Imaging • X-ray • Ultrasound • CT • MRI- T 1 • MRI- T 2 • PET • Scrintigraphy
What types of treatment are available? Radiation Steroid Injection Surgery cryosurgery 5 -fu interferon pressure devices
Keloid Case #1 • 22 Yr old male presents with keloid of the left buttock and an umbilical hypertrophy • Hx of Lipoma • Patient was treated with several attempts of surgical removal
Radiation Treatment Before Radiation After Radiation
Keloid Case #2 34 -year old female presents with recurrent keloid behind her left ear. Patient was treated in 5 fx’s to a total of 1500 c. Gy, 300 c. Gy/day with 6 Me. V and 1 cm bolus. A 6 x 6 cone was used. She has a hx of endometrial cancer and a family hx of ovarian cancer from her mother. The pt was positioned on her right side w/ a wedge behind her back for support and strapped to the PSA (for fear of heights). Her ear was taped and the bolus was placed on top.
Superficial Brachytherapy After Keloidectomy • 21 • 36 patients studied from 4/08 -4/09 histologically confirmed keloids were treated with HDR-SB • All pt’s had a keliodectomy • All patients of Asian ethnicity (18 -69) • Median age 41 • 16 female and 5 male
• • The keloids were located on the anterior chest wall, scapular, lower jaw, suprapubic area and other areas Ir-192 was used 20 Gy in 4 fx/day was used for the suprapubic, lower jaw, scapular and chest wall 15 Gy in 3 fx/day was used for all other lesions Only 2 pt had recurrance Of these 2 pt’s 1 had dysraphia No other patients had reactions other than erythema

Mangement cont… Before a procedure ask the patient if they have had problems with scarring in the past. • Have an informed consent discussing the risk and potential to scar or keloid. • Use pressure earrings for pierced ears • Top choices for tx are: • • Presssure tx • Steroid inj • Silicone sheeting
