Summary
A rare thymic neoplasm, initially nonspecific, grew over 12 years after chest trauma. Surgical removal revealed an epidermoid cyst, likely from migrating skin and fat tissue into the mediastinum.
Area of Science:
- Thoracic surgery
- Pathology
- Medical imaging
Background:
- Nonspecific thymic neoplasms can present after thoracic trauma.
- Long-term monitoring of mediastinal lesions is crucial.
Observation:
- A 65-year-old male experienced blunt thoracic trauma.
- A 47mm nonspecific thymic neoplasm was monitored for 12 years.
- The lesion showed significant growth over the observation period.
Findings:
- Post-thymectomy, the lesion was identified as an epidermoid lining cyst.
- Histopathology revealed thickened stratified squamous epithelium.
- The cyst's origin is hypothesized to be sequestered skin and fat tissue.
Implications:
- This case highlights a rare cause of mediastinal cysts.
- Understanding the etiology of thymic cysts aids in diagnosis and management.
- Further research into traumatic mediastinal inclusions is warranted.

01:20Classification of Epithelial Tissues: Glandular Epithelium
16.4K
The glandular epithelium is made of one or more epithelial cells modified to synthesize and secrete chemical substances. Glandular epithelia can be classified based on cell number. Unicellular glands have individual secretory cells scattered across the epithelial monolayer. In contrast, multicellular glands consist of a hollow tubular duct attached to the cluster of secretory cells located in the deep pockets.

02:07Oogenesis
58.4K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

01:27Acne Infection
94
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...

01:19Clinical Applications of Epidermal Stem Cells
2.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

01:21Accessory Structures of the Skin: Sebaceous Glands
5.5K
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...

01:27Ovarian Cycle
5.4K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...
