Benign Phyllodes tumor with massive squamous metaplasia
Abstract
Phyllodes tumors are rare fibroepithelial
tumors of the breast accounting for less
than 0.5 percent of all breast neoplasms.
Majority of these tumors occur in women,
the median age at presentation is 42 to 45
years. They are classified by WHO into
benign, borderline and malignant categories.
Although squamous metaplasia is
more often encountered in phyllodes tumors
as compared to fibroadenomas, it is
usually focal and not extensive.We present
a case of benign phyllodes tumor with extensive
squamous metaplasia and keratin
filled cysts which has not been reported so
far.
