Summary
This study describes a rare case of speckled lentiginous nevus with extensive unilateral distribution in a 53-year-old man. Pathologists should note this variant due to potential malignant transformation risks.
Area of Science:
- Dermatology
- Pathology
Background:
- Speckled lentiginous nevus is a rare melanocytic nevus.
- Unusual presentations and extensive distributions are infrequently documented.
Observation:
- A 53-year-old male presented with a speckled lentiginous nevus exhibiting extensive unilateral distribution.
- Lesions covered the left back, thorax, arm, and forearm, with a background pigmentary patch on the back and upper arm.
Findings:
- Histologic examination revealed a combined lentiginous and congenital nevocytic pattern.
- This pattern was present even in non-tanned skin areas, aligning with both typical and unusual speckled lentiginous nevus descriptions.
Implications:
- This case highlights infrequent variants of speckled lentiginous nevus with extensive unilateral distribution.
- Pathologists must be vigilant for such presentations due to the potential for malignant transformation.
