The youngster's history included treatment for bronchitis, sinusitis, and conjunctivitis 2 weeks earlier.

A mildly painful, nonpruritic rash on the forearms and legs prompted a 42-year-old man to go to the emergency department (ED). The patient noted the rash when he awoke that morning.

Tortuous, dilated varicosities; multiple smaller caliber abnormal perforating vessels; and chronic brawny edema of chronic venous insufficiency (CVI) were seen on a 70-year-old man's left leg. He reported that the edema and discoloration had worsened over the last 15 years. The brawny edema stopped just above the ankle, indicating that compression by the patient's sock controlled the signs and symptoms of CVI.

After more than 15 years of wondering what the “white specks” on his legs were, a 64-year-old man consulted his physician. The patient was taking medication to control hypertension; he was otherwise healthy.

Coronary angiography was performed in a 54-year-old man with low-level stable angina. He had undergone percutaneous transluminal coronary angioplasty (PTCA) 3 months earlier. The angiogram showed tight stenosis of the proximal left anterior descending artery. The lesion was successfully dilated during a second PTCA, and a stent was placed using a flexible catheter.

For 3 years, a gradually enlarging, raised, purple, cystic lesion had been present on the left upper lip vermilion of a 51-year-old man. The asymptomatic lesion measured 0.5 cm in diameter. The patient was given a local anesthetic, and the lesion was excised by wedge resection in the office; pathologic examination confirmed the diagnosis of benign cavernous hemangioma.

A 68-year-old woman was referred from an acute care clinic for evaluation of a persistent cellulitis. Ten days before, erythematous, pruritic plaques developed on her ankles; these slowly enlarged, and pustules formed. The patient denied fever or chills.

Four months after a patchy, macular, erythematous spot erupted on the dorsum of a 63-year-old woman's left foot, the area became ulcerated, tender, and painful. The 1.2-cm ulcer was covered by a hemorrhagic crust surrounded by a cyanotic reticular discoloration of the skin.

Cutaneous and subcutaneous lesions of the extremities may be clues to the presence of rheumatic diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and the vasculitides. The history and physical examination can generally help confirm the cause. Skin biopsy is sometimes necessary for a definitive diagnosis; useful results depend on a technique that gives the depth necessary to see the pathology and proper interpretation of biopsy specimens by an experienced dermatopathologist.

Pyoderma gangrenosum (PG) is a chronic, recurrent condition characterized by cutaneous ulceration. In half of patients, PG is associated with an underlying illness, such as inflammatory bowel disease, RA, SLE, or a lymphoproliferative disorder.
