Keloid type of fibromatosis-like metaplastic carcinoma of the breast with transformation into biphasic tumour in recurrences and lymph node metastases.

摘要

Metaplastic carcinoma of the breast with fibroma-tosis-like pattern of growth is a recently described type of breast carcinoma.1 It was thought originally that such tumours exhibited a high risk of local recurrence but showed no tendency to distal spread. In the second published series following the original report, it was demonstrated that these tumours may occasionally metastasize distantly but not, as also shown in the first study, to the axillary lymph nodes.2 Morphologically, fibromatosis-like pattern of growth was the only observed pattern but in some cases a minor (<5%) glandular or squamoid component was also present.1'2 Histological features of recurrent tumours were similar to the initial one.
