Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon benign vasoproliferative condition, characterized by solitary or multiple pink to red-brown papules or nodules, most commonly on the head. Histologically, ALHE shows prominent lymphocytic and eosinophilic infiltration in addition to the proliferation of histiocytoid endothelial cells. The etiology and immunological abnormalities are not well-known. Here, we present the case of ALHE with CCR4 expression.
A 54-year-old woman referred to our department with a 2-year history of multiple red nodules without preceding trauma in the right temporal artery region. Clinical examination revealed three dome-shaped purpuric red nodules in line with the right temporal artery region [Figure 1]a. A skin biopsy specimen showed the proliferation of blood vessels with enlarged histiocytoid endothelial cells and massive infiltration of lymphocytes and eosinophils around the vessels in the dermis [Figure 2]a and [Figure 2]b. Lymphatic follicles and evident vasculitis were not found. Based on these findings, the diagnosis of ALHE was made. A careful interview revealed a past history of a red nodule on the right temporal region 10 years ago. Excisional biopsy had found the proliferation of blood vessels with mild infiltration of lymphocytes and eosinophils in the dermis [Figure 2]c and [Figure 2]d. Although she had been diagnosed as having hemangioma at that time, considering that vascular component predominated in early ALHE, we concluded that the nodule 10 years ago was also ALHE. She was treated with intralesional corticosteroids, resulting in flattening of the nodule [Figure 1]b.

The important differential diagnosis of ALHE is Kimura disease. Kimura disease and ALHE are similar conditions that involve the head and neck region and share several histopathologic features including lymphoeosinophilic infiltration and vascular proliferation. Based on these similarities, ALHE and Kimura disease were once considered to represent a disease spectrum. However, ALHE is currently regarded to be clinically and pathologically distinct from Kimura disease. For example, Kimura disease clinically presents a large subcutaneous mass, while ALHE shows papules or nodules like our case. Pathologically, Kimura disease is characterized by lymphoid follicles with germinal center formation and eosinophilic abscess and lacks the characteristic cytomorphological alterations of the endothelial cells seen in ALHE.
On the other hand, analysis on the differences in the immunological abnormalities between ALHE and Kimura disease has been limited. Katagiri et al. first found that mRNA expression levels of Th2 cytokines, such as interleukin (IL)-4, IL-5, and IL-13 in peripheral blood are increased in Kimura disease and that they decreased after treatment. In addition, Th2 cytokine-producing CD4+ T-cells are increased in the blood and IL-5 expression is upregulated in the lesional lymph node., These reports indicate that polarization to Th2 may be involved in the development of Kimura disease. On the other hand, there have been no reports detecting the presence of Th2 cells or Th2 cytokine expression in patients with ALHE, except for the report describing that Th2 cytokine inhibitor was effective in some ALHE cases. To assess the characters of lymphocytes in ALHE, we performed immunohistochemical analysis for GATA3, a master gene of Th2 cells, and T-bet, a master gene of Th1 cells in our case using mouse anti-GATA3 antibody (Nichirei Biosciences, Tokyo, Japan, clone L50-823) and rabbit anti-T-bet antibody (Cell Signaling, Danvers, MA, USA, clone D6N8B). There was much higher number of GATA3-positive cells compared to T-bet-positive cells in infiltrating lymphocytes [Figure 2]e, [Figure 2]f, [Figure 2]g, [Figure 2]h. GATA3/T-bet ratio was 2.72. We also examined the expression of CCR4, which is a representative Th2 chemokine receptor and express in eosinophil-rich diseases such as atopic dermatitis and asthma,, using a CCR4 staining kit (Kyowa Medex, Tokyo, Japan). We found that the moderate number of infiltrating lymphocytes expressed CCR4 [Figure 2]i and [Figure 2]j. Although it is hard to draw a conclusion as polarization toward Th2 cells was demonstrated at one point of the long disease course, these results suggest that Th2 cells might be associated with ALHE. In addition, mogamulizumab, a monoclonal antibody against CCR4, could be used in refractory or relapsing ALHE cases.
ALHE and Kimura disease could share common immunological features in lymphocytes. Consistently, the coexistence of ALHE and Kimura disease in the same patient has been reported. However, further studies with large sample sizes are desirable to establish whether Th2 cells are involved in ALHE development.
