BACKGROUND: Generalized rash is amongst the most common conditions presented to practicing General Practitioners and common differentials include contact dermatitis, atopic eczema, sun-induced damage, drug eruption and general manifestations of systemic diseases or infections. MATERIALS AND METHODS: We illustrate with differential diagnoses our clinical case of a generalized rash in a 55-year-old man with pathognomonic signs of a diagnosis, which has received increasing global concern. CONCLUSION: Despite the array of available laboratory tests, a detailed history and physical examination is still of paramount importance to arrive at the most likely diagnosis for any patient with a generalized skin rash.
