Tubulopapillary hidradenoma-like tumor of the mandible

Tubulopapillary hidradenomas are uncommon benign tumors of the dermis, most commonly occuring in the skin of the head or of the extremities. Complete excision is generally curative and recurrences are rare. The authors describe an unusual case of an intraosseous tubulopapillary hidradenoma of the mandible that recurred 1 year after initial curretage and required en-bloc resection.
