[Epidermal growth factor receptor inhibitors side effects].

Epidermal growth factor receptor (EGFR) inhibitors are a new group of drugs used in the treatment of several malignancies. Three molecules are approved at the moment: gefitinib and erlotinib for the treatment of non-small-cell lung cancer, and cetuximab for colorectal cancer. These drugs originate cutaneous side effects with a high frequency: acneiform rashes, paronychia and generalized xerodermia. In this paper we review these common side effects and how to manage them.

[Systemic amyloidoses].

Amyloidoses are a heterogeneous group of diseases characterized by extracellular fibrillar protein deposits in the organs and tissues. These proteins are not biochemically related to each other, but share certain common characteristics, including apple green birefringence with polarized light after staining with Congo red, and beta-pleated sheet configuration through x-ray diffraction. Amyloid deposits may occur in many organs (systemic amyloidoses) or may affect a single tissue (localized or organ-specific amyloidoses). There are different classifications, but in this review the amyloidoses are organized by clinical symptoms, which are determined by the amyloid protein involved. Special attention is given to cutaneous and mucous membrane manifestations, which are often the first sign of the disease and are useful for early diagnosis, thus avoiding more aggressive procedures. The involvement of other organs is analyzed, as are the diagnosis, prognosis and treatment of systemic amyloidoses.

[Validation of the Spanish version of the Psoriasis Disability Index questionnaire in assessing the quality of life of patients with moderate-severe psoriasis].

INTRODUCTION: To assess the measurement properties of the Spanish version of the Psoriasis Disability Index (PDI) quality of life questionnaire for patients with moderate or severe psoriasis in ordinary clinical practice. PATIENTS AND METHODS: A study was carried out with 294 patients with moderate or severe psoriasis who had received therapeutic treatment. Sociodemographic and clinical variables were collected and the PDI and EuroQoL-5D questionnaires were administered at the baseline visit, and at 3 and 6 months later. The feasibility (percentage of patients responding to the questionnaire), validity of the construct, internal reliability and sensitivity to change were analyzed. RESULTS: Feasibility: 98.6 % of the patients answered over 80 % of the questions on the questionnaire. Validity of the construct: the PDI scores were correlated with the scores obtained in the Psoriasis Area Disability Index (PASI) (r = 0.33) and the Visual Analogue Scale (VAS) of the EQ-5D (r = -0.41) (p < 0.01). Longitudinal validity: the PDI questionnaire score after 6 months of treatment was correlated with the changes in the PASI index and the VAS (r = 0.39 y -0.51). Reliability: the internal consistency of the dimensions was high (Cronbach's alpha = 0.89). Sensitivity to changes: the size of the effect corresponding to the changes experienced by the patients who noticed an improvement in the severity of their psoriasis during the period between visits was 0.95. CONCLUSION: The Spanish version of the PDI has proven to be reliable, valid and sensitive to changes for use with patients with psoriasis in the Spanish population, although the test-retest reliability should be analyzed for clinically stable patients.

[Lupus miliaris disseminatus faciei associated with epidermal cysts].

Lupus miliaris disseminatus faciei (LMDF) is a chronic granulomatous disease, which tends to be located on the central part of the face. Its typical histological image is one of epithelioid granulomas with caseous necrosis. Its association with epidermal cysts has been described on few occasions in literature. We present a case of LMDF associated with epidermal cysts in a female Caucasian patient. This association suggests that the rupture of the epidermal cysts may be related to the appearance of LMDF. However, there are probably other factors that may also contribute to its pathogenesis.

Takayasu's disease with cutaneous involvement.

Takayasu's arteritis (TA) is a chronic inflammatory and fibrosing arteriopathy that can also involve cutaneous vessels. The disease typically presents with a prepulseless phase that overlaps or is followed by the characteristic pulseless stage. In both phases of TA, cutaneous manifestations may be present. Lesions considered to be 'specifically' associated with TA have been described most frequently simulating erythema nodosum, erythema induratum and pyoderma gangrenosum. We report 2 Caucasian patients with TA and nodular cutaneous lesions. Nine skin biopsies from these patients were studied. A necrotizing vasculitis was present in 5 biopsies. We review those patients with TA and well-documented cutaneous manifestations in the English literature, with special interest in nodular lesions, the most frequent cutaneous manifestation of TA in Caucasian patients. Biopsies from lesions with similar morphology frequently show different histological findings.

Superficial mucoceles and lichenoid graft versus host disease: report of three cases.

Superficial mucoceles are subepithelial extravasations of sialomucin that occur at the epithelial-connective tissue interface and are directly related to minor salivary glands. They have been described in association with oral lichen planus and, exceptionally, with chronic graft versus host disease. Three patients who underwent an allogeneic bone marrow transplantation for a chronic myelogenous leukaemia presented multiple superficial mucoceles and an oral lichenoid graft versus host disease.
