nevus of ota is a condition wherein the typical pattern of the bluish black pigmentation is noticed along with the cutaneous distribution of the trigeminal nerve. this condition is most prevalent in japanese population but comparatively rare among indians. we report a case of 23-year-old female presented with unilateral pigmented areas over the skin of forehead, malar area, ear and periorbital ...

This study was conducted to examine morphometric and meristic characteristics alongside pigmentation patterns of bream larvae, Abramis brama orientalis, in four stages of larval development. Morphological characters including total length (TL), standard length (SL), notochord length (NL), head length (HL), head depth (HD), eye diameter (ED) and mouth width (MW) were examined from hatching time ...

Case: A 40–year-old woman referred to the dermatological clinic of Razi hospital with painful lesions on the axillae, between her breasts and intergluteal region since adolescence. The patient had been treated with a variety of antibiotics with only minimal improvement. The lesions reappeared with cessation of treatments. On cutaneous examination, multiple furuncle-like discharging nodules were...

Four patients with minocycline-induced cutaneous pigmentation were treated with the Q-switched ruby laser. The pigmentation resolved and there was no adverse effects.

Idiopathic eruptive macular pigmentation is a rare condition characterized by asymptomatic pigmented macules involving the neck, trunk, and proximal portions of the extremities. On histopathologic examination, there was increased pigmentation of the basal layer in otherwise normal epidermis and scattered melanophages in the papillary dermis. We report a case of a 26-year-old woman with idiopath...

A FORM of grouped pigmentation of the retina may occur in association with detached retina due to choroidal melano-sarcoma and, when present, is probably diagnostic of this disease. Grouped pigmentation of the retina also occurs as a congenital stationary condition. Two cases of the former and three of the latter are presented below. Evidence is given that both forms of pigmentation may be due ...

We report a case of an ocular burn injury from boiling water which resulted in conjunctival pigmentation, 1 week following injury. For cosmetic purposes, 2 sessions of argon laser photoablation were performed. One month after laser treatment, conjunctival pigmentation had been successfully removed and the patient was very satisfied with the results. Argon laser photoablation may be an effective...

Pigmentation of the skin, hair, and eyes varies both within and between human populations. Identifying the genes and alleles underlying this variation has been the goal of many candidate gene and several genome-wide association studies (GWAS). Most GWAS for pigmentary traits to date have been based on subjective phenotypes using categorical scales. But skin, hair, and eye pigmentation vary cont...

To study cutaneous pigmentation in a physiological context, we have previously developed a functional pigmented reconstructed skin model composed of a melanocyte-containing epidermis grown on a dermal equivalent comprising living fibroblasts. The present studies, using the same model, aimed to demonstrate that dermal fibroblasts influence skin pigmentation up to the macroscopic level. The proof...

The aim of the study was to show whether there is any influence of food, drink or drug intake on the formation of tooth discoloration. A total of 500 patients aged 15-25 years were examined to take part in the study. Of these, 60 patients were selected and divided into two groups of 30 patients each. Group 1 included patients with black pigmentation on vestibular/oral tooth surfaces. Group 2 in...
