Author Year Article type Number of patients Treatment Outcome Comments Bal et al. [9 ] 2013 Case report 1 (anal, primary) Standard <20% 5-year survival Richardson et al. [14 ] 2012 Case report 1 (brain, secondary) Chemo and surgery provide best outlook
Lee et al. [12 ] 2011 Case report/lit. review 1 Standard Prognosis of BCMM does not depend on the degree of balloon cell change, tumor size, nuclear atypia, or mitotic activity Kao et al. [11 ] 1992 Cohort study 34 Standard 57.5% died at 2–12 years from metastasis. 18.2% developed local recurrences: 15.2% alive with metastatic tumours 21.2% alive without evidence of disease Prognosis of BCMM usually correlates with the tumour thickness Peters and Su [15 ] 1985 Case report/lit. review 1 Standard Many balloon cell melanomas show only mild cellular atypia and minimal mitotic figures although the tumour has a malignant course. Fievez [16 ] 1984 Lit. review Unknown Unknown 6.3-year median survival Jakobiec et al.
