ABSTRACT
This chapter presents the case study of a 28-year-old woman. A 28-year-old woman presents with multiple naevi, which had gradually appeared over many years, since puberty. She denies any history of obvious change in her moles but feels she has had too many to keep a proper check on them. She has multiple naevi over her trunk and limbs, all of which have a similar appearance, with a slightly irregular border and varying shades of brown, tan and light red. The patient has multiple atypical naevi, as do her family and a first-degree relative with a malignant melanoma. Atypical melanocytic naevi occur sporadically or as part of the familial atypical naevus syndrome and are potential precursors for malignant melanoma. Patients with the atypical naevus syndrome have a far greater risk of developing melanoma than those with a small number of atypical moles. Patients diagnosed with this syndrome should undergo life-long surveillance due to the potential risk of development of malignant melanoma.
