Summary
Extraskeletal chondroma, a rare benign tumor, can occur in soft tissue. This case highlights its association with flexor tendon triggering in an elderly patient.
Area of Science:
- Orthopedic Surgery
- Pathology
- Radiology
Background:
- Chondromas are benign cartilaginous neoplasms typically originating from bone.
- Extraskeletal chondromas are rare variants, lacking direct bone attachment.
- These soft tissue tumors can present diagnostic challenges.
Observation:
- A 76-year-old male presented with flexor tendon triggering.
- Imaging and subsequent biopsy revealed an extraskeletal chondroma.
- The tumor was located between the annular ligament and the flexor tendon.
Findings:
- The extraskeletal chondroma was confirmed as a benign cartilaginous neoplasm.
- Histopathological analysis showed features consistent with chondroma.
- The tumor's soft tissue location and association with tendon pathology were notable.
Implications:
- This case expands the known clinical presentations of extraskeletal chondromas.
- Understanding this association may improve diagnosis of tendon-related symptoms.
- Further research into extraskeletal chondroma etiology and management is warranted.

01:16Muscles of the Forearm that Move the Hand and Fingers
2.7K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

01:21Paracrine Signaling
59.7K
Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...

01:22Hair Cells
45.2K
Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.

Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.
