Summary
Two patients with similar skin pigmentation had different underlying causes: vitamin B12 deficiency and Addison's disease. Recognizing clinical signs aids in diagnosing and treating reversible causes of hyperpigmentation.
Area of Science:
- Dermatology
- Endocrinology
- Internal Medicine
Background:
- Skin hyperpigmentation can be a presenting sign for various systemic diseases.
- Differentiating causes of hyperpigmentation is crucial for appropriate management.
Observation:
- A case series of two patients presented with similar skin hyperpigmentation.
- One patient's hyperpigmentation was attributed to vitamin B12 deficiency.
- The other patient's hyperpigmentation was linked to Addison's disease.
Findings:
- Both vitamin B12 deficiency and Addison's disease can manifest with skin hyperpigmentation.
- Understanding the pathophysiology of hyperpigmentation in these conditions is key.
- Treatment response varied depending on the underlying diagnosis.
Implications:
- Highlights the importance of bedside clinical signs in diagnosing reversible causes of skin pigmentation.
- Emphasizes the need for a thorough differential diagnosis in patients with unexplained hyperpigmentation.
- Suggests that early identification of these conditions can lead to timely and effective treatment.

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.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

01:19Pigmentation
2.4K
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...
