Background:
A subset of about 3-5% of melanoma patients present a second primary melanoma.
Observations:
We describe two cases of primary multiple synchronous melanomas consecutively observed in the last 6 months in our department in two male patients presenting multiple atypical nevi. In both patients, the second melanoma was diagnosed by the clinician who had identified the first one, but at the time of the first follow-up consultation, 3 months later. The delayed discovery of the second melanoma required another referral for surgery with additional discomfort for the patients. Concern about the first lesion (the thickest in both cases) probably rendered the second one less evident to both patients and clinician, until the first follow-up examination after excision of the first lesion.
Conclusion:
We stress the need for careful and thorough examination of the whole body surface at the time of detection of a cutaneous melanoma in subjects with multiple atypical moles because the finding of synchronous multiple melanomas is not uncommon.
