Late local recurrence of dermatofibrosarcoma protuberans in the skin of female breast

Dermatofibrosarcoma protuberans (DFSP) of the breast is exceptionally obscure and late local recurrence of this entity on this site is even more uncommon. We describe such a case in a 48-year-old woman, who at the age of 35 had a DFSP excised from her right breast. Thirteen years later, she developed an ovoid mass in her right breast over the postsurgical scar area. Wide local excision of the tumor with generous tissue margin was performed and microscopic and immunohistochemical findings established the diagnosis of recurrent DFSP. No further treatment was administered and she remains well 18 months later, without tumor recurrence. We report an exceptionally rare case of local recurrence of DFSP in the female breast and discuss in detail the diagnostic and therapeutic implications of this pathology

Pulmonary sarcoidosis simulating metastatic breast cancer

The clinical appearance and imaging findings of sarcoidosis and breast carcinoma may sometimes mimic one another, making the differential diagnosis between these two diseases difficult in some cases. A 69-year-old woman displayed an irregular shaped lesion in her left breast. Preoperative localization modalities detected a breast mass with malignant characters. The patient also was found to have pulmonary findings for metastatic disease on chest computed tomography. These features were proven upon biopsy to be consistent with sarcoidosis. The patient underwent breast surgery, adjuvant chemoradiotherapy and hormonal therapy, while corticosteroids were administered for pulmonary sarcoidosis. The patient is well 12 months later, without recurrence. An unfortunate consequence of the presence of both entities in the same patient is the risk of misguided differential diagnosis and incorrect therapeutic strategy. This patient shows the importance of confirming a clinical diagnosis of sarcoidosis with appropriate biopsies and histological examination, prior to initiation of breast cancer therapy
