Dermatofibrosarcoma protuberans

Abstract

Introduction: Dermatofibrosarcoma protuberans (DFSP) is an uncommon skin tumor with a low-to-intermediate grade of malignancy, characterized by progressive growth and a propensity for local recurrence. In this series, we are analyzing the clinicopathological spectrum of DFSP cases. Materials and Methods: A retrospective study of 12 patients with DFSP who were diagnosed at our institute over the last 2 years (2018–2020) was performed. Results: The clinicopathological spectrum and immunohistochemistry of DFSP cases were studied with one case with lymph node metastasis, which is a rare entity, and two cases of the fibrosarcomatous DFSP were also diagnosed and warrant a special mention. Conclusion: Pathologists should be aware of metastasis and unusual variants while reporting dermatofibrosarcoma.
