Background: Pigmented dermatofibrosarcoma is a rare tumor of the skin and constitutes 1–5% of all dermatofibrosarcoma. Most cases present as polypoid multinodular growth. Occasional cases may be atrophic. We report an extraordinary case with progressive infraorbital atrophy. Observation: A 24-year-old woman came to us for a diffuse bluish atrophic lesion over the left infraorbital area. The lesion progressed gradually over 2 years. Histologic examination revealed mature spindle cell proliferation in the lower dermis and hypodermis. Interspersed were some heavily pigmented melanocytes. Conclusion: We report an unusual case of progressive bluish discoloration and atrophy of the infraorbital area. This is a rare manifestation of dermatofibrosarcoma.
