Adamantinoma associated with botryomycosis: the first report of this rare association after trauma.

A 27-year-old man presented with swelling and inflammation of his right tibia, which had been present for nearly 3 years. It apparently was associated with an injury that was sustained to the right leg when it was struck against a tree stump, which had led to immediate swelling. There were no other symptoms and no history of fever or weight loss. The right tibia was swollen to twice the size of the left and the skin was indurated with numerous crusted lesions and some sinus-like areas, but no ulceration of the skin surface was apparent. We report for the first time to our knowledge a unique case of both botryomycosis and adamantinoma in the right tibia of the same patient at an area of previous trauma. Pathologists, clinicians and radiologists should be aware that both lesions can occur together. Although both botryomycosis and adamantinoma usually have a history of trauma, as in our patient, a causal relationship will need more cases to establish a possible link.
