Dendritic fibromyxolipoma of the male breast: case report and literary review

DFML is a benign lipomatous tumor with unique morphological features. Complete surgical excision typically leads to no recurrence. This report documents the first known instance of DFML in the mammary gland of a male patient. Furthermore, an analysis of 95 previously documented cases of DFML was conducted. It is strongly advocated that the World Health Organization reclassify DFML as a mucinous subtype of spindle cell lipoma. This reclassification would improve the understanding of DFML and help avoid unnecessary aggressive treatments due to misdiagnosis as a malignancy.
