Summary
Bladder melanosis, a rare condition, presents as black spots on the bladder wall. Diagnosis requires biopsy and regular cystoscopic follow-up, especially when malignancy is suspected.
Area of Science:
- Urology
- Pathology
Background:
- Melanosis of the bladder is an extremely rare condition, with limited documented cases.
- Neurogenic lower urinary tract dysfunction can be associated with various bladder pathologies.
Observation:
- An 80-year-old woman with spinal paralysis and neurogenic bladder dysfunction underwent diagnostic work-up.
- Cystoscopy revealed unexpected black spots within the bladder wall.
Findings:
- Histopathological examination confirmed the presence of benign suburothelial melanosis.
- The observed spots were not indicative of malignant melanoma.
Implications:
- Suspicion of malignancy during cystoscopy necessitates a biopsy for definitive diagnosis.
- Regular cystoscopic surveillance is recommended for patients diagnosed with bladder melanosis.

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

2.8K
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

01:19Pigmentation
5.0K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:14Changes in Skin Color: Clinical Perspectives
4.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

01:26The Micturition Reflex
3.6K
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...
