Desmosomes01:05

Desmosomes

The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are  essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...
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...
Cellular Adaptation IV: Dysplasia and Metaplasia01:24

Cellular Adaptation IV: Dysplasia and Metaplasia

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
Diabetic Ketoacidosis l: Introduction01:25

Diabetic Ketoacidosis l: Introduction

DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic ketone production, and...
Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Summary

Dyskeratosis congenita is a rare genetic disorder. This case study highlights an unusual presentation with normal nails, a feature rarely seen in this syndrome.

Area of Science:

  • Genetics
  • Dermatology
  • Rare Diseases

Background:

  • Dyskeratosis congenita (DC) is a rare inherited bone marrow failure syndrome.
  • Characteristic features include mucocutaneous abnormalities and predisposition to cancer.
  • Typical mucocutaneous signs are skin atrophy/pigmentation, nail dystrophy, and oral leukoplakia.

Purpose of the Study:

  • To report an atypical case of Dyskeratosis congenita.
  • To highlight a rare variant of DC with normal nail findings.
  • To discuss the diagnostic challenges and implications of this presentation.

Main Methods:

  • Case report and clinical review.
  • Detailed patient history and physical examination.
  • Review of relevant literature on Dyskeratosis congenita variants.

Main Results:

  • The patient presented with skin atrophy, skin pigmentation, oral leukoplakia, and esophageal stricture.
  • Notably, the patient exhibited normal finger and toe nails.
  • This presentation deviates from the classic nail dystrophy associated with DC.

Conclusions:

  • Dyskeratosis congenita can present with significant variations.
  • Nail sparing is an extremely uncommon but possible manifestation of DC.
  • Recognition of atypical presentations is crucial for accurate diagnosis and management.
