SUMMARY:
A 50-year old female patient presented with an ulcerated scalp lesion temporo-occiptal. Under the suspicion of a squamous cell carcinoma a complete delayed Mohs excision was performed. The defect was closed by a rotational flap. Histopathological investigations revealed surprisingly a collision tumor of syringocystadenoma papilliferum and basal cell carcinoma. Such a finding is very rare. During a follow-up of 9 months no recurrence was observed.
