Why has my brown-black glans spot been growing for years?

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

I understand that noticing any patch on the glans can be quite concerning, especially when it has slowly increased in size and has now reached the meatus.

A brown black flat spot on the glans that has gradually enlarged over 1.5 to two years can be due to several causes.

The most common and benign cause is penile melanosis, also called genital lentiginosis, which presents as flat, brown-to-black patches that slowly enlarge over time but remain smooth and asymptomatic.

Other possibilities include a melanocytic nevus (a benign skin lesion formed by a cluster of melanocytes), a mole (a common, typically benign skin growth formed by clustered pigment-producing cells), or post-inflammatory hyperpigmentation (a common, harmless, and often temporary skin condition featuring flat, discolored, dark spots)if there was prior irritation, friction, or infection in that area.

However, any pigmented lesion on the glans that is progressively increasing in size, particularly one involving the meatus, must be examined carefully to rule out rarer but serious conditions such as penile melanoma (a highly aggressive form of cancer) or pigmented Bowen disease (a rare variant of squamous cell carcinoma).

Although penile melanoma is very rare, it can occur, and early detection is extremely important. Warning signs include irregular or poorly defined borders, variation in colour (e.g., different shades of brown, black, grey, or blue), asymmetry, ulceration, bleeding, itching, or a sudden, recent increase in size.

Since your lesion has been slowly growing and now involves the meatus, I strongly recommend an in-person evaluation by a dermatologist or urologist. A dermoscopic examination will help assess the pigmentation pattern, and if there are any suspicious features, a small biopsy may be advised to establish a definitive diagnosis. Most such lesions turn out to be benign, so please do not panic, but do not ignore them either.

Early assessment is always the safest approach. Please also share a clear photograph for more specific guidance.

I hope I have answered your question.

Let me know if I can assist you further.

Thank you.
