E-mail: [email protected] A 20-year-old woman with no medical history presented to our dermatology department with a painless swelling over her left middle finger. The lesion had developed 2 weeks earlier as a small “red dot”, which then developed continu- ously into a large nodule. Clinical examination revealed a 1.5-cm diameter large nodule with a central subsided crust and erythematous demarcation on the left middle finger (Fig. 1). Otherwise there were no further pathological clini- cal findings: The patient was healthy, afebrile, and her finger was not tender on direct palpation, did not feel hot, was able to move fully, and was neurovascularly intact. Furthermore, there was no palpable lymphadenopathy. Blood count and clinical chemistry did not show any pathological findings. What is your diagnosis? See next page for answer. Fig. 1.
