Acné queloideo nucal y adherencia al tratamiento: a propósito de un caso y revisión del tema / Acne keloidalis nuchaeand adherence to the treatment: A proposal of a case and review

Resumen El acné queloide nucal es una forma crónica de foliculitis cicatricial, caracterizada por el desarrollo de papulo-pústulas que se convierten en queloides cuyo proceso fisiopatológico no está bien dilucidado. Se presenta un paciente de 19 años, con antecedente familiar de acné queloideo nucal, cuya aparición es posterior al ingreso de una bacteria en el cuero cabelludo. El caso se reporta por la rara frecuencia de la enfermedad y como conocimiento de una posible activación de la enfermedad por el ingreso de una bacteria al organismo del paciente. En este caso, se realiza una revisión breve del tema y resalta la exacerbación del proceso inflamatorio y empeoramiento de la enfermedad con medicina alternativa usada deliberadamente por familiares del paciente.

Abstract Keloid acne nuchae is a chronic form of cicatricial folliculitis, characterized by the development of papules, pustules, and keloid-like plaques which pathophysiological process is not well elucidated. We report a 19-year-old patient, with a family backgroundof keloid acne nuchae, whose appearance is after the entry of a bacterium into the scalp. The case is also reported due to the rare frequency of the disease and as knowledge of a possible activation of the disease by the entry of a bacterium into the patient's organism. In this case, a brief review of the subject is made and the exacerbation of the inflammatory process and worsening of the disease with alternative medicine deliberately used by the patient's relatives is emphasized.

Folliculitis decalvans: a case report of satisfactory recovery after implementing

ABSTRACT Introduction: Folliculitis decalvans is a rare skin disease characterized by the presence of painful papules and pustules with an underlying neutrophilic infiltrate, usually on the scalp. Its treatment is lengthy and challenging, and recurrence is relatively common. Although its etiology is unknown, several theories explaining its development have been proposed, including colonization by Staphylococcus aureus. Case description: This is the case of a 26-year-old male healthcare worker who visited the outpatient service after experiencing a 4-year history of painful pustules on the scalp; initially these lesions were located in the occipital region, but then also started to appear in the temporal and parietal regions. After being treated for bacterial folliculitis and having several recurrences, a skin biopsy was performed, which allowed diagnosing him with folliculitis decalvans. Once the diagnosis was made, isotretinoin (20mg) treatment was implemented for a year and a half, achieving complete remission of the lesions. Conclusion: Although this case has some limitations, such as the lack of histopathology images and some control laboratory tests, it clearly shows the difficulties faced when treating this type of skin disorders and presents an overview of the use of isotretinoin, evidencing that although this drug is well tolerated, possible adverse reactions from drug interactions with trimethoprim/sulfamethoxazole may arise. In addition, this case is of great importance since the possible presence of a familial cluster of folliculitis decalvans could be confirmed, if further genetic testing is performed.

RESUMEN Introducción. La folliculitis decalvans es una enfermedad dermatológica rara caracterizada por la presencia de pápulas y pústulas dolorosas que están acompañadas de un infiltrado de neutrófilos subyacente. Esta condición suele aparecer en el cuero cabelludo, su recurrencia es relativamente común y su tratamiento, largo y difícil. Aunque su etiología es desconocida, se han propuesto muchas teorías que intentan explicar su aparición, siendo la colonización por Staphylococcus aureus una de ellas. Presentación del caso. Hombre de 26 años que se desempeñaba como trabajador de la salud y consultó por un cuadro clínico de 4 años de evolución caracterizado por la aparición de pústulas dolorosas en la región occipital, las cuales posteriormente se extendieron a la región temporal y parietal. Después de tratarlo como una foliculitis infecciosa y tras múltiples recurrencias, se realizó una biopsia de las lesiones que permitió diagnosticarlo con folliculitis decalvans. Se instauró un tratamiento consistente de 20mg de isotretinoina al día por un año y medio, con el cual se logró la resolución de la folicutis. Sin embargo, dos años después tuvo un relapso, pero, según el paciente, esto pudo ocurrir por el consumo de derivados lácteos, ya que, según indicó, cuando suspende el consumo de esta clase de productos no aparecen más lesiones luego de 2-3 semanas. Conclusión. Aunque este caso tiene algunas limitaciones como la ausencia de imágenes histopatológicas y algunos laboratorios de control, muestra las dificultades para tratar este tipo de condiciones dermatológicas y presenta un panorama del uso de la isotretinoina, ya que evidencia que este medicamento tiene una buena tolerancia, pero presenta interacciones medicamentosas adversas con la trimetoprima/sulfametoxazol. Además, este caso es de gran importancia, ya que, si se realizan más pruebas genéticas, podría confirmarse la posible presencia de un grupo familiar de foliculitis decalvante.

Foliculitis pseudolinfomatosa de McNutt (localización nasal) / McNutt's pseudolymphomatous folliculitis (nasal located)

La foliculitis pseudolinfomatosa, descripta por McNutt en 1986, es una afección de etiología desconocida y poco frecuente, que simula un linfoma cutáneo tanto por su clínica como por su histología. Se presenta como una lesión nodular solitaria, eritematosa, de 0,5 hasta 3cm, de crecimiento rápido, sobre todo en la cara, en personas de 40 a 60 años, con una histopatología caracterizada por un infiltrado linfocitario B yT perifocular, y células dendríticas positivas en la inmunohistoquímica para S100yCD1a. Su curso es benigno, muchas veces autolimitado. Se expone el caso de una paciente con una particular forma clínica de pseudolinforma.

Pseudolymphomatous folliculitis, described by McNutt in 1986, is a non-frequent entity of unknown etiology that simulates a cutaneous lymphoma, both clinically and histologically. It shows as a solitary erythematous nodular lesion of 0.5 to 3 cm, with a rapid growth, mainly on the face, in people aged 40 to 60 years, and histopathology characterized by a perifollicular B and T lymphocytic infiltrate, and positive dendritic cells for immunohistochemistry S100 and CD1a. Its course is benign, often self-limited. The case of a patient with a particular clinical form of pseudolymphoma is presented.

Enfrentamiento de las infecciones de piel en el adulto / Managing adult skin infections

En la actualidad, las infecciones de piel y partes blandas forman parte de un alto porcentaje de las consultas en salud. Estas van desde infecciones leves, donde el manejo se realiza con tratamiento tópico, hasta aquellas con severo compromiso sistémico, requiriendo terapia antibiótica sistémica e incluso el desbridaje quirúrgico. En general, son producto de un desbalance entre los mecanismos de defensa de la barrera cutánea y los factores de virulencia y patogenicidad de los microorganismos que la afectan. Se pueden clasificar según distintos criterios, como por ejemplo, profundidad, gravedad, microorganismos involucrados y si estas son purulentas o no. El reconocer estas entidades clínicas es de suma importancia para llevar a cabo un adecuado tratamiento en los pacientes que presentan estas afecciones, ya que los diagnósticos erróneos llevan a las múltiples consultas con el consiguiente aumento de costos asociados en atención en salud.

Currently, skin and soft tissue infections are part of a high percentage of health consultations. These range from mild infections, where management is performed with topical treatment, to those with severe systemic compromise requiring systemic antibiotic therapy and even surgical debridement. In general, they are the product of an imbalance between the defense mechanisms of the skin barrier and the virulence and pathogenicity factors of the microorganisms that affect it, which can vary from bacterial, viral, fungal and parasites agents. Skin and soft tissue infections can be classified according to different criteria, such as depth, severity, microorganisms involved and whether they are purulent or not. Recognizing these clinical entities is of utmost importance to carry out adequate treatment in patients with these conditions, since erroneous diagnoses lead to multiple consultations with the consequent increase in costs associated with health care

Celulitis disecante del cuero cabelludo a propósito de un caso clínico / Dissecting cellulitis of the scalp a clinical case report

Celulitis disecante del cuero cabelludo (CDC) es una enfermedad inflamatoria crónica neutrofilica, clasificada dentro las alopecias cicatriciales, su etiopatogenia es desconocida, se manifiesta por nódulos en el cuero cabelludo de predominio en región occipital y vértice, si es muy extensa puede confluir y formar fistulas, predomina en descendientes afroamericanos, es de difícil tratamiento.

Dissecting cellulitis of the scalp (DCS) is a chronic inflammatory primary neutrophilic scarring alopecia, and its etiopathogenesis is yet only partly understood. DCS manifests with inflammatory nodules on the occipital scalp or vertex that may evolve to extensive confluent boggy plaques with sinus tract formation¹. predominantly affects young Afro-descendent men.Therapeutic management of DCS is often challenging1,6.

An update on pityrosporum folliculitis in Singapore from a single tertiary care dermatological centre

INTRODUCTION@#Pityrosporum folliculitis (PF) is a common skin condition that can be easily misdiagnosed, especially by non-dermatologists. While the initial diagnosis is often made clinically, skin microscopy may help to confirm the same. However, there is scant literature regarding the clinical epidemiology of PF. To our knowledge, in Singapore, only one prior epidemiological study was performed in 1987. Through the present study, we aimed to provide an update regarding the epidemiology, diagnosis and treatment of patients with PF in Singapore.@*METHODS@#We performed a retrospective review of patients with clinical presentations compatible with PF who presented to the dermatology clinic at the National University Hospital, Singapore, between 1 January 2011 and 31 December 2015. The medical records of patients identified as having clinical presentations that resembled PF were reviewed via written and electronic databases. Information regarding the demographics and clinical presentation of the patients was collected.@*RESULTS@#Of the 375 patients identified, 214 (57.1%) were confirmed as having PF based on Gram-stain microscopy. Most (35.0%) of these 214 patients were aged between 21 and 30 years, with a male-to-female ratio of 3:1. The lesions predominantly occurred on the trunk and the back. The majority of patients presented with symptoms that lasted more than one month. 128 (59.8%) patients received oral antifungal treatment, whereas 82 (38.3%) patients were treated with topical antifungal treatment alone.@*CONCLUSION@#A typical Singapore patient with PF is a young man aged 21-30 years, with erythematous follicular papules or pustules over the trunk and the back.

Trichoscopic stages of dissecting cellulitis: a potential complementary tool to clinical assessment

Abstract Dissecting cellulitis is a chronic, progressive, and relapsing inflammatory disease that predominantly affects the vertex and occiput of young Afro-descendent men. It starts with papules and pustules that evolve to nodules, abscesses, and cicatricial alopecia. This article illustrates the evolutive trichoscopy of dissecting cellulitis, from its early phase, through the abscess phase, to the fibrotic cicatricial phase. Trichoscopy complements clinical-pathological classification, representing a complementary tool useful in early diagnosis and monitoring of the patient during treatment.

Trichoscopy findings in dissecting cellulitis

Abstract Dissecting cellulitis is an inflammatory, chronic, and recurrent disease of the hair follicles that mainly affects young Afro-descendent men. Trichoscopy is a method of great diagnostic value for disorders of the scalp. Clinical and trichoscopic findings of dissecting cellulitis are heterogeneous and may present features common to non-cicatricial and scarring alopecia. This article presents the trichoscopic findings of dissecting cellulitis that help in the diagnosis and consequent institution of the appropriate therapy and better prognosis of the disease.

Foliculitis decalvante y disecante. reporte de cuatro casos clínicos / Folliculitis decalvans and dissecting folliculitis.report of four clinics cases

RESUMEN Las alopecias cicatrizales comprenden un grupo heterogéneo de trastornos, que dan lugar a la pérdida permanente del pelo. Se distinguen las alopecias primarias, en las que el folículo piloso es el blanco específico del proceso destructor y las alopecias secundarias, que son el resultado de una destrucción no específica. Dentro del primer grupo se encuentran, las denominadas alopecias del tipo neutrofílicas, entre ellas:las foliculitisdecalvante y foliculitisdisecante o perifoliculitiscapitisabscedens et suffodiens. Se presentan a continuación, cuatro casos clínicos, tres con diagnóstico de foliculitisdecalvante y uno con foliculitisdisecante, en pacientes de sexo masculino, en edades comprendidas entre 21-39 años, con un retardo en el diagnóstico clínico-patológico entre 8 y 36 meses. Dos de ellos, obtuvieron una buena respuesta al tratamiento con isotretinoína vía oral, mientras que dos no regresaron a la consulta, por lo que se desconoce su evolución. Motiva este reporte,destacar la importancia de comunicar la necesidad deun diagnóstico precoz, con la finalidad de ofrecerles a los pacientes una respuesta terapéutica satisfactoria.

SUMMARY The cicatricialalopeciasinclude a heterogeneous group of disorders that lead to permanent hair loss. Primary alopecias are distinguished, in which the hair follicle is the specific target of the destructive process, and secondary alopecias, that are the result of a non-specific destruction. Within the first group are the so-called neutrophilic type alopecias, consisting of the folliculitis decalvans and dissecting folliculitis or perifolliculitis capitis abscedens et suffodiens. Four clinical cases are presented below, three of them being diagnosed with folliculitis decalvans and one with dissecting folliculitis, in male patients, aged between 21-39 years, having a delay in clinical-pathological diagnosis between 8 and 36 months. Among these, two obtained a good response to treatment with isotretinoin orally, while the other pair did not return to the consultation, so their evolution is unknown.This report motivates the need for an early diagnosis in order to offer patients a satisfactory therapeutic response, which does not occur in later stages.

Profile of skin diseases in a community of fishermen in the northern coast of the state of São Paulo: the expected and the unusual

Abstract: Background: The fishing colony of the Picinguaba neighborhood is located at the northern end of the coast of the state of São Paulo. It has about 300 residents, of which approximately 100 are professional fishermen. Objectives: This study aimed to identify the main dermatoses of the community in comparison with other populations, and their frequency. Methods: The dermatoses were identified and tabulated for two years, in a prospective study carried out on monthly trips to the fishermen's colony in Picinguaba. Results: One hundred and eighteen patients were attended and followed up, which is equivalent to about 1/3 of the colony's inhabitants. Of these, 43 were children (under the age of 14) and 75 were adolescents and adults. The diseases observed were catalogued according to the age groups. Although most dermatoses in the community were similar with those observed in the general population, some specific cases could be seen, such as folliculitis on the legs of fishermen and an unexpected low frequency of actinic lesions in the colony, as well as dermatitis by aquatic animals. Study Limitations: The limitations were monthly attendance and the spontaneous demand of the patients. Conclusions: The finding of community-specific dermatoses and the low incidence of malignant and pre-malignant tumors associated with sun exposure needs further studies for better clarification.

Versatile Scalp Donor Split Thickness Skin Graft in Burn Patients

PURPOSE: It is well known the advantages of scalp donor split thickness skin graft(STSG) in deep burn wound because of its scarless donor healing, and good color match in face. Inspite of the advantages of scalp as a skin donor site during split thickness skin graft some authors report the frequent postoperative folliculitis, and partial alopecia on scalp donor site. We had experienced 21 burn patients, who had full thickness skin defects caused by burn injuries, were successfully managed with scalp donor split thickness skin graft with our optimal donor management protocols. METHODS: We had 21 deep burn patients, who were managed with thin STSG from scalp donor for coverage of full thickness skin defects. The operative techniques of the harvesting scalp STSG, and scalp donor dressing care are such as followings. After the infiltration of the donor scalp area with 1:1,000,000 epinephrine diluted with saline, then usually 0.012~0.015 inch thickness skin were harvested with air driven Zimmer® dermatome. On postoperative 6days, the one layer of adhered Vaseline gauze at donor scalp site was manually removed, and the entire scalp was cleansed with water. After then the daily hair washing was continued to remove the desiccated scaly crust with thick exudate at the growing hair and follicle. RESULTS: The scalp split thickness skin graft at the recipient sites in 21 burn patients were survived completely. Ranges of patient's age were 8 months to 56. The size ranges of scalp STSG were 2×2 cm~12×15 cm. The grafted scalp donor STSG were survived in all cases. The mean epithelialization period of scalp donor was 7.2 days. The one case of transient folliculitis (5%) from the postoperative 8days was occurred, and it was disappeared slowly with vigorous daily hair washing, antiseptics and systemic antibiotics. In all cases, there was no micro-alopecia or alopecia, and scars in scalp donor after follow ups. The donor site pain was markedly disappeared within 1~2 postoperative day. The hemorrhage from the scalp donor site during operation was not noticeable. The newly growing hair at the scalp donor was noted from the 3 postoperative days by palpation or unaided eye through the Vaseline gauze dressing. The average lengths of newly growing hair shaft are 2~3 mm in postoperative 8 days, 5~6 mm in postoperative 14 days. CONCLUSION: We had successful reconstruction of postburn skin defects using scalp donor split thickness skin graft without donor scars, persistent folliculitis or alopecia on scalp donor. From the postoperative 6~7 days after harvesting the scalp donor STSG, early vigorous daily washing with water and open dressing of scalp donor site should be recommended in order to prevent folliculitis. After long-term follow ups, the scalp split skin grafted recipient sites showed reliable, and relatively good color match with surrounding skin in face and dorsum of hand.

Radical resection and local coverage of hidradenitis suppurativa - acne inversa: analysis of results / Tratamento cirúrgico de hidradenite supurativa - acne inversa: ressecção radical e cobertura local - análise de resultados

ABSTRACT Objective: to evaluate the primary outcome of local complications and late recurrence in patients with hidradenitis suppurativa undergoing radical resection and specific reconstruction. Methods: we conducted a retrospective analysis of the medical records of patients attended by the Plastic Surgery Service of the Clinics Hospital, Medical School, USP, between 2010 and 2016. We included patients who underwent radical resection of hidradenitis suppurativa in advanced stage and reconstruction through primary closure, grafts or flaps. Results: we analyzed 34 lesions in 19 patients, of which 64.5% had local complications, though with 73.5% efficient healing after 12 weeks postoperatively. We observed late recurrence in 47%, but in isolation, 22.2% of the reconstructions with locoregional flaps had recurrence after one year. Conclusion: extensive and radical resection of the disease associated with locoregional flap coverage (pedicled or perforating) has been shown to be the best management in terms of late results.

RESUMO Objetivo: avaliar o desfecho primário de complicações locais e de recidiva tardia em pacientes com diagnóstico de hidradenite supurativa submetidos à ressecção radical e reconstrução específica. Métodos: análise retrospectiva baseada nos prontuários dos pacientes atendidos pelo serviço universitário de Cirurgia Plástica do Hospital das Clínicas da Faculdade de Medicina da USP, entre 2010 a 2016. Foram incluídos apenas pacientes submetidos à ressecções radicais de hidradenite supurativa em grau avançado, submetidos à reconstrução através de fechamento primário, enxertos ou retalhos. Resultados: foram analisadas 34 lesões, das quais 64,5% apresentaram complicações locais, porém com 73,5% de cicatrização eficiente após 12 semanas de pós-operatório. Recidiva tardia foi observada em 47%, porém, isoladamente, 22,2% das lesões reconstruídas com retalhos locorregionais apresentaram recidiva tardia após um ano. Conclusão: a estratégia de ressecção ampla e radical da doença associada à cobertura da ferida com retalho locorregional (pediculado ou perfurante) demonstrou ser o melhor manejo em termos de resultados tardios.

Granuloma de Majocchi: una forma de infección dermatofítica invasiva / Majocchi granuloma: a form of invasive dermatophyte infection

Resumen El granuloma de Majocchi es una forma de infección atípica por dermatofitos con invasión de la dermis y el tejido celular subcutáneo, favorecida por el trauma de los folículos pilosos o la inmunosupresión del huésped. Siendo una infección poco común, se destaca en este artículo el caso de una paciente que luego de usar esteroides tópicos presentó pápulas y pústulas en vulva, sitio inusual de granuloma de Majocchi, siendo este el cuarto reporte a nivel mundial.

Abstract Majocchi granuloma is a form of atypical infection by dermatophytes with invasion of the dermis and subcutaneous tissue, favored by the trauma of hair follicles or host immunosuppression. Being a rare infection, in this article highlights the case of a patient with papules and pustules on the vulva after using topical steroids, unusual site Majocchi granuloma, which is the fourth global report.

Red nodule on the face with "spontaneous" regression

Abstract Pseudolymphomatous folliculitis is a rare entity included among the cutaneous pseudolymphomas. A 32-year-old man, with an unremarkable medical history, presented with a two-month history of an asymptomatic solitary nodule on his left cheek. Histopathological examination demonstrated a dense nodular and diffuse dermal lymphocytic infiltrate with numerous histiocytes and dendritic cells that surrounded hypertrophic hair follicles. Pseudolymphomatous folliculitis commonly presents in the fourth decade of life, with no sex predominance, as an asymptomatic, rapidly growing and solitary red dome-shaped nodule on the face. It has a benign clinical course as the lesions usually resolve with surgical excision or regress spontaneously after incisional biopsy. Although there is no report of pseudolymphomatous folliculitis progressing into lymphoma in the literature, follow-up of these patients is recommended.

Foliculitis decalvante: caso clínico y revisión de la literatura / Folliculitis decalvans: clinical case and review of the literature

La Foliculitis decalvante (FD) es un tipo de alopecia cicatricial poco frecuente, cuya presentación clínica se caracteriza por la presencia en el cuero cabelludo de pápulo-pústulas foliculares, habitualmente dolorosas, asociado a lesiones nodulares que evolucionan hacia áreas redondeadas de alopecia cicatricial, irregulares y atróficas. Su sospecha diagnóstica se basa en los hallazgos clínicos mencionados, siendo confirmada con biopsia de cuero cabelludo. A la fecha no existe un tratamiento estándar establecido, existiendo diversas alternativas terapéuticas con resultados variables. A continuación se presenta el caso clínico de una mujer de 42 años, que consultó en policlínico de Dermatología por cuadro de alopecia de larga data, sin controles previos. Al examen físico destacó la presencia de pústulas foliculares en cuero cabelludo y alopecia cicatricial irregular y atrófica. Marcadores inmunológicos negativos. Se realizó una biopsia del cuero cabelludo, obteniendo hallazgos que confirman diagnóstico de FD. Se inició manejo con corticoides intralesionales, con mala respuesta. Posteriormente se realizó tratamiento con terapia fotodinámica, doxiciclina e isotretinoína evolucionando con buena respuesta clínica.

Folliculitis decalvans is an infrequent scarring alopecia characterized by the appearance on the scalp of, usually painful, follicular pustules associated with nodular lesions which leave irregular, round, scarring, atrophic areas of alopecia. Diagnosis is based on clinical findings and is confirmed by biopsy of the scalp. There is no standard treatment and therapeutic alternatives have variable results. We present the case of a 42 year old woman seen in a dermatology outpatients clinic for long term alopecia for which she had not previously consulted. The physical examination revealed follicular pustules on her scalp and irregular scarring atrophic alopecia. Immunological markers were negative. A biopsy of her scalp confirmed the diagnosis of FD. She responded poorly to intra-lesion corticoids. She then responded well to photodynamic therapy, doxycycline and isotretinoin.

A Case of Tinea Incognito Mimicking Folliculitis in Atopic Dermatitis Patient / 대한의진균학회지

A 27-year-old male with underlying history of atopic dermatitis presented with skin lesion on the trunk and upper extremity, occurring a month ago. Scattered erythematous multiple tiny maculopapules and patches were noticed. The lesion was first diagnosed as aggravated atopic dermatitis with folliculitis based on the clinical manifestation, but had failed to improve with antibiotics and medications for atopic dermatitis. KOH examinations were performed on his upper arm's lesion, and with detection of hyphae and isolation of Trichophyton rubrum by fungus culture, he was successfully treated with oral itraconazole 200 mg/day and topical flutrimazole. Tinea incognito refers to dermatophyte infections with atypical clinical presentation caused by previous treatment with steroid. Nowadays, the cases of tinea incognito have been increasing due to the increased usage of steroid and other immunosuppressants. Therefore, it is essential to include fungal infection in the differential diagnosis when cutaneous lesions are noticed in patients taking steroid and other immunosuppressants. Herein, we present a tinea incognito that clinically mimicked folliculitis in atopic dermatitis patient.
