Object radiography contrived to illustrate basic principles.

To add variety to radiologic teaching and to lower view box monotony, we imaged ordinary objects in circumstances that illustrate--caricature might be a better word--basic pathologic and radiologic principles. We tried to make each object image an interpretation challenge amenable to solution through logical application of such principles, and the result has added spice to our teaching sessions. Yet object radiography can play only an ancillary teaching role; we use it sparingly and always in combination with cases that illustrate the principles in question. Otherwise, the technique itself may add to the monotony it is designed to combat.

Clinical radiographs of the cadaver as a teaching aid in anatomy.

The use of clinical histories and radiographs of cadavers as a method for teaching anatomy was explored. This method was found to generate student interest in both anatomy and radiology, to make anatomy clinically relevant, and to supplement the laboratory manual by guiding the student through the dissection of medically or surgically complicated cases. It is an effective and workable method that is easily implemented and virtually cost free.

Neoplastic complications of neurofibromatosis.

Neurofibromatosis associated with secondary neoplasms is discussed. Neurosarcomas are the most common and most malignant secondary tumors in neurofibromatosis. Any sudden growth in a peripheral tumor in this disease should alert the physician to the possibility of malignant change and the need for biopsy. Only by early diagnosis and adequate excision can some of these patients be saved.

Photographic method of recording radiation fields using the localizer light for illumination.

By interposing a camera with a fish-eye lens between the collimator and the illuminated field, radiotherapy ports can be recorded using the localizer light for illumination. An acrylic mold of the camera was used to maintain alignment and immobilization during the necessarily long exposures. The authors consider this a very objective and accurate method of recording the topography of radiation ports.

Perilesional vitiligo in melanoma.

The malignant transformation of a plantar nevus is presented. Perilesional vitiligo developed concurrently with the onset of malignancy. The primary lesion was controlled surgically, but the patient succumbed to metastiatic melanoma within a year. The relation of perilesional vitiligo in malignant melanoma to the so-called halo nevus, and the immunologic significance of these discolorations is reviewed.

The radiographic wall-signs of ovarian dermoids.

Ovarian dermoids posses a distinct fibrous capsule which may be recognized radiographically by virtue of the contrasting effect of the greasy dermoid matter and the surrounding peritoneal fat. Part or all of the wall may be outlined in some projections even when the dermoid contents are not radiolucent enough to be recognized as such. Occasionally the wall of a dermoid cyst, heavily calcified or ossified, may be easily recognized radiographicaly.

Gigantic cystosarcoma phyllodes in a man with gynecomastia.

A 70-year-old man had a breast tumor for 50 years. The tumor, which weighed 8.6 kg, proved to be a malignant cystosarcoma phyllodes. It was successfully removed by a simple mastectomy with low axillary dissection, and a skin graft was performed. The lesion was associated with gynecomastia, and it is believed to have represented a cystosarcomatous transformation of a giant fibroadenoma.

Melanomas of the lower extremity among native Puerto Ricans.

The clinical features of 57 melanomas of the lower extremity occurring in native Puerto Ricans were studied. Whereas most melanomas of the lower extremity among Caucasians occur above the ankle, the group studied showed a predilection for the foot, particularly in the minimally pigmented zones (sole, heel, and nail bed), a distribution similar to that reported in black patients. The possibility that pigment-deficient areas may represent the target organ for sunligh-induced melanomas in Negroes and dark-skinned subjects is discussed.
