Gouty panniculitis is caused by the deposition of urate crystals in the subcutaneous tissue, accompanied by a lobular panniculitis. It presents as subcutaneous nodules, most commonly located on the lower extremities. Being an unusual clinical presentation of gout, the sonographic findings of gouty panniculitis have been scarcely described in the literature. Our report describes the ultrasound features we found in a case of gouty panniculitis and the usefulness of this technique for diagnosis and monitoring of this disease.

We report the case of a 16-year-old girl with a history of idiopathic precocious puberty and normal results on pituitary imaging scan. Ten years later, a new cranial magnetic resonance imaging scan was performed due to worsening of episodes resembling Horton's headache and a lesion suggestive of pituitary bleeding was detected. The headaches diminished with glucocorticoid administration but a severe complication, steroid psychosis, occurred. Surgical treatment and pathological study of the lesion led to the differential diagnosis between craniopharyngyoma and xanthogranuloma of the sella turcica. The clinical progression of the tumor (not visualized 10 years previously), together with preservation of pituitary and visual function both before and after surgery, gross total removal of the tumor (difficult to achieve with craniopharyngioma) and the absence of recurrence provide strong support for the diagnosis of xanthogranuloma of the sella turcica., (Copyright © 2008 Sociedad Española de Endocrinología y Nutrición.

Renal cell carcinoma have a great capacity of dissemination and have a great variety of clinical presentation. We exposed a clinical note of a patient diagnosed of renal cell carcinoma who developed hematuria and acute urinary retention due to a penis metastasis. Next we review the literature about this topic.

Objectives: To analyze the evolution of prostate cancer (PCa) in our community health area over the last years, in terms of incidence, clinical-epidemiological characteristics, and cancer-specific mortality., Methods: Retrospective analysis of the medical records of patients with PCa in our hospital over the 1991-2003 period. We calculated the annual incidence rates for our community health area as well as its trend over the period of study. Changes of several clinical-epidemiological parameters over time were studied. The evolution of PCa mortality was also analyzed., Results: 730 patients with PCa were evaluated. Median age and PSA at diagnosis were 69 years and 11.4 ng/ml, respectively. 60.5% tumors were detected in a localized clinical stage, and 18.6% were metastasic. 30.4% of PCa in the study (the most numerous group) had a Gleason score between 5 and 6. A constant increase of PCa incidence was observed with an annual percentage increase of 5.5% (p < 0.001). Standardized incidence rate for the year 2003 Spanish population pyramid was 100.9 cases/100,000 males. A significant trend to a greater proportion of PCa cases diagnosed by uncontrolled screening was observed, being the cases currently detected after symptoms only a small proportion (p < 0.001). Decreases in the age at diagnosis (p < 0.001), PSA level (p < 0.001), proportion of advanced clinical stages (p < 0.001), as well as proportion of cancers with well-differentiated Gleason score (2-4) (p < 0.001) were also detected. PCa mortality adjusted by the population pyramid was 8.7 deaths/100,000 males in the year 2003., Conclusions: We found an increase in the incidence of prostate cancer in our community health area over the last years, parallel to an increase in the proportion of cases detected by screening in asymptomatic population. Because of that, tumors currently detected tend to appear in younger ages, with lower PSA levels, and localized clinical stages.

Study Design: The case of a 16-year-old patient with an osteochondroma in T11 and scoliosis is reported., Objective: To describe the treatment of an osteochondroma with scoliotic deformity and the imaging methods used for the diagnosis., Summary of Background Data: Osteochondromas arising in the vertebral column are rare. However, spinal involvement is found with some regularity because osteochondromas are among the most common benign tumors of bone., Methods: The clinical history, plain radiographs, computed tomography, and magnetic resonance imaging, and pathologic findings of the reported patient were reviewed. The medical literature also was reviewed., Results: The patient was treated with surgery in an attempt to remove the tumor and correct the aesthetic deformity. The results were satisfactory, with an improvement of the thoracolumbar scoliosis from 45 degrees to 18 degrees., Conclusions: Osteochondromas of the vertebral column may cause scoliosis. Computed tomography and magnetic resonance imaging are necessary for evaluating the origin, size, and characteristics of the tumor. In this case, surgical management involved resection of the tumor and correction of the scoliotic deformity.
