Abstract
- Subungual melanoma is a variant of acral lentiginous melanoma and is thought to carry a poor prognosis due to difficulties in early diagnosis. Classical management of subungual melanoma is based on the radical surgery of distal phalanx amputation. Instead, conservative treatment with non-amputative wide excision of the nail unit followed by reconstruction has been insufficiently reported, especially in Korea. A 71-year-old woman presented with dark brownish longitudinal bands on her right thumbnail. Punch biopsies from the nail matrix and nail bed showed proliferation of atypical melanocytes without dermal involvement. We describe a case of subungual melanoma in situ of the right thumb, and a non-amputative surgical management which aims to provide adequate clearance of the lesion with minimal morbidity and satisfactory preservation of function for the patient.
