Calcinosis cutis is a disorder caused by abnormal deposits of calcium phosphate in the skin. We describe a case of dystrophic calcinosis cutis caused by self injections of Diphenhydramine hydrochloride. The patient was 78-year-old man who presented with an intractable 6×2cm ulceration and subcutaneous deposits of calcium on his left upper arm. Thirty years ago, he had self-administered a large number of Diphenhydramine hydrochloride injections for insomnia. So this case was diagnosed as dystrophic calcinosis cutis caused by the local injury. In our case, minimum debridement was considered to be effective and the post operative course was uneventful. When choosing a surgical treatment for dystrophic calcinosis cutis, it is particularly important to consider each case individually.
