Infection

For more than 3 years, a 63-year-old man with a long history of parapsoriasis had multiple hyperpigmented, erythematous plaqueswith scaling on the abdomen, back, feet, and arms. Some lesions had a hypopigmented center. The patient denied systemic symptoms.

Sharp, shooting posterior neck pain prompted a 29-year-old man to seek medical attention. The pain began 4 days earlier and progressed to the point that it occurred with swallowing. He wore a wool scarf to restrict his cervical range of motion. During the history taking, he remained rigid and avoided rotation and flexion or extension of the spine.

This 8-year-old boy's mother thought her son had a fungal infection on his feet. Examination disclosed malodorous, nontender plaque formation on the weight-bearing surfaces of both feet. Within the plaques were round pits and furrows.

Although many lacerations are treated in the emergency department, primary care clinicians still see their share of such wounds. Most lacerations are incurred on the face and head (as a result of falls or altercations) or on the hand or lower arm (caused by tools, broken glass, or other sharp objects).
