Hidradenitis Suppurativa
A chronic suppurative and cicatricial disease of the apocrine glands occurring chiefly in the axillae in women and in the groin and anal regions in men. It is characterized by poral occlusion with secondary bacterial infection, evolving into abscesses which eventually rupture. As the disease becomes chronic, ulcers appear, sinus tracts enlarge, fistulas develop, and fibrosis and scarring become evident.
Paget Disease, Extramammary
A rare cutaneous neoplasm that occurs in the elderly. It develops more frequently in women and predominantly involves apocrine gland-bearing areas, especially the vulva, scrotum, and perianal areas. The lesions develop as erythematous scaly patches that progress to crusted, pruritic, erythematous plaques. The clinical differential diagnosis includes squamous cell carcinoma in situ and superficial fungal infection. It is generally thought to be an adenocarcinoma of the epidermis, from which it extends into the contiguous epithelium of hair follicles and eccrine sweat ducts.

Submandibular Gland
One of two salivary glands in the neck, located in the space bound by the two bellies of the digastric muscle and the angle of the mandible. It discharges through the submandibular duct. The secretory units are predominantly serous although a few mucous alveoli, some with serous demilunes, occur. (Stedman, 25th ed)
Immunohistochemical analysis of Ki-67, p53, p21, and p27 in benign and malignant apocrine lesions of the breast: its correlation to histologic findings in 43 cases. (1/80)
We examined Ki-67, p53, p21, and p27 immunolocalization in 43 cases of apocrine lesions of the breast and correlated these findings with histologic parameters to understand their biologic significance. Twenty cases were benign, 1 case was borderline, and 22 cases were diagnosed as malignant, including 9 intraductal and 13 invasive apocrine carcinomas. Both the ratio of Ki-67-positive cases (17 of 21 [88.9%] versus 1 of 19 [5.3%]; P < .001) and the Ki-67 labeling index of positive cases examined (15.0% versus 2.7%; P < .005) were significantly higher in malignant than in benign apocrine lesions. None of the benign or borderline cases was immunohistochemically positive for p53, but 15 of 22 malignant cases (68.2%) demonstrated p53 (P < .001). In addition, the ratio of p53-positive cases was significantly higher in high nuclear grade cases (11 of 13 [84.6%]) than in intermediate nuclear grade cases (4 of 9 [44.4%]; P < .05). P53 immunoreactivity was also positively correlated with the nuclear grade of carcinoma cases examined in this study. Neither p21 nor p27 demonstrated any correlation with histologic parameters or findings of the apocrine lesions. Results of these studies suggest that Ki-67 and p53 may be good markers for differentiation between benign and malignant breast apocrine lesions. (+info)Immunohistochemical localisation of androgen receptor in apocrine metaplasia and apocrine adenosis of the breast: relation to oestrogen and progesterone receptors. (2/80)
AIM: To investigate the receptor status of the sex steroid hormones in apocrine metaplasia of the breast. METHODS: 82 cases of apocrine metaplasia, including 18 of the rare lesion apocrine adenosis, were studied immunohistochemically for the expression of androgen receptor, oestrogen receptor, and progesterone receptor proteins on formalin fixed, paraffin embedded tissue sections. The standard avidin biotin complex (ABC) technique was followed and appropriate positive and negative controls were used. RESULTS: All the studied cases (82/82) were positive for androgen receptor, but were negative for oestrogen receptor and progesterone receptor. CONCLUSIONS: Apocrine metaplastic epithelium, unlike the normal breast epithelium, is responsive to androgens, through androgen receptors, rather than to the female sex hormones. This may have clinical implications. (+info)A novel aspartyl proteinase from apocrine epithelia and breast tumors. (3/80)
GCDFP-15 (gross cystic disease fluid protein, 15 kDa) is a secretory marker of apocrine differentiation in breast carcinoma. In human breast cancer cell lines, gene expression is regulated by hormones, including androgens and prolactin. The protein is also known under different names in different body fluids such as gp17 in seminal plasma. GCDFP-15/gp17 is a ligand of CD4 and is a potent inhibitor of T-cell apoptosis induced by sequential CD4/T-cell receptor triggering. We now report that GCDFP-15/gp17 is a protease exhibiting structural properties relating it to the aspartyl proteinase superfamily. Unexpectedly, GCDFP-15/gp17 appears to be related to the retroviral members rather than to the known cellular members of this class. Site-specific mutagenesis of Asp(22) (predicted to be catalytically important for the active site) and pepstatin A inhibition confirmed that the protein is an aspartic-type protease. We also show that, among the substrates tested, GCDFP-15/gp17 is specific for fibronectin. The study of GCDFP-15/gp17-mediated proteolysis may provide a handle to understand phenomena as diverse as mammary tumor progression and fertilization. (+info)Extramammary Paget disease is characterized by the consistent lack of estrogen and progesterone receptors but frequently expresses androgen receptor. (4/80)
Extramammary Paget disease (EPD) is an uncommon cutaneous malignant neoplasm that arises in areas rich in apocrine glands (perineum, vulva, and axilla). Apocrine gland origin or apocrine differentiation of cells of EPD has been suggested. Estrongen, progesterone, and androgen hormone receptors have been reported to exhibit a characteristic pattern of expression in mammary apocrine type carcinomas; however, their expression in EPD has not been elucidated fully. By using immunohistochemical methods, we studied the expression of steroid receptors in EPD on formalin-fixed paraffin-embedded tissue samples from 28 patients with EPD without associated visceral malignant neoplasms or adnexal carcinoma. Androgen receptor (AR) was identified in 15 of 28 cases. The proportion of AR-positive cells varied from 1% to more than 75%; 8 cases expressed AR in more than 10% of cells. Strong AR expression also was seen in the invasive carcinoma arising from 1 case of EPD. All cases lacked immunohistochemically detectable estrogen and progesterone receptors. The immunophenotype characteristic of apocrine carcinomas (AR-positive, estrogen receptor-negative, progesterone receptor-negative) was seen in a substantial proportion of EPD cases. Results suggest that AR expression is a factor in pathogenesis of EPD. This may be important for the therapy of recurrent or invasive disease. (+info)Histo-physiology of the scent-marking glands of the penile pad, anal pouch, and the forefoot in the aardwolf (Proteles cristatus). (5/80)
The scentmarking glands of the anal pouch, penile pad, and the forefoot of the aardwolf (Proteles cristatus) were studied by histological, histochemical, immunohistochemical methods, and by electron microscopy. The morphological observations are correlated with eco-ethological aspects of this nocturnal animal. In all studied regions there was a superficial layer of holocrine sebaceous glands and a deeper layer of apocrine scent glands; these two types of glands apparently function in concert. Only in the forefoot were additional tubular glands, resembling eccrine sweat glands found, which may improve the frictional capacities of the paw, while apocrine and holocrine glands serve scent-marking functions of the forefoot. Penile pad and anal pouch are exclusively scent marking organs. The secretion modus of the apocrine glands is both via exocytosis and apocrine mechanism. Homogeneous apical, secretory granules, which contain glycoproteinaceous material, represent evidence for exocytosis. In the anal pouch, additional variably sized granules contain endogenous pigments which are probably responsible for the brownish coloration of the secretory product of the male animals. Variable heights of the glandular cells, frequent apical tall protrusions as well as pinched-off pieces of cytoplasm in the glandular tubules support the concept of an apocrine secretion in the scent glands. The immunohistochemical staining pattern of actin points to the involvement of actin filaments in the pinching-off process of the apical cell protrusion, which does not contain any cell organelles. The variable actin staining patterns suggest a dynamic process during which actin filaments form a ring or sheet at the basis of the pinching-off bleb. Proliferative and apoptotic phenomena show no preference for active and inactive glandular cells suggesting that replacement of cells occurs independently of the functional status of the glands. (+info)Aspects of general antimicrobial properties of skin secretions in the common seal Phoca vitulina. (6/80)
Considerable amounts of several saccharide residues (alpha-D-Man, beta-D-GlcNAc, alpha-D-GalNAc, beta-D-Gal, alpha-D-Gal, alpha-L-Fuc, NeuNAc) are demonstrated by lectin histochemistry in the sections of the sebaceous glands, and, particularly, the apocrine tubular glands of the common seal. These sugars may be liberated on the skin surface by microbial activities and, then, represent a general antimicrobial protection mechanism of the skin because of their ability to inhibit the adherence of different bacteria and fungi to the epidermis. (+info)Molecular cytogenetic comparison of apocrine hyperplasia and apocrine carcinoma of the breast. (7/80)
The relationship of apocrine metaplasia to invasive breast cancer is controversial. Different authors have reported that apocrine differentiation in proliferative lesions may be a risk factor, a precursor lesion, or have no association with malignancy. The aim of this study was to compare the genetic alterations in benign apocrine hyperplasia with apocrine ductal carcinoma in situ (DCIS) and invasive apocrine carcinomas of the breast using comparative genomic hybridization. The mean number of alterations in apocrine hyperplasia was 4.1 (n = 10) compared to 10.2 in apocrine DCIS (n = 10) and 14.8 (n = 4) in invasive carcinoma. The most common alterations in apocrine hyperplasia were gains of 2q, 13q, and 1p and losses of 1p, 17q, 22q, 2p, 10q, and 16q. Apocrine DCIS and invasive carcinomas showed gains of 1q, 2q, 1p, and losses of 1p, 22q, 17q, 12q, and 16q as their most common DNA copy number changes. Apocrine hyperplasia is considered to be a benign lesion and its relationship to invasive carcinoma remains unclear. Our data suggest that some apocrine hyperplasias may be clonal proliferations. The mean number of alterations are lower in apocrine hyperplasia, however the changes show considerable overlap with those identified in in situ and invasive apocrine carcinoma. These alterations are also commonly seen in nonapocrine breast cancer. The data are consistent with apocrine hyperplasia as a putative nonobligate precursor of apocrine carcinoma. (+info)Mixed apocrine/endocrine ductal carcinoma in situ of the breast coexistent with lobular carcinoma in situ. (8/80)
An unusual mixed form of ductal carcinoma in situ (DCIS) of the breast is described, which exhibits a biphenotypic morphology encompassing a range of differential diagnostic DCIS subtypes. In addition, immunophenotypic and ultrastructural studies demonstrate neuroendocrine and apocrine differentiation, raising questions regarding appropriate classification and biological behaviour. In two cases, coexistence of this mixed form of DCIS with lobular carcinoma in situ (LCIS) in the same duct lobular units is an additional unusual feature that might, at least in some cases, indicate a closer relation between them. (+info)Anal gland neoplasms are abnormal growths or tumors that develop in the anal glands, which are small glands located in the anus that produce lubricating fluid for bowel movements.
Anal gland neoplasms refer to abnormal growths or tumors that develop in the anal glands, which are small glands located in the anal canal. These neoplasms can be either benign or malignant, and they can occur in both men and women. Benign anal gland neoplasms are usually slow-growing and do not spread to other parts of the body. They can cause symptoms such as pain, itching, and bleeding during bowel movements. Malignant anal gland neoplasms, on the other hand, are more aggressive and can spread to other parts of the body, including the lymph nodes and other organs. The most common type of anal gland neoplasm is anal gland hyperplasia, which is a benign condition characterized by an overgrowth of the anal glands. Other types of anal gland neoplasms include anal gland adenoma, anal gland carcinoma, and anal gland sarcoma. Diagnosis of anal gland neoplasms typically involves a physical examination, imaging studies such as MRI or CT scans, and biopsy of the affected tissue. Treatment options depend on the type and stage of the neoplasm, and may include surgery, radiation therapy, chemotherapy, or a combination of these approaches.
Sweat gland neoplasms are abnormal growths that develop in sweat glands, which can be benign or malignant.
Sweat gland neoplasms are abnormal growths that develop in the sweat glands of the skin. They can be benign (non-cancerous) or malignant (cancerous). Some common types of sweat gland neoplasms include: 1. Syringoma: A benign tumor that develops in the eccrine sweat glands of the eyelids. 2. Sebaceous gland nevus: A benign tumor that develops in the sebaceous glands of the skin. 3. Malignant eccrine sweat gland carcinoma: A rare, but aggressive form of skin cancer that develops in the eccrine sweat glands. 4. Malignant apocrine sweat gland carcinoma: A rare, but aggressive form of skin cancer that develops in the apocrine sweat glands. Sweat gland neoplasms can be treated with a variety of methods, including surgery, radiation therapy, and chemotherapy. The best treatment option depends on the type and stage of the neoplasm, as well as the overall health of the patient.
Hidradenitis suppurativa is a chronic inflammatory skin disease that affects the sweat glands and surrounding tissue, causing painful, recurrent nodules, abscesses, and scarring.
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects the sweat glands (sebaceous glands) in the skin. It is also known as acne inversa or inverse psoriasis. HS typically presents as painful, inflamed nodules or lumps, often located in the axillae (armpits), groin, and under the breasts. These nodules can become infected and drain pus, leaving scars and causing significant discomfort and disfigurement. HS is a complex disease with a strong genetic component and is thought to be triggered by hormonal changes, immune system dysfunction, and other factors. Treatment options for HS include medications, surgery, and lifestyle changes.
Sweat gland diseases are medical conditions that affect the function or structure of sweat glands, leading to various symptoms such as excessive sweating, skin irritation, and infections.
Sweat gland diseases refer to a group of medical conditions that affect the sweat glands, which are responsible for producing sweat. These glands are found all over the body, and they play an important role in regulating body temperature and removing waste products from the skin. Sweat gland diseases can be classified into two main categories: primary and secondary. Primary sweat gland diseases are those that affect the sweat glands themselves, while secondary sweat gland diseases are those that result from an underlying medical condition or disorder. Some common examples of primary sweat gland diseases include: 1. Hyperhidrosis: This is a condition characterized by excessive sweating, which can be either focal (occurring in specific areas of the body) or generalized (occurring all over the body). 2. Anhidrosis: This is a rare condition in which the sweat glands do not produce any sweat. 3. Eccrine gland hypoplasia: This is a rare condition in which the sweat glands are underdeveloped or absent. 4. Apocrine gland hyperplasia: This is a condition in which the apocrine sweat glands (which are found in the armpits and groin area) become enlarged and produce an excessive amount of sweat. Secondary sweat gland diseases can result from a variety of underlying medical conditions, including: 1. Diabetes: People with diabetes may experience excessive sweating due to high blood sugar levels. 2. Thyroid disorders: Hyperthyroidism (an overactive thyroid gland) can cause excessive sweating, while hypothyroidism (an underactive thyroid gland) can cause decreased sweating. 3. Neurological disorders: Certain neurological disorders, such as Parkinson's disease and multiple sclerosis, can cause excessive sweating. 4. Infections: Infections such as tuberculosis and fungal infections can cause excessive sweating. 5. Medications: Certain medications, such as antidepressants and blood pressure medications, can cause excessive sweating as a side effect. Treatment for sweat gland diseases depends on the underlying cause and the severity of the condition. In some cases, lifestyle changes such as avoiding triggers that cause excessive sweating or wearing loose-fitting clothing may be sufficient. In more severe cases, medications or surgery may be necessary to manage symptoms.
Paget's Disease of the Extramammary Nipple is a rare, slow-growing cancer that affects the nipple and areola of the breast, typically in older men.
Paget's disease, also known as Paget's disease of bone, is a chronic bone disorder that affects the normal bone remodeling process. It is characterized by the excessive and abnormal growth of bone tissue, which leads to bone pain, deformity, and weakness. Extramammary Paget's disease refers to the occurrence of Paget's disease outside of the breast tissue. It most commonly affects the bones of the pelvis, spine, skull, and upper extremities. The exact cause of Paget's disease is not known, but it is thought to be related to genetic and environmental factors. The diagnosis of Paget's disease is typically made through a combination of physical examination, imaging studies such as X-rays, bone scans, and biopsy. Treatment options for Paget's disease depend on the severity and location of the disease, and may include medications to reduce bone turnover, surgery to remove affected bone, and radiation therapy.
Dog diseases refer to illnesses or medical conditions that affect dogs, including both infectious and non-infectious diseases.
In the medical field, "dog diseases" refers to any illness or condition that affects dogs. These diseases can be caused by a variety of factors, including genetics, infections, environmental factors, and lifestyle. Some common examples of dog diseases include: 1. Canine Influenza: A highly contagious respiratory disease caused by the influenza virus. 2. Canine Distemper: A highly contagious viral disease that affects the respiratory, gastrointestinal, and central nervous systems. 3. Canine Leukemia: A type of cancer that affects the white blood cells. 4. Canine Hip Dysplasia: A genetic disorder that affects the development of the hip joint. 5. Canine Heartworm: A parasitic disease that affects the heart and blood vessels. 6. Canine Cancers: A group of diseases that affect the body's cells and tissues. 7. Canine Arthritis: A joint disease that causes inflammation and pain. 8. Canine Allergies: A condition in which the immune system overreacts to certain substances, such as pollen or food. 9. Canine Eye Diseases: A group of conditions that affect the eyes, including cataracts, glaucoma, and retinal detachment. 10. Canine Skin Diseases: A group of conditions that affect the skin, including allergies, mange, and acne. These are just a few examples of the many diseases that can affect dogs. It is important for pet owners to be aware of the common diseases that affect their dogs and to take steps to prevent and treat them.

Secrete3
- When the sweat gland is stimulated, the cells secrete a fluid ( primary secretion ) that is similar to plasma -- that is, it is mostly water and it has high concentrations of sodium and chloride and a low concentration of potassium -- but without the proteins and fatty acids that are normally found in plasma. (howstuffworks.com)
- Apocrine glands , located mostly in the armpits, pubic area and scalp, secrete sweat that contains fats and other organic compounds. (healthydirections.com)
