Dermatology
Histopathology

Background:

Porokeratosis is a rare disorder of keratinization.
Linear porokeratosis follows Blaschko's lines, suggesting a mosaic genetic defect.

Observation:

A 66-year-old male presented with a 5-year history of linear lesions on his right lower extremity.
Lesions appeared as hyperpigmented and violaceous papules with hypopigmented centers and hyperkeratotic rims.
The distribution followed Blaschko's lines.

Findings:

Clinical presentation was characteristic of porokeratosis.
Histopathological examination confirmed the diagnosis of porokeratosis.
The specific subtype and its clinical course were documented.

Implications:

This case highlights the importance of recognizing porokeratosis variants.
Understanding the histopathological features is crucial for accurate diagnosis.
Reviewing associated conditions and treatments aids clinical management.
