Extramammary orbital myofibroblastoma: a rare orbital tumor.

07:00 EST 8th January 2020 | BioPortfolio

Summary of "Extramammary orbital myofibroblastoma: a rare orbital tumor."

Extra-mammary myofibroblastomas are rare benign mesenchymal neoplasms, histologically and immune-phenotypically identical to mammary myofibroblastomas. Histologically, they are characterized by the abundance of spindle cells in hyalinized collagenous stroma with positive expression of CD 34 and desmin. We present an extremely rare case of extra-mammary myofibroblastoma of the orbit in a 29-year - old male who presented with painless proptosis of the right eye, with a description of clinical, radiological, and histological findings.

Medical and Biotech [MESH] Definitions

A nonspecific tumor-like inflammatory lesion in the ORBIT of the eye. It is usually composed of mature LYMPHOCYTES; PLASMA CELLS; MACROPHAGES; LEUKOCYTES with varying degrees of FIBROSIS. Orbital pseudotumors are often associated with inflammation of the extraocular muscles (ORBITAL MYOSITIS) or inflammation of the lacrimal glands (DACRYOADENITIS).

Inflammation of the extraocular muscle of the eye. It is characterized by swelling which can lead to ischemia, fibrosis, or ORBITAL PSEUDOTUMOR.

Rounded objects made of coral, teflon, or alloplastic polymer and covered with sclera, and which are implanted in the orbit following enucleation. An artificial eye (EYE, ARTIFICIAL) is usually attached to the anterior of the orbital implant for cosmetic purposes.

A ready-made or custom-made prosthesis of glass or plastic shaped and colored to resemble the anterior portion of a normal eye and used for cosmetic reasons. It is attached to the anterior portion of an orbital implant (ORBITAL IMPLANTS) which is placed in the socket of an enucleated or eviscerated eye. (From Dorland, 28th ed)

The surgical removal of the eyeball leaving the eye muscles and remaining orbital contents intact.
