Dermatite perioral granulomatosa com acometimento extrafacial na infância: boa resposta terapêutica com uso de azitromicina oral / Granulomatous perioral dermatitis with extra-facial involvement in childhood: good therapeutic response with oral azithromycin

RESUMO Objetivo: Apresentar um caso de dermatite perioral granulomatosa (DPG) com acometimento extrafacial e resposta terapêutica satisfatória ao uso de macrolídeo oral por curto período. Descrição do caso: Escolar de nove anos, sexo feminino, com quadro exuberante de DPG com acometimento extrafacial. Durante o período de evolução, submeteu-se a múltiplas terapêuticas ineficazes, apresentando melhora significativa das lesões após o uso de azitromicina por cinco dias. Comentários: A DPG é uma afecção dermatológica inflamatória representada por erupções papuloeritematosas em região perioral, nasal e periorbitária, mais comum em crianças e adolescentes. Raramente estende-se à região genital, ao tronco e às extremidades, caracterizando o comprometimento extrafacial. De etiologia ainda desconhecida, parece apresentar correlação com uso de corticosteroides tópicos e outros agentes.

ABSTRACT Objective: To present a case of granulomatous perioral dermatitis (GPD) with extra-facial involvement and good response to short-term treatment with oral macrolide. Case description: A 9-year-old girl presented with exuberant GPD with extra-facial involvement. During follow-up, she received multiple ineffective therapies, but showed significant improvement of the lesions after the use of azithromycin for five days. Comments: GPD is an inflammatory dermatological condition represented by papulo-erythematous eruptions on perioral, nasal and periorbital regions, more prevalent in children and adolescents. It rarely extends to the genital region, trunk, and extremities, which characterizes its extra-facial manifestation. Its etiology is unknown, but it seems to have a correlation with the use of topical corticosteroids and other agents.

Clinical findings and outcomes for dogs with uveodermatologic syndrome.

OBJECTIVE To evaluate signalment, clinical signs, treatment, and factors affecting visual prognosis in dogs with uveodermatologic syndrome (UDS). DESIGN Retrospective case series and nested cohort study. ANIMALS 50 dogs (37 Akitas and 13 non-Akitas) with UDS evaluated at 4 ophthalmology practices. PROCEDURES Data were collected from the medical records regarding signalment, clinical signs, biopsy results, medications, adverse effects, vision and glaucoma status at initial and subsequent examinations, and duration of follow-up. Various factors were examined for associations with development of blindness or glaucoma following initial examination. RESULTS The most common ophthalmic signs included aqueous flare (n = 35 [70%]), iris abnormalities (29 [58%]), retinal detachment (23 [46%]), and choroidal depigmentation or chorioretinal infiltrates (10 [20%]). At initial examination, 36% (18/50) of dogs had glaucoma and 57% (26/46) were blind in both eyes. Twenty-five (50%) dogs had vision at their final visit, representing 78% of the 32 dogs that had vision at initial examination or regained vision during the follow-up period. In dogs that lost vision, median time to permanent blindness in both eyes was 13.5 months (range, 0.4 to 59 months) after initial examination. No significant associations with time to glaucoma or vision loss were identified for signalment variables, specific medications, or duration of clinical signs prior to initial examination. CONCLUSIONS AND CLINICAL RELEVANCE UDS commonly resulted in glaucoma, vision loss, or both in affected dogs. No evaluated factor was associated with visual prognosis; however, a subset of patients maintained vision through to the final recheck examination.

The emergence of mucormycosis as an important opportunistic fungal infection: five cases presenting to a tertiary referral center for mycology.

BACKGROUND: Mucormycosis, a rare opportunistic fungal infection, is re-emerging in importance with the increase in prevalence of immunosuppressive states, both as a result of therapy and disease. METHODS: We report five cases of mucormycosis diagnosed by the Dermatology Department and managed jointly with the Medical and Surgical Services of "Dr Manuel Gea Gonzalez" General Hospital in Mexico City, a tertiary referral center for mycology. We also review the current literature including recent advances in medical therapy. RESULTS: Four of the five cases were of the rhino-orbital-cerebral variant, commonly associated with significant mortality, and one of these patients died despite early diagnosis and aggressive management. The fifth case was primary cutaneous mucormycosis and this patient survived infection without relapse. Diabetic ketoacidosis predisposed to infection in four cases and the other was associated with advanced human immunodeficiency virus infection. Radiologic imaging was important in cases of facial involvement in order to evaluate the extent of disease and possible intracranial involvement. All cases were managed with systemic antifungals and surgical debridement, together with the treatment of predisposing factors. CONCLUSIONS: These cases illustrate the need for early clinical recognition and prompt therapy, as well as the requirement for tissue biopsy in order to demonstrate the characteristic morphologic features of this fungal agent in the absence of positive mycology culture results. This report also highlights that, although rhino-orbital-cerebral mucormycosis requires effective multidisciplinary management, the disease not uncommonly presents to dermatologists for diagnosis.

Eyelid dermatitis: a report of 215 patients.

Between April 2001 and October 2003, 215 persons presented with eyelid dermatitis for the first time. They ranged in age from 4 months to 95 years, with an average age of 49.6 years and a median age of 51 years. There were 173 females and 42 males. 165 of 215 had allergic contact dermatitis (ACD) and another 9 had protein contact dermatitis without relevant positive patch tests. Atopic eczema comprised 37 of 215 (17%), but 33 of 37 also had contact allergies. Seborrheic dermatitis, psoriasis or both were found in 35 (16%). Sources of ACD included personal care products in 54 (25%), including 12 with at least 1 positive patch test to cosmetic applicators and 12 sensitive to at least 1 botanical ingredient. Allergy to artificial nails and/or nail lacquer occurred in 18 of 215 (8%). 5 persons had rosacea or periorbital dermatitis, and 2 had dermatomyositis. Other causes included bacterial, fungal and viral infections, some of which were quite unusual. The evaluation of persons presenting with eyelid dermatitis remains a relatively complex but rewarding discipline.

Rosacea-like demodicidosis in an immunocompromised child.

Demodex folliculorum is a saprophytic mite of the human pilosebaceous unit. It is rarely found in children. It has been implicated in the development of follicular pityriasis, rosacea-like demodicidosis, pustular folliculitis, blepharitis, and granulomatous rosacea. We describe a 4-year-old boy who developed asymptomatic facial lesions that histologically corresponded to demodicidosis. He was in clinical remission of acute lymphoblastic leukemia and currently receiving maintenance chemotherapy. Exanthems related to D. folliculorum are rare in children. Most cases occur in immunocompromised patients and the clinical and histologic findings are diverse. A differential diagnosis should be established with rosacea and perioral dermatitis. The role of Demodex in the pathogenesis of these disorders is controversial. Immunosuppression might increase the number of mites, favoring an inflammatory reaction, or there could exist an impaired cutaneous immunologic response to the parasites.
