Abstract
The entity commonly referred to as chondrolipoma is a rare and enigmatic breast lesion with unclear histogenesis and a complete lack of molecular characterization. It is uncertain whether it represents a hamartoma, choristoma, or a distinct neoplasm, including possibly a variant of mammary-type myofibroblastoma. We report two additional chondrolipomatous lesions of the breast. The lesions had varying histologic and immunohistochemical features similar to myofibroblastoma, including the loss of retinoblastoma (Rb) protein expression in one lesion. Molecular analysis by chromosomal microarray analysis performed on a second lesion did not demonstrate a loss of 13q14 or 16q typical of myofibroblastoma. Our findings further support the concept that at least a subset of breast lesions that historically have been classified as chondrolipoma are related to myofibroblastoma. However, the lack of myofibroblastoma-specific molecular alterations in one lesion suggests chondrolipomas may also have varying origins.

Abstract
Mammary myofibroblastoma is a rare benign tumor. It is mainly seen in older men and postmenopausal women. These tumors can be presented with a palpable mass or can be discovered incidentally on routine screening. A 76-year-old male presented with a palpable breast mass that was increasing in size. The patient underwent wide local excision with no postoperative complications. The pathology finding was consistent with myofibroblastoma. Myofibroblastoma is a rare tumor and should be considered one of the differential diagnoses in breast lumps.

Abstract
Chondroid lipoma is a rare benign lesion affecting the breast, in which the diagnosis of malignancy is difficult to be excluded during preoperative studies. In this respect, a correct histopathological diagnosis is mandatory in order to avoid overdiagnosis and subsequently overtreatment. In the present study, the case of a 61-year-old patient who self-referred for the development of a large tumor at the level of the left breast is reported. Biopsy raised the suspicion of a chondroid lipoma; thus, the patient was submitted to conservative surgery. The lesion was completely excised by performing a total mastectomy. The histopathological studies confirmed the presence of chondroid lipoma, with no signs of malignant transformation. At the 24-month follow-up interval no signs of recurrence were detected. In conclusion, although it may reach significant dimensions, giant chondroid lipoma of the breast is a benign lesion that may benefit from conservative treatment and does not recur.
