Giant angiomyoma of the broad ligament

Abstract

vascular component, haemangiomas, and adenomatoid tumour. Microscopically, ovarian lymphangiomas are multicystic to cavernous lesions consisting of multiple closely packed lymphatic vascular spaces of varying sizes lined by bland appearing, flattened endothelial cells. The stroma is formed by fibrocollagenous tissue infiltrated by rare lymphocytes. The lymphatic endothelium frequently shows expression of factor VIII-related antigen, CD34, and CD31. These may help in differentiation of difficult cases to reach the correct diagnosis (Akyildiz et al. 2006). Histologically, the lymphangioma is typically benign, despite the seemingly infiltrative growth and multicentricity. Recurrences after incomplete excision and mechanical complications may simulate malignancy. Malignant transformation is very rare with death reported in one case (Kroemer 1908). The malignant potential of this lesion is still unknown as a result of the paucity of cases (Rice et al. 1943). Surgical excision is curative, however radiotherapy has been used in surgically non-resectable lesions (Rice et al. 1943). Because of the rarity and lack of specific gross and imaging findings, the diagnosis of ovarian lymphangioma is unexpected preoperatively and therefore histopathological examination is essential for all cystic lesions of ovary supported by immunohistochemistry wherever required.
