Protruding Digital Lesion

A 42-Year-old mechanic comes to the clinic complaining of a small, painless bump on his finger that has been gradually increasing in size over the past few months. It is not causing any discomfort, but he is concerned about its appearance and wants to have it evaluated. He denies pain, itching, bleeding or any history of trauma or injury to the area. Physical examination revealed a well-demarcated, firm, skin-coloured, hyperkeratotic papule noted on the lateral aspect of the right index finger's proximal phalanx, as shown in the image. The lesion measures approximately 1 cm in diameter. No other similar lesions are observed on the fingers or elsewhere on his body. The rest of the skin examination is unremarkable. Based on the patient’s history and physical examination.
