Adenolipoma—Eccrine and Apocrine Variants With Evidence for a Hamartomatous Process

The document discussed a study of 11 cases of adenolipoma, confirming previous findings and adding new observations. The patients, aged around 53, included 6 men and 5 women. The study identified various types of lipomas, such as spindle cell lipomas and nevus lipomatosus, with eccrine and apocrine glandular components. These components were rare in lipogenic lesions, with only about 30 cases reported in the literature. The study suggested that these lesions might develop from peripheral adipose tissue of eccrine glands or that the glands are entrapped by adipose proliferation. The findings supported the concept of a hamartomatous process, particularly in a case with extensive glandular components, which had not been previously described.
