We present a unique case of syringocystadenoma with malignant transformation into syringocystadenocarcinoma papilliferum and coexisting trichoblastoma arising de novo in a scalp swelling of long duration in a 78-year-old woman. Syringocystadenocarcinoma papilliferum was described by the World Health Organization as an extremely rare malignant adnexal tumor of apocrine origin with varied histology with some cases reported in literature.
