Abstract
Dendritic fibromyxolipoma (DFML) is a rare soft tissue tumor recently described with only 27 cases reported in the literature. None of them have shown recurrence or metastasis after excision. Histologically it is composed of small stellate or spindle cells in a myxoid stroma with abundant collagen bundles mixed with mature adipose tissue. The proliferating cells typically show immunoexpression positive for CD34 and bcl-2. A cytogenetic analysis reveals deletion involving 13q14.3 region. We describe the first reported case to date located in the infraclavicular region. A 69 year old male with a painless mass well circumscribed and 5 cm in size of several years of evolution, that after excision (2 years ago) he has not shown signs of recurrence or metastasis. This study reflects the clinicopathological features, differential diagnosis and a review of the literature of the DFML.
