A Case of Angiocentric Lymphoma

ABSTRACT

Angiocentric lymphoma is a lymphoma like lesion which has been known as a lethal midline granuloma, lymphomatoid granulomatosis and polymorphic reticulosis. It involves predominantly lungs, and other extranodal sites such as upper respiratory tract, skin, kidneys, peripheral nervous system and CNS. The authors experienced a case of angiocentric lymphoma which was misdiagnosed as orbital cellulitis because there were persistent epiphora, erythematous swelling in dacryocyst area and diffuse edema in upper and lower eyelids which occurred after functional endoscopic sinus surgery. This case was diagnosised as angiocentric lymphoma through multiple tissue biopsies. This disease is rare, especially in orbit and eyelid. It leads to the destruction and inflammation of tissue. To avoid misdiagnosis to orbital cellulitis, accurate biopsy is needed with the interchange of clinical informations with pathologist. We report this case with the review of literatures.
