PURPOSE To report 2 unusual cases of fungal keratitis due to Fonsecaea pedrosoi. METHODS Two patients were diagnosed with Fonsecaea pedrosoi keratitis. Their files were reviewed for predisposing factors, clinical characteristics, microbiological study, treatment, and outcome. RESULTS Two consecutive patients presented with brownish pigmented corneal ulcers in their eyes after sustaining eye...

Dermatitis neglecta is a condition that results from inadequate frictional cleansing leading to accumulation of corneocytes, sebum and sweat ultimately resulting in hyper-pigmented patch or verrucous plaque. Recognizing this condition avoids unnecessary, aggressive diagnostic and therapeutic procedures. Here we report three cases of dermatitis neglecta in whom the dermatitis developed as a resu...

Background: Birthmarks are common reasons for parents’ concern.Some of them may need further investigation to find out theunderlying systemic disorders or their potential for malignanttransformation. The purpose of this study was to determine thefrequency of vascular and pigmented birthmarks in infants fromthe Northeast of Iran.Method: This descriptive study was conducted on 1000 healthyinfants...

An eccrine nevus is a rare hamartoma characterized by an increase in the number or size of eccrine glands. Eccrine nevi usually present as localized hyperhidrosis and are not associated with overlying skin abnormalities. However, among the cases that have been reported in the literature, some unique presentations of eccrine nevi have been demonstrated, including a pigmented patch, a depressed n...

Albinism in mammals is accompanied by specific morphological and functional alterations of the visual system. To understand their cellular basis we studied the physiological characteristics and transmembrane currents of pyramidal neurons in 350-microm-thick slices of visual cortex from pigmented and albino rats using whole-cell and gramicidin perforated patch-clamp recordings. The resting membr...

Nevus of Ota is a macular discoloration the face which most commonly found in Japanese and females are more affected than males. It first described by Tanino 1939, involves skin along distribution second division trigeminal nerve. Involvement palatal mucosa occurs rarely nevus Ota, it usually blends with oral typically irregular, undefined often present as mottled patch. We describe here case i...

BACKGROUND The fixed drug eruption is a common adverse drug reaction. Clear identification of the culprit drug is not always possible in the clinical setting, and oral rechallenge may induce new lesions or severe reactions. OBJECTIVES The main purpose of this study was to evaluate the diagnostic value of patch testing in establishing an aetiological diagnosis in fixed drug eruptions. METHOD...

Pigmented lesions with different histology can appear similar, making clinical diagnosis of malignant melanoma difficult. This paper describes a new computer-based approach which uses an optical model of the skin to interpret the colours occurring in a lesion in terms of lesion histology. Through the development of an optical image formation model of human skin it is shown that all normal skin ...
