Unusual and Bizarre Forms of Melanoma

  • Guido Massi
  • Philip E. Leboit


In this chapter we group melanomas with unusual but characteristic features. A few of them have a peculiar architectural pattern (polypoid melanoma and verrucous melanoma) whereas others have distinct cytological features. Their singular characteristics occasionally make these lesions the cause of misdiagnosis. The lesions are: polypoid melanoma; verrucous melanoma; balloon cell melanoma; rhabdoid melanoma; signet ring melanoma; melanoma with plasmacytic features; melanoma with osteocartilagineous differentiation.
