SKIN CHANGES IN OLD AGE
•Typical changes: include atrophy, laxity, wrinkling, dryness, irregular pigmentation and sparse grey hair. •changes are brought about by: age-related alterations in structure and function of the skin
•cumulative effects of environmental insults, especially ultraviolet radiation
•cutaneous consequences of disease in other organ systems
![Page 3: By :Dr.Pawana Kayastha. SKIN CHANGES IN OLD AGE Typical changes: include atrophy, laxity, wrinkling, dryness, irregular pigmentation and sparse grey hair](https://reader033.vdocument.in/reader033/viewer/2022042703/56649f185503460f94c2f560/html5/thumbnails/3.jpg)
•Immunity: alterations in immune surveillance and antigen presentation, and reduced cutaneous vascular supply which lead to decreases in the inflammatory response, absorption and cutaneous clearance of topical medications.
•Consequences: these changes make the skin less durable, slower to heal, and more susceptible to damage and disease.

COMMON SKIN DISEASES IN OLD AGE
•Prevalence: about 40% of individuals over the age of 60 years have significant dermatological problems.
•Diseases: the most common in this age group are:
• skin cancers • leg ulcers, a major cause of morbidity in the
elderly • blistering disorders• herpes zoster (shingles) and post-
herpetic neuralgia

inflammatory skin diseases, e.g. asteatotic, gravitational and seborrhoeic eczema, psoriasis
lichen sclerosus et atrophicus scabies lymphoedema pruritus of old age drug-related rashes

THE CHANGING MOLE
Long standing pigmented spot.
The principal clinical concern is to distinguish correctly between benign pigmented lesions and melanoma.
The situation is complicated by the fact that any one of a number of changes in a pigmented lesion is highly sensitive as a marker of melanoma, specificity is low.

'IS IT CANCER, DOCTOR?'
ABCDE FEATURES OF MALIGNANT MELANOMA
Asymmetry Border irregular Colour irregular Diameter often greater than 0.5 cm Elevation irregular
(+ Loss of skin markings)

HISTORY Determine the precise nature of the
change. Is it due to the development of itch, inflammation, bleeding or ulceration, or does it relate to the colour, size, shape or surface of the lesion?
Subtle changes:plucking hair,shaving,irritants
Is the patient worried about change in one or many moles?
Positive family history of melanoma. Fewer than 10% of melanomas occur in individuals with a strong family history but in some of these families up to 50% of individuals may develop melanoma.

EXAMINATION Examine the pigmented lesion carefully. Look at the morphology of the
melanocytic naevi at other sites. magnifying glass or dermatoscope whether the lesion is a benign
melanocytic naevus or a malignant melanoma
Before trying to answer this, the clinician needs to exclude the possibility that it is another type of pigmented lesion: Lentigo (a benign proliferation of
melanocytes) Freckle (ephelis, a focal overproduction of
melanin,)

Seborrhoeic wart (basal cell papilloma, a benign keratinocyte tumour)
Dermatofibroma. This lightly pigmented firm dermal nodule is common on extremities in young adults. It feels larger than it looks. There is dimpling when the skin is squeezed on both sides (positive Fitzpatrick sign).
Pigmented basal cell carcinoma : This lesion is usually found on the face of the elderly and is slow-growing. It has a blue-brown hue with an opalescent look. There may be a rolled edge around an ulcer.
Subungual haematoma

MANAGEMENT Any changing lesion which is suspected of being
a malignant melanoma should be excised without delay, with a clear margin.
If there is even a low index of suspicion of a
malignant melanoma ,then the lesion should be reviewed 1 month and may be 3mths later.Continuing change demands excision.
If benign then reassurance but advised to report back without delay if the change and concern continue
If in doubt cut out and then check the histology

PRURITISAn unpleasant localized or generalized
sensation on the skin, mucus membranes or conjunctivae which the patient instinctively attempts to relieve by scratching or rubbing

LATERAL INHIBITION: “GATE THEORY” Scratching stimulates large fast-
conducting A-fibers adjacent to slow unmyelinated C fibers
A-fibers synapse with inhibitory interneurons and inhibit C-fibers
Scratching may either–stimulating ascending sensory pathway-inhibit itch at the spinal cord Or,may damage itch fibers directly
