Alopecia areata and vitiligo are autoimmune diseases, both associated with multiple autoimmune comorbidities. Many studies show colocalization of these diseases at the same anatomical site. Here, we have a case where both disorders were reported to present in the same patient. Diphenylcyclopropenone (diphencyprone, DCP) is used in the treatment of alopecia areata and may induce vitiligo in some patients. We report on one case of vitiligo that was induced by DCP during therapy for alopecia universalis. Alopecia areata and vitiligo share many susceptibility genes. Follicular melanocyte destruction may represent the link between the two diseases.

Acquired brachial cutaneous dyschromatosis (ABCD) is an acquired disorder of pigmentary change that presents as chronic, asymptomatic, geographic-shaped, gray-brown patches, consisting of mixed hyper and hypopigmented macules on the dorsal aspect of the forearms. We report a case of a 40-year-old male who presented with asymptomatic, multiple brown-colored macules on the outer aspects of both arms. He had no history of hypertension and had never taken angiotensin converting enzyme inhibitors. He also denied chronic sun exposure history. Histologic examination demonstrated epidermal atrophy, increased basal layer pigmentation, and several telangiectatic vessels in the upper dermis. Solar elastosis was not remarkable. The patient's clinical and histopathologic features were consistent with a diagnosis of ABCD. Poikiloderma of Civatte, melasma, acquired bilateral telangiectatic macules and other pigmentary disorders should be considered in the differential diagnosis of ABCD. Herein, we report a case of ABCD in a middle-aged male without hypertension and medication.

Pemphigus is a group of autoimmune diseases characterized by the formation of erosions and/or flaccid bullae of the skin and/or mucosae. The definition "drug-induced pemphigus" has been coined to indicate cases of pemphigus with clinical, histological and immunopathologic features similar to those of the idiopathic disease but induced by systemic ingestion or local use of some drugs. The present authors analyzed a case series of three case reports with clinical and pharmacological features compatible with the diagnosis of angiotensin converting enzyme inhibitors or angiotensin II receptor blocker drug-induced pemphigus. The patients were visited by the dermatological Unit of Magna Graecia University in Catanzaro. All suspected drug induced pemphigus were treated by suspending the suspected drug and by starting a treatment with systemic corticosteroid drugs, leading to a remission of the clinical manifestations in some months. When a drug induced bullous disease is probable, it is necessary to interrupt the suspected substance and to start a high dose treatment with corticosteroid drugs to resolve the clinical case in a short period of time.

Interstitial granulomatous drug reaction is a rare condition presenting as erythematous-to-violaceous plaques on the lateral trunk, axillae, buttocks, and thighs. Calcium-channel blockers, angiotensin converting enzyme inhibitors, beta-blockers, and statins have been described as drugs that can trigger interstitial granulomatous drug reaction. We present a case of interstitial granulomatous drug reaction related to hydrochlorothiazide and our approach to management of this condition. The diagnosis was confirmed with a skin biopsy and a rechallenge of hydrochlorothiazide, which exacerbated the patient's symptoms. The patient improved significantly with rigorous photoprotection, combination dapsone-alitretinoin therapy, and discontinuation of hydrochlorothiazide.
