Benign Familial Chronic PemphigusSeptember 14th 2005
For 6 years, a 32-year-old man had a recurring rash on his back, shoulders, and chest. He stated that the rash appears in the spring, itches, and enlarges into ringlike areas. Previously, when treated with cephalexin, the rash had cleared within several weeks. Antifungal medication (econazole cream and oral terbinafine) had failed to resolve the rash.
A 58-year-old black woman sought evaluation of areas of increased pigmentation on her cheeks that had been present for many years. Bleaching agents did not lighten the area; new, non–nickel-containing eyeglass frames had no effect. A 3-week course of halobetasol cream failed to fade the hyperpigmentation.
A 72-year-old woman who had fallen and injured the left side of her chest came to the emergency department complaining of pain in that area. She was physically stable and not short of breath. A soft systolic murmur was heard over the left precordium; the lungs were clear. A posteroanterior chest film showed no rib fracture but it did show an enlarged heart and a large, calcified ventricular aneurysm.
Mongolian spots are benign, congenital blue-gray macules or patches commonly found in Asian, black, and Hispanic infants (and in 5% of white infants). They are most often located in the sacrogluteal area and the upper back. The lesions may be solitary or multiple, vary in color intensity, and frequently enlarge until about age 2, when they gradually fade and disappear. Approximately 5% persist into adulthood.
The patient reported that he had noticed the facial eruption a couple of months earlier. On examination, the lesion appeared more plaque-like and dense than is typical of rosacea. The differential diagnosis included lupus, mycosis fungoides, rosacea, and angiosarcoma.
