RESUMEN
Addison's disease is a potentially life-threatening endocrine disorder. The classic dermatologic sign of Addison's disease is diffuse hyperpigmentation of the skin with focal hyperpigmentation of scars, nails, and the oral mucosa. Recognition of these dermatologic manifestations in a patient with otherwise vague constitutional symptoms warrants a consideration of Addison's disease.

We have presented a case of benign recurrent retroperitoneal schwannoma, though the inhomogeneity shown by CT suggested malignancy.

Blunt scrotal trauma may result in a variety of injuries, including testicular rupture, torsion, dislocation, hematoma, or contusion, as well as epididymal, scrotal, and urethral injuries. Testicular rupture occurs in 50% of patients with traumatic hematocele, and is probably frequently misdiagnosed. If not aggressively diagnosed and surgically repaired, testicular rupture may lead to testicular atrophy and loss. Traumatic testicular torsion must also be diagnosed early to preclude testicular loss. Testicular scan, when rapidly available, is indicated in any case of suspected traumatic torsion. If testicular scanning is unavailable or equivocal, surgical exploration is indicated. Once torsion is ruled out, ultrasound is a useful diagnostic technique in acute scrotal trauma to differentiate those scrotal and testicular injuries requiring surgical intervention.

A review of 13 cases of suspected child abuse in which radionuclide (RN) scans, radiographic skeletal surveys, and sufficient follow-up were available showed that the RN scans were insensitive, even though fractures were more than 48 hours old at the time of the scan. Frequently missed lesions included skull and extremity fractures. Furthermore, soft tissue and visceral abnormalities that were identified on radiographic examination went undetected on RN scan. We conclude that, although the RN scan may augment the radiographic examination, it should not be used alone to screen for the battered child.
