Tuberculosis of the penis

Introduction to penile tuberculosis Penile tuberculosis is a special form of tuberculosis disseminated to the skin by blood. It is a variant of papular necrotic tuberculosis in skin tuberculosis. It mainly occurs in the glans or foreskin. The course of the disease is slow, after several months. After a few years, there may be small depressions and depressions, which are more common in young adults. basic knowledge The proportion of illness: 0.003% Susceptible people: male, more common in young adults. Infection method: pathogen infection Complications: tuberculosis, bone tuberculosis, kidney tuberculosis

Causes of penile tuberculosis

(1) Causes of the disease

The allergic reaction of the glans of the penis to the tuberculosis in other areas does not contain Mycobacterium tuberculosis in the lesion itself.

(two) pathogenesis

The patient has tuberculosis, bone tuberculosis, renal tuberculosis or other tuberculosis lesions, a late-onset allergic rash caused by tuberculosis spread to the penis by blood, and the penis is quickly eliminated.

Penile tuberculosis prevention

Precautionary principle: It is mainly to mobilize the masses, vigorously publicize the prevention and treatment knowledge of tuberculosis, conduct regular health checkups, early diagnosis, early treatment, eliminate infection sources, eliminate infection routes, carry out BCG vaccination, and enhance the body's resistance.

Penile tuberculosis complication Complications tuberculosis, tuberculosis, kidney tuberculosis

Often accompanied by other tuberculosis, such as tuberculosis (often low fever, night sweats, weight loss history), peritoneal tuberculosis, lymph node tuberculosis, bone tuberculosis, kidney tuberculosis.

Penile tuberculosis symptoms common symptoms red hay penis atrophy papule nodules

Initially a red or normal skin color of papules or small nodules from rice to peas, the toughness of the touch, the nodules can be naturally absorbed or the suppuration of the top, necrosis, ulceration, round or no plastic ulcer, the edge of the ulcer is slightly Pierced, the base is gray necrotic moss, there is a pus-like secretion, surrounded by invasive redness, starting with a single hair, after multiple hair, and can be fused together, consciously have tenderness, leaving a small scar after the scar, more common in Young adults, occur in the glans and the circumference of the coronary sulcus, chronic, can occur repeatedly, often accompanied by other tuberculosis.

Penile tuberculosis examination

Histopathological examination

There is limited local necrosis of the upper part of the dermis and the entire epidermis. There are non-specific inflammatory cell infiltration around the necrotic tissue, and there are tuberculous structures around it, thickening of the blood vessel wall or thrombosis.

Laboratory inspection

1. OT test: intradermal injection was performed on the inside of the patient's forearm with a skin test solution containing different concentrations of tuberculin. The first skin test solution concentration was 0.1 ml containing 1 unit of tuberculin. The local redness of the skin test was 48 hours after injection. The induration was positive in the case of 0.5 to 2 cm (+); redness and induration were 2 in diameter. Above centimeter, even blisters or necrosis are strongly positive (++).

2. Polymerase chain reaction (PCR) The secretion of the lesion is taken for the detection of Mycobacterium tuberculosis DN A. The method is highly specific and sensitive, but requires certain equipment. If it is contaminated during the test, it can produce false positives.

3. Tuberculosis pure protein derivative test (PPD) Penile tuberculosis rash can be positive.

Diagnosis and identification of penile tuberculosis

diagnosis

According to the red or normal skin color of the papules or small nodules from the beginning of the grain to the peas, the toughness, the nodules can be naturally absorbed or the suppuration, necrosis, ulceration, round or no plastic ulcer, the edge of the ulcer has Slightly worn, the base is gray necrotic moss, there is pus-like secretions, surrounded by infiltrative blush, starting with a single hair, after multiple hair, and can be fused together, consciously have tenderness, leaving a small scar after the depression, more Seen in the young and middle-aged, it occurs in the glans and the circumference of the coronary sulcus. Histopathology can be seen in the diagnosis of papular necrotic tuberculosis.

Differential diagnosis

1. The pathogen of soft chancre is Ducrey bacillus, which has significant damage to inflammation and severe pain. After acute, accompanied by acute lymphadenitis, there is a history of improper sexual intercourse.

2. The number of hard chancre is mostly isolated, the edge of the ulcer is neat, there is cartilage-like hardness, there is a dike-like infiltration around it, and the shallow and thin scars are formed later, and the syphilis spirochete can be found in the damage.

3. Condyloma acuminata: male patients occur in the foreskin ligament, coronary sulcus, foreskin, urethra, penis, around the anus and scrotum. At the beginning of the disease, it is a reddish or stained red-brown-sized scorpion, which is soft in nature and slightly pointed at the top, gradually growing or increasing. It can develop into a papillary or saclike shape, the base is slightly wide or banded, and the surface has particles.
