Insights

Abnormal Pacinian corpuscles can cause severe finger pain, a rare condition. Consider this diagnosis for unexplained finger pain alongside other soft-tissue tumors.

Area of Science:

  • Neuropathology
  • Hand Surgery
  • Oncology

Background:

  • Pacinian corpuscles are mechanoreceptors normally found in the skin.
  • Abnormalities or heterotopic locations of Pacinian corpuscles can lead to significant neuropathic pain.
  • Differential diagnosis of finger pain often includes common soft-tissue tumors.

Purpose of the Study:

  • To highlight heterotopic Pacinian corpuscles as a cause of severe finger pain.
  • To emphasize the importance of considering this rare condition in clinical practice.
  • To provide histopathological context for diagnosing abnormal Pacinian corpuscles.

Main Methods:

  • Case series review of three patients.
  • Histopathological examination of excised tissue.
  • Clinical correlation of symptoms and findings.

Main Results:

  • Three patients were diagnosed with heterotopic Pacinian corpuscles causing severe finger pain.
  • Histopathological findings confirmed the presence of abnormal Pacinian corpuscles.
  • This condition was identified as a cause of unexplained severe finger pain.

Conclusions:

  • Heterotopic Pacinian corpuscles are a rare but important cause of severe finger pain.
  • Clinicians should include abnormal Pacinian corpuscles in the differential diagnosis of unexplained finger pain.
  • Histopathological analysis is crucial for definitive diagnosis.

Somatosensation01:33

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
Assessment of the Abdomen III: Palpation01:23

Assessment of the Abdomen III: Palpation

Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...
Assessment of the Cardiovascular System III: Palpation01:27

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
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 the...
Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Pericarditis II: Clinical Features and Diagnostic Tests

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
