Severe pain in the scrotum during a soccer game sent a 14-year-old boy to his physician. The right testicle was swollen and exquisitely tender. On exploration, it was hemorrhagic and blue-black. A small incision in the tunica of the testis revealed arterial bleeding, which indicated that the testis was still viable. The right testicle was untwisted and fixed to the scrotum.

Over the previous 6 months, a 59-year-old man had experienced lethargy, fatigue, poor appetite, cold intolerance, and abdominal distention. His vital signs were normal; physical examination revealed periorbital and pretibial edema, distant heart sounds, and delayed reflexes.

These pruritic but otherwise asymptomatic lesions on the right upper arm of a 77-year-old woman first appeared about 1 year before she sought medical consultation. The patient's history included frequent, generalized pruritus, which was believed to be secondary to long-standing type 1 diabetes mellitus.

The wife of an 82-year-old man with Alzheimer's disease was concerned about her husband's poor posture. According to the woman, the patient had never sustained a back injury and had always maintained a sedentary lifestyle. He never smoked cigarettes and did not use alcohol. His history included multiple transient ischemic attacks (TIAs).

The bilateral breast hypertrophy seen on a 12-day-old boy's chest began 4 days earlier. This anomaly results from elevated levels of maternal circulating estrogen in late gestation that crosses the placenta and stimulates the baby's breasts. Both sexes are affected equally.

A 47-year-old woman presented to the emergency department with chest pain of sudden onset. The patient had no history of coronary artery disease, peptic ulcer, gastroesophageal reflux disease, or similar episodes of chest pain.

The initial complaint of a 79-year-old woman was of mild headache, neck pain, and sore throat. She had a history of hypertension, diabetes mellitus, and heavy cigarette smoking.

She had no arthralgias, visual loss, fever, or worsening head pain.

An 18-month-old girl was noted to have somatic overgrowth, macroglossia, macrostomia, fading telangiectatic nevi over the glabella and eyelids, vertical creases on the earlobes, a short nose with anteverted nares, and a long philtrum. She also had an ejection systolic murmur best heard at the left mid- and upper sternal border, compatible with an atrial septal defect.

A 40-year-old woman with a history of amenorrhea complained of recent headaches and galactorrhea for the last 6 months. A neurologic work-up revealed bitemporal hemianopia, and a radiograph of the skull suggested an enlarged sella turcica. A large pituitary adenoma disclosed by an MRI and a serum prolactin level of 360 µg/L led to a diagnosis of prolactinoma.

An obese 52-year-old woman with a 5-year history of type II diabetes mellitus had odynophagia and dysphagia for several days. She described the sensation as food “sticking” in her chest. She also complained of vaginal itching, polyuria, and polydipsia. The only remarkable finding on physical examination was candidal vaginitis. The patient did not smoke cigarettes or drink alcoholic beverages, and there was no history of recent weight loss.

Affected infants present shortly after birth with a large bowel obstruction secondary to transient dysmotility in the descending colon. Although the cause is unknown, immaturity of the colonic myenteric plexuses has been demonstrated in some cases. More than 50% of affected infants are born to mothers with diabetes. Other predisposing factors include hypoglycemia and sepsis.

For 2 months, a 31-year-old woman had had dyspnea and dull, continuous retrosternal pain. She was admitted to the hospital, and a helical CT scan of the thorax identified a saddle pulmonary embolism.

A 7-year-old boy presented with two testicles on the left side of the scrotum. The superior one was half the size of the inferior one, which measured 2 × 1 cm.

Biopsy specimens taken from the remaining testicle were normal.

This 15-year-old boy presented with a 3-year history of gradual, bilateral breast enlargement. He was otherwise healthy and showed normal pubertal development.
