Cutaneous adverse drug reactions (CADR) are an unfavorable condition caused by drugs manifesting on the skin. Exanthemata's drug eruption is the most common manifestation. The symptoms are itchy rash and burning sensation at the lesion and can occur along with fever and pain. The most common types of drugs inducing CADR are antibiotics, non-steroidal, anti-inflammatory drugs (NSAID), and anticonvulsants. A 48-year-old woman with complaints of itching on the chest followed by both arms and legs. Complaints arose 8 days after surgical excision of the craniometrical tumors when the patient was treated with polypharmacy medications. The description of the lesions is regional, multiple, well-defined maculopapular lesions with erythema, crusts, and excoriation. The working diagnosis is exanthemata's drug eruption with ceftriaxone, paracetamol, and phenytoin as the suspected causative drugs. No history of drug allergy was known before. Polypharmacy can cause difficulty in making clinical decisions for discontinuing the suspected drugs and cause patient's comorbidity left untreated. Therefore, it is important to identify the type of drugs and drug interaction causing cutaneous adverse drug reactions and minimize the use of polypharmacy therapy if possible.

Gray patch type of tinea capitis is one of clinical manifestations of dermatophytosis in scalp and hair that usually occurs in tropical areas such as Lombok, mainly taking place in 6-month-old to 12-year-old children and could cause hair loss. The risk factors are direct contact with microorganisms from animals, humans, and soil. In addition, indirect contact with fomite and inappropriate use of topical corticosteroid. We are reporting two cases, two siblings, a 7-yearold girl and 11-year-old boy with gray patch tinea capitis. The risk factors in these two patients were exposure to cats, sleeping in the same bed, and the use of betamethasone valerate cream. On Wood's lamp examination, a yellow-green fluorescent was found and on 20% potassium hydroxide (KOH) examination, an ectothrix spore was found. The systemic therapy given to both patients was ultramicrosize griseofulvin, vitamin D3, cetirizine, and topical therapy, which is terbinafine cream 1%. Identification of risk factors in this case is the main thing in determining effective and efficient management.
