Gardner's syndrome and steatocystoma multiplex. Two unusual genetically determined conditions occurring in same patient. (1/183)
A 43-year-old man is described who had Gardner's syndrome and steatocystoma multiplex. These two unusual genetically determined conditions were associated because he had inherited the Gardner's syndrome from his father and the steatocystoma multiplex from his mother. (+info)Contralateral deafness following unilateral suboccipital brain tumor surgery in a patient with large vestibular aqueduct--case report. (2/183)
A 68-year-old female developed contralateral deafness following extirpation of a left cerebellopontine angle epidermoid cyst. Computed tomography showed that large vestibular aqueduct was present. This unusual complication may have been caused by an abrupt pressure change after cerebrospinal fluid release, which was transmitted through the large vestibular aqueduct and resulted in cochlear damage. (+info)Primary intracranial squamous cell carcinoma--case report. (3/183)
A 50-year-old female presented with primary intracranial squamous cell carcinoma (SCC) at the right cerebellopontine angle manifesting as right facial nerve paresis. She had undergone gross total removal of a right cerebellopontine angle epidermoid cyst 10 years before and had done well until recently. Magnetic resonance imaging showed a heterogeneous tumor with markedly enhanced irregular margin. Subtotal removal of the tumor was achieved. Histological examination showed moderately differentiated SCC. After surgery, she underwent chemotherapy and gamma radiosurgery. She is now well 5 years after the diagnosis of SCC. (+info)Unusual sonographic appearance of an epidermoid cyst of the testis. (4/183)
Epidermoid cyst of the testis is a rare benign testicular tumor with varied sonographic appearances. We present a case in which two specific ultrasonographic patterns were seen: (1) an "onion ring" configuration of alternating hyperechoic and hypoechoic regions, described previously as being characteristic of this lesion, and (2) a heterogeneous region with multiple punctate hyperechoic foci. (+info)Epidermoid tumor within Meckel's cave--case report. (5/183)
A rare case of an epidermoid tumor lying within Meckel's cave is reported. A 27-year-old housewife presented with complaints of right facial hypesthesia for two and a half years. On examination she had partial loss of touch sensation in the right trigeminal nerve distribution. Magnetic resonance imaging revealed a tumor located at the right petrous apex and cavernous sinus. The epidermoid tumor was excised through a lateral basal subtemporal approach. The symptoms resolved following surgery. (+info)Intramedullary spinal epidermoid cyst. (6/183)
Intramedullary epidermoid cysts of the spinal cord are rare tumours, especially those not associated with spinal dysraphism. Around 50 cases have been reported in the literature. Of these, only seven cases have had magnetic resonance imaging studies. We report two cases of spinal intramedullary epidermoid cysts with MR imaging. Both were not associated with spina bifida. In one patient the tumour was located at D4 vertebral level, while in other within the conus medullaris. The clinical features, MR imaging characteristics and surgical treatment of such rare intramedullary benign tumours are discussed, and the relevant literature reviewed. (+info)The utility of diffusion-weighted imaging with navigator-echo technique for the diagnosis of spinal epidermoid cysts. (7/183)
We report a case of a spinal epidermoid cyst in which diffusion-weighted imaging with a navigator-echo technique was useful for the differential diagnosis from other cystic tumors. Motion artifacts are inherent on diffusion-weighted images of the spinal region; however, the navigator-echo technique compensated for this problem and provided high-quality images. Diffusion-weighted imaging with navigator echoes is considered to be a potentially useful tool in the differential diagnosis of spinal cystic tumors. (+info)Hyperdense intracranial epidermoid: an uncommon presentation. (8/183)
A thirty year old female presented with sudden onset of severe headache, papilloedema and altered sensorium. Computerised tomography (CT) scan showed a hyperdense vermian mass in the posterior fossa. Operative findings and histological examination revealed spontaneous bleed into the epidermoid cyst. Difficulty in the preoperative diagnosis and uncommon presentation of the intracranial epidermoid cyst prompted us to report this case. (+info)An epidermal cyst is a common benign skin condition characterized by the growth of a sac-like structure filled with keratin, a protein found in the outermost layer of the skin (epidermis). These cysts typically appear as round, firm bumps just under the surface of the skin, often on the face, neck, trunk, or scalp. They can vary in size from a few millimeters to several centimeters in diameter.
Epidermal cysts usually develop as a result of the accumulation of dead skin cells that become trapped within a hair follicle or a pilosebaceous unit (a structure that contains a hair follicle and an oil gland). The keratin produced by the skin cells then collects inside the sac, causing it to expand gradually.
These cysts are generally slow-growing, painless, and rarely cause any symptoms. However, they may become infected or inflamed, leading to redness, tenderness, pain, or pus formation. In such cases, medical attention might be necessary to drain the cyst or administer antibiotics to treat the infection.
Epidermal cysts can be removed surgically if they cause cosmetic concerns or become frequently infected. The procedure typically involves making an incision in the skin and removing the entire sac along with its contents to prevent recurrence.
Neoplasms are abnormal growths of cells or tissues in the body that can be benign (non-cancerous) or malignant (cancerous). When referring to "Complex and Mixed Neoplasms," it is typically used in the context of histopathology, where it describes tumors with a mixture of different types of cells or growth patterns.
A complex neoplasm usually contains areas with various architectural patterns, cell types, or both, making its classification challenging. It may require extensive sampling and careful examination to determine its nature and behavior. These neoplasms can be either benign or malignant, depending on the specific characteristics of the tumor cells and their growth pattern.
A mixed neoplasm, on the other hand, is a tumor that contains more than one type of cell or tissue component, often arising from different germ layers (the three primary layers of embryonic development: ectoderm, mesoderm, and endoderm). A common example of a mixed neoplasm is a teratoma, which can contain tissues derived from all three germ layers, such as skin, hair, teeth, bone, and muscle. Mixed neoplasms can also be benign or malignant, depending on the specific components of the tumor.
It's important to note that the classification and behavior of complex and mixed neoplasms can vary significantly based on their location in the body, cellular composition, and other factors. Accurate diagnosis typically requires a thorough examination by an experienced pathologist and may involve additional tests, such as immunohistochemistry or molecular analysis, to determine the appropriate treatment and management strategies.
Pilomatrixoma is a benign skin tumor that originates from the hair follicle's matrix. It is also known as calcifying epithelioma of Malherbe. This slow-growing tumor typically appears as a hard, mobile, small nodule, often on the head or neck region. Pilomatrixomas are usually painless but can become inflamed or infected. They are more common in children and young adults and are slightly more prevalent in females than males. Histologically, pilomatrixoma is characterized by the presence of shadow cells, basaloid cells, and calcifications. Surgical excision is the standard treatment for this condition.
Foot dermatoses refer to various skin conditions that affect the feet. These can include inflammatory conditions like eczema and psoriasis, infectious diseases such as athlete's foot (tinea pedis), fungal infections, bacterial infections, viral infections (like plantar warts caused by HPV), and autoimmune blistering disorders. Additionally, contact dermatitis from irritants or allergens can also affect the feet. Proper diagnosis is essential to determine the best course of treatment for each specific condition.
A cyst is a closed sac, having a distinct membrane and division between the sac and its surrounding tissue, that contains fluid, air, or semisolid material. Cysts can occur in various parts of the body, including the skin, internal organs, and bones. They can be caused by various factors, such as infection, genetic predisposition, or blockage of a duct or gland. Some cysts may cause symptoms, such as pain or discomfort, while others may not cause any symptoms at all. Treatment for cysts depends on the type and location of the cyst, as well as whether it is causing any problems. Some cysts may go away on their own, while others may need to be drained or removed through a surgical procedure.
Acneiform eruptions refer to skin conditions that resemble or mimic the appearance of acne vulgaris. These eruptions are characterized by the presence of papules, pustules, and comedones on the skin. However, acneiform eruptions are not true acne and can be caused by various factors such as medications, infections, or underlying medical conditions.
Some examples of acneiform eruptions include:
* Drug-induced acne: Certain medications such as corticosteroids, lithium, and antiepileptic drugs can cause an acne-like rash as a side effect.
* Rosacea: A chronic skin condition that causes redness, flushing, and pimple-like bumps on the face.
* Pseudofolliculitis barbae: A condition that occurs when curly hair grows back into the skin after shaving, causing inflammation and acne-like lesions.
* Gram-negative folliculitis: A bacterial infection that can occur as a complication of long-term antibiotic use for acne treatment.
It is important to distinguish acneiform eruptions from true acne vulgaris, as the treatment approach may differ depending on the underlying cause. Dermatologists or healthcare providers specializing in skin conditions can provide an accurate diagnosis and recommend appropriate treatment options.
Molluscum contagiosum is a viral skin infection that results in small, round, painless, and pearly or flesh-colored bumps on the skin. These bumps have a dimple in the center and can appear anywhere on the body but are most commonly found in warm, moist areas such as the armpits, behind the knees, and in the groin area. The virus that causes molluscum contagiosum is called the Molluscum contagiosum virus (MCV) and is part of the poxvirus family.
The infection spreads through direct contact with an infected person or through contact with contaminated objects such as towels, clothing, or toys. It can also be transmitted through sexual contact, making it a common sexually transmitted infection (STI) in adults. The incubation period for molluscum contagiosum ranges from two weeks to six months, and the bumps typically appear 2-7 weeks after exposure.
Molluscum contagiosum is generally a self-limiting condition that resolves on its own within 6-12 months without scarring. However, treatment may be recommended for cosmetic reasons or to prevent the spread of infection. Treatment options include cryotherapy (freezing the bumps with liquid nitrogen), curettage (scrapping off the bumps), topical medications, and laser therapy.
Preventive measures such as good hygiene practices, avoiding sharing personal items, covering lesions, and practicing safe sex can help prevent the spread of molluscum contagiosum.
Steatocystoma Multiplex is a rare genetic skin condition characterized by the development of multiple sebaceous (oil-producing) cysts called steatocystomas. These cysts typically appear as small, firm, dome-shaped bumps or nodules under the skin, ranging in size from a few millimeters to several centimeters in diameter. They are filled with an oily, yellowish material and may be found anywhere on the body, but they most commonly occur on the chest, back, and upper arms.
Steatocystomas usually appear during adolescence or early adulthood, although they can develop at any age. The cysts may become inflamed, infected, or rupture, causing pain, redness, and swelling. In some cases, they may also release an oily, foul-smelling discharge.
Steatocystoma Multiplex is caused by a genetic mutation that affects the development of sebaceous glands. It is inherited in an autosomal dominant manner, meaning that a person has a 50% chance of developing the condition if one of their parents has it. Treatment options for Steatocystoma Multiplex include surgical removal of the cysts, laser therapy, and oral medications such as isotretinoin to reduce the size and number of cysts. However, these treatments may not be effective in preventing new cysts from developing.
Hair diseases is a broad term that refers to various medical conditions affecting the hair shaft, follicle, or scalp. These conditions can be categorized into several types, including:
1. Hair shaft abnormalities: These are conditions that affect the structure and growth of the hair shaft. Examples include trichorrhexis nodosa, where the hair becomes weak and breaks easily, and pili torti, where the hair shaft is twisted and appears sparse and fragile.
2. Hair follicle disorders: These are conditions that affect the hair follicles, leading to hair loss or abnormal growth patterns. Examples include alopecia areata, an autoimmune disorder that causes patchy hair loss, and androgenetic alopecia, a genetic condition that leads to pattern baldness in both men and women.
3. Scalp disorders: These are conditions that affect the scalp, leading to symptoms such as itching, redness, scaling, or pain. Examples include seborrheic dermatitis, psoriasis, and tinea capitis (ringworm of the scalp).
4. Hair cycle abnormalities: These are conditions that affect the normal growth cycle of the hair, leading to excessive shedding or thinning. Examples include telogen effluvium, where a large number of hairs enter the resting phase and fall out, and anagen effluvium, which is typically caused by chemotherapy or radiation therapy.
5. Infectious diseases: Hair follicles can become infected with various bacteria, viruses, or fungi, leading to conditions such as folliculitis, furunculosis, and kerion.
6. Genetic disorders: Some genetic disorders can affect the hair, such as Menkes syndrome, which is a rare inherited disorder that affects copper metabolism and leads to kinky, sparse, and brittle hair.
Proper diagnosis and treatment of hair diseases require consultation with a healthcare professional, often a dermatologist or a trichologist who specializes in hair and scalp disorders.
Molluscum contagiosum (MCV) is a DNA poxvirus that causes a common, benign, and generally self-limited skin infection known as molluscum contagiosum. This viral infection results in small, raised, pearly or flesh-colored bumps or papules on the skin. The lesions typically have a dimple or pit in the center and can appear anywhere on the body, but they are most commonly found in warm, moist areas such as the armpits, behind the knees, and in the groin area.
MCV is highly contagious and can spread through direct skin-to-skin contact, including sexual contact, or through contact with contaminated objects like towels or clothing. It is more common in children than adults, but in sexually active individuals, it often presents as a genital infection. The incubation period for MCV ranges from two weeks to several months, and the infection usually resolves on its own within 6-12 months, although treatment may be considered to expedite clearance or reduce transmission risk.
Acne vulgaris is a common skin condition characterized by the formation of various types of blemishes on the skin, such as blackheads, whiteheads, papules, pustules, and cysts or nodules. These lesions typically appear on areas of the body that have a high concentration of sebaceous glands, including the face, neck, chest, back, and shoulders.
Acne vulgaris occurs when hair follicles become clogged with dead skin cells and excess oil (sebum) produced by the sebaceous glands. This blockage provides an ideal environment for bacteria, particularly Propionibacterium acnes, to multiply, leading to inflammation and infection. The severity of acne vulgaris can range from mild with only a few scattered comedones (blackheads or whiteheads) to severe cystic acne, which can cause significant scarring and emotional distress.
The exact causes of acne vulgaris are not fully understood, but several factors contribute to its development, including:
1. Hormonal changes during puberty, menstruation, pregnancy, or due to conditions like polycystic ovary syndrome (PCOS)
2. Genetic predisposition
3. Use of certain medications, such as corticosteroids and lithium
4. Excessive production of sebum due to overactive sebaceous glands
5. Accumulation of dead skin cells that clog pores
6. Bacterial infection (particularly Propionibacterium acnes)
7. Inflammation caused by the body's immune response to bacterial infection and clogged pores
Treatment for acne vulgaris depends on its severity and can include over-the-counter or prescription topical treatments, oral medications, chemical peels, light therapies, or even hormonal therapies in some cases. It is essential to seek professional medical advice from a dermatologist or healthcare provider to determine the most appropriate treatment plan for individual needs.

- Oxidative and nitrosative stress caused by drug metabolism may be a trigger for keratinocyte apoptosis in the epidermis seen in toxic epidermal necrolysis (TEN) and Stevens Johnson syndrome (SJS). (e-ijd.org)
Lipomas1
- Cysts are in general benign, but in some cases, if associated with fibromas or lipomas of the skin, may fall into the category of being premalignant. (healthandnutritiontips.net)
Hair follicles2
- Vulvar epidermal cysts are similar but contain secretions from oil-producing (sebaceous) glands near hair follicles. (msdmanuals.com)
- Most of the time the cyst simply pushes against the wall of one or more hair follicles, and when this happens hair will not emerge. (healthandnutritiontips.net)
Clinically1
- The entity can also be clinically similar to a common epidermal cyst ( Fig. 2 ). (lww.com)
Terminal phalanx2

Skin8
- Pigmentation of epidermoid cysts is common in individuals with dark skin. (medscape.com)
- The cysts are tiny, hard masses which form underneath the skin. (simple-remedies.com)
- The cysts are formed when elements of the surface skin get under the skin surface. (medlineplus.gov)
- The cyst then becomes filled with dead skin because as the skin grows, it can't be shed as it can elsewhere on the body. (medlineplus.gov)
- 1 The only other possible complication is local infection following traumatic rupture of the cyst or disruption of the overlying skin. (aafp.org)
- Imagine the feeling of a large pea growing under your skin and you can understand what a cyst feels like. (midwestderm.com)
- But, instead, a small sac forms under the skin and fills up with dead cells, as well as pus or liquid, and voila, you've got a cyst! (midwestderm.com)
- This is often a temporary solution because the cyst sac remains in the skin. (midwestderm.com)
Neck1
- Branchial cleft cysts are found in the neck and do not usually cause problems unless they become infected. (healthlinkbc.ca)
Steatocystoma1
- A true sebaceous cyst is called a steatocystoma. (medlineplus.gov)
Penile3
- Here, we introduce an extremely rare case of a penile epidermal cyst causing penile distortion. (jwmr.org)
- Nevertheless, penile epidermal cysts are relatively rare [ 1 , 2 ]. (jwmr.org)
- This report presents an extremely rare case of a large epidermal cyst causing penile distortion that occurred years after augmentation penoplasty with dermal fat graft. (jwmr.org)
Antibiotics2
- Your health care provider will prescribe antibiotics and drainage of the cyst. (simple-remedies.com)
- In those instances where a cyst has become inflamed or infected, a doctor will usually treat it with antibiotics and wait for the condition to subside before attempting to remove the cyst, to avoid spreading of the infection. (healthandnutritiontips.net)
Carcinoma4
- In a series of epidermoid cysts with carcinoma, immunohistochemical results for HPV were negative, suggesting that HPV is not likely to play a role in the development in squamous cell carcinoma (SCC) in epidermoid cysts. (medscape.com)

- Epidermoid cysts are very common. (medlineplus.gov)
- These cysts are more common in adults than in children. (medlineplus.gov)
- Ganglion cysts are common and can arise from various joints and tendons, but they most often affect the wrists and fingers. (aafp.org)
- Ganglion cysts are most common in women younger than 40 years. (aafp.org)

Trauma1
- If epithelium remains enclosed during wound healing after trauma or surgery, keratinization occurs and leads to cyst formation [ 3 ]. (jwmr.org)
Ganglion2
Infection1
- Squeezing out the contents of the cyst on your own can lead to infection, so leave the cyst well alone or discuss with your doctor. (simple-remedies.com)
Symptoms3
- Cysts that do not become infected usually cause no symptoms, but they occasionally cause irritation. (msdmanuals.com)
- If cysts cause symptoms, they are removed. (msdmanuals.com)
- If a cyst is not causing symptoms, treatment may not be necessary. (medicalnewstoday.com)

- Based on the clinical, radiographic and histopathological features, the cyst was diagnosed as orthokeratinized odontogenic cyst. (bvsalud.org)
Unclear1
- The manner in which carcinomas may arise within epidermoid cysts is unclear. (medscape.com)
Squeezing1
- Attempting the remove the cyst by squeezing it is more often than not an exercise in futility, as the cyst contains a sac, and unless the sac is removed, the cyst will most likely return. (healthandnutritiontips.net)
