Abstract

Insights

A new vascular skin condition, poikilodermatous plaque-like hemangioma, is described. This acquired condition presents as distinct plaques with specific clinical and histological features.

Area of Science:

  • Dermatology
  • Pathology
  • Vascular Biology

Background:

  • Presents a novel vascular proliferation termed poikilodermatous plaque-like hemangioma.
  • This condition is acquired and characterized by unique clinical and histological findings.

Purpose of the Study:

  • To summarize the clinical and histopathologic features of poikilodermatous plaque-like hemangioma.
  • To define this previously undescribed vascular proliferation.

Main Methods:

  • Retrospective case series analysis of 16 patients.
  • Collated clinical characteristics including demographics and morphology.
  • Summarized histopathologic features and immunohistochemical results.

Main Results:

  • Lesions typically appeared as solitary, erythematous-to-violaceous, poikilodermatous plaques on lower extremities and pelvic girdle.
  • Affected patients had a mean age of 72 years, with a male predominance and an indolent clinical course.
  • Histology revealed band-like vascular proliferation (postcapillary venules) in the superficial dermis, accompanied by fibrosis, edema, and elastic fiber loss; acanthosis was common despite an atrophic appearance.

Conclusions:

  • Poikilodermatous plaque-like hemangioma is a distinct, previously undescribed vascular proliferation.
  • The condition is defined by a consistent set of clinical and histological features.
  • Further research may elucidate the pathogenesis and optimal management.

Resistors In Series01:10

Resistors In Series

A resistor is an ohmic device that limits the flow of charge in a circuit. Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. The equivalent resistance of a combination of resistors depends on both their individual values and how they are connected. The simplest combination of resistors is the series combination. 
In a series circuit, the...

Series Resonance01:17

Series Resonance

The RLC circuit impedance is defined as the ratio of the supply voltage to the circuit current. Resonance in such a circuit occurs when the imaginary part of this impedance equals zero. This specific condition means that the inductive reactance is exactly equal to the capacitive reactance. The frequency at which this happens is known as the resonant frequency. Mathematically, the resonant frequency is inversely proportional to the square root of the product of the inductance (L) and capacitance...

Defining Psychology

Psychology is the scientific discipline dedicated to understanding both observable behavior and the internal mental processes underlying such behavior. It aims to comprehend human nature and apply this understanding to solve practical problems, enhance well-being, and improve societal outcomes. An example of psychology's application is the study of prosocial behavior, such as why and under what conditions individuals might help strangers in need. This process involves describing observed...

Trigonometric Fourier series01:17

Trigonometric Fourier series

Fourier series is a foundational mathematical technique that decomposes periodic functions into an infinite series of sinusoidal harmonics. This method enables the representation of complex periodic signals as sums of simple sine and cosine functions, facilitating their analysis and interpretation in various fields, including signal processing, acoustics, and electrical engineering.
The trigonometric Fourier series specifically expresses a periodic function with a defined period T using sine...

Convergence of Fourier Series01:21

Convergence of Fourier Series

The Fourier series is a powerful mathematical tool for representing periodic signals as an infinite sum of complex exponentials. In practice, this infinite series is truncated to a finite number of terms, yielding a partial sum. This truncation makes the approximation of the signal feasible but introduces certain challenges, particularly near discontinuities, known as the Gibbs phenomenon.
The Gibbs phenomenon refers to the persistent oscillations and overshoots that occur near discontinuities...

Series R—L Circuit Transients

In a series resistor-inductor (R-L) circuit, closing the switch at the start of the time period simulates a three-phase short circuit, a fault condition where all three phases of an unloaded synchronous machine are short-circuited. When there is no fault impedance and no initial current, the initial voltage is determined by the phase angle of the source voltage.
Using Kirchhoff's Voltage Law (KVL) to analyze this circuit helps determine the total asymmetrical fault current, which consists...
