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...

Area of Science:

Dermatology
Surgical Pathology

Background:

Pilomatricoma is a rare, benign skin neoplasm originating from hair matrix cells.
These tumors are most commonly found in the head and neck region.

Observation:

A 55-year-old man presented with a progressively growing, painless, bleeding, fist-sized tumor on the left parietal region of his head.
The tumor had a partly livid and ulcerated surface with light-yellow chalky material and was pediculated, overlying the left parietal region and auricle.

Findings:

The mass was totally excised without observed infiltration of the skull.
Histopathological examination confirmed the diagnosis of a giant pilomatricoma.

Implications:

This case highlights the presentation and successful management of an unusually large pilomatricoma.
Understanding the characteristics of giant pilomatricoma is crucial for accurate diagnosis and surgical planning in head and neck oncology.
