Syphilis is a sexually transmitted disease caused by the spirochete bacteria Treponema pallidum. Syphilis is treatable with antibiotics, but can have serious complications if not treated soon after infection. Both men and women can have syphilis, and it can be passed on from an infected pregnant woman to her unborn infant. 

  Syphilis occurs in 3 stages. In stages 1 and 2 a person is infectious during sexual contact. The condition is transmitted by skin-to-skin contact with an infected area. Sores develop on the site that has touched the infectious area. Depending on the type of sexual contact, sores may therefore appear on or near the genitals, lips, fingers or anus. The hard, usually painless sores can appear any time between 10 days to 3 months after acquiring the infection. Two to four months after infection there may be symptoms including a skin rash, patchy hair loss, fever, lumps around the genitals and anus, or general tiredness. If not treated, these symptoms may disappear and then recur over the next two years. The rash can be all over the body and is very contagious. An infected, but untreated, person may remain infectious through sexual contact for 2 years. 


Many cases of hair loss are temporary (for example, due to chemotherapy) or a natural part of ageing and don't need treatment. However, hair loss can have an emotional impact, so it is best to seek treatment if you are uncomfortable with your appearance.

If hair loss is caused by an infection or another dermatological condition, such as lichen planus or discoid lupus, treating the underlying problem may help to prevent further hair loss.

Male-pattern baldness is can also be treated with topical or systemic treatment.

Sexually transmitted diseases (STDs), or sexually transmitted infections (STIs), are generally acquired by sexual contact. The organisms that cause sexually transmitted diseases may pass from person to person in blood, semen, or vaginal and other bodily fluids.

Some such infections can also be transmitted nonsexually, such as from mother to infant during pregnancy or childbirth, or through blood transfusions or shared needles.

It's possible to contract sexually transmitted diseases from people who seem perfectly healthy — people who, in fact, aren't even aware of being infected. Many STDs cause no symptoms in some people, which is one of the reasons experts prefer the term "sexually transmitted infections" to "sexually transmitted diseases."

Sexually transmitted infections (STIs) have a range of signs and symptoms. That's why they may go unnoticed until complications occur or a partner is diagnosed. 

Signs and symptoms that might indicate an STI include:

  • Sores or bumps on the genitals or in the oral or rectal area
  • Painful or burning urination
  • Discharge from the penis
  • Vaginal discharge
  • Unusual vaginal bleeding
  • Sore, swollen lymph nodes, particularly in the groin but sometimes more widespread
  • Lower abdominal pain
  • Rash over the trunk, hands or feet

Signs and symptoms may appear a few days to years after exposure, depending on the organism. They may resolve in a few weeks, even without treatment, but progression with later complications — or recurrence — sometimes occurs.


The skin check by the dermatologist is the most effective method for the skin cancer prevention. The frequency of the dermatlogical skin check is variable and mainly depends on patient  personal and family history of melanoma and patient skin type (subjects with very light skin have higher risk of skin cancer). 
The frequency of the dermatological control should also depend on the amount and the type of  sun exposure that the patient has had during his/her childhood.  Sun burns is the most important risk factor for cutaneous cancer. Based on patient personal characteristics, the dermatologist will recommend a specific frequency for follow-up visits. On average, a dermatologic skin check is recommended every 12 months

Melanoma and Non Melanoma Skin Cancer

Melanoma is the most serious type of skin cancer. It begins in skin cells called melanocytes. Though melanoma is predominantly found on the skin, it can even occur in the eye.

The first sign of melanoma is often a change in the size, shape, or color of a mole. But melanoma can also appear on the body as a new mole. The chance of getting melanoma increases as you get older, but people of any age can get melanoma. In fact, melanoma is one of the most common cancers in young adults. Melanoma is a serious and sometimes life-threatening cancer. If melanoma is found and treated in its early stages, the chances of recovery are very good. If it is not found early, melanoma can grow deeper into the skin and spread to other parts of the body.


The most common non-melanoma skin cancers are basal cell carcinoma and squamous cell carcinoma. They two type of cancer are very common in Caucasian population. They usually start in the basal cells or squamous cells, which is how they get their names. Most non-melanoma skin cancers develop on sun-exposed areas of the body, like the face, ear, neck, lips, and the backs of the hands. Depending on the type, they can be fast or slow growing, but they rarely spread to other parts of the body.
