Non-lymphoid mesenchymal neoplasms of salivary gland origin are rare, accounting for 1.4% of major sal-ivary gland tumors. Of this group 30% were hemangiomas. Hemangiomas are the most common benign tumors in children, but are rare in old ages. 90% of hemangiomas arise in the first three decades of life. Hemangiomas are classified as capillary(including juvenile type), cavernous, or mixed in type. Salivary gland hemangioma is more common in the parotid(90%) and extremely rare in submandibular gland. We present two adult pa-tients, 69 and 60 years of age, who were referred for palpable mass in the parotid area and submandibular area, respectively. After surgical removal of the lesion, histopathologic examination showed characteristic feature of cavernous hemangioma. The rarity of such a lesion in these locations in old ages have prompted this case report.

Primary Cavernous Hemangioma of the Thyroid Gland

김신우,이경율,진영주,유윤종 대한갑상선학회 2023 International Journal of Thyroidology Vol.16 No.2

Hemangiomas are benign vascular tumors that result from the abnormal proliferation of vascular tissue. Thyroid hemangiomas can develop as a result of procedures such as fine needle aspiration or other secondary trauma. Primary thyroid cavernous hemangioma is an extremely rare condition, with only a few reported cases. In this report, we present the case of an 83-year-old woman who complained of progressively worsening symptoms of right neck obstruction. She was undergoing levothyroxine treatment for hypothyroidism, and there was no specific family history of thyroid issues. The patient presented with a goiter and obstructive symptoms, and denied any history of trauma or invasive procedures. Thyroid sonography revealed a 6.21 cm heterogeneous dominant solid nodule in the right lobe. Additionally, a large mixed cystic and 6 cm solid mass was identified in the right lobe on CT scan. Due to the significant size of the mass and the presence of obstructive symptoms, the patient underwent a right thyroid lobectomy without further evaluations. Histologic examination of the specimen revealed a cavernous thyroid hemangioma. This case report presents our experience in diagnosing cavernous thyroid hemangioma.

MRI Features of Atypical Cavernous Hemangioma Showing Central Filling Defect: A Case Report

김명현,유인규 대한영상의학회 2018 대한영상의학회지 Vol.78 No.4

Cavernous hemangioma is a benign tumor composed of vascular structures and connective tissue. Typical imaging findings of cavernous sinus cavernous hemangioma are a well-defined contour-bulging mass, with homogeneous high signal intensity on T2-weighted images (T2WI), marked homogeneous enhancement of the cavernous sinus, and some sellar extension on magnetic resonance images. However, we experienced an unusual case of cavernous hemangioma, with central filling defects on delayed contrast-enhanced T1-weighted images and central, dark signal intensities on T2WI, which made the diagnosis difficult. The central portion of the lesion was pathologically consistent with central thrombosis. We present the clinical and imaging findings of this unusual case of cavernous hemangioma.

난소 해면상혈관종

박충학(Choong Hak Park) 대한산부인과학회 2000 Obstetrics & Gynecology Science Vol.43 No.7

Hemangioma of the ovary is very rare benign tumor and it is surprising that only about 40 examples have been reported. It is so rare that there is no report in Korean Journal of Obstetrics and Gynecology. There are both benign and malignant lesions of various histologic types in pure mesenchymal tumors of the ovary. Hemangioma of the ovary is benign tumor of vascular origin in this pure mesenchymal tumors of the ovary. Hemangioma of the ovary is considered either a hamartomatous malformation or a true neoplasm and may be associated with hemangiomas in other parts of the genital tract and with hemangiomatosis. Nearly all ovarian hemangiomas show histologically a cavernous or a mixed cavernous-capillary pattern with large vascular spaces. The hemangiomas are usually unilateral and asymptomatic but associated findings may include abdominal swelling and awareness due to the large mass, acute abdominal pain from torsion, ascites, and thrombocytopenia. I have experienced a very rare case of cavernous hemangioma with calcification in the right ovary, combined with mature cystic teratoma in the left ovary in a 22-year-old woman and report it with brief review of literatures.

Multiple Cavernous Hemangiomas of Glans Penis, Penis, and Scrotum

이준민,왕준호,김홍섭 대한비뇨의학회 2008 Investigative and Clinical Urology Vol.49 No.1

Although a hemangioma is usually found in childhood, a cavernous hemangioma of the genitalia is rarely found. Urologists often face difficulty when making the decision for surgery to treat a genital cavernous hemangioma. We report here on a case of a cavernous hemangioma that extended into the glans penis, penile shaft and scrotum. Immediately after surgical excision of the hemangiomas in the penile shaft and scrotum, the worm-like lesions subsided. The protruding lesions of the glans penis were naturally relieved after 12 months follow up. (Korean J Urol 2008;49:92- 94)

Epidural Cavernous Hemangioma with Foraminal Extension

하진경,배채완,강신광,임승철 대한척추신경외과학회 2011 Neurospine Vol.8 No.3

The increased use of magnetic resonance imaging (MRI) has increased the frequency of diagnosis of cavernous hemangioma, but its presentation of an epidural lesion with foraminal extension without intramedullary involvement is very rare. We describe a 31-year-old woman admitted to our department with pain in the left side of her neck and shoulder. Gadolinium enhanced cervical MRI revealed a brightly enhanced, extradural mass (1×1×2 cm sized) with widened neural foramen; after surgical excision, it was histologically confirmed as a cavernous hemangioma. Postoperatively, the patient has no neurological deficit or specific complication. Although this lesion mimicked an epidural- neurogenic tumor, its enhancement pattern indicated a cavernous hemangioma. Accurate preoperative diagnosis is necessary for treatment planning. Cavernous hemangioma must be included in the differential diagnosis of a brightly enhanced, extradural tumors.

요추 신경근병증으로 발현된 순수한 경막외 해면상 혈관종 −증례 보고−

고은실,서한길,이자호,백남종 대한재활의학회 2010 Annals of Rehabilitation Medicine Vol.34 No.2

Pure epidural cavernous hemangiomas of the spinal canal are extremely rare. We describe a case of lumbar epidural hemangioma suspected as a lumbar radiculopathy in a 78-year-old man who presented with a 1-month history of the low back pain and right lower extremity pain. An electrodiagnostic study demonstrated right L4 radiculopathy. Noncontrast magnetic resonance image (MRI) showed a nodular lesion suggestive of a sequestered disc with compression of right L4 root, most likely. Contrast MRI revealed an oval enhancing nodular lesion, 1.4×0.5 cm in size, indicative of a hemangioma in right anterior epidural space at L4 level. He underwent an excisional biopsy. The pathological diagnosis was cavernous hemangioma. His symptoms resolved after the operation. Spinal epidural cavernous hemangioma should be considered as a cause of a lumbar radiculopathy.

Thoracic Extraosseous Epidural Cavernous Hemangioma

Yaldiz, Can,Asil, Kiyasettin,Ceylan, Davut,Erdem, Sahin The Korean Neurosurgical Society 2015 Journal of Korean neurosurgical society Vol.57 No.1

Cavernous hemangiomas were first reported in 1929 by Globus and Doshay, and are defined as benign vascular structures developed between the neural tissues occurring in the central nervous system, consisting of a dilated vascular bed. Cavernous hemangiomas comprise nearly 5-12% of all spinal vascular malformations; however, existence in the epidural space without bone involvement is rare. Only 4% of all cavernous hemangiomas (0.22/1.000.000) are purely epidural cavernous hemangiomas. In this case report, we removed a hemorrhagic thoracic mass presenting with progressive neurological deficits in a 55-year-old male patient. We found this case to be appropriate for presentation due to the rare occurrence of this type of cavernous hemangioma.

Pure Spinal Epidural Cavernous Hemangioma with Intralesional Hemorrhage: A Rare Cause of Thoracic Myelopathy

장동환,김충효,이승진,류영준,김지하 대한척추신경외과학회 2014 Neurospine Vol.11 No.2

Although cavernous hemangiomas occur frequently in the intracranial structures, they are rare in the spine. Most of spinal hemangiomas are vertebral origin and “pure” epidural hemangiomas not originating from the vertebral bone are very rare. Our spinal hemangioma case is extremely rare because of its “pure” epidural involvement and intralesional hemorrhage. A 64-year-old man presented with progressive paraparesis from two months ago. His motor weakness was rated as grade4/5 in bilateral lower extremities. He also complained of decreased sensation below the T4 sensory dermatome, whichcontinuously progressed to the higher dermatome level. Magnetic resonance imaging demonstrated thoracic spinal tumorat T3-T4 level. The tumor was located epidural space compressing thoracic spinal cord ventrally. The tumor was not involved with the thoracic vertebral bone. We performed T3-5 laminectomy and removed the tumor completely. The tumor was not infiltrating into intradural space or vertebral bone. The histopathologic study confirmed the epidural tumor as cavernous hemangioma. Postoperatively, his weakness improved gradually. Four months later, his paraparesis recovered completely. Here, we present a case of pure spinal epidural cavernous hemangioma, which has intralesional hemorrhage. We believe cavernous hemangioma should be included in the differential diagnosis of the spinal epidural tumors.

A cavernous hemangioma located in the axillary area: Challenges in preoperative diagnosis and operation

Jihye Choi,Chan Sub Park,Joonseog Kong,Hyun-Ah Kim,Woo Chul Noh,Min-Ki Seong 대한종양외과학회 2019 Korean Journal of Clinical Oncology Vol.15 No.2

Cavernous hemangiomas are benign neoplasms of endothelial cells. Although this neoplasm has the potential to develop in all parts of the body, it rarely develops in the axilla; in fact, there are only two case reports of axillary cavernous hemangiomas in the literature. Here, we describe a third case, which occurred in a 30-year-old Korean woman. The patient presented with a palpable mass in the left axilla that was initially thought to be either a phyllodes tumor or a lymphoma based on imaging studies. However, the results of an excisional biopsy led to a diagnosis of cavernous hemangioma. Although uncommon, a cavernous hemangioma can be encountered unexpectedly, presenting as a mass in axilla. Although usually curative, surgery may be challenging not only because of the rarity of the condition, but also because of inconsistent preoperative findings and the involvement of large vessels
