Striae Distensae
Pronunciation: STRY-ee dis-TEN-see
Linear atrophic scars of the dermis caused by rapid stretching or hormonal changes, commonly called stretch marks.
Full Definition
Striae distensae are linear, atrophic dermal scars resulting from rapid changes in body size (pregnancy, obesity, adolescent growth spurts) or prolonged corticosteroid exposure. Fresh striae (striae rubrae) are erythematous or violaceous; older striae (striae albae) are pale and atrophic. The correct Latin plural is 'striae distensae' (nominative plural); the singular is 'stria distensa.' Editors should flag the common error of writing 'striae' as the singular form. The lay term 'stretch marks' is acceptable in patient information leaflets but should not replace the clinical term in academic or clinical documents.
Usage
Usage note: 'Striae' is the Latin plural; the singular is 'stria.' Do not write 'a striae' or 'striaes.' Use 'stretch marks' only in lay/patient-facing documents.
