Insights

Dermal inclusion cysts are benign tumors resulting from embryonic ectodermal entrapment. This report details a rare case of a large cyst in a child's ear canal, highlighting its infrequent occurrence.

Area of Science:

  • Dermatology
  • Embryology
  • Otolaryngology

Background:

  • Dermal inclusion cysts are benign neoplasms originating from ectodermal elements trapped during embryonic development.
  • Symptoms are typically caused by the mass effect of the developing cyst.

Observation:

  • A case report of a 23-month-old female child presenting with a solitary, large dermal inclusion cyst.
  • The cyst was located within the external auditory canal.

Findings:

  • This presentation represents an exceptionally rare occurrence of a dermal inclusion cyst in the external auditory canal.
  • Literature review identified only two previously documented cases in this specific anatomical location.

Implications:

  • This case underscores the importance of considering rare diagnoses in pediatric otolaryngology.
  • Further research into the embryological origins and clinical behavior of these cysts in unusual locations may be warranted.

Anatomy of the Ear01:16

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Accessory Structures of the Skin: Sebaceous Glands01:21

Accessory Structures of the Skin: Sebaceous Glands

A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

The Auditory Ossicles01:11

The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
