RESUMEN
Disseminated peritoneal leiomyomatosis (DPL) is a rare variant of extrauterine leiomyomatosis with reported spontaneous and iatrogenic occurrences. It has been associated with hysterectomy and myomectomy. To our knowledge, reports have not yet substantiated occurrence following uterine artery embolization (UAE), which has become a routine minimally invasive alternative to surgery for the treatment of symptomatic leiomyomata. This report presents the case of a nulliparous premenopausal woman with no other contributory history who presented with DPL 3 years after UAE. The presentation of this patient suggests the potential for a causal relationship between UAE and DPL.

Registry data worldwide indicate an overall female predominance for pulmonary arterial hypertension (PAH) of 2-4 over men. Genetic predisposition accounts for only 1-5% of PAH cases, while autoimmune diseases and infections are closely linked to PAH. Idiopathic PAH may include patients with undiagnosed autoimmune diseases based on the relatively high presence of autoantibodies in this group. The two largest PAH registries to date report a sex ratio for autoimmune connective tissue disease-associated PAH of 9:1 female to male, highlighting the need for future studies to analyze subgroup data according to sex. Autoimmune diseases that have been associated with PAH include female-dominant systemic sclerosis, systemic lupus erythematosus, rheumatoid arthritis, Sjögren's syndrome, and thyroiditis as well as male-dominant autoimmune diseases like myocarditis which has been linked to HIV-associated PAH. The sex-specific association of PAH to certain infections and autoimmune diseases suggests that sex hormones and inflammation may play an important role in driving the pathogenesis of disease. However, there is a paucity of data on sex differences in inflammation in PAH, and more research is needed to better understand the pathogenesis underlying PAH in men and women. This review uses data on sex differences in PAH and PAH-associated autoimmune diseases from registries to provide insight into the pathogenesis of disease.
