[A tumour mistaken for a scar]

Area of Science:

• Oncology
• Dermatology
• Pathology

Background:

• Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous soft tissue sarcoma.
• DFSP is characterized by local aggressiveness and a high recurrence rate, despite rare metastasis.
• Clinical presentation can be variable, leading to diverse differential diagnoses.

Observation:

• A 50-year-old male presented with a long-standing, painful scar on his back.
• A biopsy was performed, and histopathological examination confirmed the diagnosis of DFSP.
• The patient was referred to a specialized center for rare skin malignancies.

Findings:

• Histopathological examination is the definitive diagnostic method for suspected DFSP.
• DFSP exhibits clinical heterogeneity, complicating initial diagnosis.
• Prompt and accurate diagnosis is crucial for effective management.

Implications:

• Timely diagnosis of DFSP is essential due to its aggressive nature and high recurrence potential.
• Radical excision is the preferred treatment modality for DFSP.
• Early detection and appropriate treatment can improve patient outcomes and reduce the risk of recurrence.
