Follicular cysts are often seen as dermal, raised, fluctuant masses that are filled with keratinaceous debris. Cytologically, thick aggregates of keratinaceous material and many anucleated, mature squamous epithelial cells are observed.Nov 10, 2021.
What is the cytology of a sebaceous cell?
Diagnostic Cytology in Clinical Oncology Sebaceous cell tumors are characterized by the presence of cells with numerous small, relatively uniform, clear vacuoles in the abundant cytoplasm (Figure 7-14). The nucleus usually is small, round, and dark..
Mixed Cell Inflammation A pyogranu- lomatous response consists of a mixture of heterophils, epithelioid macrophages and multinucleated giant cells. A mixed cell inflammation indicates an established, active inflammatory lesion (originally known as chronic active inflammation).

Sebaceous cysts are less cellular than the other two and contain thick mats of nonstaining lipid-based secretory material. Low numbers of sebaceous epithelial cells may also be observed. These cells are cohesive. They have a moderate amount of basophilic cytoplasm filled with discrete cytoplasmic vacuoles.

How can I tell if a sebaceous cyst is cancerous?
Sebaceous cysts are common and harmless but, rarely, a sebaceous cyst can become malignant (cancerous). A sebaceous cyst is possibly cancerous if it has any of these characteristics:
A sign of infection such as :
pain
redness or pus drainage
A fast rate of growth after being removed. A diameter that’s larger than five centimeters.

How do I safely drain a sebaceous cyst?
Cephalexin or Cloxacillin is the first choice of antibiotics provided. Incision and drainage of the sebaceous cyst is recommended only when the cyst becomes swollen due to the fluid build up. Lidocaine with epinephrine can be used for hemostasis to reduce the bleeding during the incision and drainage process.

What causes sebaceous cysts?
Sebaceous cysts occur due to the buildup of sebum, an oily substance that keeps your skin and hair moisturized. Most sebaceous cysts are found on the face, the neck, the back, and rarely, in the genital area. Though they grow slowly and are usually painless, they can be uncomfortable and show up in embarrassing spots.

Where do sebaceous cysts usually appear?
A cyst generally is a slow-growing lump that can move easily under the skin. Sebaceous cysts are found under the skin. Palms of the hands and soles of the feet are the usual areas where a sebaceous cyst may be found. Blocked glands, trauma, as well as swollen hair follicles, are some of the causes of a sebaceous cyst.

Medical condition
Sebaceous carcinoma, also known as sebaceous gland carcinoma (SGc), sebaceous cell carcinoma, and meibomian gland carcinoma is an uncommon malignant cutaneous tumor. Most are typically about 1.4 cm at presentation. SGc originates from sebaceous glands in the skin and, therefore, may originate anywhere in the body where these glands are found. SGc can be divided into 2 types: periocular and extraocular. The periocular region is rich in sebaceous glands making it a common site of origin. The cause of these lesions in the vast majority of cases is unknown. Occasional cases may be associated with Muir-Torre syndrome. SGc accounts for approximately 0.7% of all skin cancers, and the incidence of SGc is highest in Caucasian, Asian, and Indian populations. Due to the rarity of this tumor and variability in clinical and histological presentation, SGc is often misdiagnosed as an inflammatory condition or a more common neoplasm. SGc is commonly treated with wide local excision or Mohs micrographic surgery, and the relative survival rates at 5 and 10 years are 92.72 and 86.98%, respectively.
