2. Diabeticdermopathy(diabeticshin
spots)
❑This is the most common dermatosisassociatedwith diabetes
mellitus.
❑Microangiopathyand neuropathy are involved.
❑Lesions are predominantly situated on the shins,forearms,thighs and
over bonyprominences.
❑The initial lesion is an oval, dull-red papule 0.5–1 cm in diameter. It
evolves slowly, producing a superficial scale, leaving an atrophic
brownishscar.
❑The colouris due to haemosiderinin histiocytesnear the vessels.

4. Q) Binkley spots are also known as?
1.Diabetic Dermopathy
2.Cutaneoussarcoidosis
3.Lupus vulgaris
4.Rain drop pigmentation

5. Diabetic rubeosis
•A peculiar rosyreddening of
the face, and sometimes of
the hands and feet, may be
seen in long-standing
diabetes.
•The changes havebeen
attributed to decreased
vascular tone or diabetic
microangiopathy

6. Q) A 59 yr old lady, a known diabetic for the past 10 yr, presents
with rashes over shin that ulcerate and heal as shown in the
image. What is the possible diagnosis?
1.Granulomaannulare
2.Necrobiosislipoidica
3.Reactive perforating collagenosis
4.Rubeosis

7. •Nonscalingplaques with a
yellow atrophic center, surface
telangiectases, and an
erythematousor violaceous
border that may beraised.

8. Scleredemadiabeticorum

lesions are due to minor injury
such as pressure orscratching

15. Insulinlipodystrophy
•Patients present with atrophic
plaques at the sites of insulin
injection.
