Summary
This study details a rare case of an epidermoid cyst found between tendons in a man's forearm. Surgical treatment was successfully performed for this unusual presentation of a skin appendage tumor.
Area of Science:
- Dermatology
- Orthopedic Surgery
- Surgical Pathology
Background:
- Epidermoid cysts typically arise from the hair follicle infundibulum.
- They commonly present as intradermal or subcutaneous tumors.
- Cysts located away from the skin are exceptionally rare.
Observation:
- A rare case of an intertendinous epidermoid cyst in the forearm was identified.
- The patient was a 68-year-old male.
- The cyst was located within the forearm's tendinous structures.
Findings:
- Histopathological examination confirmed the diagnosis of an epidermoid cyst.
- The cyst's origin and presentation were consistent with its follicular derivation, despite its unusual location.
- Surgical excision was the chosen treatment modality.
Implications:
- This case expands the known anatomical locations for epidermoid cyst occurrence.
- Highlights the importance of considering rare diagnoses in cases of forearm masses.
- Surgical management is effective for intertendinous epidermoid cysts.

01:17Muscles of the Forearm that Move the Hand and Fingers
2.3K
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...

01:16Muscles that Move the Forearm
3.5K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

01:19Bones of the Upper Limb: Humerus
6.7K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

01:15Bones of the Upper Limb: Ulna
4.0K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

01:09Bones of the Upper Limb: Radius
4.3K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

01:22Spinal Nerves: Plexus I
2.2K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
