Abstract:
Syringocystadenomapapilliferum is an extremely rare benign adnexal tumor of the scalp and face region. This is a report of the case of a female patient with syringocystadenomapapilliferum originating from the bony cartilaginous junction of the external auditory canal. A provisional diagnosis of an inflammatory polyp was made based on the clinical and radiological findings. Diagnosis was established only after the histopathological examination. This article represents a report of a rare skin disease and a rare site of affection. It emphasizes the role of histopathology in the diagnosis of such a condition with debatable clinical and radiological findings.
