Pigmentation01:19

Pigmentation

4.7K
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

3.9K
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...

Ethnic Identity within a Larger Culture

349
Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

Signs of Puberty

1.7K
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Influence of Parents and Peers on Identity

609
Adolescence is a pivotal period of identity formation, during which individuals begin to answer questions central to their sense of self, such as "Who am I?" and "Who do I hope to become?" Both parents and peers play critical roles in guiding adolescents through this complex developmental phase.
Parental Influence on Identity Development
Parents serve as primary guides and managers in an adolescent's life, offering support instrumental in decision-making and personal growth....

Self-Evaluation: Self-Enhancement and Self-Verification

5.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Area of Science:

  • Dermatology
  • Clinical Case Study

Background:

  • Terra firma-forme dermatosis (TFFD) presents as acquired, unilateral, or bilateral, well-demarcated, hyperpigmented macules and patches.
  • It commonly affects the neck, trunk, and extremities, often mistaken for acanthosis nigricans or other pigmentary disorders.
  • The exact etiology remains unclear, but it is thought to be related to epidermal dysfunction and the accumulation of keratin and melanin.

Purpose of the Study:

  • To report a case of TFFD in a pediatric patient.
  • To describe the clinical presentation and diagnostic approach.
  • To highlight the efficacy of a simple treatment modality.

Main Methods:

  • A clinical diagnosis of TFFD was made in a 13-year-old female presenting with a year-long history of dark neck discoloration.
  • Treatment involved the application of 70% alcohol-soaked gauze to firmly wipe the affected skin.
  • Clinical improvement was assessed visually.

Main Results:

  • The patient presented with a unilateral, well-demarcated, hyperpigmented patch on the neck.
  • Following treatment with 70% alcohol wipes, complete resolution of the hyperpigmentation was observed.
  • The treatment was well-tolerated with no adverse effects reported.

Conclusions:

  • Terra firma-forme dermatosis is a benign condition that can be effectively treated with topical alcohol application.
  • This case underscores the importance of accurate clinical diagnosis and the utility of simple, non-invasive treatments for TFFD.
  • Early diagnosis and treatment can prevent misdiagnosis and unnecessary interventions for this common pediatric dermatosis.
