A 2-year-old girl presented with a 2-day history of urinary frequency and dysuria. Physical examination revealed complete fusion of the labia minora. Urine culture showed Escherichia coli with a colony count of 108/L. The child was treated with a 10-day course of amoxicillin that resulted in complete clearance of the urinary tract infection.
A 55-year-old woman complained of the sensation of a foreign body in her swollen left upper eyelid. A hard, painless lump was readily discerned during palpation. Eversion of the left upper eyelid revealed a fleshy, red, sessile conjunctival mass. No purulent drainage was noted.
Significant burning and tearing of her eyes and eyelid swelling occurred soon after a 49-year-old woman had a permanent at a hair salon. Her ears also showed signs of a toxic burn. She had never before experienced such a reaction.
A 19-year-old man was admitted to the hospital with malaise, fatigue, and intermittent fever (temperature of 38°C [100.4°F]) for the last 2 weeks. Physical examination revealed scarce purpuric lesions over the lower extremities; a pericardial friction rub was audible over the precordium when the patient was supine and seated, and the spleen was remarkably enlarged.
A 49-year-old man was concerned about a right flexor forearm lesion that had been increasing in size for 6 weeks. The light pink, well-demarcated, 5-cm, circular lesion featured slight peripheral elevation with ulceration, crusting, and a relatively clear central area. A culture of material from the lesion was negative for fungi. A potassium hydroxide evaluation was not performed.
A 30-year-old woman had an extensive psychiatric history of anxiety and depression. She was concerned that the numerous lesions on her body might be signs of possible infection or infestation. The patient was undergoing treatment for multiple addictions to drugs, primarily methamphetamine (“crank”).
A 6-year-old boy had a nonpruritic rash on his back for 10 days. There was no associated fever. The child's mother had placed a bandage over the lesions to prevent transmission to her other children.
For 2 months, a 73-year-old man had experienced dysuria, pneumaturia, and foul-smelling urine. He had an attack of diverticulitis a year earlier. At that time, he underwent a barium enema study, which showed multiple sigmoid colonic diverticula with spasm.
Levofloxacin, 500 mg/d, had been prescribed for a 74-year-old woman who had a urinary tract infection. The patient had type 2 diabetes and hypertension. She was allergic to sulfa drugs.
This rash, which covered a 68-year-old woman's body, was noted to have worsened during the past 2 months. A cephalosporin antibiotic had failed to clear the condition. The patient, a nursing home resident, suffered from emphysema, asthma, and heart disease. She had been receiving oxygen therapy and prednisone for 1 year.
A 72-year-old woman was hospitalized after 8 years of pain and swelling of the right metatarsophalangeal joint. (In this film, the dark area over the distal joint of the large toe is an artifact.) Results of a purified protein derivative tuberculin test were positive, and a chest film revealed apical changes compatible with old tuberculosis (TB).
A 35-year-old woman complained of pain or a burning sensation on her tongue when she ingested hot or acidic food and beverages. The white patch had spontaneously developed on her tongue 3 months earlier.
The appearance of a wound on the hand of a 102-year-old man concerned his nursing home's staff. Several months earlier, the patient had had a squamous cell carcinoma removed from the wound site and had undergone subsequent radiotherapy. A nonhealing skin ulcer developed at the site; a skin graft was performed.
A 15-year-old boy had been experiencing pain in his distal left leg for 7 months. There was mild swelling, and an x-ray film of the lower leg revealed a sharply marginated, vertically oriented, tubular lucency in the metaphysis of the tibia (A). There was no cortical destruction, periosteal reaction, or pathologic fracture. An MRI at high field strength was performed to narrow the differential diagnosis.
Fourteen months of intermittent, foul-smelling, perianal discharge prompted a 45-year-old man to seek medical evaluation. He also complained of occasional bright red rectal bleeding and soreness of the perianal region; he denied fever. The patient had undergone surgical drainage for episodes of perianal sepsis 2 years earlier.
A pruritic rash developed on the feet of a 40-year-old woman 2 days after she had worn a new pair of shoes for a few hours. The erythematous, papular, scaly eruption was more prominent on the right foot.
For 1 month, a 25-year-old woman had experienced discomfort in and around the left eye and diplopia. She was in good health; she reported no weight loss, excessive nervousness, heat intolerance, decreased strength, changes in the texture of hair or skin, or altered bowel habits. There was no personal or family history of goiter or other thyroid disease.
A 32-year-old man who was seropositive for HIV presented with a tender lesion on his right foot of about 3 months' duration. The patient's only medication was zidovudine. His CD4+ cell count was 120/μL.
A 48-year-old woman was admitted to the hospital with deep venous thrombosis of the right leg. She had a history of non-Hodgkin lymphoma, which was in remission. The patient had been a heavy smoker for many years.
After 5 weeks of undulating fever, weight loss, and night sweats, a 22-year-old man presented to the emergency department. He reported no significant medical history. The patient had recently completed a course of tetracycline followed by another of azithromycin for a presumed upper respiratory tract infection.
After 4 days of fever and a very sore throat, an 18-year-old man requested medical treatment. The patient's speech was barely intelligible because of the fullness in his throat. He was able to communicate, however, that he had great difficulty swallowing because of the throat pain and fullness.
Five days before this 1-year-old girl was brought to her doctor's office, a rash had developed on her left shoulder and the left side of her chest. The abrupt onset of a high fever (temperature, 41°C [105.8°F]) and irritability accompanied the outbreak of the rash. The child had a history of asthma and eczema.
Painful eczematous lesions at the angle of her mouth and the base of her nostrils had been bothering a 52-year-old woman for 3 days. Some of the vesicles had ulcerated and left a crust over the region. The patient said she had had similar attacks in the past. The diagnosis of recurrent herpes simplex virus 1 (HSV 1) infection was made. The patient was treated with acyclovir for 1 week, and all the lesions disappeared.
A 47-year-old woman from Southeast Asia presented with erythematous, asymmetric, anesthetic, sharply marginated plaques on her lower arms and hands. Because this patient had emigrated from a tropical climate, leprosy was suspected.
A 45-year-old man sought medical advice after suffering for 6 months with recurrent pain and a purulent discharge at the sacrococcygeal region. Two weeks before this consultation, an abscess on the patient's right buttock had been drained by another physician. The patient had insulin-dependent diabetes mellitus for 5 years; his medical history was otherwise unremarkable.
