Nevus lipomatosus superficialis is an uncommon beningn hamartomatous skin lesion. The classic type of NLCS is usually unilateral as seen in our case. The classic variety of NLCS is either present at birth or can arise at any other time within in Ist two decades of life4,5,6. There are sporadic case reports of coexistent anomalies in the form of café-au-lait macules and scattered leucoderma. Increased hairness and comedo-like lesions have also been reported7. The histopathology of NLCS usually shows a normal or slightly attenuated epidermis associated with dermal proliferation of mature adipocytes in the reticular dermis that may extend to papillary dermis . The adipocytes most commonly form small aggregates around blood vessels or eccrine glands, but may also be present as solitary adipocytes between collagen bundles. …show more content…
The adipocytes may show conection to the underlying subcutaneous fat or be separated from the subcutis by collagen .Less commonly ,spindle cells representing immature fat cells may also be present. NLCS should be differentiated from nevus sebaceous, skintags, neurofibroma, lymphangioma and focal dermal hypoplasia (Goltz syndrome). Histopathological examination usually helps in the differentiation. No fat cells are present in the dermis in the case of skin tags. Simillar dermal collections of adipocytes on histopathological examination are also present in some melanocytic nevi,pedunculated lipofibromas and in Goltz syndrome. Lipofibromas contain fat cells, but no skin appendages in the dermis. In the case of Goltz syndrome, there is absence of collagen in the atrophic dermis and skin appendages are absent. The precise etiopathogenesis of NLCS is not
NO THANKSUSE THE APP Lupus Essay-Human Anatomy Le Linh Le Professor D. Henry Human Anatomy November 16, 2015 Systemic Lupus Erythematosus Systemic Lupus Erythematosus, better known as “Lupus,” is a chronic autoimmune disorder where the body’s immune system becomes uncontrollable. Patients with Lupus would have their immune system attack their healthy tissues instead of attacking bacteria and viruses like it would in a healthy functioning body. This can cause damages to various parts of the body such as the skin, kidneys, joints, blood, and brain.
Non-segmental vitiligo is the most common form of vitiligo. It is also referred to as Bilateral vitiligo, Vitiligo vulgaris and Generalized vitiligo7. 90%6 of the people who have vitiligo have non-segmental vitiligo. Non-segmental vitiligo is characterised by the non-pigmented patches of skin that are visibly symmetrical8 on both sides of the body, these patches increase in size over time. The most common places were non-segmental vitiligo appears is on skin that is exposed daily to the sun, such as the face, neck, and hands, backs of the hands, arms, eyes, knees, elbows, feet and the mouth.
The causes of vitiligo are uncertain; however it is believed to be an autoimmune disease, in other words, the body essentially attacks its’ own self. It is thought that the immune system attacks the melanocytes, or that the melanocytes destroy other melanocytes, leading to the depigmentation we see with vitiligo (National Institute of Health, 2014). It is also possible that vitiligo is passed down genetically; however it has yet to be proven. While the pathophysiology of vitiligo has yet to be defined as definite, patterns and trends have been observed. For instance, those with vitiligo are thought to be at a higher risk for other autoimmune diseases such as thyroid disease and type I diabetes mellitus because high levels of anti-TPO antibodies have been seen in both individuals with thyroid disease as well as vitiligo (Gude, 2012).
8. Oil folliculitis is inflammation of hair follicles due to exposure to various oils and typically occurs on forearms or thighs. It is common in refinery workers, road workers, mechanics, and sheep shearers. Other causes include • Friction from clothing, • an insect bite, • blockage of the follicle, • shaving • Bathing in infected bath
This neck gland is butterfly-shaped, but it is normally not visible to the naked eye. It is also responsible for producing hormones that help regulate body metabolism. Hurthle cell cancer, also called oxyphilic cell carcinoma is a rare condition,
One million people in the U.S are diagnosed each year with some types of skin cancer. There are three major types of skin cancer, basal cell carcinoma, squamous cell carcinoma, and of course melanoma. Most people are more familiar with melanoma and because it is the least common they continue to think they won’t get cancer. The majority of skin cancer cases are basal cell carcinomas and squamous cells carcinomas. They are malignant meaning they will not spread to other parts of the body, and are usually able to be easily removed.
Morgellons Disease is an uncommon skin disorder. There are sores on the skin with crawling sensations of the skin and fiber-like filaments coming from the sores. Some have rashes, severe fatigue, difficulty concentrating and short term memory loss. (MC) The CDC claim they did not find a single underlying medical condition or infectious source.
These lesions expand to form ulcers and extensive erosions filled with necrotic tissue and mycelium. This is followed by the development of granulomas on the internal organs and eventually
Skin cancer The name of this disease is called Skin cancer. It's a type of skin tumor that is characterized by the cancerous growth of melanocytes. This is what causes the cells to produce a dark pigment called melanin. Anyone can get skin cancer.
Psoriasis A long term chronic skin disease which causes skin cells to grow too rapidly is known as Psoriasis. The results are thick silvery, white, or red patches to appear on the surface of the skin. Areas affected are generally the elbows, knees, scalp, back, palms, face, and feet. According to the American Academy of Dermatology, it’s estimated that about 7 million people in the United States alone are suffering from the skin disease, a vast majority being Caucasians.
It may result in psychological and social problems some of the large nodules were previously called cysts and the term nodulocystic has been used to describe severe cases of inflammatory acne (Devid et al., 2003). Scars Acne scars are the result of inflammation within the dermal layer of skin brought on by acne and are estimated to affect 95% of people with acne vulgaris. The scar is created by an abnormal form of healing following this dermal inflammation. Scarring is most likely to occur with severe nodulocystic acne, but may occur with any form of acne vulgaris.
These patches are common in areas of the skin in which it is exposed to the sun more. It may be on the hands, feet, face, arms and lips. The patches of white skin will often have hair that turns grey early in those areas. Those with dark skin may also notice a loss of color inside their mouths. There is no way of knowing or being able to tell how much these patches of white skin will spread.
There are different types of skin cancers which include Actinic keratoses, Basal cell carcinoma, Squamous cell carcinoma, Melanoma cancer, and Merkel cell carcinoma. Actinic keratoses (AK): These are dry, scaly patches or spots that are precancerous growths. They occur in people who usually have fair skin color. Most Actinic keratoses patients develop their first cancer after 40 years of age because Actinic keratosis tends to develop after years of sun exposure. It usually develops on the skin that gets lots of sun exposure like the head, neck, hands, and forearms.
Pigmentation does not extend deeper than the lamina propria. Usually, Prussian blue and long Ziehl-Neelsen stains are negative, confirming that the pigmented granules are neither hemosiderin nor lipofuscin. These features support the notion that the granules are indeed melanin
It forms on places of the skin most exposed to the sun. For example the legs, arm, and face. This cancer mainly forms on light skinned individuals, but can also form on dark
