ABSTRACT
Herpes folliculitis is a rare manifestation of herpes virus infection. It usually represents a diagnostic challenge, due to the absence of characteristic skin manifestations such as vesicles or pustules. The reported cases are mainly associated with varicella zoster virus (VZV) and less commonly with herpes simplex viruses (HSV-1 y HSV-2). We report a 51-year-old male with a relapsing non-Hodgkin Lymphoma under chemotherapy, with history of extensive follicular lesions lasting one month. The pathologic study of the lesions was consistent with necrotizing herpes folliculitis. The patient was treated with Valacyclovir, achieving remission of the lesions. The appearance of folliculitis, especially in an immunocompromised patient, should raise the suspicion of herpes virus infection. Polymerase chain reaction may help to elucidate the diagnosis when pathologic findings are non-specific.

Acquired reactive perforating collagenosis is a perforating dermatosis characterized by transepidermal elimination of collagen. It is frequently associated to diabetes mellitus and chronic renal insuffciency, but it is also related to other systemic diseases. The lesions tend to resolve once the underlying condition is treated. We report two patients with the condition. A 65 year-old diabetic female on hemodialysis consulted for multiple itching cutaneous ulcers lasting one year. On physical examination, hyperpigmented papules and nodules were observed. A 65 year-old female with chronic renal failure in hemodialysis consulted for itching lesions in hands, forearms and arms. On physical examination, hyperpigmented lesions with ulcers, erosions and crusts were observed. In both cases, the pathological study of the lesions disclosed a reactive perforating collagenosis.

La radiocirugía ha sido integrada fundamentalmente a todas las prácticas dermatológicas. El procedimiento es rápido, los resultados cosméticos en el postoperatorio son muy superiores, se obtiene una menor incomodidad para el paciente, una curación más rápida, menor infección y excelentes muestras histopatológicas. Por lo tanto, los médicos deben interesarse en continuar desarrollando esta valiosa y variada modalidad

La homeostasis de los seres vivos aeróbicos se ve constantemente amenazada por la formación de moléculas químicamente inestables y altamente reactivas llamadas radicales libres. Estos pueden generarse por agresores metabólicos endógenos (metabolismo celular) o exógenos, como el tabaco, el ozono y la radiación ultravioleta. Se les relaciona con una serie de condiciones patológicas, como la carcinogénesis, la aterosclerosis y el envejecimiento tisular. Los antioxidantes son sustancias que al interactuar con estos radicales libres previenen o demoran su acción deletérea. En la dieta se encuentran diversos compuestos que pueden contribuir a la modulación interna de los antioxidantes, apartándolos en forma directa o como cofactores. Es importante conocer estos antioxidantes dietarios, saber sus requerimientos mínimos y los potenciales riesgos por uso inapropiado

Los hemangiomas son los tumores más frecuentes de la infancia, con una incidencia estimada de 10 por ciento - 12 por ciento, ocurriendo la mayoría en infantes prematuros de menos de 1000 g. Durante la fase de crecimiento rápido, aproximadamente el 5 por ciento - 13 por ciento de los hemangiomas se ulcera. Las lesiones ulceradas son dolorosas, pueden sangrar y ser factor de riesgo para sobreinfecciones bacterianas, particularmente cuando se comprometen labios, genitales, la región perirrectal o pliegues. El manejo depende de la edad del paciente, localización, tamaño y etapa del crecimiento del hemangioma. Nosotros revisamos las diferentes modalidades terapéuticas del hemangioma y los cuidados locales de la herida cuando éste se ulcera.
Hemangiomas are the most common tumor of infancy, with an estimated incidence of 10-12 percent most often occurring in premature infants weighing less than 1000 grams. During the rapid growth phase approximately 5-13 percent of the hemangiomas ulcerate. Ulcerated lesions are painful, may bleed, and risk bacterial infection, particularly when the lips, genitalia, perirectal area or flexures are involved. Management depends on the age of the patient, location, size, and stage of the tumor. We review the different therapeutic modalities of hemangiomas, as well as local wound care when ulcerated.
