Overview
Angiolymphoid hyperplasia with eosinophilia [1] is defined as red-brown, dome-shaped, dermal papule or nodule, present in the head or neck, specifically around the ears and on the scalp.[2]
Historical Perspective
- [Disease name] was first discovered by [scientist name], a [nationality + occupation], in [year] during/following [event].
- In [year], [gene] mutations were first identified in the pathogenesis of [disease name].
- In [year], the first [discovery] was developed by [scientist] to treat/diagnose [disease name].
Classification
- [Disease name] may be classified according to [classification method]
into [number] subtypes/groups:
- [group1]
- [group2]
- [group3]
- Other variants of [disease name] include [disease subtype 1],
[disease subtype 2], and [disease subtype 3].
Pathophysiology
- The pathogenesis of angiolymphoid hyperplasia with eosinophilia is characterized by red to brown papules or nodules dislocated in the dermis or subcutaneous tissue.
- Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare and idiopathic vascular disorder.
- Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon benign lesion, primarily occurring in the head and neck.
- The [gene name] gene/Mutation in [gene name] has been associated with
the development of [disease name], involving the [molecular pathway] pathway.
- On gross pathology, [feature1], [feature2], and [feature3] are
characteristic findings of [disease name].
- On microscopic histopathological analysis, florid vascular proliferation with atypical endothelial cells surrounded by a lymphocytic and eosinophilic infiltrate are characteristic findings of angiolymphoid hyperplasia with eosinophilia.
Causes
- Angiolymphoid hyperplasia with eosinophilia may be caused by either allergic reactions, traumas, or autoimmune disorders.
Differentiating Angiolymphoid hyperplasia with eosinophilia from other Diseases
- Angiolymphoid hyperplasia with eosinophilia must be differentiated from other diseases that cause swelling of face and neck, such as:
- Kimura’s disease
Epidemiology and Demographics
- The prevalence of [disease name] is approximately [number or range] per 100,000 individuals worldwide.
- In [year], the incidence of [disease name] was estimated to be [number or range] cases per 100,000 individuals in [location].
Age
- Patients of all age groups may develop [disease name].
- [Disease name] is more commonly observed among patients aged [age range] years old.
- [Disease name] is more commonly observed among [elderly patients/young patients/children].
Gender
- [Disease name] affects men and women equally.
- [Gender 1] are more commonly affected with [disease name] than [gender 2].
- The [gender 1] to [Gender 2] ratio is approximately [number > 1] to 1.
Race
- There is no racial predilection for [disease name].
- [Disease name] usually affects individuals of the [race 1] race.
- [Race 2] individuals are less likely to develop [disease name].
Risk Factors
- Common risk factors in the development of angiolymphoid hyperplasia with eosinophilia are allergic reactions, traumas or autoimmune disorders.
Natural History, Complications and Prognosis
- The majority of patients with [disease name] remain asymptomatic for
[duration/years].
- Early clinical features include [manifestation 1], [manifestation 2],
and [manifestation 3].
- If left untreated, [#%] of patients with [disease name] may progress
to develop [manifestation 1], [manifestation 2], and [manifestation 3].
- Common complications of [disease name] include [complication 1],
[complication 2], and [complication 3].
- Prognosis is generally [excellent/good/poor], and the [1/5/10year
mortality/survival rate] of patients with [disease name] is approximately [#%].
Diagnosis
Diagnostic Criteria
- The diagnosis of [disease name] is made when at least [number] of the
following [number] diagnostic criteria are met:
- [criterion 1]
- [criterion 2]
- [criterion 3]
- [criterion 4]
Symptoms
- [Disease name] is usually asymptomatic.
- Symptoms of [disease name] may include the following:

- [finding 5]
- [finding 6]
Laboratory Findings
- There are no specific laboratory findings associated with [disease
name].
- A [positive/negative] [test name] is diagnostic of [disease name].
- An [elevated/reduced] concentration of
[serum/blood/urinary/CSF/other] [lab test] is diagnostic of [disease name].
