Summary
Desmoplastic fibroblastoma, a rare benign tumor, typically affects subcutaneous tissue. This case highlights an unusual dermal presentation as a sacral mass in a young male, emphasizing diagnostic awareness.
Area of Science:
- Oncology
- Dermatopathology
- Soft Tissue Neoplasms
Background:
- Desmoplastic fibroblastoma, also known as collagenous fibroma, is a rare benign soft tissue tumor.
- Most commonly observed in subcutaneous tissue or skeletal muscle, dermal involvement is exceptionally rare.
Purpose of the Study:
- To report an unusual case of dermal desmoplastic fibroblastoma.
- To highlight the rare presentation of this benign neoplasm in the dermis.
- To increase awareness and aid in differentiating it from other soft tissue tumors.
Main Methods:
- Case report of a 16-year-old male with a large sacral mass.
- Histopathological examination of the dermal tumor.
- Review of relevant literature on desmoplastic fibroblastoma.
Main Results:
- Diagnosis of dermal desmoplastic fibroblastoma confirmed.
- The tumor presented as a large sacral mass, an atypical location for dermal involvement.
- Distinguished from other benign and malignant soft tissue neoplasms.
Conclusions:
- Dermal desmoplastic fibroblastoma is an exceedingly rare entity.
- Awareness of this rare presentation is crucial for accurate diagnosis.
- Essential for avoiding misclassification with other soft tissue neoplasms.
