Recurrent Angiolymphoid Hyperplasia with Eosinophilia of the Parotid

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign vasculoproliferative disorder. It usually affects young adults presenting as papules or nodules involving the skin of head and neck region and rarely involves extracutaneous sites. ALHE involving parotid is rare and can be a diagnostic dilemma as it mimics a parotid neoplasm. This is a case of a 23 year old male presenting with a recurrent swelling over the left parotid region post surgery. Ultrasonography revealed a vascular soft tissue lesion in the preauricular region suggestive of a benign lesion. Contrast enhanced magnetic resonance imaging showed a hyperintense lesion involving the superficial lobe of the left parotid gland. Patient underwent superficial parotidectomy and histopathologically was diagnosed to have ALHE. Very few cases have been reported and this case is highlighted as the facial nerve was enmeshed by the intraparotid lesion which was a surgical challenge.

Angiolymphoid Hyperplasia With Eosinophilia: New Concept to Lower Recurrence

Angiolymphoid Hyperplasia with Eosinophilia (AHLE) is a rare benign vascular disorder of unknown etiology. While World Health Organization recognizes it as a benign neoplasm, its progressive nature and high recurrence rate are consistent with being a locally malignant tumor. It may present as solitary or multiple nodules with more predilection to head and neck region, especially auricular area. Despite variety of available treatment options, high recurrence rate remains a compelling issue. The spectrum of these treatment modalities includes topical or systemic steroids use, intralesional injection of certain materials such as Bleomycin, Vinblastine or interferon, or even surgical excision.In our study, the authors present a case of middle-aged female with recurrent AHLE in left concha and preauricular region. Excision of the lesion with 4 mm of the normal surrounding skin, preserving auricular cartilage, was done while the resultant defect was covered by grafted Temporoparietal Fascia Flap. Our 1-year follow-up period showed aesthetically accepted outcome with no recurrence.The authors hypothesize that treating AHLE as a locally malignant tumor by excising the lesion with 4 mm safety margin decreases recurrence rates. Moreover, reconstruction by grafted temporoparietal fascia flap achieves a reasonable aesthetic outcome with minimal donor site morbidity.

Angiolymphoid hyperplasia with eosinophilia in a hand treated with a reverse digital island flap and artificial skin: a case report

BACKGROUND

Angiolymphoid hyperplasia with eosinophilia is a rare nodular skin tumor characterized by eosinophilic invasion and vascular proliferation. Previous reports suggested that irritation and inflammation are the causative factors of this disease. Most cases of angiolymphoid hyperplasia with eosinophilia occur around the auricle, forehead, and scalp; the hand is rarely affected. Moreover, the tumor seldom presents as multiple nodules.

CASE PRESENTATION

A 67-year-old Japanese woman presented with a complaint of skin masses on her left thumb and index finger, which had gradually grown in size over the past few months. A biopsy was performed confirming a diagnosis of angiolymphoid hyperplasia with eosinophilia. The aponeurosis on her index finger was resected and tissue was reconstructed using a reverse palmar digital island flap harvested from the base of her index finger. The thumb lesion was also resected and covered with collagen-based artificial skin. Gradual progression of skin epithelialization followed by healing was noted 2 months after the surgery.

CONCLUSION

Angiolymphoid hyperplasia with eosinophilia is a rare tumor; it is seldom seen in the hands. It is generally treated by surgical resection. It is important to resect a sufficiently large area of the tissue due to the possibility of relapse in some cases. Furthermore, appropriate reconstruction is mandatory after wide margin tumor resection.

Combined pulsed dye and CO2 lasers in the treatment of angiolymphoid hyperplasia with eosinophilia

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon dermatosis of unknown etiology that manifests as characteristic red nodules and papules with a predilection for the scalp and periauricular region. Treatment is required for both esthetic and functional reasons, as lesions may ulcerate and bleed. Many treatment approaches have been reported, including excision, systemic medical approaches, topical or intralesional therapies, and non-invasive modalities including cryotherapy, electrosurgery, and laser. Treatments have exhibited variable efficacy, and the recurrence rate is 100 %. We report the combination of pulsed dye laser and CO2 laser in the treatment of ALHE in 14 patients. All patients exhibited clinical response after a mean of 2.4 ± 0.4 treatment sessions. The clinical efficacy of the combined treatment, together with its well-tolerated nature, render the use of pulsed dye laser in combination with CO2 laser, a viable treatment for debulking ALHE lesions. Ongoing maintenance treatments are needed to due to the high degree of relapse.

Epidemiology and treatment of angiolymphoid hyperplasia with eosinophilia (ALHE): A systematic review

BACKGROUND

Current knowledge of angiolymphoid hyperplasia with eosinophilia (ALHE) derives from retrospective reports and case series, leading to a nonevidence-based treatment approach.

OBJECTIVE

We sought to systematically review the literature relating to cutaneous ALHE to estimate its epidemiology and treatment outcomes.

METHODS

A literature search of PubMed, EMBASE, Web of Science, and Google Scholar was conducted. Articles detailing cases of histologically confirmed cutaneous ALHE were included.

RESULTS

In all, 416 studies were included in the review, representing 908 patients. There was no sex predominance among patients with ALHE. Mean age at presentation was 37.6 years. There was a significant association between presence of multiple lesions and pruritus, along with bleeding. Surgical excision was the most commonly reported treatment for ALHE. Treatment failure was lowest for excision and pulsed dye laser. Mean disease-free survival after excision was 4.2 years. There were higher rates of recurrence postexcision with earlier age of onset, longer duration of disease, multiple lesions, bilateral lesions, pruritus, pain, and bleeding.

LIMITATIONS

Potential for publication bias is a limitation.

CONCLUSIONS

Surgical excision appears to be the most effective treatment for ALHE, albeit suboptimal. Pulsed dye and other lasers may be effective treatment options. More studies are needed to improve the treatment of ALHE.

Angiolymphoid hyperplasia with eosinophilia: Successful treatment with the Nd:YAG laser

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon idiopathic proliferation of blood vessels that manifests in adults as isolated or grouped papules, plaques, or nodules in the skin of the head and neck. We describe the case of a 31-year-old woman with a 3-year history of persistent ALHE, located on the tragus of her right ear, with no sign of spontaneous regression over a period of 3-6 months and refractory to intralesional corticosteroids. We report the successful use of the Nd:YAG laser for this condition, which offered excellent symptomatic and cosmetic results and suggests the consideration of this modality in the treatment of ALHE.

Treatment of angiolymphoid hyperplasia with eosinophilia with the carbon dioxide laser

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon, idiopathic condition that presents with isolated or grouped plaques or nodules in the periauricular region, forehead, or scalp. ALHE is marked by a proliferation of blood vessels with distinctive large endothelial cells accompanied by a characteristic inflammatory infiltrate that includes eosinophils. The lesion is benign but may be persistent and difficult to eradicate. Various therapeutic modalities that have been tried for its treatment include intralesional and oral corticosteroids, cryotherapy, oral retinoids, vinblastine, surgical excision, laser therapy, and INFalpha2a. We report two cases with this rare condition: one patient, treated with cryotherapy, did not improve, while the second patient was successfully treated with the CO(2) laser.

Angiolymphoid Hyperplasia Successfully Treated with an Ultralong Pulsed Dye Laser

BACKGROUND

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign vascular proliferation characterized by dermal or subcutaneous nodules or both, primarily in the head and neck. We report the successful treatment of ALHE without scarring using a 595 nm ultralong pulsed dye laser, which applies a unique combination of longer wavelengths, a longer pulse duration, and a higher fluence.

OBJECTIVE

To report the use of the 595 nm pulsed dye laser in the treatment of ALHE and to detail the particular aspects of this laser that make it uniquely qualified to treat this entity.

METHODS

Case report and review of the literature.

RESULTS AND CONCLUSION

This laser may be used as an effective treatment for ALHE and has advantages over alternative treatments and older lasers. Specifically, the longer wavelength (595 nm) penetrates more deeply into dermal tissue, which produces more uniform coagulation across the entire vessel.

Mohs Micrographic Surgery for Angiolymphoid Hyperplasia with Eosinophilia

BACKGROUND

Angiolymphoid hyperplasia with eosinophilia is a benign vascular proliferation that typically presents on the head and neck. Multiple treatment modalities have been proposed for angiolymphoid hyperplasia with eosinophilia, each with limited success or undesirable side effects. At this time, standard surgical excision is considered the treatment of choice but carries recurrence rates of 33% to 50%.

OBJECTIVE

The objective was to present a case of angiolymphoid hyperplasia with eosinophilia successfully extirpated using Mohs micrographic surgery.

METHODS

A 52-year-old woman presented with an ill-defined solitary plaque of angiolymphoid hyperplasia with eosinophilia within her left conchal bowl that enlarged despite conservative therapy with intralesional and topical corticosteroids. Mohs micrographic surgery using the fresh tissue technique and standard hematoxylin and eosin staining was performed. The characteristic histologic features of angiolymphoid hyperplasia with eosinophilia were readily identifiable on frozen sections and complete extirpation required two stages of micrographically controlled resection.

RESULTS

Resection of angiolymphoid hyperplasia with eosinophilia of the conchal bowl with complete resolution of symptoms and no evidence of clinical recurrence 8 months after surgery.

CONCLUSION

Given the high recurrence rates reported for standard excision, Mohs micrographic surgery with complete margin examination should be considered as a treatment option for angiolymphoid hyperplasia with eosinophilia, particularly for lesions with ill-defined margins or in locations where tissue sparing is desirable.

Epithelioid hemangioma of the orbit

OBJECTIVE

To describe the histopathologic features of two cases of epithelioid hemangioma occurring in the orbit and to distinguish this condition from Kimura's disease and from other vascular lesions of proliferated endothelium.

DESIGN

Two interventional case reports.

INTERVENTION

Treatment consisted of orbitotomy with excision of the tumor.

MAIN OUTCOME MEASURES

Histopathologic examination including light microscopy, immunohistochemistry, and electron microscopy and clinical follow-up.

RESULTS

In one case, there was no local recurrence after 2 years of follow-up. In the other case, local recurrence required re-excision 2 years after surgery with no apparent recurrence 16 years later. Histopathologic examination of both tumors disclosed an epithelioid hemangioma. A characteristic finding was the presence of peculiar plump vacuolated endothelial cells lining the vascular lumina.

CONCLUSIONS

Epithelioid hemangioma is an uncommon benign vascular tumor that can occur in the orbit, and surgical excision is usually required. It is the same condition as angiolymphoid hyperplasia with eosinophilia. There are distinct clinical and histopathologic characteristics to distinguish epithelioid hemangioma from Kimura's disease and from other vascular tumors.

Angiolymphoid hyperplasia with eosinophilia successfully treated with a long-pulsed tunable dye laser

BACKGROUND

To date, both surgical excision and laser treatments for angiolymphoid hyperplasia with eosinophilia (ALHE) have resulted in scarring.

OBJECTIVE

Based on the principle of selective photothermolysis, we considered employing the newer long-pulsed tunable dye laser in the treatment of ALHE, as less scarring would be expected and deeper blood vessels could be ablated.

METHODS

After punch biopsy specimens confirmed the diagnosis, the patient was treated on two separate occasions, 2 months apart with a long-pulsed tunable dye laser.

RESULTS

The lesions flattened after the initial treatment and resolved after a second treatment. No scarring was detectable and no recurrence was noted in follow-up after 1 year.

CONCLUSION

We conclude that the long-pulsed tunable dye laser can be employed successfully to treat superficial lesions of ALHE, particularly in cosmetically sensitive areas.

Cutaneous vascular proliferation. Part II. Hyperplasias and benign neoplasms

This second part of our review about vascular proliferations summarizes the clinicopathologic features of the cutaneous vascular hyperplasias and benign neoplasms. Hyperplasias comprise a heterogeneous group of vascular proliferations that eventually show a tendency to regression. Angiolymphoid hyperplasia with eosinophilia is included within the group of hyperplasias because of its historical denomination and its reactive nature, probably as a consequence of an arteriovenous shunt, although usually the lesions do not regress. Pyogenic granuloma, bacillary angiomatosis, intravascular papillary endothelial hyperplasia, and pseudo-Kaposi's sarcoma qualify as vascular hyperplasias because they regress when the stimulus that initiated them is removed. Benign neoplasms form a large group of hemangiomas with distinctive clinicopathologic characteristics, although some of them are of recent description and may produce diagnostic difficulties. We classified cutaneous benign vascular neoplasms according to their cell lineage of differentiation, for example, endothelial, glomus cell, and pericytic differentiation. Subsequent categories are established according to the size of the involved vessels (capillaries, venules and arterioles, or veins and arteries) or the nature of the proliferating vessels (blood or lymphatic vessels). Capillary and cavernous hemangiomas have been the terms classically used to name the most common variants of benign vascular neoplasms (i.e., infantile hemangiomas), but they are not the most appropriate denominations for these lesions. First, these names are not contrasting terms. Furthermore, most of the socalled "cavernous" hemangiomas are not hemangiomas (neoplasms) at all, but venous malformations. The most important conceptual issue is that, at any point in time, a particular hemangioma has its own histopathologic pattern throughout the depth of the lesion. For these reasons, we classified hemangiomas into superficial and deep categories. Some of the lesions reviewed have been recently described in the literature, and they may histopathologically mimic lesions of Kaposi's sarcoma; these include targetoid hemosiderotic hemangioma, microvenular hemangioma, tufted hemangioma, glomeruloid hemangioma, kaposiform hemangioendothelioma, spindle-cell hemangioendothelioma, and benign lymphangioendothelioma. In each of these lesions, we update and emphasize those clinical and histopathologic features that are helpful for differential diagnosis with lesions of authentic Kaposi's sarcoma in any of its three stages of development (patch, plaque, or nodule).

Carbon Dioxide laser in the treatment of cutaneous disorders

Experienced gained with the Carbon Dioxide Laser over a two year period is documented. This laser modality has been used successfully for many indications. We believe it is the treatment of choice for conditions such as resistant verrucae, extensive actinic cheilitis or labial leukoplakia, and for the cosmetic removal of widespread facial tumours, some keloid scars and rhinophyma.

Angiolymphoid hyperplasia with eosinophilia of the hand. A case report

Angiolymphoid hyperplasia with eosinophilia is an uncommon benign vascular neoplasm manifested by multiple or solitary subcutaneous nodules, usually on or about the head of young adults. Angiolymphoid hyperplasia with eosinophilia is characterized microscopically by marked proliferation of large endothelial cells with a mixed inflammatory infiltrate consisting of lymphocytes, histiocytes, and eosinophils. This benign skin disorder may resemble an angiosarcoma both clinically and histologically. We wish to report a patient with angiolymphoid hyperplasia with eosinophilia on the palm of the hand and discuss therapeutic recommendations.

Angiolymphoid hyperplasia with eosinophilia limited to the vulva

A patient with angiolymphoid hyperplasia with eosinophilia is described. This is, to our knowledge, the first case report in which the lesions were located on the vulva.
