ABSTRACT

The purpose of this article is to present a case of phalanx osteoblastoma. We will start by saying that osteoblastoma is rare, it accounts for 1% of primary bone tumors; it is most frequent in the posterior spine, and is very unusual in the phalanges. Early diagnosis is desirable due to its similarity, mainly radiologic, with other entities that result in similar bone lesions. Clinical case. We present the case of a 39-year-old male who presented with swelling of the proximal phalanx of the 5th digit of the left hand that began one year before. The histopathologic study of the tumor lesion showed that it was composed of prominent osteoblasts. No mitoses were observed. En-block surgical resection of the lesion and curettage were performed.
