This study provides important data on the frequency of dermatologic diseases in elderly patients, and shows variations in the frequency depending on age, gender, and season. We believe that this study will create awareness about the extent and patterns of dermatologic problems in geriatric patients.

Case 1 A 9‐year‐old girl applied a temporary henna tattoo to her right arm and 1 week later repeated the same process. In the following 2 days, erythema and papulovesicular eruptions developed at the application site (Fig. 1). Patch tests were performed with the European Standard Series, specific hairdressing agents, and commercial and natural henna. The patient showed a 3+ reaction to both natural henna and ‘‘para‐phenylenediamine (PPD)’' 1% and a 3+ reaction to nickel sulfate 5% at 48, 72, and 96 h (Fig. 2). She was treated with topical steroid cream (beclomethasone dipropionate), applied twice daily. A slight postinflammatory hypopigmentation was observed at the time of the patch test. The hypopigmentation has gradually decreased in severity over time (Fig. 3). 1 Case 1: temporary henna tattoo reaction with papulovesicular eruptions 2 Case 1: patch test results. (A) 3+ reaction to nickel sulfate 5%; (B) 3+ reaction to para‐phenylenediamine (PPD) 1%; (C) 3+ reaction to natural henna 3 Case 1: postinflammatory hypopigmentation Case 2 An 11‐year‐old boy was admitted to our outpatient clinic with itchy, erythematous, papulovesicular eruptions on the left arm. These lesions appeared after application of a temporary henna tattoo with a ‘‘do‐it‐yourself’' kit to the left arm. Patch tests were performed with the European Standard Series and commercial tattoo products. The patient showed only a 1+ reaction to commercial henna. He was treated with topical steroid cream (beclomethasone dipropionate), and 2 weeks later his lesions had totally disappeared. Case 3 A 12‐year‐old girl applied a temporary henna tattoo to her left arm. Several hours later, erythema, edema, and itching developed. Patch tests were performed as for Case 2. The patient showed a 2+ reaction to commercial henna. Topical steroid cream (beclomethasone dipropionate) was effective, and 3 weeks later the lesions had healed with slight hypopigmentation. The postinflammatory hypopigmentation traced the tattoo design exactly, which was in the form of a fish (Fig. 4). On follow‐up, the hypopigmentation was not permanent. 4 Case 3: fish‐shaped postinflammatory hypopigmentation

Punctate palmoplantar keratoderma (PPPK) is a rare entity with an estimated prevalence rate of about 1.17 per 100,000. The exact etiology of the disorder is not known but a dual influence of genetic and environmental factors may trigger the disease. We report the case of a 70-year-old male patient with punctate palmoplantar keratodermic lesions for more than 40 years. Histopathologic examination revealed a hyperkeratotic epidermis without columns of parakeratosis or elastorhexis. On electron microscopy, the basal cells of the epidermis were found to have enlarged nucleoli and abundant tonofilaments, with keratohyalin-like granules confined to the upper part of the stratum spinosum, findings that were consistent with PPPK. Topical keratolytic agents were used with little success. Patients with PPPK and their next of kin should be investigated for possible associated malignancies.

These results show a protective effect of EGCG when applied topically before UVA exposure. No benefit was detected when EGCG was applied after UV exposure.

Phenol used in partial matricectomy shows its effects by denaturing matrix proteins. This highly successful method has the major problem of oozing which can continue for 5-6 weeks. objective. The goal of this study was to determine the effect of 20% ferric chloride (FC) (FeCl 3 ) on minimizing the oozing after chemical matricectomy with phenol. methods. Sixty-seven patients with stage III onychocryptosis were treated by chemical matricectomy with 90% aqueous phenol. In 32 of these patients FC was applied to the nail bed after the phenolization procedure. results. We found a statistically significant ( P Ͻ .001) reduction of oozing in the FC-applied group of patients. conclusion. We think that using FC after phenol chemical matricectomy results in a significant reduction in oozing from the operation site.
