUSION

The pathogeny of lobular capillary hemangioma is uncertain. No previous cases affecting the mucous membrane after insect sting have been reported. Except in the typical contexts of long-term packing or pregnancy, diagnosis can be difficult and misleading. It can mimic a malignant pathology. Its rich vascularization requires caution during biopsy, and the risk of recurrence requires excision to be complete.

Pediatric nasal lobular capillary hemangioma

Background. LCH is a benign vascular growth of the skin and mucous membranes commonly affecting the head and neck. Since it was first described in the nineteenth century, this entity has been variously known as “human botryomycosis” and “pyogenic granuloma.” The shifting nomenclature reflects an evolving understanding of the underlying pathogenesis. We review the histopathology of and current epidemiological data pertaining to LCH which suggests that the development of these lesions may involve a hyperactive inflammatory response influenced by endocrine factors. We report two new cases of pediatric lobular capillary hemangioma (LCH) of the nasal cavity and review current theories regarding the etiology, diagnosis, and treatment of nasal LCH. Methods. Retrospective case series. Case Series. Two adolescent females presented with symptoms of recurrent epistaxis, nasal obstruction, and epiphora. Both patients underwent computed tomography imaging and biopsy of their intranasal mass. The tumors were excised using image-guided transnasal endoscopic technique. Seven other cases of nasal LCH have been reported to date in the pediatric population. Conclusion. Nasal LCH is a rare cause of an intranasal mass and is associated with unilateral epistaxis, nasal obstruction, and epiphora. We advocate for image-guided endoscopic excision of LCH in the adolescent population.

CT findings in two cases of lobular capillary haemangioma of the nasal cavity: focusing on the enhancement pattern

Lobular capillary haemangioma, known as pyogenic granuloma, is a relatively common benign vascular neoplasm that is composed of hyperplastic clusters of capillaries arranged in a lobular architectural pattern. Most mucosal lobular capillary haemangioma (LCH) of the head and neck arise in the oral cavity, but the nasal cavity involvement is rare. We report here on the CT imaging findings of two cases of LCH involving the nasal cavity, with an emphasis being placed on the different pattern of enhancement of the tumour on the enhanced CT scans.

A rare cause of paediatric epistaxis: lobular capillary haemangioma of the nasal cavity

The authors describe a case of a 14-year-old male child presenting with massive anterior epistaxis on a background of recurrent episodes of epistaxis. Immediate management constituted anterior nasal packing. Endoscopic nasal examination revealed a 5 mm purple vascular lesion anterior to the right-middle turbinate. The initial working diagnosis of juvenile nasopharyngeal angiofibroma which is most common in this population was excluded following MRI. The lesion was excised via an endoscopic approach with no complications. Histological analysis confirmed the diagnosis of lobular capillary haemangioma. The patient made an uneventful recovery and remains on follow-up with no recurrence.

CT features of lobular capillary hemangioma of the nasal cavity

BACKGROUND AND PURPOSE

Lobular capillary hemangioma is a benign capillary proliferation of unknown etiology. To our knowledge, no comprehensive review of imaging findings of LCHNC has been presented. Thus, we investigated characteristic CT features of LCHNC.

MATERIALS AND METHODS

This retrospective study included 6 patients (2 men and 4 women; age range, 30-65 years; mean age, 49.2 years) with histologically proved LCHNC. We evaluated the size, site of origin, attenuation on NECT, degree and pattern of enhancement, and bony changes.

RESULTS

The LCHNC lesion was 13.0-45.0 mm (average, 25.0 mm) in diameter. These lesions arose from the inferior turbinate in 5 (83.3%) patients and the anterior nasal septum in 1 (16.7%). Compared with the masticator muscles, the LCHNC lesion was hypoattenuating in 2 (33.3%) and isoattenuating on NECT in 4 (66.7%) patients. In 5 (83.3%) patients, the LCHNC lesion consisted of 2 distinct areas on CECT: a lobular intensely enhancing mass and an iso- or hypoattenuating cap of variable thickness around the intensely enhancing mass. Bony changes included erosion in 3 (50.0%) and displacement in 2 (33.3%) patients.

CONCLUSIONS

CT features of LCHNC consist of an intensely enhancing mass and an iso- or hypoattenuating cap on CECT. The inferior turbinate seems to be a common site of origin, and bony changes are not uncommon features of LCHNC. CT is useful not only in identifying the site of origin and assessing the extent but also in suggesting the nature of LCHNC.

Nasal septal lobular capillary haemangioma in West Africa sub-region: a case report

INTRODUCTION

Lobular capillary haemangioma is a rare vascular lesion of the nose. It is the aim of this communication to highlight the importance of considering this lesion as an important differential diagnosis of bleeding lesion in the nasal cavity.

CASE PRESENTATION

A case report of a 41-year-old female who presented with an obstructive, bleeding, pedunculated left nasal mass arising from the nasal septum in the anterior nasal cavity. An initial diagnosis of squamous papilloma was made and she had excision of the mass done under local anaesthesia. Tissue histology revealed lobular capillary haemangioma. The patient has been followed up for over 15 months and is still free of the lesion.

CONCLUSION

To the best of our knowledge, this is the first report in the literature of lobular capillary haemangioma in the nasal septum in West Africa. The case is reported due to the rarity of this lesion in our environment.

Lobular capillary hemangioma of the nasal cavity: A retrospective study on 40 patients

BACKGROUND

Nasal lobular capillary hemangioma (LCH) is a benign lesion of unknown etiology that must be included in the differential diagnosis of vascular lesions. Based on a large cohort of LCH patients, we retrospectively analyzed the clinical presentation, histological and radiological findings, and the treatment strategy.

METHODS

Clinical records of 40 patients affected by LCH, treated in a 20-year period at two university hospitals, were reviewed. Data concerning symptoms, possible etiologic factors, endoscopic findings, imaging studies, and treatment were collected.

RESULTS

Previous nasal trauma and pregnancy were identified as possible causes in six (15%) and two (5%) patients, respectively. The main symptoms were unilateral epistaxis (95%) and nasal obstruction (35%). Lesions ranged in size from 1 to 8 cm and mainly involved the nasal septum (45%) and the nasal vestibule (17.5%). In the four (10%) patients with a large lesion, radiological evaluation was helpful not only in assessing the extent, but also in suggesting the possible nature of the lesion. All patients underwent endoscopic resection under local (72.5%) or general (27.5%) anesthesia. At mean follow-up time of 53 months, no recurrence has been observed.

CONCLUSION

To the best of our knowledge, this is the largest series of patients with nasal LCH. When the mass is considerable in size, differentiation from other hypervascularized lesions may be intriguing. Under these circumstances, information obtained with imaging may sometimes suggest a correct diagnosis without resorting to biopsy. Endoscopic surgery is the treatment of choice even for large lesions, that do not require preoperative embolization.

Recurrent inverted papilloma of a pediatric patient: clinico-radiological considerations

Inverted papilloma (IP) of the nasal cavity and paranasal sinuses is an uncommon pathology, especially in the pediatric population. We present a pediatric case of recurrent IP in the left nasal cavity. The physical examination of a 9-year-old girl revealed a polypoid mass filling the middle meatus in the left nasal cavity. Purulent secretion and adenoid vegetation obstructing the choanea were also noted. Coronal and axial maxillo-facial computed tomography demonstrated a mass in the nasal cavity, enlarging the left middle meatus. We discussed the imaging findings and treatment of IP and concluded that it should have been included in the differential diagnosis of nasal mass lesions in the pediatric population.

Lobular capillary hemangioma of the nasal cavity in child

Although the head and neck is not an uncommon region, the nasal cavity is extremely rare sites for lobular capillary hemangioma (LCH) in children. The authors report a case of an 11-year-old boy with LCH of the nasal cavity presenting with nasal obstruction and epistaxis. To our knowledge, on searching the English literature, only nine cases of hemangioma of nasal cavities have been reported in children since 1985. The authors feel that it should be considered in the differential diagnosis of lesion of the nasal cavity.
