Про гистологические находки при болезни Де Кервена - британцы в 1998 писали, что нет признаков воспаления, а скорее дегенеративный процесс:
The condition was not characterized by inflammation, but by thickening of the tendon sheath and most notably by the accumulation of mucopolysaccharide, an indicator of myxoid degeneration. These changes are pathognomonic of the condition and are not seen in control tendon sheaths. The term 'stenosing tenovaginitis' is a misnomer and we believe that de Quervain's disease is a result of intrinsic, degenerative mechanisms rather than extrinsic, inflammatory ones.

The histopathology of de Quervain's disease.

позже в 2015, специалисты из Тайваня, таки находят воспалительные изменения:
Previous studies consistently reported that the pathological change of this condition is thought to be primarily an extensor retinaculum thickened by fibrosis and angiogenesis instead of inflammation...
Neutrophil elastase and cyclooxygenase occur in the de Quervain disease retinaculum and increased with the grade of collagen structure. After angiogenesis, macrophage infiltration occurs in the grade II matrix worse than grade III matrix.
Inflammation is present in de Quervain disease. This study provides direct evidence for inflammatory cell and infiltration factors and offer valuable clues for specific pharmacological therapies for de Quervain disease.
