Уже давно доказано, что с возрастом замедляется обмен веществ. Особенно остро эта проблема проявляется после 35 лет. Но что же делать женщинам, которые всегда хотят выглядеть безупречно? Оказывается, для того, чтобы восстановить обмен веществ, нужно придерживаться определенных правил. Дело в том, что процессы старения запускаются в организме, когда нарушается работа эндокринной системы. Чтобы наладить обмен веществ, необходимо вести […]

Pilar Cyst (Trichilemmal Cyst) Pilar cysts are relatively common benign growths that occur most frequently on the scalp. They go by many names, including wen, trichilemmal cyst, and isthmuscatagen cyst. Most are solitary, but it is not uncommon to see multiple pilar cysts in a single individual. Their appearance is similar to that of epidermal inclusion cysts, but the pathogenesis is completely different. There is a malignant counterpart called a metastasizing proliferating trichilemmal cyst. The malignant trans- formation of a pilar cyst is exceedingly rare. Subsets of these growths are inherited. Clinical Findings: Pilar cysts occur most frequently on the scalp. They can be mistaken for epidermal inclusion cysts. The main clinical differentiating points are that pilar cysts do not have an overlying central punctum, and they tend to be a bit firmer to touch. These cysts occur more commonly in adults, and they have a tendency to affect women more often than men. They typically manifest as slowly growing, firm dermal nodules with no overlying epidermal changes and no central punctum. These cysts do not drain, as epidermal cysts sometimes do. They also rarely get inflamed. Almost exclusively found in the scalp, they are for the most part asymptomatic. Patients present to the clinician because of an enlarging nodule. As opposed to the epidermal inclusion cyst, which essentially has no malignant potential, the pilar cyst does have a small proliferating and malignant potential. This risk is very low. Some families show an autosomal dominant inheritance pattern. The exact gene defect has yet to be determined, but a possible gene has been mapped to chromosome 3. Most patients with the hereditary version of this condition have solitary lesions. Numerous lesions are infrequently encountered in the inherited form. Pathogenesis: Pilar cysts are also called trichilemmal cysts, because they are derived from the outer root sheath of the hair follicle, which undergoes trichilemmal keratinization. This form of keratinization is unique in that there is no granular layer. The hereditary version of this disease was originally thought to be caused by a defect in the gene encoding β-catenin. This has been disproven, and the familial gene has been mapped to the short arm of chromosome 3, although the exact genetic defect has yet to be elucidated. These cysts are believed to be derived from the isthmus of anagen-type hairs. They are formed from deeper elements of the hair shaft apparatus than the epidermal inclusion cyst are. Histology: Pilar cysts are composed of compact layers of stratified squamous epithelium without a granular cell layer. The cysts are found within the dermis, and the overlying epidermis is unaffected. These cysts show an absence of intercellular adhesion molecules. The cysts can become calcified or ossified. The cysts have a unique peripheral rim of keratinocyte nuclei, which is very helpful in classifying them. The central aspect of the cyst contains homogenous pale, eosinophilic, compressed keratin. Treatment: Simple surgical excision is curative. The recurrence rate is minimal. These cysts typically are removed very easily after excision through the overlying skin into the cyst wall. The cyst almost always “pops” out with slight lateral pressure, and only a small incision is needed. After removal, care needs to be taken to decrease the amount of dead space left, to avoid seroma formation. This can be prevented by removing some of the redundant overlying epidermis and suturing the deeper tiss es together to close the space left by the removed cyst.

ECCRINE SYRINGOMA Eccrine syringomas are extremely common benign skin growths. They are most often found on the lower eyelids and malar cheek regions of adults. These small tumors are of no clinical significance and are routinely ignored in clinical practice. Clinical Findings: Eccrine syringomas are some of the most common benign skin tumors to affect human- kind. They are believed to be more common in women than in men. They typically manifest in adulthood as flesh-colored, small (2-4 mm) papules on the lower eyelids or upper cheek regions. They are usually multiple and symmetric. Some have a slight yellow or tan hue. Other areas of the body on which syringomas are seen include the upper eyelids, neck, and chest. They have been reported to occur on any region of the body. Plaque-like syringomas have been reported to occur on the forehead, and they have the appearance of a flesh-colored to slightly yellow, broad, flat plaque with minimal to no surface change. They can be quite large, up to 4 to 5 cm in diameter. They are essentially asymptomatic, but occasionally a patient complains of slight intermittent itching or of an increase in size with strenuous physical activity. This is possibly explained by the eccrine nature of the tumors: Under conditions of activity, an increase in sweating causes the tumors to transiently appear to enlarge. There are specific variants seen in patients with diabetes mellitus and in those with Down syndrome. A form of eruptive syringoma has been described that typically afflicts the anterior trunk and the penile shaft. Linear syringomas have been reported to occur on a unilateral limb, and these have been termed unilateral linear nevoidal syringomas. The clinical differential diagnosis of eccrine syringomas is relatively limited when the clinician encounters symmetric small papules on the lower eyelids. The differential diagnosis for a solitary syringoma is broad and includes other adnexal tumors as well as basal cell carcinoma. The most difficulty arises when reviewing the histological features of a syringoma that has been biopsied in a superficial manner. If the pathologist is not given a thick enough specimen, the eccrine syringoma can mimic a microcystic adnexal carcinoma. These two tumors, one benign and the other malignant, can have very similar histological features in the superficial dermis. In some cases, it is only with a full-thickness biopsy that a pathologist can confidently differentiate the two tumors. Histology: The overlying epidermis is normal. The tumor is based within the dermis and is sharply circumscribed. The syringoma typically does not penetrate deeper than the upper third of the dermis. Clusters of cells with a pale cytoplasm are found throughout the tumor. A background of sclerotic stromal tissue is always appreciated. A characteristic finding is the “tadpole” sign. The tadpoleor comma-shaped, dilated ductal eccrine gland apparatus is pathognomonic for eccrine syringoma. Clear cell variants are associated with diabetes mellitus. A microcystic adnexal carcinoma is poorly circumscribed, is asymmetric, and infiltrates into the underlying subcutis. Pathogenesis: Eccrine syringomas are believed to be an overgrowth of the eccrine sweat ductal apparatus. Researchers have proposed that this proliferation is caused by an inflammatory response to an as yet undetermined antigen. The precise pathogenesis of eccrine syringomas is unclear. Familial patterns suggest a genetic predisposition, but most patients do not have a family history to support genetic transmission. Treatment: No treatment is necessary. If one wishes to pursue therapy, it should be done with caution, because treatment experiences are anecdotal, and scarring may have a worse appearance than the syringoma itself. Electrocautery, light cryotherapy, chemical peels, laser resurfacing, dermabrasion, and excision have been reported with variable results.
Весна - хорошее время для начала чего-то нового. Ровно 3 года назад, весной 2017 появилась моя первая кукла. Я не знала как и из чего её сделать, перед глазами были только невероятные работы уже известных мастеров. И начались ежедневные эксперименты, поиски решений, ошибки, первые смешные полуфабрикаты, и наконец появилась ОНА! Из шерсти и ткани, с милой такой мордашкой. С той поры родились разные куклы, большие, средние и совсем маленькие (на ёлку), от текстильных я перешла к лепным. (фото все внутри). А этой весной снова вернулась к мягкой кукле, но с новой идеей..
