Summary
This case report details an amelanotic lentigo maligna, a rare skin cancer variant, discovered incidentally. This specific case lacked typical visible or palpable features, highlighting diagnostic challenges.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Amelanotic lentigo maligna is a rare subtype of lentigo maligna.
- It often presents as subtle, erythematous, scaly macules.
- Misdiagnosis as benign dermatoses is common due to its non-specific appearance.
Observation:
- A case of amelanotic lentigo maligna was incidentally identified.
- The patient was an 87-year-old woman.
- This particular lesion exhibited no visible or palpable characteristics.
Findings:
- The amelanotic lentigo maligna was discovered via shave biopsy.
- The absence of typical clinical signs presented a diagnostic challenge.
- This case underscores the variability in presentation of this rare condition.
Implications:
- Highlights the importance of histological examination for diagnosing amelanotic lentigo maligna.
- Suggests that amelanotic lentigo maligna can present without any distinguishing clinical features.
- Emphasizes the need for increased awareness among clinicians regarding subtle presentations of lentigo maligna.

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
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.

Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
