A 39-year-old male presented at the outpatient department with seven painless, non-itchy papules within a recent tattoo, as shown in the images. These papules emerged approximately three weeks after the patient received a sizable tattoo on the ventral aspect of the right thigh. Initially, the lesions exhibited rapid growth, followed by a later stabilization in their size. Upon physical examination, erythematous dome-shaped papules were observed unilaterally, ranging from 4 mm to 1 cm in diameter. Among the seven lesions, five appeared within the red-inked area and two within the black/grey-inked area. The papules were primarily capped with a thin crust. The patient had no significant medical history or accompanying symptoms, having previously received multiple tattoos without complications. Recent sun exposure was denied.
An excisional biopsy unveiled well-circumscribed symmetric tumors featuring a central keratin-filled crater. The cytologic atypia was mild, and the tumors were accompanied by neutrophilic micro-abscesses and a mixed cell infiltrate. Kindly, suggest an appropriate diagnosis with suitable treatment options.
