Angiolymphoid hyperplasia with eosinophilia of the external ear canal

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.

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.

Outcomes of Kimura’s disease after radiotherapy or nonradiotherapeutic treatment modalities

PURPOSE

To evaluate the clinical outcome of Kimura's disease and to identify the optimal treatment regimen for Kimura's disease.

METHODS AND MATERIALS

Between 1984 and 2003, 14 patients with Kimura's disease were treated with radiotherapy (RT) and 9 patients were treated with local excision or systemic steroids. The radiation doses ranged from 20 to 45 Gy. Immunohistochemical studies were performed in 13 cases.

RESULTS

At RT completion, a marked response in terms of tumor size was noted in most cases. The median follow-up was 65 months. Local control was obtained in 9 (64.3%) of the 14 in the RT group and in 2 (22.2%) of the 9 in the non-RT group. No secondary malignancies were observed in the RT group.

CONCLUSION

These results supports the finding that RT is more effective against Kimura's disease. Simple or immunohistochemical features did not influence the treatment outcome.

Doença de Kimura não é hiperplasia angiolinfóide com eosinofilia: correlação clinicopatológica com revisão da literatura e definição de critérios diagnósticos

A doença de Kimura é doença inflamatória crônica que se manifesta como crescimento tumoral indolor na região da cabeça e do pescoço, freqüentemente associada à linfoadenopatia cervical. Por ser doença rara, ter sido descrita inicialmente na literatura oriental e ter características em comum com a hiperplasia angiolinfóide com eosinofilia, a doença de Kimura tem sido confundida com essa enfermidade, da qual deve ser distinguida. Neste artigo, revisam-se as características clínicas e histopatológicas e apresentam-se critérios para a diferenciação dessas duas entidades.

Hiperplasia angiolinfóide com eosinofilia: relato de dois casos

Os autores apresentam dois casos de hiperplasia angiolinfóide com eosinofilia, doença relativamente rara. Uma das pacientes apresentava lesões exuberantes e de localização incomum, já que é em geral situada na cabeça e/ou no pescoço. A histopatologia corada com HE e a imuno-histoquímica com fator VIII confirmaram o diagnóstico e a origem endotelial das lesões de ambas as pacientes.

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 proliferations. Part III. Malignant neoplasms, other cutaneous neoplasms with significant vascular component, and disorders erroneously considered as vascular neoplasms

In this third and last part of our review of cutaneous vascular proliferations we include malignant vascular neoplasms and a group of heterogeneous cutaneous neoplasms characterized by a significant vascular component. We also review some disorders that, in our opinion, have been erroneously considered as vascular neoplasms. We review the epidemiologic, histogenetic, clinical, and histopathologic aspects of Kaposi's sarcoma in its four distinctive variants (classic, African-endemic, immunosuppressive drug-associated, and AIDS-associated Kaposi's sarcoma). There is still controversy about whether Kaposi's sarcoma represents a reactive vascular proliferation or a true neoplastic proliferation. In any event, most authors believe that Kaposi's sarcoma does not produce metastatic disease, but rather develops in multifocal fashion. However, Kaposi's sarcoma may cause death, especially in immunosuppressed patients. Epithelioid hemangioendothelioma, Dabska's tumor, and retiform hemangioendothelioma are examples of low-grade angiosarcoma. In contrast, cutaneous angiosarcomas, including the clinical variants of angiosarcoma of face and scalp in elderly patients, angiosarcoma associated with lymphedema, and radiation-induced angiosarcoma are highly aggressive neoplasms with poor prognosis and most patients die within a short period after presentation. A group of benign and relatively frequent cutaneous neoplasms, including multinucleate cell angiohistiocytoma, angiofibroma, angioleiomyoma, angiolipoma, cutaneous angiolipoleiomyoma, and cutaneous angiomyxoma are here covered because of their significant vascular component. Finally, we review briefly a series of cutaneous disorders that have been erroneously considered as vascular neoplasms. Kimura's disease is an inflammatory reactive condition of unknown origin, "benign" angioendotheliomatosis is a reactive intravascular proliferation of endothelial cells that occurs in the skin as a response to a variety of stimuli, "malignant" angioendotheliomatosis is an intravascular lymphoma, and acral pseudolymphomatous angiokeratoma of children (APACHE) is better interpreted as a pseudolymphoma.

Radiation treatment in patients with recurrent Kimura's disease

PURPOSE

To assess the benefits of radiotherapy for patients with recurrent Kimura's disease and to document the role of radiation treatment as a successful mode of therapy.

METHODS AND MATERIALS

From 1985 to 1991, a total of 26 patients with Kimura's disease were treated by local excision and/or systemic steroids at Yonsei University, Yonsei Cancer Center Hospital. Seventeen patients among them eventually had local recurrence after surgical excision. The 17 patients with recurrent Kimura's disease were divided into two groups on the basis of those who received radiation treatment and those who did not. Eight patients in the nonradiation group were treated by systemic steroids alone with individualized doses and schedules. The remaining nine patients in the radiation group were treated by external beam irradiation. The prescribed radiation doses varied from 21.6 to 45 Gy. A comparative analysis on treatment results between both groups was undertaken retrospectively.

RESULTS

The majority of the recurrent cases in the nonradiation group treated by steroids alone experienced rapid rerecurrence of the disease. In contrast, all of the patients except one case in the radiation group achieved excellent local control with moderate doses of radiation. There was a significant difference in the rerecurrence rate between the patients of the radiation group (11%) and the nonradiation group (75%). No clear dose-response relationship could be derived from the patients of the radiation group. No secondary malignancies in the irradiated areas have been observed.

CONCLUSION

Our results suggest that radiation treatment is preferable as an alternative option for patients with recurrent Kimura's disease who have failed to achieve local control by other modalities.

Angiolymphoid hyperplasia with eosinophilia and vascular tumors of the head and neck

PURPOSE

The clinicopathologic distinctions between angiolymphoid hyperplasia with eosinophilia (AHE) and vascular tumors are controversial. Some investigators believe that AHE is a variant of hemangioma, whereas others state that it is an inflammatory phenomenon. To better delineate the clinicopathologic entity of AHE and investigate the efficacy of various treatment regimens, we undertook a retrospective analysis of AHE and compared it with other angiomatous lesions treated at a tertiary referral center.

MATERIALS AND METHODS

We reviewed the histopathologic features of hemangioma, AHE, and angiosarcoma of the head and neck seen in 46 cases at University of California Los Angeles (UCLA) Medical Center between 1950 and 1992. Lesions were evaluated for presence of lymphoid and eosinophilic infiltration, type of endothelial cell, and pattern of vascular proliferation. Patient charts were also reviewed for clinical history and outcome.

RESULTS

The typical findings of AHE were present in 13 cases of conventional hemangioma and angiosarcoma. The clinical data of 8 AHE patients were also reviewed and a benign outcome was observed.

CONCLUSION

We propose that AHE represents an angiomatous neoplasm similar to the hemangioma but characterized by a marked reactive appearance. AHE may comprise part of a spectrum of vascular tumors with differences between lesions depending in part on host-mediated inflammatory and immune responses.

Angiolymphoid hyperplasia with eosinophilia (histiocytoid hemangioma): evaluation of treatment options

Angiolymphoid hyperplasia with eosinophilia is an uncommon benign vascular proliferative lesion of unknown cause. In this report, a case is presented of a patient who was confirmed to be positive for human immunodeficiency virus and in whom the lesion had shown rapid accelerated growth. The case is used to illustrate a variety of therapeutic techniques and to evaluate the effectiveness of the various alternatives in the treatment of this unusual clinical problem. Long-term follow-up after radical excision of the tumor mass is presented.

Angiolymphoid hyperplasia with eosinophilia

Angiolymphoid hyperplasia with eosinophilia is a rare condition and is poorly recognized in the otolaryngological literature. The condition is characterized by the appearance of cutaneous nodules within the head and neck region especially around the external ear. Variable lymphadenopathy and peripheral eosinophilia can occur and the condition can mimic neoplasia. It is important to be aware of this disease entity in order to avoid overtreatment. Surgical removal is the treatment of choice; however, this often multilobulated and poorly delineated lesion often precludes initial wide excision and local recurrence is common. We present three cases of this unusual condition and a brief resumé of the literature.

Epithelioid haemangioma (angiolymphoid hyperplasia with eosinophilia) and Kimura's disease in Chinese

Although Kimura's disease has often been considered to be identical to angiolymphoid hyperplasia with eosinophilia (epithelioid haemangioma), recent studies suggest that they are different clinicopathological entities. In this study, we have made a detailed morphological comparison of 10 cases of epithelioid haemangioma and 40 cases of Kimura's disease occurring in the Chinese population. The epithelioid haemangiomas occurred in the subcutaneous tissue, skin and maxillary antrum, whereas Kimura's disease affected the subcutaneous tissue, major salivary glands and lymph nodes. Distinctive features of epithelioid haemangiomas were exuberant proliferation of vessels lined by cuboidal to hobnail endothelial cells with irregular nuclei and cytoplasmic vacuoles, fibromyxoid matrix, involvement of muscular coat of blood vessels and zonation of inflammatory infiltrate towards the peripheral portion of the lesion. Distinctive features of Kimura's disease were florid lymphoid infiltrate with prominent lymphoid follicles, vascularization of germinal centres, germinal centre necrosis, marked eosinophilia with or without eosinophil abscess formation, proliferation of high endothelial venules, and sclerosis. The histological features suggest that epithelioid haemangioma is a proliferation of atypical endothelial cells, possibly neoplastic, that is associated with a variable inflammatory infiltrate, whereas Kimura's disease is primarily an inflammatory condition in which high endothelial venules are usually found.

Treatment of angiolymphoid hyperplasia of the external ear with carbon dioxide laser

Two women with long histories of angiolymphoid hyperplasia involving the left external ear were successfully treated with carbon dioxide laser vaporization. In one of these patients a previous treatment with argon laser photocoagulation had proved unsuccessful. Carbon dioxide laser vaporization can be advantageous in the treatment of angiolymphoid hyperplasia, especially when the patient is not a good candidate for cold steel surgery or when the disease process involves confined or convoluted structures such as those on the external ear.

Eosinophil chemotactic factor in tumour tissue from a patient with Kimura's disease

An extract of tumour tissue from a patient with Kimura's disease was tested for eosinophil chemotactic activity using the Boyden chamber method. Eosinophil chemotactic activity was detected in the tissue extract, and after gel filtration maximum activity was found in the fraction with a molecular weight of approximately 1000 daltons. This factor may play a role in the tissue eosinophilia which occurs in Kimura's disease.

Angiolymphoid hyperplasia with eosinophilia-acquired port-wine-stain-like lesions: attempt at treatment with the argon laser

An unusual case of angiolymphoid hyperplasia with eosinophilia (ALHE) simulating port-wine stain in a 50-year-old woman is reported. The lesions of ALHE are typically papules or subcutaneous masses that range from light pink to red-brown in color. In addition to the usual histologic findings of ALHE, the biopsy in our patient showed some fibrin-like material and fibrous long-spacing collagen on ultrastructural examination. This unusual lesion necessitates biopsy because the differential diagnosis includes port-wine stain, sarcoidosis, lupus erythematosus, and non-Hodgkin lymphoma (mycosis fungoides). Many different forms of treatment have been attempted for ALHE including radiotherapy, cytotoxic chemotherapy, corticosteroids, and antibiotics. The lesions in our patient responded to argon laser therapy and surgical excision, though there has been recurrence on the border of the treated area. Because laser energy is noncumulative in the tissues and effective in removing the lesions, we recommend it as the treatment of choice for these lesions.

Kimura's disease and angiolymphoid hyperplasia with eosinophilia: two distinct histopathological entities

The relationship between the disorder known in Japanese and Chinese literature as Kimura's disease and that known in Western literature as angiolymphoid hyperplasia with eosinophilia (ALHE) has been the subject of debate. Many reports have used the terms synonymously. We have reviewed the histological and clinical features of 4 cases, all occurring in Caucasians, 2 of which are typical of Kimura's disease and 2 of ALHE. Analysis of the cases indicates that the histological features of the 2 disorders are sufficiently different to warrant their recognition as 2 distinct entities. The histological and clinical features of Kimura's disease are most consistent with an allergic or autoimmune process in which blood vessels, lymphocytes and eosinophils participate. Those of ALHE suggest a primary, probably neoplastic disorder of vascular endothelium with a variable and secondary inflammatory response. Although there is some clinical overlap between patients with the 2 disorders, the histological features are distinctive, and the 2 terms should not be used synonymously.

Kimura's disease: a clinico-pathological study of 21 cases and its distinction from angiolymphoid hyperplasia with eosinophilia

Kimura's disease is a chronic inflammatory condition producing subcutaneous tumour-like nodules chiefly in the head and neck region. It is characterized histologically by lymphoid follicles, intense aggregations of eosinophils, vascular proliferation and fibrosis. Superficial lymph nodes and parotid glands are sometimes involved. The lesions may persist unchanged for years and new ones are apt to occur. Recurrences are also common. There are no systemic manifestations apart from peripheral blood eosinophilia. The lesion has been recognised as a distinct clinicopathological entity in the Far East for over 40 years. We describe 21 cases of Kimura's disease and discuss its relationship to angiolymphoid hyperplasia with eosinophilia. Although the pathogenesis and etiology of both these lesions are unknown we believe that there are sufficient significant clinical and pathological differences to justify their separation.
