The histopathologic characteristics of melanoma in FAMMM kindreds are not different from those seen in sporadic cases of melanoma and, thus, are not useful in diagnosing the syndrome. Superficial spreading melanoma (SSM) and nodular melanoma are the most frequently encountered histological melanoma subtypes in patients with CDKN2A mutations, which is consistent with the relative early age of onset.
