MORAIS, Patrícia Motta de; SCHETTINI, Antônio Pedro Mendes; CHIRANO, Carlos Alberto and NAKAMURA, Greicianne. Bednar tumor (pigmented dermatofibrosarcoma protuberans): a case report. An. Bras. Dermatol. [online]. 2005, vol.80, n.3, pp. 273-276. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962005000300008.
Bednar tumor is a rare skin neoplasm, considered to be a pigmented variant of dermatofibrosarcoma protuberans. Diagnosis is confirmed through histopathologic examination and immunohistochemical evaluation. Bednar tumor is aggressive locally and recurrences are frequent, but metastases are rare. The most appropriate therapeutic procedure is Mohs' micrographic surgery. The case report presents a 35-year-old patient with this rare neoplasm in which the diagnosis was established through histopathologic examination and immunohistochemical study. The importance is emphasized for dermatologists to be attentive for diagnostic suspicion and have available the necessary means to confirm the diagnosis in order to adopt the best procedure.
