Linear Scleroderma and Primary Sclerosing Cholangitis: An Undescribed Association

Linear scleroderma (LS) is clinically characterized by the presence of sclerotic areas of skin, which develop in a linear pattern. Primary sclerosing cholangitis is a cholestatic disorder that can lead to end-stage liver disease. We present, for the first time in English literature, the case of a patient suffering from both the diseases. This highlights the fact that, even though LS has conventionally been considered to be a form of localized scleroderma, this does not necessarily imply that it is an exclusively cutaneous disease.

Morphea and antithyroid antibodies

Introduction

Morphea, also known as localized scleroderma, is an autoimmune skin disease which is characterized by excessive accumulation of collagen that leads to the thickening of the dermis and subcutaneous tissue. There is an unclear relationship between morphea and other autoimmune diseases, especially related to the thyroid gland.

Aim

To determine the occurrence of increased antithyroid antibodies in patients with morphea in relation to the clinical manifestations of the disease.

Material and methods

Forty-two Caucasian patients with different forms of morphea were included into the study. To determine the thyroid status, thyrotropin (TSH), anti-peroxidase antibodies (TPO-Ab), anti-thyroglobulin antibodies (Tg-Ab) were evaluated with the use of the electrochemiluminescence method and TSH receptor autoantibodies (TRAb) – with the use of the radioimmunoassay method.

Results

Increased levels of antithyroid antibodies were observed in 6 cases in relation to TPO-Ab (14.3%), in 4 cases in relation to of Tg-Ab (9.5%) and in 1 patient in relation to TRAb (2.3%). There was no difference in the level of antithyroid antibodies between circumscribed and generalized forms of morphea.

Conclusions

Although morphea is an autoimmune disease, it does not seem to be associated with increased prevalence of positive antithyroid antibodies. We conclude that there is no need to perform routine laboratory tests for thyroid disorders in patients with morphea.

Concurrence of Circumscribed Morphea and Segmental Vitiligo: A Case Report

Although a few reports have noted the concurrent presentation of morphea and vitiligo at distinctly separate sites in the same patient, it is extremely rare that these two conditions occur at the same sites in a patient. We report the case of a 10-year-old Korean girl with morphea and vitiligo and those lesions occurred at the same sites and progressed simultaneously. An autoimmunity and a cutaneous mosaicism was considered to be involved in such an unique presentation as the pathogenesis is concerned.

Distinct autoimmune syndromes in morphea: a review of 245 adult and pediatric cases

OBJECTIVE

To determine the prevalence of extracutaneous manifestations and autoimmunity in adult and pediatric patients with morphea.

DESIGN

A retrospective review of 245 patients with morphea.

SETTING

University of Texas Southwestern Medical Center-affiliated institutions. Patients Patients with clinical findings consistent with morphea.

MAIN OUTCOME MEASURES

Prevalence of concomitant autoimmune diseases, prevalence of familial autoimmune disease, prevalence of extracutaneous manifestations, and laboratory evidence of autoimmunity (antinuclear antibody positivity). Secondary outcome measures included demographic features.

RESULTS

In this group, adults and children were affected nearly equally, and African Americans were affected less frequently than expected. The prevalence of concomitant autoimmunity in the generalized subtype of morphea was statistically significantly greater than that found in all other subtypes combined (P = .01). Frequency of a family history of autoimmune disease showed a trend in favor of generalized and mixed subgroups. The linear subtype showed a significant association with neurologic manifestations, while general systemic manifestations were most common in the generalized subtype. Antinuclear antibody positivity was most frequent in mixed and generalized subtypes.

CONCLUSIONS

High prevalences of concomitant and familial autoimmune disease, systemic manifestations, and antinuclear antibody positivity in the generalized and possibly mixed subtypes suggest that these are systemic autoimmune syndromes and not skin-only phenomena. This has implications for the management and treatment of patients with morphea.
