Skin Cancer

5.7K
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...

Skin Diseases and Disorders

5.1K
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...

Assessment of the Mouth01:26

Assessment of the Mouth

1.0K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Area of Science:

  • Mycology
  • Infectious Diseases
  • Dermatology

Background:

  • Paracoccidioidomycosis is a systemic fungal infection endemic to Latin America.
  • It often presents with polymorphic mucocutaneous lesions, making early diagnosis challenging.

Purpose of the Study:

  • To report a case of paracoccidioidomycosis with atypical presentation.
  • To emphasize the importance of considering this infection in the differential diagnosis of mucocutaneous lesions.

Main Methods:

  • Clinical case presentation of a 50-year-old male.
  • Physical examination findings including facial plaques and oral lesions.
  • Histopathological examination revealing characteristic yeast morphology.

Main Results:

  • The patient presented with a five-month history of progressive facial lesions and oral stomatitis.
  • Histopathology confirmed Paracoccidioides spp. with a "mariner's wheel" budding yeast pattern.
  • Diagnosis of paracoccidioidomycosis was established based on clinical and histopathological findings.

Conclusions:

  • Paracoccidioidomycosis should be considered in patients with unexplained mucocutaneous lesions, especially in endemic areas.
  • The characteristic "mariner's wheel" pattern is a key diagnostic feature.
  • Prompt diagnosis and treatment are essential for managing this potentially severe fungal infection.
