ABSTRACT

Los hemangiomas de la infancia (HI) son tumo-res vasculares que presentan un patrón evolutivo característico. Existe un subgrupo de HI que pre-senta un tipo de crecimiento distinto denominados hemangiomas de la infancia con crecimiento míni-mo o detenido (HI-CMD). En estos, el componen-te proliferativo no supera el 25% de la superficie total; además, afecta a niños de al menos dos meses de edad en la consulta inicial o a niños menores de dicha edad en los que se realiza un seguimiento mayor a 2 meses. Los HI- CMD con lipoatrofia son una variante poco frecuente de HI de la cual exis-ten escasos reportes en la literatura. El objetivo de nuestro trabajo es presentar un caso de HI-CMD con lipoatrofia en una lactante. Los HI-CMD presentan un desafío diagnóstico ya que deben ser reconocidos precozmente y diferencia-dos de otras lesiones vasculares.


Infantile hemangiomas (IH) are vascular tumors that present a characteristic evolutive pattern. There is a subgroup of hemangiomas that pre-sents a different type of growth called infantile hemangiomas with minimal or arrested growth (IH-MAG). In these, the proliferative component does not exceed 25% of the total surface; it also affects children of at least two months of age in the initial consultation or children under that age in which a follow-up of more than 2 months is carried out. IH-MAG with lipoatrophy is a rare variant of IH of which there are few reports in the literature.The aim of our report is to present a case of IH-MAG with lipoatrophy in an infant. IH-MAGs present a diagnostic challenge since they must be recognized early, and differentiated from other vascular lesions.

ABSTRACT

Granuloma annulare is a benign and self-limited cutaneous disease. Subcutaneous granuloma annulare is an uncommon variant seen almost exclusively in young children, characterized by firm nodules appearing more frequently in lower extremities, buttocks, hands and scalp. OBJECTIVE: To report a case of subcutaneous granuloma annulare and review its differential diagnoses and treatments. CLINICAL CASE: A 4 year-old male patient. Since 2 and a half years of age he presented asymptomatic firm subcutaneous nodules on the back of the left middle finger and later on the back of the left hand, right big toe, left frontal area and scalp. Excisional biopsy of some lesions from the scalp was consistent with subcutaneous granuloma annulare. Clobetasol 0,05% cream twice a day for 1 month was prescribed without response. CONCLUSIONS: Subcutaneous granuloma annulare must be considered within the differential diagnosis of subcutaneous nodules in children. In most of the cases a biopsy and histopathology of the lesions will be required to confirm the diagnosis. Due to its tendency to spontaneous resolution, treatment often is not necessary and periodic evaluation is recommended.

ABSTRACT

El granuloma anular es una dermatosis inflamatoria granulomatosa de carácter benigno y autolimitado. El granuloma anular subcutáneo es una variante poco común, que se presenta casi exclusivamente en niños menores y se caracteriza por la aparición de nódulos de consistencia firme de predominio en extremidades inferiores, glúteos, manos y cuero cabelludo. OBJETIVO: Reportar un caso de granuloma anular subcutáneo, revisar su diagnóstico diferencial y las opciones terapéuticas actuales. CASO CLÍNICO: Paciente de sexo masculino de 4 años. Desde los 2 años y medio con nódulos subcutáneos indurados asintomáticos, inicialmente en dorso de dedo medio mano izquierda, luego en dorso de mano izquierda, primer ortejo derecho, zona frontal izquierda y cuero cabelludo. La biopsia excisional de algunas lesiones de cuero cabelludo fue compatible con granuloma anular subcutáneo. Como tratamiento se indicó clobetasol 0,05% crema 2 veces al día en lesiones por 1 mes, sin cambio en las lesiones. CONCLUSIONES: El granuloma anular subcutáneo debe considerarse dentro del diagnóstico diferencial de nódulos subcutáneos en niños. En la mayoría de los casos se requerirá biopsia y estudio histopatológico de las lesiones para su confirmación diagnóstica. Debido a su tendencia a la resolución espontánea, generalmente se sugiere no tratar y controlar periódicamente.

ABSTRACT

Tineas are frequent infections caused by dermatophytes that are able to invade keratinized tissue, causing rounded, erythematous, scaly lesions. Nonetheless, in tinea incognito the lesions are modified because of inappropriate use of topical corticosteroids or calcineurin inhibitors, making it difficult to diagnose. We present a case of a 12-year-old male child that presents with erythematous lesions on the right eyebrow, which at first was diagnosed as a contact dermatitis, so corticosteroids were indicated. The lesions became more inflammatory and a fungus culture was requested, which was positive for Tricophyton mentagrophytes. The conclusion of this report is that tineas can mimic other dermatologic conditions therefore caution should be taken when prescribing topical corticosteroids or calcineurin inhibitors without diagnostic certainty because if lesions are caused by tinea, diagnosis and treatment may become more difficult.


Las tiñas son infecciones frecuentes causadas por dermatofitos, capaces de invadir tejido queratinizado, produciendo placas anulares, eritematosas y descamativas. Sin embargo, en la tiña incógnita esta clínica es modificada por el uso inapropiado de corticoides o inhibidores de calcineurina tópicos, dificultando su diagnóstico. Presentamos el caso de un paciente masculino de 12 años, con lesiones eritematosas localizadas en la región ciliar derecha. Se interpretó como una dermatitis de contacto y se indicaron corticoides tópicos, pero evolucionó con lesiones más inflamatorias. Se obtuvo un cultivo de hongos positivo para Tricophyton mentagrophytes. De este reporte se concluye que las tiñas pueden imitar otras condiciones dermatológicas. Por ende, se debe tener precaución al indicar corticoides o inhibidores de calcineurina tópicos sin una certeza diagnóstica. Ello, debido a que en el caso de corresponder a una tiña, se alteran las características clínicas, dificultando el diagnóstico y manejo.

ABSTRACT

El osteoma cutis (OC) es una lesión compuesta de tejido óseo en dermis y/o hipodermis. Se clasifican en primarios, cuando se desarrollan en piel sana, y secundarios, cuando aparecen sobre lesiones preexistentes. Mujer de 61 años con antecedente de linfoma de Hodgkin en remisión, presentó una lesión de larga data, desarrollada en piel sana, en primer dedo de la mano izquierda, que cursaba con brotes recurrentes y autolimitados de dolor y aumento de temperatura local. La exploración física mostró un nódulo pétreo, con úlcera de fondo calcáreo. El estudio histopatológico de la biopsia escisional reveló tejido óseo, sin otras lesiones cutáneas asociadas. El estudio complementario, incluyendo hemograma, función renal y hepática, calcio y fósforo séricos, PTH, TSH, vitamina D y calciuria fue normal. Descartándose alteraciones en el metabolismo calcio-fosforo y otras lesiones cutáneas preexistentes, se realizó el diagnostico de OC primario en forma de placa. El OC es una lesión benigna, pudiendo ser primario o secundario. Los secundarios representan cerca del 85% y se originan por la osificación de lesiones preexistentes tumorales o inflamatorias. Los OC primarios se presentan aislados o formando parte de síndromes como la fibrodisplasia osificante progresiva, la osteodistrofia hereditaria de Albright y la heteroplasia osificante progresiva. A pesar de la asociación a mutaciones en GNAS de OC y estos síndromes, el diagnóstico de ambos es fundamentalmente clínico. Los OC primarios sin síndrome asociado, se dividen en osteomas miliares de la cara y osteomas en forma de placa (plate-like OC), como este caso. Ante un OC primario, debemos descartar síndromes asociados a osificaciones heterotópicas.


Osteoma cutis (OC) is a lesion composed of bone tissue located in the dermis and/or hypodermis. It is classified as primary when it develops over healthy skin; and secondary when it develops over preexisting lesions. A 61-year-old woman with history of Hodgkin lymphoma in remission, presents a longstanding lesion located on the first finger of her left hand which developed over healthy skin, associated with recurrent and self-limited episodes of pain and increased local temperature. Physical examination reveals a stone-hard nodule, with a calcareous-bottomed ulcer. The histopathological evaluation of the excisional biopsy revealed bone tissue. Complementary studies included: complete blood count, renal and hepatic function, plasma calcium and phosphorus, PTH, TSH, vitamin D, and urinary calcium, all of them in normal ranges. Once systemic disease was ruled out, platelike OC was diagnosed. OC is a benign lesion which can be primary or secondary. Secondary OC represent nearly 85% of cases, and it corresponds to an ossification of preexisting tumoral or inflammatory lesions. Primary OC is less frequent, it appears isolated or as part of syndromes like fibrodysplasia ossificans progressiva, Albright hereditary osteodystrophy, and progressive osseous heteroplasia. GNAS mutations have been described in primary OC as in these syndromes, but the final diagnosis relies on the clinical picture. Isolated primary OC is classified in milliary osteomas of the face and plate-like OC, like our case. When facing primary OC, syndromes that present with heterotopic ossification must be ruled out.

ABSTRACT

Introducción: Existe poca información de la asociación entre Psoriasis y síndrome metabólico (SM) en Chile. Objetivos: Determinar la prevalencia de SM en psoriáticos chilenos. Material y métodos: Se realizó un estudio caso-control, con 487 pacientes (238 psoriáticos y 239 controles). En ambos grupos se analizó la prevalencia de SM además del exceso de peso, hipertensión arterial, diabetes mellitus 2, hipertrigliceridemia y niveles de HDL bajo. Resultados: Los psoriáticos presentaron mayor probabilidad de padecer SM versus los controles (35,29% vs 23,29%) OR 1,8 (1,20-2,66) p<0,05. Se asoció también con circunferencia abdominal aumentada (57,14% vs 36,94) OR 2,6 (1,79 - 3,78), exceso de peso (85,99% vs 63,45%) OR 2,46 (1,62 ­ 3,73) p<0,05 y diabetes mellitus 2 (13,45% vs 4,42%) OR 3,85 (1,79 - 8,26) p<0,05. Conclusiones: Se encontró una mayor prevalencia de SM, exceso de peso, circunferencia abdominal aumentada y diabetes mellitus 2 en el grupo psoriático en comparación al grupo control.


Background: There is a paucity of information about Psoriasis and metabolic syndrome (MS) association in Chile. Aim: To determine the MS prevalence in Chilean psoriatic patients. Material and Methods: A case-control study was conducted which included 487 patients (238 psoriatic patients and 239 controls). In both groups, MS prevalence, overweight, hypertension, diabetes mellitus type 2, hypertriglyceridemia and low HDL were analyzed. Results: Psoriatic patients were more likely to present MS than controls (35.29% vs 23.29%) OR 1.8 (1.20 to 2.66) p <0.05. In addition, it was associated with increased abdominal circumference (57.14% vs 36.94) OR 2.6 (1.79 to 3.78), overweight (85.99% vs 63.45%) OR 2.46 (1.62 to 3.73) p <0.05 and diabetes mellitus type 2 (13.45% vs. 4.42%) OR 3.85 (1.79 to 8.26) p <0.05. Conclusions: There is a higher prevalence of MS, overweight, increased abdominal circumference and type 2 diabetes mellitus in the psoriatic group compared with the control group.

ABSTRACT

La investigación traza una mirada holística y abarcadora sobre un tema que desde hace siglos desvela a cruceños y cruceñas, y que en los últimos cincuenta años interesa, atrae, importa, preocupa y genera simpatías y rechazos. Este tema de controversia, que a veces irrita, hasta se ha convertido en cuestión de Estado. Pero no deja de intepelar a propios y extraños: la identidad de lo cruceño, su construcción, sus manifestaciones y sus intentos de remate estatal.
