Abstract:
Figurate erythemas (FE) are a group of diseases defined by the presence of annular or arciform erythematous skin lesions that can occur anywhere on the body. Four different types of figurate erythemas have been described: erythema annulare centrifugum (EAC), erythema gyratum repens (EGR), erythema migrans, and erythema marginatum. While each of these presents with similar morphologies, the clinical and histopathological features are often unique and can aid in the diagnosis. Although the majority of the figurate erythemas are idiopathic, some may be associated with infections, stress, or other diseases. We present a novel case of recurrent figurate erythema in a 27-year-old male that appeared to be exacerbated by hydrochlorothiazide (HCTZ) and social stressors.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
