Papillomas on the eyelid are benign tumor-like growths of the epithelial coverings of the skin, sitting on a stalk. on a wide base.
Papilloma (syn. fibroepithelial polyp) is a benign tumor histogenetically associated with the epidermis, can occur at any age, but more often in older people.
Pedunculated conjunctival papilloma manifestations may be early, after birth, or years later. Papillomas, which may be numerous and sometimes bilateral, are most often located on the palpebral conjunctiva, fornix, or caruncle.
Acanthosis nigricans (papillary-pigmented skin dystrophy) is characterized by hyperkeratosis, hyperpigmentation and papillomatosis of the skin, armpits and other large folds.
Papillary syringoadenoma (syn.: papillary eccrine adenoma, papillary syringocystadenoma, papillary syringocystadenomatous nevus; papillary tubular adenoma is a rare tumor, localized more often on the skin of the distal parts of the extremities in the form of a clearly demarcated hemispherical nodule, sometimes with a semi-translucent wall, 0.5-1.5 cm in diameter.
Hidradenoma papillae is a benign tumor of the apocrine sweat glands. The causes and pathogenesis of hidradenoma papillae of the skin are unknown.
The causes and pathogenesis of spontaneous panniculitis have not been fully studied. Past infections, trauma, drug intolerance, pancreatic lesions, etc. are of great importance. Lipid peroxidation processes play a certain role.
The main symptom of panic disorder is recurrent panic attacks. Panic attacks are characterized by sudden intense anxiety, accompanied by at least four vegetative or cognitive symptoms. Panic attacks tend to develop rapidly, with anxiety reaching a climax within a few minutes.
Panic disorder occurs when a child has recurrent, frequent (at least once a week) panic attacks. Panic attacks are discrete episodes, lasting approximately 20 minutes, during which the child develops somatic or psychological symptoms. Panic disorder may develop with or without agoraphobia.
A panic attack is a sudden, brief attack of intense discomfort or fear, accompanied by somatic or cognitive symptoms.
This concept includes hypothalamic-pituitary insufficiency, postpartum hypopituitarism - Sheehan's syndrome, pituitary cachexia - Simmonds' disease. In 1974, M. Simmonds described postpartum, septic-embolic necrosis of the anterior pituitary gland with a fatal outcome in a state of severe cachexia and catastrophically developed senile involution of organs and tissues.
Most often, acute pancreatitis occurs in old age and less often in old age with increased pressure in the pancreatic ducts, which leads to damage to the acinar cells and their membranes with the release of pancreatic enzymes into the parenchyma, interlobular connective and adipose tissue of the pancreas.
Pancreatitis is an inflammation of the pancreas. There are two main forms - acute and chronic pancreatitis.
In most cases, they are found in the intestine in the ileocecal angle and in the bronchi, but are rarely functional. Pancreatic carcinoid is capable of secreting almost all peptides characteristic of ortho- and paraendocrine neoplasms.
Tuberculous lesions of the pancreas are very rare, even in patients with active pulmonary tuberculosis it is detected, according to various authors, only in 0.5-2% of cases. Tuberculous mycobacteria enter the pancreas by hematogenous, lymphogenous or contact (from affected neighboring organs) routes.
Syphilis of the pancreas can be congenital and acquired. It is believed that specific damage to the pancreas is found in almost 10-20% of children suffering from congenital syphilis; the head of the pancreas is most often affected. Syphilitic changes in the pancreas are detected in the fetus already in the second half of pregnancy.
Stones in the pancreas were first discovered in 1667 by Graaf. Subsequently, individual observations of pancreolithiasis began to accumulate, and according to autopsy data, its frequency fluctuates between 0.004 and 0.75% of cases.
Pancreatic sarcoma is extremely rare; to date, about 200 cases of pancreatic sarcoma have been described in specialized medical literature (according to the combined statistics of a number of authors).
Pancreatic fistula, also known as pancreatic fistula, is an uncommon pathologic condition in which a communication or channel is formed between the pancreas and neighboring organs or structures.
Usually, according to their origin and morphological features, four types of pancreatic cysts are distinguished. The first type is ontogenetic cysts, which are a developmental defect; such cysts are often multiple and often combined with polycystic disease of other organs (lungs, kidneys, liver, etc.), thus representing congenital polycystic disease. Cysts are usually lined inside with a single-row cubic epithelium, and their contents are serous and do not contain enzymes.
