It is usually seen in young adults and most commonly affects limbs. The lesion is seen equally in both sexes. This vascular tumor is rare in the world and, according to our acknowledge, only one case has been reported in Iran. In this case report, we described the second case of targetoid hemosiderotic hemangioma. Material and Methods: The patient is an 8 years old boy with a targetoid asymptomatic red popular lesion on his lower leg from 5 years ago .The lesion was completely excised. Skin biopsy showed dilated vascular spaces with hobnail endothelial cells in the superficial dermis accompanied with narrower vessels in the deep dermis which was compatible with targetoid hemosiderotic hemangioma. In a follow up period of three years the lesion did not recur. Conclusion: Distinction between targetoid hemosiderotic hemangioma and malignant skin lesions such as melanoma, Kaposi sarcoma and angiosarcoma is necessary. Thus, knowledge of clinical picture and pathology of this lesion can prevent unnecessary aggressive procedures. Key words: Targetoid hemosiderotic hemangioma, Hobnail hemangioma.
