Oculoectodermal syndrome is a rare disease characterized by the association of aplasia cutis congenita, epibulbar dermoids, and other abnormalities. This report describes the twentieth case of the disease. We report a 4-year-old female child who presented with the classical features of the syndrome: aplasia cutis congenita and epibulbar dermoids. Our case expands the clinical spectrum of the disease to include: diffuse hyperpigmentation (some following the Blaschko´s lines); hypopigmented skin areas on the trunk; arachnoid cyst on the right fronto-parietal border; rounded left side of the hippocampus; and dermoid cyst underlying the bulb-medullary transition...

Erythema ab igne is a condition characterized by skin changes due to chronic exposure to moderate temperature. We describe a female patient with continuous use of a laptop computer on exposed legs for 6 months and consequent development of reticulated hyperpigmentation at the area. Histopathological examination revealed epidermal atrophy, collagen fragmentation, and vacuolar changes in the basal layer, among other signs. We consider this case to be a modern cause of erythema ab igne.

Livedoid vasculopathy (atrophie blanche) is a form of thrombotic vasculopathy. It is characterized by small ulcers that become crusted, and heal after several months to produce white atrophic scars. The most commonly affected sites are the lower legs, in particular the dorsum of the feet and ankles. To date, the dermoscopic features of livedoid vasculopathy have not been clearly described in the literature. In this observational study, we sought to evaluate the dermoscopic patterns of livedoid vasculopathy and determine whether the dermoscopic features are associated with certain histopathological characteristics...

Cutaneous larva migrans (CLM) is a parasitic infection most commonly found in tropical and subtropical areas. However, with the ease and increase of foreign travel to many countries around the world, the infection is not limited to these areas. CLM is an erythematous, serpiginous infection with skin eruption caused by percutaneous penetration of the larvae to the skin. In this report, a case diagnosed as imported CLM after an Amazon trip and treated with albendazole was presented. A 36 year-old male patient admitted to infectious diseases clinic with intense itching, erythematous, raised, streaklike serpiginious eruptionand some redness at bilateral foot especially at the right foot for about one week...

BACKGROUND: RA patients being treated with biologics are known to have an increased risk of infections. We recently demonstrated that both CTLA4 Ig and anti-TNF treatment aggravate systemic Staphylococcus aureus (S. aureus) infection in mice, but with distinct clinical manifestations. However, the effects of CTLA4 Ig and anti-TNF treatments on a local S. aureus infection (e.g., skin infection) might differ from their effects on a systemic infection. AIMS: The aim of this study was to examine the differential effects of anti-TNF versus CTLA4 Ig treatment on S...

AIM: Cutaneous involvement is an early manifestation of systemic sclerosis (SSc). Localized areas of 'salt and pepper skin' (S&P) may develop. We hypothesize that S&P skin occurs frequently in diffuse cutaneous (dc) SSc which can be used in its early diagnosis and may correlate with joint contractures. METHODS: Sixty-five patients were recruited for this study. The demographic profiles of SSc were ascertained from hospital records. These patients fulfilled the 2013 American College of Rheumatology/European League Against Rheumatism classification criteria...

BACKGROUND: Glaucoma is a leading cause of irreversible blindness worldwide and the second most common cause of blindness after cataracts. The primary treatment for glaucoma aims to lower intraocular pressure (IOP) with the use of topical medicines. Topical medication instillation techniques, such as eyelid closure and nasolacrimal occlusion when instilling drops, have been proposed as potential methods to increase ocular absorption and decrease systemic absorption of the drops. OBJECTIVES: To investigate the effectiveness of topical medication instillation techniques compared with usual care or another method of instillation of topical medication in the management of glaucoma or ocular hypertension...

Bioactive compounds from natural sources, due to their widely-recognized benefits, have been exploited as cosmeceutical ingredients. Among them, phenolic acids emerge with a very interesting potential. In this context, this review analyzes hydroxycinnamic acids and their derivatives as multifunctional ingredients for topical application, as well as the limitations associated with their use in cosmetic formulations. Hydroxycinnamic acids and their derivatives display antioxidant, anti-collagenase, anti-inflammatory, antimicrobial and anti-tyrosinase activities, as well as ultraviolet (UV) protective effects, suggesting that they can be exploited as anti-aging and anti-inflammatory agents, preservatives and hyperpigmentation-correcting ingredients...

The growing interest in skin lightening has recently renewed attention on the esthetic applications of Chinese herbal medicine. Although Scutellaria baicalensis Georgi is used for antipyretic and antiinflammatory purposes, its whitening effect remains unclear. This study reports three major findings: (1) S. baicalensis has a potent inhibitory effect on melanogenesis; (2) wogonin and its glycoside are the active components of S. baicalensis; and (3) O-methylated flavones from S. baicalensis, such as wogonin, inhibit intracellular melanosome transport...

The increasing melanin hyperpigmentation of dark skinned individuals was related to the high activity of melanocytes. Also smoking reactive the melanocytes to produce melanin. Gingival depigmentation is a periodontal plastic procedure which has been carried out by various techniques. A healthy 36-years-old female patient complained about unaesthetic gingiva and she had smoked over 17 years. Hyperpigmentation of gingiva observed on the labial surface of both maxilla and mandibula. Er,Cr:YSGG laser was used for depigmentation with wavelength of 2780nm, frequency of 20hz, and pulse energy between 0-300 Mj...

Recent studies have shown that plumbagin has anti-inflammatory, anti-allergic, antibacterial, and anti-cancer activities; however, it has not yet been shown whether plumbagin suppresses alpha-melanocyte stimulating hormone (α-MSH)-induced melanin synthesis to prevent hyperpigmentation. In this study, we demonstrated that plumbagin significantly suppresses α-MSH-stimulated melanin synthesis in B16F10 mouse melanoma cells. To understand the inhibitory mechanism of plumbagin on melanin synthesis, we performed cellular or cell-free tyrosinase activity assays and analyzed melanogenesis-related gene expression...

BACKGROUND: Cutaneous hyperchromias are disorders of skin pigmentation involving an increase of melanin production and its irregular accumulation in skin cells. It is known that the use of sunscreens helps to prevent changes in the skin pigmentation pattern, but the structural and morphological alterations that occur in the different types of hyperpigmentations need better elucidation. OBJECTIVE: To assess the influence of solar exposure and protection habits on the pattern of skin pigmentation using reflectance confocal microscopy (RCM)...

Tattoo, a Polynesian word meaning 'to mark', is a form of body modification done by inserting indelible ink into the dermis to change its pigmentation. Tattoos are done for social, cultural, and religious purposes. It has been in existence since the 18th century and was associated with sailors, lower class individuals, and criminals. However, since the late 20th century, tattooing has undergone a redefinition and shifted to an acceptable form of expression all over the world, including Nigeria, cutting across almost all age groups and socioeconomic class...

BACKGROUND: Melasma presents a significant challenge to laser surgeons. Aggressive treatments often result in rebound melasma or post-inflammatory pigmentary alteration. Recent reports suggest melasma pathogenesis may have a vascular component. Spectrocolorimetry can detect subtle or sub-clinical telangiectatic erythema within melasma lesions. For certain patients identified by spectrocolorimetry, effective melasma treatment may include vascular-targeted therapy together with pigment-specific treatment modalities...

Melasma is a human melanogenesis dysfunction that results in localized, chronic acquired hyperpigmentation of the skin. It has a significant impact on appearance, causing psychosocial and emotional distress, and reducing the quality of life of the affected patients. Tranexamic acid (TA) is a plasmin inhibitor used to prevent abnormal fibrinolysis to reduce blood loss and exerts its effect by reversibly blocking lysine binding sites on plasminogen molecules, thus inhibiting plasminogen activator (PA) from converting plasminogen to plasmin...
