Summary
Leukemia cutis (LC) can present as rare hyperpigmented skin patches, not just typical lesions. Early recognition of this unusual presentation in acute myeloid leukemia (AML) is crucial for timely diagnosis and improved patient outcomes.
Area of Science:
- Dermatology
- Hematology
- Oncology
Background:
- Leukemia cutis (LC) is a rare extramedullary manifestation of leukemia.
- Typically presents as papules, nodules, or plaques, commonly in acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL).
- Hyperpigmented macules and patches are an uncommon LC presentation.

Skin Cancer

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.

Pigmentation
4.1K
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...

Changes in Skin Color: Clinical Perspectives

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.
