Dermatopathia Pigmentosa Reticularis Hyperkeratotica et Mutilans

Dermatopathia pigmentosa reticularis is a rare ectodermal dysplasia that presents with a triad of reticulate hyperpigmentation, nonscarring alopecia, and nail dystrophy. Dermatopathia pigmentosa reticularis (DPR), a rare form of autosomal dominant ectodermal dysplasia, was first described by Hauss and Oberste-Lehn in the year 1958.[rx] Defect in the N-terminal part of the keratin molecule results in loss of inhibition against proapoptotic signals. KRT14 mutation has resulted in a case of dermatographia pigmentosa reticularis with wiry scalp hair and digital fibromatosis.[rx] While reticulate hyperpigmentation involving the whole body, nail dystrophy, and nonscarring alopecia forms the classical triad of dermatopathia pigmentosa reticularis, other clinical features such as hypohidrosis or hyperhidrosis, palmoplantar thickening, and loss of dermatoglyphics and ainhum-like constrictions have also been reported.[rx]

Dermatopathia Pigmentosa Reticularis, often abbreviated as DPRH, is a rare genetic skin disorder. It affects the way your skin looks and behaves. People with DPRH might experience changes in skin color, texture, and even the way it grows.

Breaking Down the Name

Let’s take a closer look at the name to understand what each part means:

• Dermatopathia: This simply means a skin disorder.
• Pigmentosa: Refers to changes in skin color. Pigmentation gives our skin its unique hues.
• Reticularis: This term relates to a net-like pattern. Imagine a fishing net’s crisscross design – that’s the idea here.
• Hyperkeratotica: Hyper means “too much,” and keratotica refers to keratin, a protein in our skin. So, this points to an excess of keratin, which can lead to changes in skin texture.
• Mutilans: This term highlights the potential for skin changes to be severe or damaging.

Types

Breaking Down the Term

1. Dermatopathia:
   • What it means: Anything related to skin problems.
   • Simple explanation: Think of ‘derma’ as ‘skin’ and ‘pathia’ as ‘problems’. So, this part talks about skin-related issues.
2. Pigmentosa Reticularis:
   • What it means: A skin condition marked by a net-like (reticular) pattern of pigmentation.
   • Simple explanation: This is like a design or pattern on the skin that’s caused by changes in skin color. Picture a net, and imagine that pattern on the skin.
3. Hyperkeratotic:
   • What it means: Increased thickness of the outermost layer of the skin.
   • Simple explanation: It’s like when the top layer of your skin gets super thick. Think of it as a protective, but overly done, outer coat.
4. Et Mutilans:
   • What it means: Leading to tissue destruction or mutilation.
   • Simple explanation: This condition can cause parts of the body to get damaged or even disappear over time.

Causes

Now, let’s dive into its 30 causes:

1. Genetic Factors: Some people are born with genes making them more prone to this condition. Think of genes as tiny instruction manuals inside our bodies that determine how we look and function.
