Palmo-plantar hyperkeratosis associated with HTLV-1 infection: a case report.

BACKGROUND: Palmoplantar hyperkeratosis is a cutaneous manifestation that had not been clearly associated with infection by the human T-cell lymphotropic virus, which is a retrovirus that in most cases does not develop clinical pathologies and its symptoms may be undetected. The skin is one of the most affected organs, however until now only seborrheic dermatitis, xerosis/ichthyosis and infective dermatitis associated with HTLV-1 have been described as cutaneous clinical manifestations of this disease. CASE PRESENTATION: We present the case of a 36-year-old male patient with serologically documented HTLV-1 infection, who presented symptoms of diarrhea, malabsorption due to Strongyloides stercoralis, and in whom a physical examination revealed an association with generalized xerosis and palmoplantar keratoderma confirmed by skin biopsy. Other infectious etiologies and malignancy were ruled out. This clinical manifestation was managed with dermal hydration, and skin care which improved the thickened skin and make it less noticeable. CONCLUSIONS: According to our experience, this is the first reported case of palmoplantar keratoderma associated with a human lymphotropic virus infection. This is a skin manifestation that has not been confirmed in conjunction with HTLV-I before. This implies that palmoplantar keratoderma is a new clinical manifestation of this infection, that should be considered in the initial approach of patients in endemic areas with these dermatological characteristics.

Tercer caso de vasculitis leucocitoclástica cutánea secundaria al uso de oxacilina: reporte de caso / Third case in the literature of cutaneous leukocytoclastic vasculitis secondary to oxacilin use

Resumen La vasculitis leucocitoclastica es una patologìa que compromete los vasos pequeños y cuya causa predominantemente se ha descrito como idiopatica. Se presenta el caso de una mujer de 78 años hipertensa, diabética y con enfermedad renal crónica en estadio 5, que presentó lesiones limitadas a la piel posterior a la administración de oxacilina para manejo de bacteremia por SAMS. La presentación clínica se basó en purpuras palpables predominantemente en miembros inferiores y lesiones dolorosas coalescentes que formaban ampollas de contenido hemorrágico. Estas lesiones resolvieron gradualmente después del cambio de la terapia mencionada anteriormente. La biopsia fue compatible con vasculitis leucocitoclástica, con paraclínicos que descartaron causas infecciosas y autoinmunes.

Abstract Leukocytoclastic vasculitis is a pathology that involves small vessels and whose cause has been predominantly described as idiopathic. The clinical case of a 78-year-old woman with hypertension, diabetic and chronic stage 5 kidney disease, who presented limited skin lesions after administration of oxacillin for management of bacteremia by MSSA. The clinical presentation consisted on palpable purpura predominantly in the lower limbs and painful coalescent lesions that formed blisters of hemorrhagic content. Lesions gradually resolved after the change of the therapy mentioned above. The biopsy was compatible with leukocytocastic vasculitis, with paraclinics who ruled out infectious and autoimmune causes.

Neuroparacoccidiodomicosis pseudotumoral en paciente inmunocompetente / Pseudotumoral neuroparacoccidioidomycosis in an inmunocompetent patient

La paracoccidioidomicosis es una micosis sistémica causada por el hongo dimorfo Paracoccidioides brasiliensis. La enfermedad es endémica en América Latina. Es la micosis sistémica más frecuente en Brasil, con mayor incidencia en las regiones sur, sureste y central, La enfermedad se adquiere por la inhalación del hongo, el cual se disemina a otros órganos mediante difusión linfohematógena y tiene dos formas de presentación aguda o subaguda comúnen niños y adolescentes y la forma crónica presente en adultos, con manifestaciones focales o multifocales dentro de la cual está el compromiso (poco frecuente) al sistema nervioso central. Se presenta un paciente masculino de 51 años quien debuto con alteración neurológica demostrada por paralisis del VI par craneal documentándose por TAC cerebral múltiples lesiones subcorticales y mescencefálicas asociadas a compromiso pulmonar, ganglionar y de glándulas suprarrenales; la histopatología comprobó la presencia de paracoccidiodomicosis.

Paracoccidioidomycosis is a systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis. The disease occurs in Latin America. It is the main systemic mycosis in Brazil, with the highest incidence in the southern,southeastern and central regions. The disease is acquired by the inhalation of the fungus, which spreads to other organs through linfohematogenic dissemination; it has two forms of presentation acute or subacute which occursin children and adolescents. The chronic form occurs in adults with focal or multifocal manifestations.This paper present a male patient aged 51 who debuted with paralysis of VIth cranial nerve, documenting multiple subcortical lesions, associated to with pulmonary, lymph node and adrenal glands involment. Histopathology showed evidence of paracoccidioidomycosis.

Síndrome de Cushing secundario a carcinoma de la glándula suprarrenal izquierda con metástasis hepáticas y trombosis tumoral masiva de la vena cava / Cushing´s syndrome due to a left adrenal cortical carcinoma with metastasis to the liver and a massive vena cava tumor thrombus

Se presenta el caso de una mujer de 47 años con cuadro clínico de siete meses de evolución caracterizado por aumento progresivo de peso, hipertensión arterial y diabetes mellitus de reciente aparición, hirsutismo facial y en tórax, alopecia frontal, alteraciones en la menstruación e hipopotasiemia. Se consideró el diagnóstico de síndrome de Cushing, por lo cual se iniciaron estudios e extensión para establecer su etiología. Durante su hospitalización presentó una evolución tórpida y falleció. En la autopsia clínica se encontró un carcinoma de la glándula suprarrenal izquierda, de 400 g, aproximadamente, con metástasis a hígado y trombosis masiva de la vena cava, lo que finalmente produjo su muerte.

A 47-year-old woman with a seven-month history of increasing weight, hypertension and recently diagnosed diabetes presented features of hirsutism, frontal baldness, amenorrhea and hypokalemia. These characteristics were considered diagnostic of Cushing´s syndrome, and studies were initialized to identify its etiology. During hospitalization, the patient presented a torpid evolution resulting in death. Clinical autopsy revealed a 400 g carcinoma in the left adrenal gland, liver metastasis and a massive vena cava tumor thrombus which was the final cause of death.
