Late-onset disseminated superficial actinic porokeratosis in an elderly woman.

Abstract

INTRODUCTION:

Disseminated superficial actinic porokeratosis (DSAP) is the most common form of porokeratosis. A case of late-onset DSAP is reported with an uncommon presentation in an elderly patient.

METHODS:

An 80-year-old woman, with diabetes mellitus treated with metformin, and hypertension treated with metoprolol and captopril, presented with multiple 2 mm-to-7 cm brown patches, for 5 years. The patches were often confluent with an atrophic center and a well-demarcated keratotic border located on the thighs, lower legs, and feet.

RESULTS:

Histological examination of a cutaneous biopsy showed the presence of rare cornoid lamellae, confirming the clinical diagnosis of DSAP.

CONCLUSION:

In this report, the atypical presentation of DSAP is discussed in this elderly patient and also the possible triggering factors at this age.
