Skin Diseases and Disorders

3.7K
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...

Skin Cancer

4.0K
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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Facial discoid dermatosis (FDD) is a distinct facial skin condition.
  • It shares some clinical similarities with psoriasis, seborrheic dermatitis, and pityriasis rubra pilaris.

Purpose of the Study:

  • To characterize the clinical and histopathological features of FDD.
  • To investigate treatment outcomes in a cohort of FDD patients.

Main Methods:

  • Retrospective multicenter study.
  • Involved 13 patients diagnosed with FDD between 2014-2022 in Spain.
  • Collected data on demographics, clinical presentation, histopathology, and treatment.

Main Results:

  • FDD presents as erythematous-orange, nummular papules/plaques with dry scales on the face.
  • Histopathology consistently showed psoriasiform hyperplasia with confluent parakeratosis.
  • No neutrophils were observed within epidermal layers.

Conclusions:

  • FDD exhibits unique clinical and histological characteristics.
  • The findings support FDD as a distinct dermatosis.
  • Further research is needed to understand FDD pathogenesis and develop targeted therapies due to treatment variability.
