Vascular and connective tissue histopathologic alterations of the female lower genital tract in scleroderma.
OBJECTIVE
It has been suggested that women with scleroderma (systemic sclerosis, SSc) have cervical changes that may lead to obstetrical or postoperative complications. We evaluate histopathologic features characteristic of SSc in cervicovaginal tissue from women with SSc and compare them to age matched controls.


METHODS
Records from the Scleroderma Registry at Wayne State University were matched with surgical specimens in the anatomic pathology files at Hutzel Hospital. Five women with SSc (2 with limited SSc, 3 with diffuse SSc; mean age 49 yrs) were identified who had cervical or vaginal tissue specimens available for evaluation. Small arterioles and surrounding connective tissue in these specimens and those from 26 age matched controls (15 normotensive, 11 hypertensive) were evaluated in blinded fashion.


RESULTS
The following specific histopathological features were evaluated in the SSc patients: duplication or disruption of the internal elastica in 5 (100%), medial hypertrophy in 5 (100%), adventitial changes in 3 (60%), connective tissue fibrosis in 1 (20%), and vasculitis in 1 (20%). There was no significant difference in the frequency of the histopathologic changes between SSc and control patients when evaluated independently. However, the presence of 3 or more features was significantly more frequent in the SSc patients (100%) than in the controls (38%) (p = 0.018).


CONCLUSIONS
The histopathological features evaluated were collectively more frequent in SSc patients; however, many of the control patients also exhibited similar abnormalities. In the female lower genital tract these changes, previously attributed solely to SSc, may be related to other factors.
