Abstract:
We determined the prevalence of keratosis punctata of the palmar creases (KPPC) in 5000 individuals. The group screened included patients, visitors and children. Fifteen (0.3%) cases were discovered to have characteristic KPPC lesions. The patients were mainly young with a male predominance (14M : 1F). The lesions in almost all cases were asymptomatic. No predisposing factors could be ascertained by history. Histopathologically, the lesions consisted of focal hyperkeratosis, and an epidermal depression corresponding to the pits. Special stains did not reveal any dermal components in the keratin masses. On comparing our findings with those reported earlier it appears that KPPC is not so rare as believed.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

Cells of the Epidermis
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...
