Symptomatic dermographism (SD), also known as urticaria factitia, is the most common form of chronic inducible urticarias, occurring in approximately 2%-5% of the general population. 1 It typically presents as stripe-shaped wheals after shear force is applied to the skin, accompanied by a local itching and/or burning sensation. The etiology of SD is still unknown. It has been indicated that SD may be associated with systemic use of penicillins, famotidine and atorvastatin, and SD following amoxicillin and cefaclor-induced urticarial rash has been reported. 2 Minocycline is widely used in the treatment of acne, rosacea, and other inflammatory skin diseases. The association of minocycline with SD has not been previously reported.Herein, we present four cases of SD induced by oral minocycline.

Herpes zoster (HZ), also called shingles, characterized by unilateral painful erythema blister, is a common disease and patients are often referred to the dermatology department first at onset. The management of HZ in the acute phase includes antiviral drugs and analgesics, and adjuvant agents like gabapentin, tricyclic antidepressants, or glucocorticoids.

Here, we report a case of herpes zoster with severe acute inflammations
