Is melanosis a conjunctival cancer?

Conjunctival PAM is often precancerous and leads to life-threatening malignant melanoma. Conjunctival PAM should be treated with surgery, cryotherapy, or sometimes chemotherapy eye-drops to eradicate it before melanoma develops.

Is conjunctival melanoma rare?

It arises from melanocytes located amongst the basal cells of the conjunctival epithelium. It is an uncommon tumor which comprises about 2% of all eye tumors, 5% of melanomas in the ocular region [1] and 0.25% of all melanomas overall [2].

Can conjunctival melanoma be cured?

A conjunctival melanoma is usually treated with surgery, although the use of cold to destroy affected tissue (cryotherapy) has also been used.

How do you get vulvar melanoma?

Risk factors

Increasing age. The risk of vulvar cancer increases with age, though it can occur at any age.
Being exposed to human papillomavirus (HPV).
Smoking.
Having a weakened immune system.
Having a history of precancerous conditions of the vulva.
Having a skin condition involving the vulva.

Does melanosis go away?

There is no treatment for melanosis coli. According to research published in the British Medical Journal, it’s generally reversible within 6 to 12 months after a person stops using anthraquinone-containing laxatives.

Can melanosis turn into melanoma?

They confirmed that genital melanosis can clinically mimic melanoma but the typical age of onset is younger than for genital melanoma, which is usually in the fifth to sixth decade. A majority of lesions were found to stabilize or regress over time.

Is vulvar melanoma curable?

In the United States, women with vulvar melanoma had a median survival of 61 months, with a 60% adjusted (for expected mortality) survival rate at 5 years and a 50% rate at 10 years. Survival for US women with vaginal melanoma was markedly worse than for those with vulvar melanoma.

What is the diagnosis of conjunctival melanoma in adults?

The diagnosis of conjunctival melanoma is suspected particularly in an adult patient who notes the onset of a new pigmented lesion on the surface of the eye. There are several pigmented conjunctival tumors, including nevus, racial melanosis, primary acquired melanosis, and melanoma.

Are there different types of pigmented Conjunctival Tumors?

There are several pigmented conjunctival tumors, including nevus, racial melanosis, primary acquired melanosis, and melanoma. In most instances, a clinical examination can differentiate these conditions. Nevi are generally present since childhood and often display subtle intrinsic cysts.

Are there any effective therapies for conjunctival melanoma?

Given that conjunctival melanoma is genetically similar to cutaneous melanoma, targeted therapies such as BRAF inhibitors and KIT inhibitors may be effective in the treatment of patients with metastatic conjunctival melanoma. Nevi are usually stationary but can exhibit growth due to hormonal changes or local inflammation.

How is chemotherapy used to treat conjunctival pigmented lesions?

Double-freeze, slow-thaw cryotherapy, the technique used at the margins of excisions, may also be used for cases in which the pigmentation cannot be excised, such as diffuse pigment on the tarsal conjunctiva. Topical chemotherapy is not used as a primary therapy for pigmented lesions.
