[Vascularized tumor of the retroauricular skin]

An 84-year-old female patient with loss of hearing and otorrhoea went to an otolaryngologist. On examination, a polypoid mass in the auditory canal and a retroauricular skin lesion, possibly seborrheic keratosis, were found. Only the skin was submitted for histological examination and showed a cutaneous highly vascular lesion with an associated "zellballen" of clear cells without atypia. The initial diagnosis was that of a cutaneous glomangioma. Immunohistochemical findings favored diagnosis of a paraganglioma. Additional clinical information revealed a large mastoid tumor mass. Therefore, the findings were compatible with an jugulotympanic paraganglioma with infiltration of the overlying skin. This possibility was initially not considered in differential diagnosis, as cutaneous glomangiomas are relatively common (typically located on the hands). Cutaneous paragangliomas, however, are not reported.
