Granulation tissue

NEOPLASMS- Cancerous or
Benign
• Cell divides rapidly
(cancerous or benign)
• An abnormal mass of
tissue that results when
cells divide more than
they should or do not
die when they should.
• Neoplasms may be
benign (not cancer), or
malignant (cancer). Also
called tumor.
Hyperplasia
• Tissues enlarge because of a stimulus that irritates the
cells
• Instead of finding a benign or malignant tumor,
microscopic examination of a biopsy specimen will
sometimes detect a condition called "hyperplasia."
• Nonetheless, cell structure and the orderly arrangement
of cells within the tissue remain normal, and the process
of hyperplasia is potentially reversible.
• An example of hyperplasia is a callus that may form on
your hand when you first learn to swing a tennis racket
or a golf club.
