INTRODUCTION: In dark skin patients, hypopigmentation is the most disfiguring condition. Very few studies on hypochromic disorders have been conducted in specialized health centers. The present study is aimed to describe the etiologies of hypochromic patches in dermatological area, in Bamako. METHODS: We carried out a cross sectional study in the Dermatology Clinic of the "Centre National d'Appui à la lutte contre la Maladie (CNAM, Ex Institut Marchoux)". All acquired hypochromic patches (HP) were selected...

BACKGROUND: Pytiriasis versicolor is an infectious disease caused by several Malassezia species which has a tendency to become relapsing or chronic. OBJECTIVES: This study was conducted in an attempt to investigate the clinical course of pityriasis versicolor with regard to the number of relapses after a 12-month therapy and correlate this number with isolates of Malassezia species. MATERIAL AND METHODS: 102 patients with clinical and laboratory diagnosis of pityriasis versicolor were monitored for 12 months to investigate the number of relapsing episodes of the disease...

Lepromatous leprosy (LL) represents the highest infective and multibacillary form of leprosy. Clinical manifestations are consequent to the haematogenous spread of bacilli and include macules, plaques and nodules in a symmetric distribution or a diffuse infiltration of the skin. LL may mimic many different inflammatory and neoplastic skin diseases and in a small percentage of patients, skin manifestation may be atypical. This article reports the case of a South American child with LL presenting with symmetrically distributed hypopigmented macules previously misdiagnosed as pytiriasis alba, atopic dermatitis and pityriasis versicolor...

Skin surface lipid (SSL) film is a mixture of sebum and keratinocyte membrane lipids, protecting skin from environment. Its composition is unique for the high percentage of long chain fatty acids, and of the polyterpenoid squalene, absent in other human tissues, and in non-human Primates sebum. Here, the still incomplete body of information on SSL as mediators of external chemical, physical, and microbial signals and stressors is revised, focusing on the central event of the continuous oxidative modification induced by the metabolic activity of residential and pathological microbial flora, natural or iatrogenic UV irradiation, exposure to chemicals and cosmetics...

Langerhans cells histiocytosis (LCH) affecting the skin most commonly has clinical and histopathologic diagnostic features. We are reporting two examples of Langerhans cell (LC) hyperplasia recognized in the skin biopsies of two children initially interpreted as LCH. The first was an 8-year-old boy finally interpreted as having an atypical type of contact dermatitis, while the second, an 8-year-old girl, was assumed to have Pytiriasis lichenoides et varioliformis acuta. None showed evidences of scabies. Both presented spongiotic dermatitis with numerous CD1a+ cells...

The taxonomy of the genus Malassezia has been recently revised and enlarged to include seven distinct species. The aim of the study was to analyse the prevalence of these species in the cutaneous lesions of pityriasis versicolor and dermatitis seborrhoeica, as well as in the normal skin. Seventy-five patients with pityriasis versicolor, 75 of dermatitis seborrhoeica, and 150 samples of normal skin (75 from the forehead and 75 from the shoulders) were studied. A direct microscopy with KOH + Parker ink was carried out in the pityriasis versicolor and dermatitis seborrhoeica samples...

INTRODUCTION: Malassezia spp. yeasts are opportunistic and newly emergent diseases. One or more species have been isolated in association with dermatological pathology and systemic disease. Their pathological role has not been fully elucidated since Malassezia spp. are common in normal skin flora. OBJECTIVE: In the current study, a search was undertaken for genetic markers in the Malassezia spp. isolates that correlate with each type of dermatologic lesion. MATERIALS AND METHODS: A total of 103 strains of Malassezia spp were isolated from patients with pytiriasis versicolor, seborrheic dermatitis, seborrheic dermatitis HIV (+), and atopic dermatitis, as well as from healthy individuals...

In 3 cases of lymphomatoid papulosis with few ulceronecrotic lesions and 5 with the classic features of pytiriasis lichenoides acuta with necrotic lesions, a considerable part of the cellular component of the infiltrate of the lesions showed the morphologic and cytochemical characteristics of the cells described as immunoblasts. The authors consider that the lymphomatoid papulosis could represent an immunoblastic response to an unknown antigen.
