Fluid-Filled Striae: Benign Phenomenon with a Dramatic Presentation

Introduction
Striae distensae are common linear scars that occur as a result of dermal damage. They are typically associated with rapid weight gain, pregnancy, or systemic corticosteroid use. A remarkably rare phenomenon with interstitial fluid collecting within pre-existing striae distensae may occur in conditions characterized by severe edema.

Objective
Here we present 2 cases of patients with fluid-filled striae distensae due to hypoalbuminemia of different origin.

Case report
Physical examination of a 30-year-old male patient with a history of septic shock revealed fluid-filled skin lesions within pre-existing striae distensae on both thighs. In the other patient, linear tense bullae located unilaterally on the skin of the abdomen were found. Laboratory tests revealed hypoalbuminemia in both patients.

Conclusions
Fluid accumulation within striae distensae is a benign phenomenon, nevertheless, with a dramatic presentation. Awareness of this skin finding in patients with edema can prevent excessive and unnecessary interventions.
