Hard lump at the base of the penis

If you find a hard lump at the base of the penis, do not apply any topical medication at home. You must go to the hospital for a specific andrological examination to find out whether you have a penile cyst or penile inflammation, because usually this situation will be accompanied by other symptoms, such as feeling redness, swelling and pain in your foreskin.

The glans penis and foreskin become red, swollen, painful, and itchy. Some may develop erosion and ulceration, and there may be yellow purulent secretions with a special odor. In severe cases, the glans penis may become necrotic. Some patients develop adhesion and stenosis of the urethra after the acute phase, causing difficulty in urination. Repeated infections can cause the glans penis or foreskin to thicken and form white spots. Long-term stimulation of the glans penis by smegma may also lead to penile cancer. The harm of penitis can be said to be "not shallow".

It is reported that about 85%-95% of penile cancer patients have a history of phimosis or prepuce. In addition, a wife's cervical cancer is also related to the irritation of her husband's smegma. Vulvitis is more common in men around 20-30 years old. The damage mainly occurs at the junction of the edge of the glans and the coronal sulcus and/or the frenulum. The damage is a papule of 1-3mm in size, and the damage on both sides of the frenulum is larger. The top of the papule is round and smooth, and some papules are hairy or filamentous. The papules are mostly not fused with each other, and are densely arranged in one or more rows. They are obvious on the dorsal side of the glans and can partially or completely surround the glans.

The color of the lesions is mostly pearly white, a few are light red and skin-colored, and some may have mild redness and swelling. There is no tenderness, no rupture, and the patient has no conscious symptoms. The histopathological examination of vulvitis shows hyperkeratosis, mild to moderate hyperplasia of the epidermis, normal basal layer, slight hyperplasia and density of collagen fibers in the dermis, and varying degrees of hyperplasia and dilation of dermal papillary capillaries, with a small amount of lymphocyte infiltration around, and no concave cells.

The key point of differential diagnosis of penile inflammation is that the lesions in the former are limited to the edge of the glans, the number of lesions is large, they are pearly white, the surface is smooth, the lesions do not increase with the extension of the disease course, and the acetic acid test is negative; while the lesions in the latter are not limited to the edge of the glans, they are mostly single and scattered, the lesions are large, the surface is not smooth, and they are mostly cauliflower-shaped. They gradually increase with the extension of the disease course, the acetic acid test is positive, and the tissue pathological examination shows concave cells.
