Periductal stromal sarcoma in a child: A case report

Introduction. Periductal stromal sarcoma is an extremely rare malignant fibroepithelial tumor of the breast which is characterized by its biphasic histology with benign ductal elements and a sarcomatous stroma made of spindle cells and lacking phyllodes architecture. Its therapeutic management is based on wide surgery with free margins. Adjuvant therapies are not needed. Periductal stromal sarcoma may evolve into a phyllodes tumor with time, as well as a specific soft-tissue sarcoma. To the best of our knowledge, this tumor has never been described in a child. Case presentation. A 14-year-old Arabic boy was presented to our hospital one year ago with a nodule of the right breast that was gradually increasing in size without signs of inflammation. The histological examination after lumpectomy revealed a periductal stromal sarcoma with free surgical margins. No adjuvant treatment was given. At 50 months of close follow-up, no recurrence was observed. Conclusion: Periductal stromal sarcoma in a child is a very rare disease which has the same indolent behavior as it does in adults. Therefore, close follow-up is required. © 2011 Masbah et al; licensee BioMed Central Ltd.
