Skin Cancer

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...

Papillary Dermis

Papillary Dermis

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.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Area of Science:

Dermatology
Genetics

Background:

Familial benign pemphigus, also known as Hailey-Hailey disease, is a rare genetic blistering disorder.
Typically, it affects intertriginous areas like the neck, axillae, and groin.

Observation:

This report describes a unique case of Hailey-Hailey disease.
The patient presented with crusted, annular plaques exclusively on the back.
There was no involvement of typical intertriginous zones or a history of classical disease presentation.

Findings:

This case represents an atypical cutaneous manifestation of Hailey-Hailey disease.
The localization solely on the back without prior classical symptoms is unprecedented in medical literature.
This highlights the potential for varied clinical presentations in familial benign pemphigus.

Implications:

This atypical presentation broadens the differential diagnosis for back lesions.
It underscores the importance of considering genetic dermatoses even with unusual symptom distribution.
Further research may elucidate genetic or environmental factors influencing Hailey-Hailey disease phenotype.
