Strict Anatomical Colocalization of Vitiligo and Elastolytic Granulomas.

Vitiligo is the most common depigmenting disorder, with a worldwide occurrence of 0.1-2% in the general population. Multiple conditions have been described colocalized in vitiligo patches, like psoriasis or lichen planus. However, actinic granuloma has not been described in association with vitiligo lesions so far.

Conjunctival Melanoma: A New Clinical and Therapeutical Approach.

Melanoma involving the conjunctiva is extremely rare. Graver prognosis has been reported with primary conjunctival melanoma than with their cutaneous counterparts [Collin et al.: Aust N Z J Ophthalmol 1986;14:29-34]. Among conjunctival melanomas, two significant risk factors for tumour-related death have been identified: (i) age older than 55 years and (ii) unfavourable tumour location (caruncle, cornea, fornix, palpebral conjunctiva) [Werschnik and Lommatzsch: Am J Clin Oncol 2002;25:248-255]. Here we present a rare case of lentigo maligna involving the palpebral, bulbar conjunctiva and the caruncle. We describe dermoscopic patterns observed and the use of a novel ocular melanoma therapy with topical imiquimod.

Bortezomib-induced cutaneous lesions in multiple myeloma patients: a case report.

Proteasome inhibitors are emerging as a promising class of anti-cancer therapeutic agents. Bortezomib (PS341) is the first proteosome inhibitor with clinical significance. It acts by blocking vital functions of tumoral cells in myeloma, inducing apoptosis. Its toxicity is usually manageable. Gastrointestinal symptoms, peripheral neuropathy, neuropathic pain and thrombocytopenia are described as the most common side effects. We report on a case of cutaneous lesions induced by bortezomib in a patient with relapsed multiple myeloma (MM).

Localized lichen myxoedematosus (papular mucinosis) associated with morbid obesity: report of two cases.

Cutaneous diseases are often found in obese patients but, to our knowledge, mucinous disorders have not been previously reported in association with obesity. Two cases of localized lichen myxoedematosus (papular mucinosis) in two women with morbid obesity are described. Both patients underwent a low-calorie diet for a 1-year period in one case, and for 4 months in the other one, as the only treatment. There was complete resolution of cutaneous lesions at the same time that an important weight loss was observed. Nevertheless, although spontaneous regression is not frequent, it could not be disregarded in either of these two cases.

Queratosis seborreicas irritadas simétricas en paciente con trasplante renal / Simetric irritated seborrhoeic keratoses in a renal transplant recipient

La queratosis seborreica es uno de los tumores epidérmicos benignos más frecuentes encontrados en la práctica clínica. Su transformación maligna es excepcional. Presentamos el caso de la aparición inusual de dos queratosis seborreicas irritadas simétricas en los brazos de un trasplantado renal (AU)

Estomatitis nicotínica del paladar: presentación de un nuevo caso / Stomatitis Nicotinica of the palate. Report of a new case

Se comunica un caso de estomatitis nicotínica en un varón de 65 años, fumador de pipa, que acude a consulta por presentar en el paladar múltiples lesiones blanquecinas indoloras. El estudio histológico muestra lesiones papulares relacionadas con la desembocadura de las glándulas salivales menores. Hoy se acepta que la estomatitis nicotínica típica cursa con lesiones blanquecinas orales de diferente conducta biológica que las leucoplasias con disqueratosis y que en modo alguno deben ser consideradas precancerosas (AU)

Linfangiectasias vulvares / Vulvar lymphangiectases

Las linfangiectasias cutáneas se han descrito clásicamente como una rara complicación tras mastectomía radical o tratamiento radioterápico o quirúrgico de carcinomas de cervix con o sin linfadenectomía. El principal factor desencadenante que se ha barajado es la obstrucción linfática profunda. Con posterioridad han aparecido en la literatura algunos casos cuyos antecedentes parecen tener más relación con factores locales en la matriz intercelular dérmica, que con daño profundo del sistema linfático.Describimos el caso de un linfangioma adquirido localizado en vulva tras una histerectomía radical con radioterapia posterior debido a un carcinoma de cervix y discutiremos la etiopatogenia de esta entidad (AU)

[Pancreatic disease in patients with HIV treated with didanosine (DDI)]. / Afectación pancreática en pacientes VIH tratados con didanosina (DDI).

Pancreatic involvement has been studied in 70 HIV infected patients, in diverse stages, that were treated with didanosine (ddI), both as monotherapy or associated to zidovudine; 38% of patients presented adverse reaction that obliged to withdraw the medication: pancreatitis (4%), hyperamylasemia (21%) and abdominal pain and/or diarrhea (12%). The possible causes in presentation of adverse effects were evaluated: route of infection, stage of HIV infection, use of pentamidine or trimethoprim-sulfamethoxazole for preventing Pneumocystis carinii pneumonia, administration of ddI in monotherapy or in combined form with zidovudine, time of treatment and level of CD4 lymphocytes. The outcome of adverse effects is related significantly only with the most advanced stage of HIV infection.

[Low grade non-Hodgkin's lymphoma after combined therapy for Hodgkin's disease]. / Linfoma no Hodgkin de bajo grado tras terapéutica combinada por enfermedad de Hodgkin.

The most serious complication of curative therapy for Hodgkin's disease is the development of a second malignancy. A patient who developed a low grade non-Hodgkin's lymphoma three years and a half after combined-modality therapy for Hodgkin's disease, is described. It is exceptional this type of non-Hodgkin's lymphoma as a second neoplasm after cytotoxic treatment for Hodgkin's disease. Pathogenic relationships between both processes are discussed.
