摘要
Microvenular hemangioma(MVH)is a rare,benign type of hemangioma that typically presents as a solitary,slow-growing,red-to-violaceous asymptomatic papule,plaque,or nodule.It most commonly locations of the lesions on the limbs and trunk,with no prior reports of MVH confined to the breast.We present the first reported case of multiple MVH confined to the breast in a 17-year-old female patient.The case is notable for its unique and atypical clinical features.Diagnosing MVH is challenging and requires routine pathological and im-munohistochemical staining.Histological testing revealed typical features of MVH,irregularly branched small or medium vascular interstitial spaces lined with benign endothelial cells and positivity for CD34 and CD31.This case emphasizes the need to consider MVH in the dif-ferential diagnosis of breast vascular lesions,particularly in young patients.It also underscores the importance of histological and immu-nohistochemical analyses for an accurate diagnosis.
