Several years earlier, she had undergone surgery and chemotherapy for lymphoma but had been well since then.
A 75-year-old Hispanic woman presented with a slowly growing, asymptomatic facial lesion of about 3 years' duration.
Gross cysts (palpable fluid-filled macrocysts) are the most common lumps found in the breast. Cysts vary tremendously in size and number and may be microscopic or macroscopic.
A 21-year-old man slept in a car in upstate New York for three winter nights. Discomfort and swelling of his toes developed, which progressed to marked discoloration of the digits.
A 69-year-old woman, who was being seen regularly for treatment of psoriasis, was noted to have numerous open comedones on the sides of her face in association with photodamaged skin.
After having been bothered by these lesions for the past 9 months, a 27-year-old woman described the eruption as "itchy bumps under my arms."
Worsening episodes of pain and bleeding from the lesion on the dorsum of her foot brought a 16-year-old girl to her physician's office. The spot had gradually enlarged since she first noticed it about 3 years earlier.
A 23-year-old man complained of unsightly “flat warts” all over his chest. These lesions first appeared in early adolescence. The clinical suspicion of epidermodysplasia verruciformis was confirmed by a biopsy.

Following two witnessed tonic-clonic seizures, a 65-year-old woman with a history of chronic obstructive pulmonary disease was admitted to the hospital. Results of laboratory studies included serum creatinine level, 2 mg/dL; blood urea nitrogen level, 28 mg/dL; and erythrocyte sedimentation rate, 61 mm/h. The patient's antinuclear antibody (ANA) titer was 1:40 with a speckled pattern, and creatinine clearance was 17 mL/min. An ultrasonogram revealed bilateral small kidneys. CT and MRI of the head revealed no abnormalities.
For 2 months, a 22-year-old uncircumcised man noticed an asymptomatic, erythematous, static lesion on the glans penis. He had applied an over-the-counter “jock-itch” ointment for 2 weeks but to no avail. The young man was otherwise healthy and denied having dysuria or a history of sexually transmitted disease.
A 24-year-old man presented for evaluation of pruritic vesicles on both feet. Ten days earlier, dyshidrotic eczema had been diagnosed by another physician who prescribed triamcinolone ointment. The patient reported that the foot eruption worsened after the topical medication was applied.
This 6-year-old boy was brought to his physician for evaluation of a rash. The child had been running a fever and, for the past 48 hours, had been complaining of a sore throat, headache, and abdominal pain.
The rash on the neck of this 24-year-old man first appeared when he began to shave as a teenager. Pseudofolliculitis barbae affects 50% to 75% of black persons and 3% to 5% of white persons who shave.
Persistent, unremitting itch-which intensifies at night-is the chief complaint of patients with scabies. The female Sarcoptes scabiei mite (A) burrows into the stratum corneum, where she lays eggs. The parasite is transferred by intimate contact and fomites, such as infested clothing, towels, and bedding.
A painful swelling over the right lower eyelid with conjunctival injection was evaluated in a 28-year-old injection drug user. Cephalexin and corticosteroid ophthalmic drops failed to resolve the condition.
A 16-year-old girl had had tender, erythematous, nodular, shiny lesions on the extensor aspect of both shins for 2 weeks. There were no ulcerations or adenopathy. She denied fever, cough, sore throat, pruritus, and GI symptoms. Aside from oral contraceptives, she was not taking any medications.
This unusual manifestation of lichen planus is marked by inflammation around the follicular epithelium; on closer examination, erythematous follicular papules may be identified.
A mass on the right side of her face-over the right parotid region-had been growing for the past 4 years, according to this 65-year-old woman. There was no evidence of facial nerve involvement.
A comatose 29-year-old woman was brought to the emergency department. Her family reported that she had been well until 4 days earlier, when headache and fever developed. She went to another hospital at that time and was told she had an abscessed tooth. She was given erythromycin, and the tooth was extracted the following day. The patient's headache and fever worsened; a sore throat also developed, and a rash appeared on her trunk, arms, and legs. The family denied any HIV risk factors, unusual medical history, recent travel, and exposure to persons with infectious diseases.
This self-limited eruption is characterized by erythematous, scaling, oval-shaped macules on the trunk and proximal extremities. Most outbreaks begin with a single, large patch-a mother or herald patch-that typically is found on the trunk. Commonly, this lesion is confused with ringworm.
A 62-year-old man was admitted to the hospital with iron deficiency anemia, as demonstrated by low serum iron and ferritin levels and high total iron–binding capacity. He had had this condition for at least the last 5 years and had been treated with ferrous sulfate sporadically. The history coupled with the laboratory findings and the telangiectatic lesions on his lower lip led to a diagnosis of hereditary hemorrhagic telangiectasia, or Rendu-Osler-Weber disease.
Enlarging, coin-shaped lesions erupted on a 54-year-old man's posterior hands, arms, and buttocks 3 weeks before he sought medical evaluation. A few scattered lesions arose on his trunk and thighs as well. The lesions were mildly pruritic, but there were no excoriations. No discharge from the lesions was observed. The patient's history revealed no causative environmental factors.
A 45-year-old woman who had had several melanomas removed was concerned because of hyperpigmentation beneath her toenail. Some distal onycholysis was also noted. Because of the patient's history and the fact that she could not definitely recall injuring the toe, a partial nail evulsion was performed. Fortunately, the only finding was dried blood.
A pruritic rash of unknown origin had been present on the dorsum of a 26-year-old woman's foot for several months. Despite oral antibiotic therapy and applications of antifungal creams and topical corticosteroids, the condition did not resolve.
