Primary glomangioma of the liver: imaging findings.

Glomus organs are small arteriovenous anastomoses that are chiefly responsible for thermoregulation of the distal portion of the extremities. Glomangiomas are benign tumors of these bodies. Glomangiomas occur preferentially in the fingers and toes, but some case reports have described primary glomangiomas in the respiratory or gastrointestinal tract and the genitals. To date, no glomangiomas of the liver have been observed. We report on a 61-year-old patient in whom routine ultrasound disclosed a subcapsular well-defined mass in the liver. On imaging studies, no correspondence to the usual liver tumors was found. Magnetic resonance-guided biopsy showed a primary glomangioma of the liver. Clinically, the patient had no appetite and lost weight over several months. Due to the patient's weight loss and potential malignant transformation, the tumor was excised. Histologic work-up confirmed the diagnosis of a glomangioma with no signs of malignancy.

Presentation of an unusual benign liver tumor: primary hepatic glomangioma.

Glomus organs are small arteriovenous anastomoses chiefly responsible for thermoregulation of the distal portion of the extremities. Glomangiomas are benign tumors of these bodies. They occur preferentially in the fingers and toes, but some case reports describe primary glomangiomas in the respiratory or gastrointestinal tract and genitals. To date, no glomangiomas of the liver have been reported. We report on a 61-year-old patient in whom routine ultrasound disclosed a subcapsular well-defined mass in the liver. Further imaging showed that the mass did not correspond to any of the usual liver tumors. Biopsy finally revealed it to be a primary glomangioma of the liver. Clinically, there was lack of appetite and weight loss over a period of several months. Owing to the possibility of malignant transformation of glomangiomas, as described in the literature, the tumor was excised under existing clinical symptoms and continued slow growth. Further histological evaluation of the tumor did not reveal malignancy. Primary glomangioma of the liver is a new differential diagnosis for benign liver neoplasms. Because there is a potential for malignant transformation, the existence of clinical symptoms and continuing growth are indications for resection.

Congenital glomangioma: case report and review of the world literature.

Glomangiomas, or multiple glomus tumors, occur in disseminated, localized, or congenital plaquelike forms. The first two cases of congenital plaquelike glomangioma were described in 1990. We report a 9-year-old girl with a congenital, violaceous, 75-cm2 indurated plaque of the left abdomen that showed the classic histologic findings of glomangioma. In our review of the world literature, we found 11 additional, well-documented cases of glomangioma present at birth. Ten of these patients had violaceous indurated plaques, and the other two had clusters of discrete nodules. The majority of lesions were painless and enlarged with body growth. Many patients developed satellite lesions at sites distant from the original glomangiomas later in life. Family history of glomangioma was positive in 4 of the 12 patients.

Multiple familial cutaneous glomangioma: a pedigree of 4 generations and critical analysis of histologic and genetic differences of glomus tumors.

BACKGROUND: Glomangiomas are benign tumors arising from neuromyoarterial cells surrounding cutaneous arteriovenous anastomoses that serve as temperature regulators. They exist as solitary or multiple types, occurring sporadically or in a familial pattern, the latter of which is rare. OBJECTIVE: We describe a 4-generation pedigree of familial cutaneous glomangioma, in addition to the 3 other well-documented pedigrees reported in the literature to date, and we clarify ways in which to distinguish the different types of glomus tumors. METHODS: Nodular skin lesions of 4 affected family members were analyzed by histologic, immunohistologic, and electron microscopic methods. To elucidate the gene defect in this family, we searched for a linkage to a candidate locus on chromosome 11q23 previously identified in paragangliomas, one form of glomus tumor, in 16 family members of 4 generations by using polymorphic markers. RESULTS: The diagnosis of disseminated cutaneous glomangiomas was confirmed histologically in 4 family members of 3 different generations. Glomangiomas were transmitted in an autosomal dominant pattern via the paternal line. Genetic linkage analysis of the affected family members excluded linkage to chromosome 11q23. CONCLUSION: An autosomal dominant pattern of inheritance has been described for glomus tumors of the paraganglioma type originating from the APUD cell system, the underlying genetic defect of which has been mapped to chromosome 11q23. In contrast, we show that the genetic defect in disseminated cutaneous glomus tumors of the glomangioma type deriving from smooth muscle cells or pericytes is not linked to chromosome 11. Thus we suggest that the common term glomus tumor, used for both paragangliomas and glomangiomas in the current literature, is misleading and should be avoided because these tumors have different histologic derivation and genetic origin.

[Primary glomangioma of the liver. A new differential benign liver tumor diagnosis].

Glomus organs are arteriovenous anastomoses which control the thermoregulation of the extremities. Benign tumors of these glomus organs, termed "glomangiomas", are therefore most frequently located in the fingers and toes. Case reports of primary glomangiomas in the respiratory- and gastrointestinal tracts as well as in the genital organs have been published. On the other hand, glomus tumors of the liver have not yet been described. We report the case of a 61-year-old patient with a smooth subcapsular lesion within the liver detected by a routine ultrasound scan. Further diagnostic imaging did not match with one of the common liver tumors. The diagnosis of a glomangioma was finally made by liver biopsy and subsequent histology. A review of the literature revealed a potential transformation of glomangiomas. Since the patient reported on inappetence weight loss and the tumor showed growth tendency, the indication for surgical excision was made. Final histologic investigation revealed no signs of malignancy. The primary glomangioma of the liver is a new differential diagnosis of benign liver tumors. As there is a possibility of malignant degeneration, we propose the decision for surgical removal once there are clinical symptoms and a growth tendency of the lesion.

Two cases of segmental multiple glomangiomas in a family: type 1 or type 2 segmental manifestation?

Several autosomal dominant skin diseases may manifest cutaneous mosaicism. Two types of segmental arrangement can be distinguished: type 1 is characterized by segmental lesions with similar severity to that observed in the diffuse phenotype, the remaining skin being normal; type 2 is characterized by segmental lesions showing a major degree of severity and milder lesions diffusely arranged. Multiple glomus tumours have recently been included in the group of genodermatoses showing type 2 segmental involvement. A family with 2 cases of multiple glomangiomas arranged in a segmental fashion is reported. A 12-year-old girl presented multiple nodular glomangiomas on her right buttock and thigh, in a band-like distribution. A sister of her paternal grandfather showed plaque-like multiple glomangiomas on her left thigh and various glomangiomas on her right buttock and arm. No other family members were known to be affected. Two new cases of familial segmental multiple glomangiomas are reported, with the particularity that one of these exhibited type 2 segmental manifestation and the other type 1 from a clinical point of view.

Multiple hereditary glomangiomas: successful treatment with sclerotherapy.

Glomangiomas are characterized by cavernous vascular channels surrounded by glomus cells. Multiple glomangiomas, although usually painless, can be a few centimetres in size and appear as blue phlebectatic lesions. Surgical excision of multiple glomangiomas can lead to scarring and recurrences. Laser treatment using vascular lasers and CO2 lasers has been useful in small, superficial lesions. We present the successful sclerotherapy treatment of multiple glomangiomas using sodium tetradecyl sulphate in a 59-year-old man who presented with postoperative recurrence of multiple lesions.

Facial "glomangiomas": large facial venous malformations with glomus cells.

BACKGROUND: "Glomangiomas" are benign cutaneous vascular lesions consisting of convoluted, abnormally formed venous channels lined by cuboidal and oval epithelioid, alpha-actin-positive, glomus cells. Three different clinical variants of glomangioma have been recognized: solitary, multiple, and nodular, or plaquelike. Inheritable forms are common. OBJECTIVE: We describe in 7 patients (2 of them having a familial glomangiomatosis) the rare facial location of glomangiomas to differentiate this type from common facial venous malformation (VM). METHODS: We analyzed clinical data (photographs), course, investigations (computed tomographic scans in 4 patients, magnetic resonance imaging in 6, arteriography in 2, direct puncture phlebography in 4, and pathologic examinations in all 7), and outcome with treatment. RESULTS: Lesions were soft, composed of multiple nodules, confluent and plaquelike, deep blue or blue-to-purple, sometimes sagging, one-sided in a cheek, extending to the lips in 5 patients, to the chin in 4, and to the lower eyelid in 4. They were poorly compressible, a finding different from common facial VMs. In a young man extensive back involvement was associated. Among radiologic investigations, only magnetic resonance imaging after gadolinium enhancement offered some differential features with common VMs. However, histopathologic examination clarified the differential diagnosis: although the large tortuous venous channels were reminiscent of capillary-venous malformation, in many vessels the walls contained one or several rows of glomus cells. CONCLUSION: Multiple plaquelike facial "glomangiomas" mimic a common venous malformation because of their blue hue. However, with experience, one can clinically recognize them, and their pathologic aspect is distinctive. Management should differ slightly from that for common facial VM because sclerotherapy has proven to be less effective. Therefore surgical treatment is the only helpful therapeutic option.

Additional glomangioma families link to chromosome 1p: no evidence for genetic heterogeneity.

Venous malformations are a common abnormality of the vasculature that may occur sporadically or, more rarely, as an autosomal dominant trait. One familial form of venous malformations has previously been linked to chromosome 9p. Mutations in the gene encoding Tie2, an endothelial specific receptor tyrosine kinase, have been identified in four different families. Glomangiomas are a subtype of venous malformations with glomus cell involvement. These cutaneous lesions can be inherited as an autosomal dominant disease with reduced penetrance and variable expressivity. We present evidence of linkage to chromosome 1p21-1p22 using four new glomangioma families, with a combined maximum two-point lod score of 7.32 at marker D1S2804. Markers D1S2129 and D1S2881 define the 24-cM linkage interval determined by recombination within affected individuals. A recent report also showed linkage of the glomangioma locus to chromosome 1p. A total of 9 families now map to this region, suggesting a decreased likelihood of locus heterogenity in familial glomangiomas. Investigation of candidate genes within the interval should provide new insights into lesion formation in inherited venous malformations.

Treatment of multiple glomangioma with tuneable dye laser.

BACKGROUND: Multiple glomangiomas are a rare clinical occurrence. In the past, various treatments have been proposed for eradication of these tumours. OBJECTIVE: An alternative and effective therapy for multiple glomangioma is proposed. RESULTS: The effective clinical response of multiple, painful, bluish-black lesions on the soles of the feet and the hands, diagnosed as multiple glomangioma, to flashlamp tuneable dye laser is reported. CONCLUSION: The flashlamp tuneable dye laser is an effective modality in the treatment of multiple glomangioma.

Orbital-conjunctival glomangiomas involving two ocular rectus muscles.

PURPOSE: To report two glomangiomas in one orbit, each isolated to a rectus muscle. DESIGN: Clinicopathologic correlation. METHODS: A 12-year-old boy developed two separate vascular tumors, near the insertions of the medial rectus and superior rectus muscles, respectively. A biopsy of one tumor was studied by light microscopy and immunohistochemistry. RESULTS: Histopathology revealed blood vessels surrounded by cuboidal cells characteristic of glomangioma. The cells showed immunoreactivity for smooth muscle actin and vimentin, supporting the diagnosis. CONCLUSIONS: Glomangioma can involve the rectus muscles in the conjunctiva and orbit, and should be considered in differential diagnosis of vascular tumors in the ocular region.

Local and systemic expression of basic fibroblast growth factor in a patient with familial glomangioma.

Glomangiomas are rare cutaneous tumours composed of glomus cells, which are modified smooth muscle cells. The aetiology of this condition is thought to involve a mutation in a novel gene acting to regulate angiogenesis. We report a patient from a large family with three generations affected by familial multiple glomangiomas. We hypothesized that the growth factors basic fibroblast growth factor and vascular endothelial growth factor, which stimulate/regulate angiogenesis could be involved in the pathogenesis of these lesions. Therefore, using enzyme-linked immunosorbent assays and immunohistochemistry, respectively, we measured systemic and tissue levels of these growth factors in a patient with familial glomangiomas. In addition, we investigated endothelial mitogenicity of the patient's serum as a functional assay of systemic growth factor activity.

Hereditary multiple glomangiomas.

Hereditary multiple glomangiomas are an interesting rare problem which can either present as multiple painful cutaneous lesions or, rarely, a cosmetic challenge due to site, size or number of lesions. It may also pose a diagnostic dilemma, which can only be settled by biopsy. Malignant change in glomangioma is extremely rare and only a few cases are well documented in literature. A case report of this condition, along with extensive review of the literature, is presented. The prognosis of various forms of glomangiomas and efficacy of diagnostic and therapeutic tools is discussed.

The glomangioma in the differential diagnosis of vascular malformations.

Glomus tumors develop from a thermoregulatory unit called the glomus body which is found in high density within the digits of both the hands and feet. To note, even though less frequently, these tumors can present in extradigital locations. Usually it presents as a small, 1-cm bluish nodule. Glomangioma (multiple glomus tumors) is to be differentiated clinically from the more solitary glomus tumor on the basis of larger size and prominent vascular markings. Although glomangioma is described in literature, the major textbooks of plastic surgery fail to mention it. A report of an unusual case of a large glomangioma in the shoulder of a 13-year-old female is presented. Clinical picture, investigation, surgical treatment, and pathology of this lesion are discussed.

Glomangioma in the prepuce of a dog.

A case of preputial glomangioma in an 8-year-old Springer Spaniel dog is reported. The dog presented a solitary nodular mass, approximately 3.5 x 5.2 cm in diameter, located on the lateral wall of the prepuce at the base of the penis. Histologically, the excised tumour mass consisted of proliferating round epithelioid cells arranged in a cordon-like structure around small blood vessels. The neoplastic cells were positive for alpha smooth muscle actin and negative for cytokeratin, desmin, S-100 protein and neurone-specific enolase. Based on these pathologic features, the tumour was diagnosed as glomangioma, a neoplasm extremely rare in dogs. To our knowledge, this is the first report of preputial glomangioma in the dog.

Glomangioma of the nasal cavity and paranasal sinuses.

The glomangioma, a benign vascular tumour, derived from the cutaneous glomus bodies, should not be confused with paragangliomas, which are occasionally also referred to as glomus tumours. Up to now, only eleven cases of a glomangioma of the nasal cavity and the paranasal sinuses have been published. We report the case of a patient with a glomangioma of the ethmoidal aircell system. The tumour was completely removed under endoscopic-microscopic vision via endonasal access. A tumour recurrence was not observed over a period of eighteen months. The clinical signs, diagnosis, therapy and histological features will be discussed with reference to the literature.

Intranasal glomangioma.

Glomangioma is a benign tumour of the glomus body. It is a relatively rare tumour in the head and neck region and even rarer in the nasal cavity. We present the 13th documented case of an intranasal glomangioma. A 56-year-old woman presented with a lesion on the nasal septum associated with intermittent nasal pain and epistaxis. Local surgical excision was not only diagnostic but therapeutic as it effected a cure. Intranasal glomangioma has no well-defined presenting features but must be borne in mind as a possible rare cause of nasal pain and epistaxis. We also briefly review the clinical presentation, histology and management of such a rare tumour.

[Multiple familial glomangioma].

Multiple familial glomangiomas are rare vascular tumours, which are inherited as an autosomal dominant trait. They usually arise at puberty or later, and may involve all parts of the skin. In contrast to solitary glomangiomas, they are not painful. Histopathologically, they are characterized by widely dilated vascular spaces, surrounded by only a few glomus cells. In a report on two patients, the clinical, histopathological and immunocytochemical features and the differential diagnosis of multiple familial glomangiomas are discussed.
