A 2006 review stated that RS often leads renal cancer between ages 30-50. Renal cancer kills about 1 in 3 people, but 5-year survival rates improved between 1974-1976 and 1995-2000, from 52% to 64%.

Uterine fibroids can be treated with the same methods like sporadic uterine fibroids including antihormonal treatment, surgery or embolisation. Substantially elevated risk of progression to or independent development of uterine leiomyosarcoma has been reported which may influence treatment methods.

The predisposition to renal cell cancer calls for screening and, if necessary, urological management.

The skin lesions may be difficult to treat as they tend to recur after excision or destructive treatment. Drugs which affect smooth muscle contraction, such as doxazosin, nitroglycerine, nifedipine and phenoxybenzamine, may provide pain relief.

Topical lidocaine patches have been reported to decrease in severity and frequency of pain cutaneous leiomyomas.

MEM comprises a heterogeneous group of neoplasms believed to originate from the neural crest. First hints to this type of tumor were probably from Shuangshoti and Nestky (1971) and from Holimon and Rosenblum (1971) (2-3). Additional contributions were provided thereafter by Naka et al. (1975), Karcioglu et al. (1977), Cozzutto et al. (1982) and Kawamoto et al. (1987).

Kosem et al. collected 44 cases of MEM in a 2004 review and examined management data finding out that resection with pre- or post-surgery chemotherapy yielded the best results with one death only in 13. In the five cases reported by Mouton et al. an aggressive chemotherapy and adequate surgical excision granted a disease-free interval for 7 to 50 months. The attainability of radical surgical

ablation seems the most important prognostic factor (10).

Malignant ectomesenchymoma is a rare, fast-growing tumor of the nervous system or soft tissue that occurs in children and young adults. Malignant ectomesenchymomas may form in the head and neck, abdomen, perineum, scrotum, or limbs. Also called ectomesenchymoma.

Ectomesenchymoma is a rare, fast-growing tumor of the nervous system or soft tissue that occurs mainly in children, although cases have been reported in patients up to age 60. Ectomesenchymomas may form in the head and neck, abdomen, perineum, scrotum, or limbs. Also called malignant ectomesenchymoma.

Malignant ectomesenchymoma (MEM) is a rare tumor of soft tissues or the CNS, which is composed of both neuroectodermal elements [represented by ganglion cells and/or well-differentiated or poorly differentiated neuroblastic cells such as ganglioneuroma, ganglioneuroblastoma, neuroblastoma, peripheral primitive neuroectodermal tumors – PNET] and one or more mesenchymal neoplastic elements, usually rhabdomyosarcoma . The most accepted theory suggests that this tumor arises from remnants of migratory neural crest cells and thus from the ectomesenchyme.

The following methods are employed in the treatment of basal-cell carcinoma (BCC):

The three basic types of treatment are surgery, radiation therapy, and chemotherapy.

Surgery is performed by urologists; radiation therapy is administered by radiation oncologists; and chemotherapy is the work of medical oncologists. In most patients with testicular cancer, the disease is cured readily with minimal long-term morbidity. While treatment success depends on the stage, the average survival rate after five years is around 95%, and stage 1 cancers cases, if monitored properly, have essentially a 100% survival rate.

Basal-cell carcinoma is a common skin cancer and occurs mainly in fair-skinned patients with a family history of this cancer. Sunlight is a factor in about two-thirds of these cancers; therefore, doctors recommend sunscreens with at least SPF 30. One-third occur in non-sun-exposed areas; thus, the pathogenesis is more complex than UV exposure as "the" cause.

The use of a chemotherapeutic agent such as 5-Fluorouracil or imiquimod, can prevent development of skin cancer. It is usually recommended to individuals with extensive sun damage, history of multiple skin cancers, or rudimentary forms of cancer (i.e., solar keratosis). It is often repeated every 2 to 3 years to further decrease the risk of skin cancer.

The initial treatment for testicular cancer is surgery to remove the affected testicle (orchiectomy). While it may be possible, in some cases, to remove testicular cancer tumors from a testis while leaving the testis functional, this is almost never done, as the affected testicle usually contains pre-cancerous cells spread throughout the entire testicle. Thus removing the tumor alone without additional treatment greatly increases the risk that another cancer will form in that testicle.

Since only one testis is typically required to maintain fertility, hormone production, and other male functions, the afflicted testis is almost always removed completely in a procedure called inguinal orchiectomy. (The testicle is almost never removed through the scrotum; an incision is made beneath the belt line in the inguinal area.) In the UK, the procedure is known as a radical orchidectomy.

Chimney sweeps' carcinoma is a squamous cell carcinoma of the skin of the scrotum. Warts caused by the irritation from soot particles, if not excised, developed into a scrotal cancer. This then invaded the dartos, enlarged the testicle, and proceeded up the spermatic cord into the abdomen where it proved fatal.

Extramammary Paget's disease is usually seen in isolation and is associated with an underlying invasive malignancy about 12% of the time. It is associated with an underlying adnexal malignancy about 24% of the time. Paget's disease of the breast is almost always associated with an underlying invasive malignancy, i.e. breast cancer (e.g. mammary ductal carcinoma).

Verruciform xanthoma is uncommon, with a female:male ratio of 1:1.1

Extramammary Paget’s disease (EMPD), also extramammary Paget disease, is a rare, slow-growing, usually noninvasive intraepithelial (in the skin) adenocarcinoma outside the mammary gland and includes Paget's disease of the vulva and the extremely rare Paget's disease of the penis.

Verruciform xanthoma is an uncommon benign lesion that has a verruciform (wart-like) appearance, but it may appear polypoid, papillomatous, or sessile. The verruciform was first described by Shafer in 1971 on the oral mucosa. Usually found on the oral mucosa of middle-aged persons, verruciform xanthomas have also been reported on the scrotum and penis of middle-aged to elderly Japanese males. While the most common site is the oral mucosa, lesions that occur elsewhere usually arise on the perineum or on the skin with some predisposing factor, such as lymphedema or an epidermal nevus.

Treatment may involve surgery, which is currently the only recommended intervention. Surgery should include the removal of even small nodules, to prevent the recurrence of the scrotal calcinosis.

Chimney sweeps' carcinoma was first described by Percivall Pott in 1775 who postulated that the cancer was associated with occupational exposure to soot. The cancer primarily affected chimney sweeps who had been in contact with soot since their early childhood. The median age of onset of symptoms in one review was 37.7 years, although boys as young as 8 years old were found to have the disease. It was proposed by W.G. Spencer in 1890 that sweat running down their bodies had caused soot to accumulate in the rugae of the inferior surfaces of the scrotum, with the resulting chronic irritation causing scrotal cancer, but this was shown to be an incorrect artifact of the method used to stain his microscope slides.

In 1922, R.D. Passey, a research physician at Guy's Hospital in London produced malignant skin tumors in mice exposed to an extract made from soot, demonstrating the presence of carcinogenic substances in soot which were the likely cause of cancer of the scrotum in chimney sweeps.

in the 1930s Ernest Kennaway and James D. Cook of the Research Institute of the Cancer Hospital, London, (later known as the Royal Marsden Hospital) discovered several polycyclic hydrocarbons present in soot that were potent carcinogens: 1,2,5,6-dibenzanthracene; 1,2,7,8-dibenzanthracene; and 1,2-benzpyrene (3) benzo[α]pyrene. DNA consists of sequences of four bases – adenine, thymine, cytosine and guanine – bound to a deoxyribonucleic backbone. Benzo[α]pyrene interacts with deoxyguanosine of the DNA, damaging it and potentially starting the processes that can lead to cancer.

Most doctors consider this a normal physiological phenomenon and advise against treatment.

Idiopathic scrotal calcinosis (also known as idiopathic calcified nodules of the scrotum) is a cutaneous condition characterized by calcification of the skin resulting from the deposition of calcium and phosphorus occurring on the scrotum. However, the levels of calcium and phosphate in the blood are normal. Idiopathic scrotal calcinosis typically affects young males, with an onset between adolescence and early adulthood. The scrotal calcinosis appears, without any symptoms, as yellowish nodules that range in size from 1 mm to several centimeters.

Because polyorchidism is very uncommon, there is no standard treatment for the condition. Prior to advances in ultrasound technology, it was common practice to remove the supernumerary testicle. Several cases have been described where routine follow-up examinations conducted over a period of years showed that the supernumerary testicle was stable.

A meta-analysis in 2009 suggested removing non-scrotal supernumerary testicles because of the increased risk of cancer, and regular follow-up in the remaining cases to ensure that the supernumerary testicle remains stable.

A ectopic testis is a testicle that, although not an undescended testicle, has taken a non-standard path through the body and ended up in an unusual location.

The positions of the ectopic testis may be: in the lower part of the abdomen, front of thigh, femoral canal, skin of penis or behind the scrotum. The testis is usually developed, and accompanied by an indirect inguinal hernia. It may be divorced from the epididymis which may lie in the scrotum.

Shawl scrotum is a condition in which the scrotum surrounds the penis, resembling a 'shawl'.

It is a characteristic of some syndromes such as Aarskog-Scott syndrome (faciodigitogenital syndrome), Rubenstein-Taybi syndrome, craniofrontonasal dysplasia, Hunter Carpenter McDonald Syndrome, Naguib Syndrome, Saito Kuba Tsuruta Syndrome, Ieshima Koeda Inagaki syndrome, Cystic fibrosis Gastritis Megaloblastic Anemia, Willems de Vries syndrome, Schinzel syndrome and Seaver Cassidy syndrome.

Small cysts are best left alone, as are larger cysts that are an asymptomatic condition. Only when the cysts are causing discomfort and are enlarging in size, or the patient wants the spermatocele removed, should a spermatocelectomy be considered. Pain may persist even after removal.

Spermatocelectomy can be performed on an outpatient basis, with the use of local or general anesthesia.

A spermatocelectomy will not improve fertility.

This variation of normal anatomy is seen in the majority of adults. It is estimated about 80% of people have oral Fordyce spots, but seldom are granules found in large numbers. They are not usually visible in children, and tend to appear at about age 3, then increasing during puberty and become more obvious in later adulthood. They are more prominent in males.

If splenectomy is performed for conditions in which blood cells are sequestered in the spleen, failure to remove accessory spleens may result in the failure of the condition to resolve. During medical imaging, accessory spleens may be confused for enlarged lymph nodes or neoplastic growth in the tail of the pancreas, gastrointestinal tract, adrenal glands or gonads.

It is also known that disruption of the endocrine system by certain chemicals adversely affects the development of the reproductive system and can cause vaginal cancer. Many other reproductive diseases have also been link to exposure to synthetic and environmental chemicals. Common chemicals with known links to reproductive disorders include: lead, dioxins and dioxin-like compounds, styrene, toluene, BPA (Bisphenol A) and pesticides.
