ABSTRACT
Pathologically involved ectopic breast tissue is not commonly encountered. There have been, however, intermittent reports of involvement of ectopic breast tissue by many of the same benign and malignant processes that occur in normally located breast tissue. This article records what, to our knowledge, is the first case of cystosarcoma phyllodes arising in ectopic breast tissue of the axillary regions and is the second reported case of three primary cystosarcoma phyllodes arising synchronously. A review of the available literature pertaining to ectopic breast tissue and multiple cystosarcoma phyllodes is also presented.

Diminishing right ocular visual acuity for three weeks in a 30 year old man was confirmed by examination. Bilateral scotomata and bitemporal hemiachromatopsia indicated a chiasmal lesion; reduced visual acuity and Marcus Gunn pupil of the right eye and left relative temporal hemianopia indicated asymmetric involvement. Erythrocytes in the CSF verified a suspected subarachnoid bleed; contrast-enhanced CAT scan demonstrated a suprasellar mass. A cystic, multiloculated, bluish mass distorted the right optic nerve, tract, and chiasm. A hematoma was evacuated and biopsy revealed a cavernous hemangioma of the right optic nerve. Post-operatively, visual acuity has recovered in the right eye but a left homonymous temporal hemianopia has developed.
