Sertoli Cell

December 16, 2008

International patients are coming for surgeons of gynecmastia surgery at hospitals of India in major industrialized cities like Mumbai. Some neoplasms that overproduce estrogens also possess aromatase overactivity. Sertoli Cell tumors in boys with Peutz-Jegher syndrome, an autosomal dominant disease characterized by pigmented macules on the lips, gastrointestinal polyposis and hormonally active tumors in males and females, for instance, have repeatedly demonstrated aromatase overactivity, resulting in gynecomastia, rapid growth and advanced bone age as presenting features. Feminizing Sertoli cell tumors with increased aromatase activity can also be seen in the Carney complex, an autosomal dominant disease characterized by cardiac myxomas, cutaneous pigmentation, adrenal nodules and hypercortisolism. Other than sex-cord tumors, fibrolamellar hepatocellular carcinoma has also been shown to possess ectopic aromatase activity, causing severe gynecomastia in a 17-year-old boy. Furthermore, adrenal tumors can secrete excess dehydroepiandrosterone (DHEA), DHEA-sulfate (DHEAS) and androstenedione that can then be aromatized peripherally to estradiol.

Germ cell tumors

December 8, 2008

Click this link for surgeons of gynecomastia surgery at hospitals of Hyderabad in India. Germ cell tumors are the most common cancer in males between the ages of 15 and 35. They are divided into seminomatous and nonseminomatous subtypes and include embryonal carcinoma, yolk sac carcinoma, choriocarcinoma and teratomas. Elevated a fetoprotein (AFP) and b HCG function as reliable markers in some tumors. As a result of the increased b HCG, acting analogously to LH to stimulate the Leydig cell LH receptor, testicular estrogen production is also increased, which, in turn, can cause gynecomastia. Although germ cell tumors generally arise in the testes, they can also originate extra-gonadally, specifically in the mediastinum. These extragonadal tumors also possess the capability of producing b HCG, but they must be differentiated from a multitude of other tumors such as large cell carcinomas of the lung which can synthesize ectopic b HCG. Surgeons of gynecomastia surgery at hospitals of Hyderabad in India are possible because some medical tourism companies are arranging it at a low cost.


Sertoli cell tumors

December 3, 2008

With a warm friendly ambience India can be an affordable, enjoyable, confidential, and safe alternative for surgeons of gynecomastia surgery at hospitals of Pune as compared to USA, UK. Sertoli cell tumors comprise less than 1% of all testicular tumors and occur at all ages, but one third have occurred in patients less than 13 years, usually in boys under 6 months of age. Although they arise in young boys, they usually do not produce endocrinologic effects in children. Again, the majority is benign, but up to 10% is malignant. Gynecomastia occurs in one third of cases, presumably due to increased estrogen production. Granulosa cell tumors, which occur very rarely in the testes, can also overproduce estrogen. In fact, only eleven cases have been reported with gynecomastia as a presenting feature in half of them. Visit here for surgeons of gynecomastia surgery at hospitals of Pune in India.


Interstitial cell tumors

November 25, 2008

Click here for surgeons of gynecomastia surgery at hospitals of Chennai in India. Interstitial cell tumors, or Leydig cell tumors constitute 1%-3% of all testis tumors. Usually, they occur in men between the ages of 20 and 60, although up to 25% of them occur prepubertally. In prepubertal cases, isosexual precocity, rapid somatic growth, and increased bone age with elevated serum testosterone and urinary 17-ketosteroid levels are the presenting features. In adults, elevated estrogen levels coupled with a palpable testicular mass and gynecomastia may develop. Though mostly benign, Leydig cell tumors may be malignant and metastasize to lung, liver, and retroperitoneal lymph nodes.

Tumors

November 17, 2008

Patients will benefit from well-trained, multi-language personnel, convenient transportation during surgery by surgeons of gynecomastia at hospitals of Delhi in India. The hospital provides clean and high-class accommodations, state-of-the-art medical equipment and excellent service. Testicular tumors can lead to increased blood estrogen levels by: estrogen overproduction; androgen overproduction with aromatization in the periphery to estrogens; and by ectopic secretion of gonadotropins which stimulate otherwise normal Leydig cells. Tumors causing an overproduction of estrogen represent an unusual but important cause of estrogen excess. Examples of estrogen-secreting tumors include: Leydig cell tumors, Sertoli cell tumors, granulosa cell tumors and adrenal tumors.

Pathologic gynecomastia

November 10, 2008

Increased estrogen

 

Click here for surgeons of gynecomastia surgery at hospitals of Mumbai in India. Since the development of breast tissue in males occurs in an analogous manner to that in females, the same hormones that affect female breast tissue can cause gynecomastia. The testes secrete only 6-10 mg of estradiol and 2.5 mg of estrone per day. Since this only comprises a small fraction of estrogens in circulation (i.e. 15% of estradiol and 5% of estrone), the remainder of estrogen in males is derived from the extraglandular aromatization of testosterone and androstenedione to estradiol and estrone, respectively. Thus, any cause of estrogen excess from overproduction to peripheral aromatization of androgens can initiate the cascade to breast development. Surgeons of gynecomastia surgery at hospitals of Mumbai in India excel in providing confidential arrangements for private medical and surgical vacations that are no one’s business but your own.

 


Estrogen levels

November 5, 2008

International patients are coming for surgeons of gynecomastia surgery at hospitals of Bangalore in India in major industrialized cities. For instance, investigators have shown increased urinary estrogen levels in obese individuals, and have demonstrated aromatase expression in adipose tissue. Thus, like the gynecomastia of obesity, the gynecomastia of aging may partly result from increased aromatase activity, causing increased circulating estrogen levels. Moreover, not only does total body fat increase with age, but there may be an increase in aromatase activity in the adipose tissue already present, increasing circulating estrogens even further. Lastly, SHBG increases with age in men. Since SHBG binds estrogen with less affinity than testosterone, the bioavailable estradiol to bioavailable testosterone ratio may increase in the obese older male.

Pubertal gynecomastia

October 31, 2008

Take a look for surgeons of gynecomastia surgery at hospitals of Hyderabad in India. Estrogens, however, rise throughout the entire day. Some studies have shown that a decreased androgen to estrogen ratio exists in boys with pubertal gynecomastia when compared with boys who do not develop gynecomastia. Furthermore, another study showed increased aromatase activity in the skin fibroblasts of boys with gynecomastia. Thus, the mechanism by which pubertal gynecomastia occurs may be due to either decreased production of androgens or increased aromatization of circulating androgens, thus increasing the estrogen to androgen ratio. The third age range in which gynecomastia is frequently seen is during older age (>60 years). Although the exact mechanisms by which this can occur have not been fully elucidated, evidence suggests that it may result from increased peripheral aromatase activity secondary to the increase in total body fat, coupled with mild hypogonadism associated with aging.

Physiologic gynecomastia

October 20, 2008

Medical tourism is going to deal with surgeons of gynecomastia surgery at hospitals of Chennai in India run by corporate entities.  Gynecomastia, breast development in males, can occur normally during three phases of life. The first occurs shortly after birth in both males and females. This is caused by the high levels of estradiol and progesterone produced by the mother during pregnancy, which stimulates newborn breast tissue. It can persist for several weeks after birth and can cause mild breast discharge called “witch’s milk”. Puberty marks the second situation in which gynecomastia can occur physiologically. In fact, up to 60% of boys have detectable gynecomastia by age 14. Although it is mostly bilateral, it can occur unilaterally, and usually resolves within 3 years of onset. Interestingly, in early puberty, the pituitary gland releases gonadotropins in order to stimulate testicular production of testosterone mostly at nighttime.

Male transgenics

October 14, 2008

Visit here for surgeons of gynecomastia surgery at hospitals of Goa in India. In female transgenetics, over expression of aromatase promotes the induction of hyperplastic and dysplastic changes in breast tissue. Over expression of aromatase in male transgenics caused increased mammary growth and histological changes similar to gynecomastia, an increase in estrogen and progesterone receptors and an increase in downstream growth factors such as TGF-beta and bFGF. Interestingly, treatment with an aromatase inhibitor leads to involution of the mammalian gland phenotype. Thus, although androgens do not stimulate breast development directly, they may do so if they aromatize to estrogen. This occurs in cases of androgen excess or in patients with increased aromatase activity. If anything, increased demand on surgeons of gynecomastia surgery at hospitals of Goa in India due to medical tourism may result in their expansion.
