We report a case of syringocystadenoma papilliferum (SCAP) combined with tubular papillary adenoma (TPA) arising on the chest of a 45-year-old Japanese woman. Histopathological examination revealed the characteristic findings of SCAP in the superficial part of the lesion and those of TPA in the deeper part. We reviewed the English literature about this combination. SCAP and TPA have the same cellular components, but show differences of the general structure. The combination of these two neoplasms is more frequent than expected by most dermatopathologists or pathologists. This combination is frequently seen in patients with nevus sebaceus (NS), but it is also found in patients without NS.
