Abstract
Cutaneous epithelioid angiomatous nodule is a rare benign vascular tumour of the skin with characteristic microscopic features, of which 65 cases have so far been reported after the initial description of this entity in 2004. We present here a new typical case of this rare lesion and provide a comprehensive review of all the previously published cases, delineating the salient clinicopathological features of this rare tumour.

Abstract
BACKGROUND The status of cutaneous epithelioid angiomatous nodule (CEAN) as a distinct entity remains controversial. This study investigated the relationship between CEAN and epithelioid hemangioma/angiolymphoid hyperplasia with eosinophilia (ALHE). METHODS Data of seven lesions with CEAN features from four cases (Cases 1-4:61-year-old, 76-year-old, 53-year-old, and 21-year-old men, respectively) were investigated. RESULTS Cases 1 and 2 showed multiple lesions in the head and neck region, but Cases 3 and 4 showed solitary lesions on the back and scalp, respectively. Moreover, the histopathologic findings of the lesions of Cases 1 and 2 were consistent with those of conventional epithelioid hemangioma or classic cutaneous ALHE. Diffuse immunoexpression of FOSB was observed in Cases 1 and 2, but FOSB split signals were absent in break-apart fluorescence in situ hybridization (FISH). In contrast, the histopathologic findings of the lesions of Cases 3 and 4 were consistent with those of cellular-type epithelioid hemangiomas. Diffuse immunoreactivity for c-FOS was observed in Cases 3 and 4, and split signals of FOS were present in break-apart FISH in Case 3. CONCLUSIONS This study demonstrated that the seven tumors with CEAN features could be reclassified under the epithelioid hemangioma/ALHE group, although the small sample size is a limitation.
