Recently, 2 putatively novel clinicopathological entities, macular arteritis (MA) and lymphocytic thrombophilic arteritis (LTA), have been described. Both exhibit an indolent chronic course and erythematous and hyperpigmented macules (MA > LTA) and papules/plaques (LTA > MA), often in a reticulated pattern on the lower limbs. Histopathologically, they show(More)
Many authors currently advocate 10-20% dosage increments between phototherapy sessions when treating psoriasis with narrowband ultraviolet B (UVB). However, such regimens are associated with a risk of significant erythema. In order to reduce this risk, a fixed increment regimen was developed using increments ranging from 30 mJ/cm2 for skin type II to 150(More)
BACKGROUND Acute febrile neutrophilic dermatosis, or Sweet syndrome (SS), is a condition that is presumed to be triggered by infectious disease agents. We report a case of SS associated with human granulocytic anaplasmosis (HGA), which is of interest because Anaplasma phagocytophilum infects, multiplies in, and disrupts the function of neutrophils, the key(More)
A student in a veterinary program noted an inflammatory tinea corporis on the right forearm after working with cows. Culture grew Trichophyton verrucosum. A nine-day course of treatment with oral fluconazole, 100 mg daily, resulted in prompt resolution. Awareness of the clinical presentations of barn itch, and familiarity with wet mount and histopathologic(More)
Skin fibroblasts from a patient with the photosensitive disorder hydroa vacciniforme were tested in vitro for DNA repair capacity. The rate of ultraviolet light (254 nm)-induced unscheduled DNA synthesis (UDS) in these fibroblasts was found to be 51-59% of the rate found in 4 normal fibroblasts strains. The patient had none of the clinical signs of the(More)
Pyruvic acid (PA) is an alpha-hydroxy acid with potent keratolytic properties. Fifty-six patients with common warts treated with two PA formulations were surveyed 2 to 29 months after beginning treatment (mean, 18 months). Thirty-eight patients used a 70 percent PA formulation with added 0.5 percent 5-fluorouracil (PA-5FU). Eighteen patients used a plain 70(More)
