Introduction:The geriatric population is composed of persons over 65 years of age and very few studies are available on the dermatologic diseases in this group. This study was done to study the spectrum of cutaneous manifestations and prevalence of physiological and pathological changes in the skin of elderly people. Material and Methods: Two hundred consecutive patients aged more than 65 years of age attending the outpatient clinic or admitted as inpatients in the Department of Dermatology at Vydehi Institute of Medical Sciences and Research Centre were subjects for the study. A detailed history of cutaneous complaints, present and past medical ailments was taken. A complete general physical, systemic examination and dermatological examination was done and all findings were noted in a pre designed proforma. Skin changes observed due to ageing were classified as physiological and pathological. Findings were collated in a master chart and results analyzed. Results: Out of 200 patients studied, 71% were males and 29% were females. Pruritus was the single most common complaint elicited (44%). Among the physiological changes, xerosis was the commonest (93%). Among the pathological changes skin tumours, eczemas, infections were the common findings. Conclusions:The geriatric dermatoses are different in different populations as some of the skin changes seen in western skin and Indian skin are not identical.

Pilomatricoma (pilomatrixoma) or calcifying epithelioma of Malherbe, is a tumor with differentiation toward hair cells, particularly hair cortex cells. It frequently presents as a firm, deep-seated nodule that is covered by normal skin. Bullous pilomatricoma is an unusual clinical variant. Reports on bullous variant of pilomatricoma is sparse, and only 17 cases have been reported world-wide until date out of which only two cases are reported from India. We present a report of a 17-year-old female with a solitary reddish semi-transparent blister over her right upper arm since 3 months resembling a bouncy ball. Histopathology revealed tumor nests of basophilic cells and eosinophilic shadow cells, which are consistent with pilomatricoma.

A 51-year-old circumcised male presented with hard, thick, keratotic, nail-like covering of the skin of his glans penis of 2 year duration. Histology showed acanthosis, papillomatosis, and elongated rete ridges into the dermis suggestive of pseudoepitheliomatous, keratotic, and micaceous balanitis with features of cellular atypia. Partial penile amputation was done. There was no recurrence after 6 months of follow up.

Context:Diabetes mellitus is associated with many skin manifestations including vitiligo. Vitiligo occurs more commonly in Type 1 diabetes mellitus. A few recent studies have shown its increased occurrence in Type 2 diabetes mellitus.Aims:This study aims to study the prevalence of vitiligo in Type 2 diabetic patients and to compare the prevalence of vitiligo in age- and sex-matched group of nondiabetic population.Settings and Design:The present study was a hospital-based cross-sectional study conducted in the Department of Dermatology in a tertiary care hospital.Subjects and Methods:Six hundred consecutive consenting patients of Type 2 diabetes were included in the study group and age- and sex-matched controls were healthy nondiabetic adult volunteers attending the Department of Dermatology. Fasting and postprandial blood sugar levels were done. A complete history, physical examination, and wood's lamp examination to detect vitiligo were conducted. In all those with vitiligo, the type of vitiligo was noted.Statistical Analysis Used:Data were analyzed using SPSS software version 20.0. Comparison between the presence of vitiligo in cases and controls was done using Chi-square test with P = 0.05 for significance.Results:Vitiligo was seen in 12% of cases and 6% of control group which was statistically significant (P < 0.01). There was no significant difference between cases and controls with respect to type of vitiligo.Conclusions:Vitiligo can occur in Type 2 diabetics as seen in our study and few other recent studies. The exact pathogenesis is not very clear and needs further consideration.

Localized scleroderma (also called morphea) is a term encompassing a spectrum of sclerotic autoimmune diseases that primarily affect the skin, but might also involve underlying structures such as the fat, fascia, muscle, and bones. Morphea profundus presenting with atrophic lesions has rarely been reported in the literature. Here we report two cases of morphea profundus presenting with noninflammatory depressed plaques, without any significant skin induration, pigmentation or textural change. Histopathology was confirmatory for morphea profundus.
