Successful treatment of angiolymphoid hyperplasia with eosinophilia and Kimura's disease in the same patient with surgery

Until now, there have only been two cases describing the coexistence of angiolymphoid hyperplasia with eosinophilia (ALHE) and Kimura's disease in one patient. Herein, we report the previous case of recurrent ALHE and Kimura's disease that was successfully treated with surgery.     

Angiolymphoid hyperplasia with eosinophilia and Kimura disease overlap,with evidence of diffuse visceral involvement

A relationship between Kimura disease (KD) and angiolymphoid hyperplasia with eosinophilia (ALHE) has been debated. Given substantial clinical and histological overlap, these entities were once considered to represent a disease spectrum; however, they are now widely considered to be nosologically distinct. A diagnosis of either condition is further complicated by resemblance to various malignancies, which must be carefully excluded. Coexistence of ALHE and KD in a patient is extremely rare, with only four cases reported in the English literature. We report what is to our knowledge the first case of ALHE and KD overlap with evidence of diffuse visceral involvement.     

Profound proliferating angiolymphoid hyperplasia with eosinophilia of pregnancy mimicking angiosarcoma

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular proliferation that clinically manifests as nodules and papules of the head and neck region. We report a profound, rapidly proliferating case of ALHE in a 3-week postpartum woman that clinically mimicked angiosarcoma. The clinical and histologic features of ALHE, Kitamura disease, and cutaneous angiosarcoma are reviewed, and the relationship between ALHE and pregnancy is discussed.     

Co-existence of lichen amyloidosus and angiolymphoid hyperplasia with eosinophilia

Summary Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon benign vascular tumour. It presents with small, dull red papules or nodules usually on the ears and preauricular areas and only 20% of lesions are multiple. We report a case of multiple scattered lesions of ALHE in a patient who subsequently developed lichen amyloidosus. Cases of lichen amyloidosus in association with Kimura's disease have been reported previously, but there are no reports of lichen amyloidosus with ALHE. The coexistence of these two conditions implies that ALHE is an inflammatory disorder, as an inflammatory process resulting in basal layer damage is necessary for the occurrence of lichen amyloidosus.     

Angiolymphoid hyperplasia with eosinophilia and Kimura's disease – a clinical and histopathological comparison

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign vascular neoplasm mainly affecting middle‐aged women. Lesions typically affect the head and neck region. ALHE is considered a distinct disease entity different from Kimura's disease, a benign reactive lymphoid proliferation that is predominantly seen in young Asian men although it can affect all ethnic groups. In contrast to ALHE, Kimura's disease is typically associated with peripheral blood eosinophilia, increased serum IgE and lymphadenopathy. Several case reports suggest an overlap between ALHE and Kimura's disease. We review the current literature and discuss whether AHLE and Kimura's disease might represent two extreme variants of the same disease entity.     

Epithelioid Hemangioma (Angiolymphoid Hyperplasia with Eosinophilia) in Zosteriform Distribution

Epithelioid hemangioma (EH) or angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon benign disease. We report an unusual case of EH (ALHE) that arose on the lower back in a zosteriform array. The presence of the characteristic histological appearance of plump endothelial cells with hobnail-like protrusions led to the diagnosis of EH (ALHE). Histological examination of the lesion also revealed the existence of arteriovenous shunts, the possible factor contributing to the pathogenesis of EH (ALHE).     

Angiolymphoid hyperplasia with eosinophilia associated with arteriovenous malformation: a clinicopathological correlation with angiography and serial estimation of serum levels of renin, eosinophil cationic protein and interleukin 5

We present a case of angiolymphoid hyperplasia with eosinophilia (ALHE) affecting the auricular area of a 31-year-old man, which clinically mimicked arteriovenous malformation (AVM). The histology and laboratory data distinctively revealed ALHE, while angiography demonstrated typical findings of AVM. Although several reports have hitherto mentioned the relationship between ALHE and AVM, the aetiology of the disease remains unknown. During the 3 years treatment course, we performed angiography several times to assess the efficacy of the treatments and compared the clinical and pathological findings, based on the hypothesis that AVM might be a cause of ALHE. This study showed first, that the clinicopathological findings of ALHE correlated with the extent of AVM shown by angiography, so that AVM could be a primary cause of ALHE. Secondly, systemic corticosteroids and local irradiation therapy produced only a temporary effect on the inflammatory changes of ALHE; therefore, surgical resection is recommended as a curative treatment. Thirdly, the patient's serum levels of renin, eosinophil cationic protein and interleukin 5 corresponded closely with the clinical course of ALHE.     

Angiolymphoid hyperplasia with eosinophilia affecting the scrotum: A rare case report with molecular evidence of T‐cell clonality

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare, benign entity of unknown pathogenesis. It often presents as painful or pruritic intradermal or subcutaneous red to brown papules or nodules on the head and neck of young adults. A 38‐year‐old man had a gradually enlarging and mild pruritic plaque on the scrotum for half a year. Pathological findings showed dermal proliferation of anomalous blood vessels lined by plump endothelium with a significant perivascular inflammatory infiltrate composed of lymphocytes, histiocytes, scattered plasma cells and many eosinophils. They were consistent with the diagnosis of ALHE. In addition, the inflammatory infiltrate was analyzed by immunohistochemistry and T‐cell receptor (TCR) gene rearrangement. They were mostly CD3⁺ T cells and a monoclonal T‐cell population. To the best of our knowledge, this is the first case of ALHE affecting the scrotum to be reported in the published work. We present this case to expand the anatomical distribution of this rare tumor. The molecular study of our case supports that ALHE might be a low‐grade T‐cell lymphoproliferative disorder.     

D2-40 highlights lymphatic vessel proliferation of angiolymphoid hyperplasia with eosinophilia

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign, uncommon idiopathic condition, characterized by cutaneous papules or nodules, whose etiopathogenesis is still unclear. It has been considered an angioproliferating lesion (epithelioid hemangioma) since histologically it is marked by a proliferation of blood vessels, accompanied by an inflammatory infiltrate, consisting mainly of lymphocytes and eosinophils.
We present a case of ALHE assessed immunohistochemically for D2-40—a new marker for lymphatic endothelial cells. A biopsy specimen obtained from the same anatomical area of a healthy individual served as a normal control. The ALHE specimen showed increased number of lymphatic vessels when stained for D2-40, whereas the endothelial cells lining blood vessels were negative. The specificity of D2-40 for lymphatic vessels was further substantiated by studying Factor VIII-related antigen expression in consecutive sections of both ALHE and the control specimen. A reverse pattern was appreciated—blood vessels showed Factor VIII positive labeling, whereas lymphatic endothelial cells remained unlabeled.
We therefore assume that apart from the lymphocytic infiltrate in the lesion, the recognized lymphoid component in ALHE is due to lymphatic vessel proliferation as well. Hence, this condition may be considered as possibly derived from lymphatic endothelium.     

Polymerase chain reaction (PCR) for human herpesvirus 8 and heteroduplex PCR for clonality assessment in angiolymphoid hyperplasia with eosinophilia and Kimura's disease

BACKGROUND: Recently, human herpesvirus 8 (HHV-8) has been isolated from almost all cases of Kaposi's sarcoma. It has not been found in most cutaneous hemangioproliferative disorders other than Kaposi's sarcoma. Benign vascular lesions including Kimura's disease were not found to contain the HHV-8 DNA sequence. However, there has been contradictory data concerning the presence of HHV-8 in angiolymphoid hyperplasia with eosinophilia (ALHE). Clonality studies in ALHE and Kimura's disease were rare. METHODS: We performed polymerase chain reaction (PCR)-based analysis to determine whether HHV-8 is present and heteroduplex analysis of rearranged T-cell receptor (TCR) gene for clonality assessment in paraffin-embedded skin biopsy samples of 7 ALHE and 2 Kimura's disease, taken from immunocompetent patients. RESULTS: HHV-8 could not be identified in all the cases of ALHE and Kimura's disease. Although 2 cases (2/7) of ALHE and 2 cases (2/2) of Kimura's disease showed positive result for PCR analysis of TCR, all the cases were negative for heteroduplex-PCR. CONCLUSIONS: We suggest that HHV-8 may not involve in a pathogenetic role in ALHE and Kimura's disease and the failure to demonstrate clonality may be consistent with the reactive nature of these diseases and lack of malignant transformation. In addition, heteroduplex-PCR can be applied to confirm doubtful cases of lymphoma in that heteroduplex-PCR is more specific than PCR as seen in our study.     

Angiolymphoid Hyperplasia with Eosinophilia That Was Possibly Induced by Vaccination in a Child

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vasoproliferative disease of an unknown cause involving the skin or subcutaneous tissue of the head and neck, and particularly around the ear. It predominantly affects Caucasian adults during the third and fourth decades and it very rarely occurs in children. We experienced a case of ALHE in a 2-year-old Korean boy who had a firm, pruritic, skin-colored, subcutaneous nodule on his right upper arm. The histopathological findings were compatible with ALHE and they showed prominent vascular changes with epitheloid or histiocytoid endothelial cells surrounded by inflammatory cells, including a large proportion of eosinophils. This unusual distribution of the lesion and the young age of the patient may be associated with vaccination.     

Angiolymphoid hyperplasia with eosinophilia and Kimura's disease coexisting in the same patient: Evidence for a spectrum of disease

The relationship between angiolymphoid hyperplasia with eosinophilia (ALHE) and Kimura's disease has always been contentious. Initially, ALHE and Kimura's disease were thought to be conditions within the same disease spectrum, but it is now widely accepted that they are two separate disease entities. The two lesions may coexist in one patient. Thus, ALHE and Kimura's disease may be different manifestations of the one disease.     

A Case of Angiolymphoid Hyperplasia with Eosinophilia of the Lower Eyelid

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a subcutaneous angioproliferating tumor with a characteristic inflammatory infiltrate that consists mainly of lymphocytes and eosinophils. A 24-year-old man presented with a firm single asymptomatic erythematous papule on the lower eyelid. Histopathological findings showed a proliferation of blood vessels lined with epithelioid cells and perivascular infiltration of lymphocytes and eosinophils. We report a case of ALHE occurring on an unusual site.     

Angiolymphoid hyperplasia with eosinophilia: good response to photodynamic therapy

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon benign vascular disease of unknown pathogenesis, that occurs as solitary or multiple nodules or papules. Lesions are located mainly on the head, forehead and neck, and may be persistent and difficult to eradicate. We report a case of ALHE treated with aminolaevulinic acid photodynamic therapy (ALA‐PDT). Treatment consisted of two ALA‐PDT sessions with a 2‐week interval. Clinical evaluation, 8 weeks after treatment, showed marked improvement though not complete regression. The treatment was well tolerated. At follow‐up 4 months after treatment, the lesions were stable. We believe that PDT could be an alternative therapeutic approach for ALHE or could be used as a neoadjuvant treatment to reduce lesion size especially where size or site of lesions limits the efficacy or acceptability of other treatments. The lack of cumulative effects allows repeated treatments with ALA‐PDT, but long‐term follow‐up is advised for assessment of recurrence.     

Angiolymphoid hyperplasia with eosinophils. Case report and differentiation from Kimura disease

We report a 40-year-old patient, who presented with a nodular tumor at the scalp. The histological diagnosis was angiolymphoid hyperplasia with eosinophils (ALHE). Immunohistochemical staining of the proliferating vessels was characteristic for endothelial cells. The perivascular inflammatory infiltrate mainly consisted of CD4-positive lymphocytes. Recently it has become clear that Kimura disease, which was thought to be a variant of ALHE, can be distinguished from ALHE by clinical, histological and immunohistochemical criteria and constitutes its own clinical identity. While ALHE is a localized proliferation of endothelial cells, Kimura disease is a proliferation of lymphoid cells characterized by invasive growth and possibly lymphadenopathy.     

Angiolymphoid hyperplasia with eosinophilia successfully treated with imiquimod. A case report

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare disorder characterized by vascular proliferation, eosinophilia in peripheral blood samples and lymphocytosis. The etiology is unknown; this rare condition is generally seen in women. It often presents as multiple, grouped red nodules in the periauricular region, scalp line and neck. Numerous therapeutic approaches have been tried for ALHE including destructive techniques such as electrodesiccation, cryotherapy, surgical excision, radiotherapy or laser (argon, CO(2), pulse dye). We present an ALHE case that was treated successfully by using topical imiquimod cream.     

Localized soft tissue angiomatosis with subsequent development of angiolymphoid hyperplasia with eosinophilia

We report an unusual case of arteriovenous (AV) malformation (localized form of soft tissue angiomatosis): a reaction of angiolymphoid hyperplasia with eosinophilia (ALHE) developed over the lesion of this pre-existing AV malformation. To the best of our knowledge, there is no other report of ALHE in association with a pre-existing bona fide AV malformation. A 71-year-old woman consulted our clinic because a reddish, dome-shaped tumor on her preauricular region, present as a slightly elevated, skin-colored tumor since her childhood, had rapidly enlarged and become more elevated with color change during the preceding two months. The histological features of most of the lesion corresponded to those of soft tissue angiomatosis (localized form). The proliferative vessels underlying the soft tissue angiomatosis streamed out and welled into the dermis with an accompanying prominent inflammatory infiltrate composed of lymphoid cells and eosinophils: these histological features were characteristic of ALHE. The recent abrupt clinical changes in the tumor were considered to represent a reaction to the angiomatosis with development of ALHE.     

A case of angiolymphoid hyperplasia with eosinophilia (ALHE) of the upper lip

Angiolymphoid hyperplasia with eosinophilia (ALHE) is clinically characterized by intradermal or subcutaneous papules and/or nodules usually occurring in young adults. Lesions in the oral mucosa are extremely rare. We report a case and review the literature of ALHE cases involving the oral mucosa. A 40-year-old man presented with a painless, 20 x 20 mm, submucosal nodule on the upper lip. Histological examination of lip biopsy specimens revealed an increase in many small vessels. The vascular walls consisted of prominent endothelial cells with a histiocytoid appearance, which protruded into the lumen. Many eosinophils and lymphocytes were also seen around the vessels. The diagnosis of ALHE was made from the above findings.     

Propranolol: a novel treatment for angiolymphoid hyperplasia with eosinophilia

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon, idiopathic disease that manifests as dermal or subcutaneous red or brown papules or nodules, most commonly on the head and neck. Histologically, ALHE is characterized by vascular proliferation with epithelioid endothelial cells with surrounding lymphocytic and eosinophilic infiltrate. There may be an accompanying serum eosinophilia and local lymphadenopathy. We report a case of a 32‐year‐old woman who presented with multiple erythematous nodules in the periauricular area and the vertex of her scalp. The nodules had been present for several months. Surgical removal of one of the lesions confirmed the histological diagnosis of ALHE. The patient was started on oral propranolol (40 mg once daily) in an effort to reduce the vascular component of the lesions. Within 6 weeks, the patient noted that several of the lesions had decreased in size, and all were less erythematous. Propranolol was subsequently stopped within a few months of initiating treatment. One lesion recurred over a year later, and propranolol was then restarted. No new lesions occurred after 2 years of follow‐up.     

Angiolymphoid Hyperplasia with Eosinophilia Mimicking Multiple Cylindromas: A Rare Case Report

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare and idiopathic vascular disorder. It is characterized by red to brown papules and nodules, typically localized on the head and neck, particularly around the ear as singular or multiple lesions. Although ALHE is a benign disease, lesions are often persistent and difficult to eradicate. Young to middle age women are more commonly affected. The histological examination corresponds to a florid vascular proliferation with atypical endothelial cells surrounded by a lymphocytic and eosinophilic infiltrate. We describe an elderly male with multiple nodular lesions over the scalp mimicking cylindromas; the histological examination was consistent with ALHE.
