RESUMO

Actinic keratosis (AK) is one of the most frequent pathologies in clinical dermatology. Approximately 10% of the prevalence of AK occurs at 30 years of age and rises to 80% at 70 years of life. This study conducted a split-face analysis based on Photodynamic Therapy (MALA-PDT) and 5-fluorouracil (5-FU) treatments in patients with AK. Clinical and histopathological studies evaluated each treatment's efficiency and side effects. Six patients were recruited between 50 and 70 years of age for this. MALA-PDT was applied on the right side of the face. A biodistribution time of 2 h, a dose of light of 36 J/cm2 (20 min irradiation), a spot for photoirradiation with a total area of 100 cm2, and a wavelength of 635 nm were used. (LINCE equipment MMOPTICS-Brazil). By fluorescence diagnosis, clinical and subclinical AK lesions were evidenced in the area called the "cancerization field." Two cycles of MALA-PDT were performed on each patient, and 5-FU was applied twice daily for 15 days. A 2-month follow-up post-MALA-PDT and post-5-FU was carried out. The treatment based on 5-Flu and MALA-PDT clinically shows the same response, but MALA-PDT is less aggressive than 5-FU. The treatment of AK based on MALA-PDT is a practical, inexpensive, and easy-to-use technique.

RESUMO

El síndrome de Goltz llamado también hipoplasia dérmica focal es una rara dermatosis que fue definida por primera vez por Goltz en el año 1962. Se la considera una genodermatosis de presentación esporádica (95% de los pacientes) aunque se han reportado casos de transmisión familiar. Compromete estructuras derivadas del mesodermo y ectodermo con predominio en el sexo femenino acompañada de herencia dominante ligada al cromosoma X. La mutación en el gen PORCN (locus Xp11.23) es letal en la mayoría de varones. La importancia de su publicación radica en su baja frecuencia y las manifestaciones clínicas características que ayudan al establecer el diagnóstico.


Goltz syndrome, also called focal dermal hypoplasia, is a rare dermatosis that was first defined by Goltz in 1962. It is considered a genodermatosis with sporadic presentation (95% of patients) although familiar aggregation has been reported. It compromises mesodermal and ectodermal structures, most frequently in female patients, its inheritance mode is dominant X linked. The mutation in the PORCN gene (locus Xp11.23) is lethal in the majority of males. The importance of its publication lies in its low frequency and clinical characteristic that helps in establishing the correct diagnosis.

RESUMO

Secretory breast carcinoma is an exceptionally rare mammary gland neoplasia described mainly in adult females and children of both sexes, and very rarely in the elderly. It has particular histopathological and immunohistochemical features and a favorable prognosis. We report the case of a 79-year-old Hispanic woman with a palpable breast mass. Currently, the patient is disease free after a followup period of 6 years without local recurrence or axillary lymph-nodes nor distant metastases.
