The osteoma is a benign osseous tumor the origin of which is in the bone cortical. Statistically, it develops more in the bones that morphologically longer in young males. They are slow growth tumors and according to bibliographies, they are painless. (They are described like this from the point of view that they are uncommon tumors in the foot). However, the cases that I have treated have always been located at a digital level, have shown me that they are painful, due to the compression they exert on other adjoining structures. They are diagnosed via X-ray as an oval osseous mass and beside the bone cortical.
Surgery is recommended in those cases in which the osteoma causes discomfort and also when it causes aesthetic deformities as is usually the case in subungual osteomas (they are quite often young patients). The most important thing in this kind of surgery is to curette the osseous surface once the osteoma has been excised, in order to avoid a recidivation risk. It is imperative to make this surgery with X-ray support, to make sure that the proper osseous scaling has been carried out before finishing theoperation and obviously sending the excised tumors to pathologic anatomy in order to confirm the diagnosis completely.
From one of my cases, I will describe you schematically the steps to follow in this kind of surgery.
