We report a case of mycosis fungoides metastatic to the anterior orbit in
an 83-year-old woman. The patient had a history of several years' duration
of well-controlled primary mycosis fungoides with localized dermatologic
T-cell lymphomas, mainly on the lower extremities. She developed gradual
proptosis, hyperophthalmos, and vertical diplopia. Computed tomography
demonstrated a solid, extraconal mass in the right lower anterior orbit.
Biopsy revealed a gristly, yellowish, infiltrating mass at the level of the
inferior orbital septum. Pathologic examination revealed anaplastic T
lymphocytes with multiloculated, cerebriform nuclei that matched those of
the primary mycosis fungoides skin tumors. Mycosis fungoides rarely spreads
to the ocular and periocular structures, and this case was unique in that
it presented as a pure orbital lesion with sparing of the overlying lids
and adnexal structures.
