(a) At an objective examination, it is possible to notice an exudative lesion of the skin with a violet halo index of subcutaneous tissue infection compatible with a suppurative bacterial infection. The patient stated he had pain on the inspection site. Moreover, pain, tumor, calor, rubror, all signs of acute inflammation, were detectable. Clinical diagnosis of phlegmon was made. (b) On physical examination, it is possible to notice two lesions arising in the tattooed area. The lesions are excavated, with a clean margin and a fibrous bottom, where it is possible to see the onset of skin infection; then, infection is confirmed through microbiological tests. Clinical signs of subcutaneous tissue inflammation, i.e., pain, tumor, and perilesional rubror were detectable. Circular areas of superficial flaking, as reported by the patient, also occurred as primary lesions followed by skin ulceration.
