This document discusses various skin conditions that are associated with diabetes, including: - Diabetic dermopathy (diabetic shin spots), characterized by oval, dull-red patches on the shins, forearms, and thighs that evolve into brownish scars. Microangiopathy and neuropathy are involved. - Diabetic rubeosis, a rosy reddening of the face and sometimes hands and feet seen in long-standing diabetes, attributed to decreased vascular tone or microangiopathy. - Necrobiosis lipoidica, possible diagnosis for a diabetic patient with rashes on shins that ulcerate and heal, featuring yellow atrophic centers and an erythematous border

2. Diabetic dermopathy (diabetic shin
spots)
❑This is the most common dermatosis associatedwith diabetes
mellitus.
❑Microangiopathy and neuropathy are involved .
❑Lesions are predominantly situated on the shins,forearms, thighs and
over bonyprominences.
❑The initial lesion is an oval, dull-red papule 0.5–1cm in diameter. It
evolves slowly,producing a superficial scale, leaving an atrophic
brownishscar.
❑The colour is due to haemosiderin in histiocytes near the vessels.

4. Q) Binkley spots are also known as?
1. Diabetic Dermopathy
2. Cutaneous sarcoidosis
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. Granuloma annulare
2. Necrobiosis lipoidica
3. Reactive perforating collagenosis
4. Rubeosis

7. • Nonscaling plaques with a
yellow atrophic center, surface
telangiectases, and an
erythematous or violaceous
border that may be raised.

8. Scleredema diabeticorum
• The condition is mainly seen
in overweightadults with
non-insulin- dependent
diabetes
• It is essentially permanent,
painless and causes no
morbidity.

9. Finger pebbles
• Thickening of the skin on the
dorsum of the hand

10. Skin tags
• Skin tags are small, soft,
pedunculated lesions occurring
on eyelids, neck and axillae,
often associated with obesity.

11. Eruptive xanthomas of the skin
• Eruptive xanthomas may
develop in diabetic patients
with hyperlipidaemia.
• The lesions slowly resolvewhen
the diabetes is properly
managed.

12. • Vitiligo • Lichen planus

13. Diabetic bullae
• Diabetic bullae are uncommon,
but believed to be a distinct
marker for diabetes .
• The location is the lower legs
and feet, occasionally hands and
fingers.

14. Reactive perforating collagenosis
• The cause is attributed to
diabetic microangiopathy and
lesions are due to minor injury
such as pressure orscratching

15. Insulin lipodystrophy
• Patients present with atrophic
plaques at the sites of insulin
injection.
• There is atrophy of the
subcutaneous fat.
