Ultrasound Pattern of Cutis Verticis Gyrata.

Cutis verticis gyrata (CVG) is a cutaneous benign condition that usually presents symmetric or asymmetric convoluted folds and deep furrows in the scalp, which mimic the disposition of the cerebral sulci and gyri. This scalp deformation may be a worrying situation for the patients and their families. Clinically, its diagnosis may be challenging because it can mimic other cutaneous conditions. So far, the ultrasonographic pattern of CVG has not been reported. Thus, we aim to review the ultrasound findings of this entity. All patients (n = 14) presented zones with dermal and hypodermal thickening that corresponded with the elevated clinical zones, followed by folds with normal cutaneous thicknesses. There was undulation of the cutaneous layers in all cases. The scalp areas involved the frontal, parietal, and occipital regions bilaterally. The mean maximum dermal and hypodermal thicknesses and echogenicities and the color Doppler characteristics are provided. No significant dilation of the hair follicles was detected. In conclusion, CVG presents an ultrasonographic pattern that can support its diagnosis and follow-up. This can help its differential diagnosis with other scalp dermatologic conditions.

Scalp eschar and neck lymphadenopathy after tick bite in Argentina.

Scalp eschar and neck lymphadenopathy after a tick bite (SENLAT) is an emerging non-pathogen-specific syndrome characterized by scalp eschar and occipital and/or cervical lymph node enlargement following a tick bite. We report a case of SENLAT syndrome in an Argentinian patient after exposure to ticks during outdoor work in the Paraná River Delta region.

Juvenile xantogranuloma with íris involvement / Xantogranuloma juvenil com acometimento iriano

Abstract Herein we report a case of juvenile xantogranuloma, an inflammatory disease more commonly diagnosed during childhood and is characterized by cutaneous and ocular manifestations. Iris is the main target, presenting as local or diffuse yellowish lesions. Iris involvement may precipitate not only glaucoma but also amblyopia. Treatment is based on corticosteroids therapy, either local or systemic aiming disease control.

Resumo É relatado um caso raro de xantogranuloma juvenil, doença de natureza inflamatória diagnosticada mais frequentemente na infância, com manifestações cutâneas e oculares. A íris é o principal sítio extracutâneo da doença, apresentando-se como lesão amarelada, difusa ou localizada. O acometimento iriano pode acarretar surgimento de glaucoma, além de ambliopia. O manejo clínico da lesão ocular no presente caso foi baseado no necessidade no uso contínuo de corticoide tópico e sistêmico para estabilização da doença.

Black women's hair: the main scalp dermatoses and aesthetic practices in women of African ethnicity.

Afro-ethnic hair is different from Caucasian and Asian hair and has unique features. Ethnic hair is more prone to certain conditions or diseases. Such diseases are not only related to the fragile inner structure of the hair, but also to the cultural habits of hairstyles that often exert traction forces upon the pilosebaceous follicle. Women with African hair subject their hair to chemical treatments such as hair straightening and relaxing, and thus modify the structure of their hair shaft, making it more susceptible to damage. For this reason, hair complaints are common among black women and represent a diagnostic challenge to the dermatologist, requiring a thorough clinical examination of the hair and scalp, and a detailed medical history of the patient. The purpose of this review is to warn of the potential side effects and sequelae related to hairstyles and hair treatments used by black women, and to highlight the major diseases that affect this ethnicity.

Cutis verticis gyrata as a clinical manifestation of Touraine-Solente-Gole' syndrome (pachydermoperiostosis).

Cutis verticis gyrata is a descriptive term for a condition of the scalp consisting of deep grooves and convolutions that resemble the surface of the brain. We present a case of a 22-year-old man who presented with pain and swelling of both knees and hands. Enlarged wrists, ankles and feet were also noted, along with facial seborrhoea, thickening of the skin and deformity of the fingers. Physical examination of the scalp showed a cerebriform appearance with accentuating folds and deep furrows (cutis verticis gyrata), thickening in the face, frontal and parietal regions. Bone enlargement of the hands, knees, ankles and feet was also found. Secondary causes of pachydermoperiostosis were negative.

[Furuncles on the scalp after a trip to Brazil]. / Furunkulöse Hauterscheinungen nach Brasilienaufenthalt.

HISTORY AND CLINICAL FINDINGS: A 68-year-old woman suffered for six weeks from four skin eruptions on her head after returning from Brazil. The skin manifestations resembled furuncles, grew continually in size until they were about 2 cm in diameter and [corrected] she finally developed intermittent sharp pain on her head. On presentation she had a mild lymphadenopathy on her neck but no other systemic complaints. INVESTIGATIONS: Each skin eruption had a central porus with seropurulent discharge and on examination within the central opening a whitish, tender moving mass could be detected. TREATMENT, COURSE AND DIAGNOSIS: We cautiously infiltrated each skin eruption with lidocaine. Immediately after infiltration a whitish maggot appeared from each nodule and could be easily extracted with a forceps. The maggots were identified as Dermatobia hominis larvae. After extraction a local antiseptic dressing was applied and the wounds healed without complications. CONCLUSION: Dermatobia hominis is a common cause of myiasis in Central- and South-America and should be taken into account in furuncular skin eruptions of returning travelers. The typical appearance of the skin eruption with a central porus, seropurulent discharge and a whitish, tender moving mass within the nodule is quite characteristic for myiasis. The patients often have [corrected] intermittent sharp pain in the area of the affected skin and report continuing growth of the nodules and a sensation of slight movement within the skin eruption. Extraction is accomplished with a forceps after lidocaine infiltration, alternatively an occlusive dressing could be applied by means of which the larvae can be removed easily from the cavity.

Artificial hair fiber restoration in the treatment of scalp scars.

BACKGROUND: There is presently no treatment for scalp scars that is fully satisfactory. The modalities of treatment currently in use are surgery, hair transplantation, and micropigmentation. Scalp implantation with artificial hair fibers is used by some physicians as an adjunctive treatment. OBJECTIVE: The objective was to assess the utility of artificial hair fibers to treat scalp scars. METHODS: Data were collected by the principal author from 10 hair restoration practitioners who tested polyamide hair fiber (Biofibre CE 0373/TGA by Medicap Ltd., Carpi (MO), Italy) implantation for scalp scars. RESULTS: Artificial hair fiber implantation occurred between June 1996 and December 2000, and observations continued until December 2004. Data from 54 scars from 44 patients treated showed: (1) no complications in 49 scars (90.7%); (2) mild adverse outcomes in 4 scars (7.4%)-temporary superficial inflammation-infection that subsided following topical cortisone and local/systemic antibiotic treatment; and (3) moderately adverse outcomes in 1 scar (1.9%)-significant inflammation and generalized infection requiring removal of artificial implant to alleviate. Occasional minor skin reactions, sebum plugs, and hyperseborrhea were successfully controlled and well accepted by patients. Fiber fall rate was 20% on average per annum. CONCLUSION: Data show that polyamide hair fiber restoration can be considered an adjunctive treatment for scalp scars in selected cases.

Cutis verticis gyrata secondary to a cerebriform intradermal nevus.

We report the case of a 30-year-old black man with a large mass consisting of longitudinal parallel ridges and furrows on the left parietal region. A small, single, hyperpigmented macule was present at birth and gradually grew and extended over the years. Cutis verticis gyrata was suspected, and an investigation was performed to discharge the possibility of pachydermoperiostosis. However, results of biopsies obtained from 3 different lesional areas showed the same histopathologic features--deep-seated hair follicles and clusters of nevus cells concentrated in the dermis. Cerebriform intradermal nevus is a rare cause of cutis verticis gyrata. Early diagnosis is extremely important to prevent the development of malignant melanoma.

Alopecia difusa na mulher / Diffuse hair loss in women

Os autores realizaram estudo retrospectivo, a partir da análise do prontuário de 291 mulheres com diagnóstico de Alopecia Difusa, de um total de 3.103 pacientes do sexo feminino, atendidas em clínica privada, no período de janeiro a outubro de 1991. Foram analisados dados epidemiológicos e prováveis fatores associados. A incidência de alopecia na mulher foi maior na clínica privada (11,4%) do que no Serviço de Dermatologia do HEC (2,6%). A Alopecia Difusa ocorreu como forma clínica mais comum, tanto em consultório privado (84,1%) como no HEC (71,4%). A faixa etária predominante foi dos 21 aos 40 anos (73,6%). Das causas prováveis relacionadas as mais freqüentes foram: stress/depressäo 76(26.1%); drogas 37(12,7%); dieta 33(11,3%); hiperfluxo menstrual 27(9,3%); pós parto 27(9,3%); anemia 18(6,2%)

Relación entre dermatitis seborréica del cuero cabelludo y la composición metálica del agua / Relationship between seborrheic deratitis of the scalp and metallic composition of water

El uso de agua de mar destilada para bebida y aseo se ha impuesto en los buques pesqueros en los últimos 15 años. Se estudió la composición metálica del agua en 19 buques durante la faena en tres puntos del sistema de distribución (destiladora, bebederos y duchas). Se escogieron dos buques según los resultados obtenidos para comparar en sus tripulaciones la incidencia de dermatitis seborréica del cuero cabelludo con la de la tripulación de un buque que consume agua del puerto. Se encontró relación estadísticamente significativa entre la composición metálica del agua en las duchas y la presencia de la enfermedad. La salinidad resultó el factor más influyente. Se sugiere la implantación de un sistema de vigilancia periódica de la calidad del agua en los buques
