Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Skin Cancer01:30

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Cirrhosis I: Introduction01:23

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...

Area of Science:

  • Genetics
  • Dermatology
  • Endocrinology

Background:

  • Carney complex (CNC) is an autosomal dominant syndrome characterized by myxomas, spotty skin pigmentation, and endocrine overactivity.
  • Cutaneous manifestations are key for early CNC diagnosis, potentially preventing severe complications like cardiac myxomas and endocrine abnormalities.
  • Distinguishing CNC-related pigmented lesions from other skin conditions is crucial for accurate risk assessment, as CNC patients lack skin cancer predisposition.

Purpose of the Study:

  • To review current knowledge on cutaneous pathology in Carney complex.
  • To present recent findings on the molecular basis of CNC.
  • To highlight the diagnostic importance of pigmented skin lesions in CNC.

Main Methods:

  • Literature review of existing studies on Carney complex.
  • Analysis of diagnostic criteria and clinical manifestations.
  • Summary of recent research on the molecular genetics of CNC.

Main Results:

  • Pigmented skin lesions are present in over half of CNC patients and are vital for early diagnosis.
  • CNC patients do not exhibit a predisposition to skin cancers, unlike some other genetic syndromes with cutaneous lesions.
  • Understanding the molecular basis is advancing the study of CNC pathogenesis.

Conclusions:

  • Cutaneous manifestations are critical for early Carney complex detection and management.
  • Accurate differentiation of CNC-related skin lesions is essential for patient risk stratification.
  • Further research into the molecular underpinnings of CNC is ongoing.
