All elements of the skin are affected by age. In this 2-part article, I will discuss how the blood vessels, the lymphatics, and the ground substance- which surrounds these vessels-respond to age, and I will show how the aging elements of the vasculature can engender a variety of pathological cutaneous conditions.
Given the risk of skin cancer and the benefit of vitamin D production, what should I tell my patients about sun exposure?
During a routine physical examination, multiple, randomly distributed, fleshcolored nodules were noted on the trunk, arms, and face of a 62-year-old man. The lesions measured 0.5 to 1.0 cm and appeared slightly pedunculated. The patient had had the lesions since he was a teenager; they were not painful. He also had hypertension, for which he was taking lisinopril (20 mg once daily).
Osler nodes may accompany bacteremia without endocarditis, septic endarteritis, typhoid fever, gonococcemia, systemic lupus erythematosus, and nonbacterial thrombotic endocarditis.
A 58-year-old man with type 2 diabetes, nephrolithiasis, and benign prostatic hyperplasia presented with bilateral periorbital ecchymoses and left subconjunctival hemorrhage. The ecchymoses had spontaneously appeared 3 days earlier; the patient had no history of trauma or falls. He also had difficulty in voiding, characterized by increased frequency, hesitancy, and diminished urine stream.
A 17-year-old boy presents with an intermittent asymptomatic rash on his cheeks that he says started 1 year earlier after a trip to Arizona over spring break. He is otherwise healthy, takes no medications, and has no other rashes.
A 41-year-old man is seen for routine physical examination. Apart from mildly elevated cholesterol 2 years ago and a bout of bacterial bronchitis last winter, he has been healthy. Says he has had “bad acne” since age 21. Has applied drying agents that worsened it and that sting; has “sensitive skin” problems from creams. Now prefers to ignore his facial skin.
This lesion had appeared in the right groin of a 60-year old man and had slowly enlarged over a month (A). Two years before this evaluation, he had undergone total prostatectomy with lymph node dissection for prostate carcinoma. Metastatic disease was found in a resected lymph node, and he underwent multiagent chemotherapy.
For several weeks, a 25-year-old man has been bothered by a pruritic rash on his hands. He has a history of allergies but is otherwise healthy. He owns 2 dogs.
For 1 month, a 54-year-old woman has had an intensely pruritic eruption on her abdomen, arms, and anterior thighs. She has long-standing hypertension and type 2 diabetes mellitus, which are treated with an angiotensin-converting enzyme inhibitor/diuretic and an oral hypoglycemic agent.
This worsening rash developed after a 40-year-old man was treated with amoxicillin for an upper respiratory tract infection. When the rash started, the amoxicillin was discontinued and azithromycin was prescribed; however, the rash has persisted. The patient has no history of allergies or rashes. He takes no other medications.
Syphilis took Europe by storm at the end of the 15th century in what was to become a sweeping epidemic. Before 1495, it was unknown or perhaps was attributed to other disease processes, such as leprosy.
A 76-year-old man is seen because of redness below the right eye. Has long-standing “lazy eye” on the left, which is chronically deviated outward. Has lived in nursing home for some years due to self-care deficit from memory loss. No recent eye surgery, conjunctivitis, sinus infection, or periocular trauma.
This rash erupted on the upper body of a 58-year-old woman in late August. It was mildly pruritic and nontender. The patient had not started any new medications and was not taking photosensitizing drugs. She had Sjögren syndrome; the rest of her history was noncontributory. Subacute cutaneous lupus erythematosus (SCLE) was diagnosed. SCLE typically affects white women aged 30 to 40 years.1 It presents as nonindurated, nonscarring, erythematous plaques with or without a fine scale that may progress into a diffuse, widespread, papulosquamous or annular lesion with central hypopigmentation or telangiectasia.
A 44-year-old man seeks evaluation of itchy spots of 2 years’ duration on both forearms near the elbow. The condition failed to respond to topical corticosteroids prescribed by other physicians. Skin biopsy results were inconclusive; they showed only mild inflammation.
I applaud Dr Henry Schneiderman for his remarks in a recent “What’s Your Diagnosis?” column regarding the proper way to perform auscultation and percussion of the chest (CONSULTANT, October 2008, page 874). I am a family practitioner, and I examine my patients on their bare skin.
This lesion appeared on the left outer thigh of a 28-year-old man after he took amoxicillin. The antibiotic had been prescribed for an upper respiratory tract infection with fever. Two years earlier, a lesion had appeared in the same anatomical region after ingestion of amoxicillin. A skin biopsy of the current lesion confirmed the diagnosis.
An 89-year-old woman is seen because of a white area on the tongue. She has been hospitalized on a behavioral health unit for 2 weeks; 1 day ago, enoxaparin was begun for a new left leg deep venous thrombosis. Recent antibiotic therapy for a urinary tract infection; candidal vulvitis followed and was treated with topical clotrimazole. Has penicillin allergy.
Cocaine abuse is associated with many dermatological manifestations, vasculitides, and infections. Consider this diagnosis in patients with unexplained chronic skin lesions, an ambiguous medical history, previous examinations that found no source of symptoms, labile affect, and delusional behavior.
These extensive, smooth, irregular masses of pigmented tissue on the earlobes of a 28-year-old woman are keloids. The patient had her ears pierced at age 6 years; the masses began to develop when she was about 9 to 10 years old. The right earlobe mass arose first and is larger. She had one other keloid of 1 cm on her chest that had developed after a scratch. She denied any other skin lacerations or incisions.
Methicillin-resistant Staphylococcus aureus (MRSA) was once considered a strictly nosocomial pathogen. Over the past decade, however, MRSA has emerged as a prominent cause of community-associated infections in both adults and children. Although community-associated MRSA strains occasionally cause severe invasive infections, they are most frequently isolated from patients with skin and soft tissue infections.
A previously healthy 16-year-old boy presents for evaluation of a slightly pruritic, nontender, generalized rash.
Untreated tinea versicolor has no grave sequelae. However, cutaneous dyschromia-hypopigmentation or hyperpigmentation-will persist without treatment (Figure).
For 25 years, a 74-year-old man had an intermittent, painful, and pruritic rash that caused cracking and erosions in the axillae and groin. It worsened with sweating and in the summer and also when clothing or skin rubbed against the eruption. The patient’s father, a paternal uncle, and all 3 of the patient’s daughters had a similar rash. Cetirizine and a combination of xipamide, bacitracin ointment, clotrimazole, and triamcinolone cream were prescribed to treat the rash.
For about 10 years, a 26-year-old man had recurring cystic lesions on his scalp that would periodically enlarge, shrink, and occasionally drain. One lesion had been excised by another physician, but it later recurred. The patient had been taking minocycline (100 mg) daily for this condition.
