[Porokeratosis in a patient with dermatomyositis].

There are several reports of porokeratosis in the context of immmunosuppressive diseases. These mainly include organ transplant, HIV infection, lymphomas and some inflammatory and autoimmune diseases commonly treated with immunosuppresive drugs or chemotherapy. Disseminated superficial actinic porokeratosis is the clinical variant of porokeratosis that most frequently develops in immunosuppressive states. We report a case of porokeratosis in a woman with dermatomyositis.

Effect of intra-aortic occlusion balloon in external thoracic compressions during CPR in pigs.

This study was performed to compare the effectiveness of external thoracic compressions with and without intra-aortic occlusion balloon with capnography and coronary and cerebral perfusion pressure (CPP) in the normothermic and traumatic-less cardiopulmonary arrest provoked by a ventricular fibrillation in pigs. This was an experimental study (cross-over study) in 14 pigs with similar characteristics (23 +/- 2 kg, 10-12 weeks of age). After an 8-minute nonintervention period, the cardiopulmonary resuscitation (CPR) consists of 4 periods of 5 minutes alternating CPR with and without intra-aortic occlusion balloon. Main outcomes measured are end-tidal CO(2) (ETCO(2)); intra-aortic, coronary, and cerebral perfusion pressures; blood gas analysis; and blood lactate concentration. At the end of each period, levels are obtained. Postmortem study was made. Inflation of the occlusion balloon provokes an expansion in the ETCO(2) of about 38%. The coronary perfusion pressure initially goes from 10.21 to 29.0 mm Hg after the occlusion of the aorta, which means an increase of 150%. The CPP goes from 12.54 to 39.71 mm Hg after the balloon was inflated, which means an increase of 200%. In all cases the differences are statistically significant (P <.0001). These increases are less important in the final periods. Intra-aortic balloon occlusion increased ETCO(2), coronary, and cerebral perfusion pressures. An early application of this technique was important.

Plantar hyperkeratosis due to Fusarium verticillioides in a patient with malignancy.

We report the case of an 82-year-old man with hyperkeratosis of the right sole caused by a Fusarium verticillioides infection mimicking verrucous tuberculosis; the infection was confirmed by direct potassium hydroxide microscopy, biopsy and cultures. The biopsy specimen showed an unusually deep invasion of fungal elements into the epidermis. This is an uncommon presentation in a localized cutaneous infection by Fusarium but in this case, repeated local injuries were the portal of entry initiating the process. Clinical patterns of cutaneous fusarium infections in general are also discussed.

Actinic superficial folliculitis.

We report a 31-year-old man with sterile follicular pustules on the shoulders, trunk and arms, recurring every year within 48-72 h of the year's first exposure to the sun. Both clinical and histological characteristics match those of the condition first described in 1985 under the name actinic superficial folliculitis. We discuss possible relationships with other similar conditions.

Hair follicle nevus: case report and review.

Hair follicle nevus has been variously defined as a specific type of neoplasm with follicular differentiation or as a synonym for trichofolliculoma; the latter view has predominated in recent years. We report a nodular lesion that was identified histopathologically as a hamartoma with follicular differentiation and that systematic serial sectioning showed not to be a trichofolliculoma. After reviewing previous descriptions of lesions diagnosed as hair follicle nevus, and in the light of our own observations, we believe that hair follicle nevus is a distinct type of adnexal hamartoma.

Traumatic eosinophilic ulcer of the oral mucosa: a misdiagnosed entity.

We report a case of and review the literature on eosinophilic ulcer of the tongue. This is a benign entity frequently unrecognized in clinical practice, with only occasional mention in the literature, the clinical signs of which are easily confused with those of squamous cell carcinoma. Although the histopathologic appearance of this entity is distinctive, its clinical course and rapid healing without therapy themselves constitute strong diagnostic clues, making diagnostic or therapeutic bloody methods generally unnecessary.

Hairy leucoplakia and HIV-2--a case report and review of the literature.

Type 2 human immunodeficiency virus (HIV-2), originally confined to West Africa, has lately appeared with increasing frequency in Europe. Oral lesions affect a large proportion of patients with AIDS. Hairy leucoplakia (HL), a clinical expression of Epstein-Barr virus (EBV), is a lesion of the oral mucosa (usually the lateral margin of the tongue) that is observed in patients who are immunocompromised due to HIV or, more rarely, due to immunosuppressive medication or other causes. We review the definition, clinical signs, histopathology, diagnosis, prognosis and treatment of HL, and report the (to our knowledge) first detailed description of an HIV-2-seropositive patient with HL, which affected the lateral and dorsal tongue and was the first clinical sign of HIV infection (this patient was at that time only the second native Spaniard in whom unique HIV-2 infection had been detected). EBV detection and subtyping by in situ hybridization and polymerase chain reaction were performed in paraffin-embedded tissue from the HL lesion of the dorsal tongue; EBV-1 and EBV-2 were detected by the latter technique.
