Leiomyomatosis peritonealis disseminata in a postmenopausal woman.

Leiomyomatosis peritonealis disseminata (LPD), a multifocal proliferation of smooth muscle like cells, has so far been described in 48 cases. Most of them were pregnant women or women taking the oral contraceptives, which supported the hypothesis that LPD is associated with hyperestrogenism. We report a 65-year-old women, without history of taking exogenous estrogens, which suggests that factors other than hormonal influences may contribute to pathogenesis of LPD.

[Angiosarcoma of the breast--histopathologic and electron microscopy picture]. / Angiosarkom dojke--patohistoloska i elektronskomikroskopska slika.

The authors describe angiosarcoma of the right breast, together with the pathohistologic and electron microscopic analysis and survey of the literature of this rare tumor. The greatest tumor diameter was 4.5 cms. Mastectomy and the axilla's dissection was performed and additionally, radiotherapy was undertaken. In the first biopsy the wrong diagnosis of ductal invasive carcinoma was made. Three years later a metastasis appeared in the left axilla when angiosarcoma was established. The revision of primary tumor of the right breast showed that previously it was angiosarcoma of the right breast, too. In this article the authors direct attention to the possibility of wrong diagnosis of benign or malignant tumor and list the results taken from the world literature. Following those results, the wrong diagnoses were made in 37% of the cases with breast angiosarcoma.
