White discharge inside the foreskin

Introduction The white secretion in the foreskin is mainly smegma, which is a chemical carcinogen secreted by the sebaceous glands of the male genital foreskin. There is a certain sebaceous gland distributed under the skin at the junction of the inner surface of the penis foreskin and the head of the penis. The gland continuously secretes some yellowish oily substances, which are mixed with the dirt and contaminated urine of the skin, and the time is longer. Thick, forming a sheet or small piece of material - smegma, and tightly adhered to the skin.

Cause

The foreskin is too long to be easily contaminated, and the sebum secreted by the foreskin cannot be discharged to form a strange white "skin scale" with the sediment in the urine. General smegma as long as you pay attention to daily cleaning will not be a serious problem, but some men's smegma suddenly increased, how is this going?

Some male friends have more smegma, but the reasons for the increase in smegma are not very clear. In fact, there are many reasons for this.

For example, infectious is often caused by unclean sexual intercourse, Staphylococcus, Streptococcus, Escherichia coli, Candida albicans, Trichomonas, Chlamydia, Mycoplasma, fungi, Gonococci or other bacteria; or because the foreskin is too long The cleaning is not enough. The unclean things between the foreskin and the glans, that is, the smegma, will accumulate and stimulate the inflammation of the local foreskin and mucous membranes.

1, check the test: Candida balanitis (the dermatitis) can be found in the lesions of the glans, foreskin microscopic examination or culture can be found Candida. Trichomonas balanitis can find trichomoniasis on secretions.

2, direct microscopic examination: scrape the surface scale of the glans glans, coronary sulcus or foreskin as the specimen to be examined. The specimens to be inspected were made with 10% potassium hydroxide or physiological saline, and clusters of egg-shaped spores and pseudohyphae were observed under the microscope. If more pseudohyphae were found, it indicated that Candida was in the pathogenic stage.

3, staining examination: Gram staining, Congo red staining or PAS staining after microscopic examination, the positive rate is higher than direct microscopy. Gram staining, spores and pseudohyphae dyed in blue: Congo red and PAS staining, spores and pseudohyphae dyed red.

4. Separation and culture: Candida culture can be performed on patients with negative smear test. The test specimens were inoculated on Sabouraud medium under aseptic conditions. When inoculation, the test tube culture medium was cut obliquely, and each tube was inoculated with 2-3 spots, and each sample was inoculated with 2 tubes. The medium was incubated in a 37 ° C incubator for 24-48 hours, and a large number of milky white colonies were observed. A small number of colony smears were picked with the inoculation needle, and microscopic examination or microscopic examination was performed. A large number of spores were observed. Diagnosed as a Candida infection.

5, Candida antibody test: Candida albicans antibody can be detected by immuno-double expansion method or latex coagulation method.

Differential diagnosis

1, penile syphilis

Most often occurs in the head of the penis and the foreskin, often with ulcers and exudates, but there is a history of unclean sexual intercourse. The small red spots that are initially congested develop into a typical ulcer within a week. The ulcer surface is superficial, the surface is flat, and the edges are high. The hair is hard, the serum is exuded at the bottom, and the dark vision test reveals the Treponema pallidum.

2, soft squat

The penis head and foreskin mucosa are moist, red, swollen, have secretions, and have a history of sexually transmitted diseases. The course of the disease is milder, the secretions are less, the odor is lighter, the inguinal lymph nodes are swollen, often forming edema, and the secretion is directly smeared. Or culture can be checked for D. faecalis.

3, gonorrhea

Has urethral redness, itching, pain, thin mucus or deep yellow pus, bilateral inguinal lymph nodes swelling, but there is a history of exposure, urethral pus smear staining can be found in multinucleated white blood cells have Gram-negative double Cocci are present.
