endophytic growth
Pronunciation: en-doh-FYE-tik
Tumor growth pattern extending inward toward the vitreous cavity. Critical for staging and treatment planning in retinoblastoma.
Full Definition
A growth pattern where tumors, particularly retinoblastoma, extend inward from the retina toward the vitreous cavity rather than outward toward the choroid. This endophytic pattern is distinguished from exophytic growth and affects prognosis, risk of vitreous seeding, and treatment approach. The term is essential for accurate pathological description and clinical documentation in ocular oncology reports.
Usage
Usage note: Always contrast with 'exophytic' when describing growth patterns. Hyphenate when used as compound modifier.
