Unrenewable Cells

In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...

Area of Science:

  • Dermatology
  • Medical Genetics

Background:

  • Mutilating keratoderma is a rare condition characterized by progressive hyperkeratosis and pseudoainhum.
  • Early onset and associated congenital anomalies, such as deafness, can occur.

Purpose of the Study:

  • To present a case of mutilating keratoderma with congenital deafness.
  • To emphasize the diagnostic role of histopathology in confirming the condition.

Main Methods:

  • Clinical presentation of a 30-year-old female patient with hyperkeratosis and digit constriction.
  • Histopathological examination of skin lesions.

Main Results:

  • The patient exhibited typical lesions of mutilating keratoderma, including hyperkeratosis of palms and soles since infancy.
  • Digit constriction was noted by age 5.
  • Histopathological findings supported the clinical diagnosis.

Conclusions:

  • Mutilating keratoderma can present with associated congenital conditions like deafness.
  • Histopathological examination is crucial for accurate diagnosis of this rare disorder.
