Lymphangioleiomyomatosis (LAM) is a rare lung disease affecting almost exclusively young women, characterised by abnormal proliferation of atypical smooth muscle cells. We describe a young woman presenting with chyluria secondary to the presence of a large retroperitoneal lymphangioleiomyoma. Immunohistochemical analysis revealed HMB45-negative LAM cells (HMB45 staining is absent only in rare cases) expressing low levels of estrogen receptors. Estrogen suppressive treatment with triptoreline, a synthetic analogue of Gn-RH, resulted in dramatic reduction of the retroperitoneal mass size. The role of estrogens in the pathogenesis of LAM remains poorly understood, and hormonal therapy is still debated, but this case suggests that at least in some LAM patients, possibly those with HMB45-negative disease and estrogen receptor expression, hormonal therapy may be effective in controlling the disease process.
