Intravascular histiocytosis: case report of a rare disease probably associated with silicone breast implant

Abstract Intravascular histiocytosis is a rare condition characterized by the aggregate of histiocytes within dilated dermal vessels. The diagnosis is mainly histophatological and immunohistochemical. We describe a case of a 55 year-old female patient presenting erythematous/purple patches on the breasts, back and limbs. She previously presented ductal carcinoma in the right breast in 2006 which was treated with mastectomy and proceeded to silicone breast implant in 2009. Clinical hypothesis was telangiectatic metastatic carcinoma. Histopathology showed vascular ectasia, thrombosis and recanalization of upper dermis small vessels. On immunohistochemistry, intravascular cells were CD 68+ and negative for estrogen and progesterone receptors, CK7, EMA and AE1/AE3 and endothelial cells were CD64+, leading to the diagnosis of intravascular histiocytosis.

Cutaneous manifestations of systemic lupus erythematosus - an experience from Bahawal-Victoria Hospital, Bahawalpur

To document the frequency of cutaneous manifestation of systemic lupus erythematosus [SLE]. It was a case-series collected from Dermatology Department and all four Medical Units of Bahawal-Victoria Teaching Hospital of Quaid-e-Azam Medical, Bahawalpur. A total of 100 patients with diagnosis of SLE and fulfilling the inclusion criteria were included in the study. All the patients were evaluated for the cutaneous manifestations of SLE. All the information was collected in a specially designed proforma and analyzed with the help of SPSS version 10. The mean age of the patients was 25.97 +/- 4.64 years. 92% patients were female and 8% were male. Out of 100 patients, 85% patient presented with cutaneous manifestations. Photosensitivity was seen in 40 [40%] patients, discoid rash in 35 [35%], malar rash in 25 [25%], and oral ulcers in 24 [24%]. SLE is predominantly seen among female patients of young age. Photosensitivity is most common presentation, followed by discoid rash

Vasculitis de vaso pequeño asociada a un producto oral usado para la caída del pelo / Small vessels vasculitis associated with a oral medication for loss hair

Se presenta el caso de una mujer de 36 años que consultó por lesiones vasculíticas en extremidades inferiores que aparecieron con relación al uso de un producto oral comercializado para la caída del pelo que contiene prosilium, vitaminas B6, B5, B8, hierro, zinc y vitamina E. Algunos elementos evolucionaron hacia la necrosis, especialmente en la pierna derecha. Los análisis de laboratorio permitieron excluir otras patologías asociadas con vasculitis, diagnosticándose una vasculitis cutánea de vaso pequeño posiblemente asociado a alguno de los componentes de dicho producto.

A 36 year old woman went for a consultation because of vasculitic lesions in her lower extremities that appeared after the use of a commercial oral product for hair loss which contains prosilium, vitamin B6, B5, B8, E, iron, and zinc. Some elements evolved towards necrosis, especially in the right leg. Laboratory analysis excluded other causes of vasculitis. The final diagnosis was a cutaneous vasculitis possible associated with some of the components of the hair loss product.

Vasculopatía livedoide: reporte de dos casos / Livedoid vasculopathy: a two case report

Vasculopatía livedoide es una enfermedad poco frecuente que se presenta principalmente en mujeres de edad media de la vida, antes de los cuarenta años. Es llamado también atrofia blanca, livedo reticular con ulceración de verano, vasculitis hialinizante segmentaria, o PURPLE (úlceras purpúricas dolorosas con patrón reticular de extremidades inferiores). Generalmente afecta los tobillos y se exacerba en primavera y verano. Su etiología es aún desconocida, pero se puede clasificar en formas primarias (sin ninguna patología asociada) y secundarias, ambos con un componente trombótico. A continuación se describen dos casos de vasculopatía livedoide: una mujer de 22 años con úlcera en pierna izquierda y púrpura retiforme en ambas extremidades. El estudio demostró que el cuadro estaba asociado o síndrome antifosfolípidos. El segundo caso es de una mujer de 47 años con uno vasculopatía livedoide secundaria o lupus eritematoso sistémico.

Livedoid vasculitis is a rare disease that occurs mainly in women under 40 years of age. It has also be ennamed atrofia blanche, hyaline segmentary vasculitis or PURPLE (purpuric ulcers with reticular pattem in low legs). It usually affects ankles and has an exacerbation during Spring and Summer seasons. It has an unknown etiology, and it has been classified as primary (or idiopathic) or secondary (associated to another disease). We describe two cases of livedoid vasculopathy: the first case is o 22-year-old women with ulcers and retiform purpura associated to antiphospholipid syndrome. The second case is o 47-year-old women with livedoid vasculopathy associated to systemic lupus erythematosus.

Cutaneous allergic vasculitis due to Solenopsis geminata (Hymenoptera: Formicidae) envenomation in Indonesia.

Severe cutaneous allergic vasculitis in a 60 year-old Caucasian male following the bite of the tropical fire ant, Solenopsis geminata (F.) is reported. Over the course of 8 weeks, the pathology progressed from an extensive red papular urticaria to vasculitis with peri-vascular inflammation and ulceration of the skin on the feet, ankles and lower limbs. Many of the affected areas of the skin eventually became covered with black eschar associated with further tissue breakdown and ulcer formation. After debridement, compression dressings, antimicrobial ointment and corticosteroids, complete healing eventually took place with only residual scarring. An awareness of the severe dermatologic reactions caused by a bite of S. geminata, albeit rare, is clinically important. Recognizing the characteristic skin lesions caused by the bite of S. geminata, treated with prompt administration of appropriate chemotherapy will speed recuperation of the patient and reduce possible secondary complications.

Eritema indurado de Bazin. Presentación de 4 casos / Erythema induratum of Bazin. Four cases report

El eritema indurado de Bazin es un cuadro anatomopatológico considerado como una tuberculosis nodular hipodérmica, caracterizada por presentar nódulos rojizos, indurados pequeños, separados por piel sana que ocasiona ligeras molestias y se localizan en la cara posterior de las piernas en mujeres jóvenes y que se presentan principalmente en invierno. Presentamos 4 casos que respondieron bien al tratamiento antifímico que aunado a estudios recientes basados en la amplificación de la reacción en cadena de la polimerasa (PCR) apoyan que el origen de este padecimiento es una reacción inflamatoria inapropiada a la presencia de M. tuberculosis en contra de lo expuesto por Lever, Ebel Hartinger, Schneider y Ondeut, que afirman que el eritema indurado de Bazin es una vasculitis de arterias y venas con necrosis grasa de origen desconocido y por lo tanto su tratamiento debe ser a base de corticoesteroides. El inicio de los 90 marca el surgimiento de la tuberculosis y con ello el advenimiento de nuevos casos de eritema indurado de Bazin, razón por la cual es importante que el médico general esté familiarizado con esta entidad para brindar una atención adecuada a estas pacientes.

Manifestaciones cutáneas del síndrome antifosfolípido / Cutaneous manifestations of the antiphospholipid syndrome

El Síndrome antifosfolípido es un transtorno caracterizado por trombosis arterial y venosa, pérdidas fetales recurrentes y, generalmente, trombocitopenia asocidada, en presencia de anticuerpos antifosfolípidos, tales como anticoagulante lúpico y anticuerpos anticardiolipinas. Dentro de la gran variedad de manifestaciones clínicas destaca la patología cutánea, que puede ser la primera expresión de la enfermedad. Las lesiones cutáneas incluyen: livedo reticularis vasculitis livedoide y necrotizante, tromboflebitis, necrosis y ulceración cutánea, máculas eritematosas, púrpura, equimosis, nódulos de la piel dolorosos y hemorragias en astilla subungueales, entre otras. Se presenta una revisión de los principales aspectos de la enfermedad (marcadores serológicos, patogenia, clasificación, clínica y tratamiento)
