Pseudomelanosis

Pseudomelanosis, also known as pseudomelanosis or cadaveric melanosis, is a rare condition in which dark or black pigmentation forms on the surface of the skin or mucous membranes. However, unlike true melanosis, pseudomelanosis is not associated with the accumulation of melanin pigment.

Pseudomelanosis usually develops as a reaction of the body to certain stimuli or influences. This can be the result of various factors such as chemicals, medications, injury, infection, or even prolonged exposure to sunlight.

One of the most common causes of pseudomelanosis is tissue exposure to iron. When iron oxidizes due to injury or other exposures, it produces a black color that can lead to pseudomelanosis. This condition is often observed in patients receiving iron infusions or taking oral iron medications.

Symptoms of pseudomelanosis can vary depending on its cause and where it occurs. The pigmentation is usually black or dark brown and can be single or multiple. Often pseudomelanosis is not accompanied by other symptoms and does not cause discomfort or illness.

The diagnosis of pseudomelanosis is usually based on visual examination and the patient's medical history. In rare cases, a biopsy may be necessary to rule out other possible causes of pigmentation.

Treatment for pseudomelanosis is usually not required, as the condition usually does not cause problems or complications. However, if pigmentation causes significant discomfort or aesthetic concerns, various treatments such as laser therapy, chemical peels or cryotherapy can be used to improve the appearance of the skin.

In conclusion, pseudomelanosis is a rare condition in which black or dark pigmentation forms on the surface of the skin or mucous membranes. It usually does not require treatment and does not pose a health threat, but it can cause aesthetic problems. If you experience pigmentation on the skin or mucous membranes, it is recommended to consult a doctor for an accurate diagnosis and recommendations for skin care.

Pseudomelanosis is a focal spot of irregular shape, black in color, which is localized on the skin in those places where a malignant papilloma or angioma appears. The pathological process is actively developing in places subject to trauma and active irritating factors. Externally, such a neoplasm looks like a black or brown pigment spot, but no differences from normal skin are found on it. Swelling is also possible. Skin area with pseudochalk
