An unusuai case of ovarian tumor E. A. BAMBIRRA

ovarian tumors have been associated with with or without systemic hypercalcemia: gonadoblastoma, teratoma/dermoid, dysgermininoma.1 The calcification in these tumors had irregular, confluent, or rounded pattern. In mature cystic teratoma we frequently have bone well formed, but this fact occurred in a focal area. 2 We report a case in which an ovarian osseous cyst was diagnosed at the pathologic examination. SEVERAL
calcific~tion,
A 42-year-old woman was admitted to the hospital with a pelvic calcified mass. She complained of abdominal pain, especially during sexual intercourse. An operation was performed and a right ovarian tumor, rounded, with no adhesiveness to neighboring structures, was excised. Pathologic examination of the specimen demonstrated a nodular tumor, 6.0 by 6.0 by 5.0 em. In cut-surface view this tumor was a cyst with osseous wall and yellow and limpid fluid (Fig. 1). A roentgenographic view demonstrated a consistent osseous matrix in the walls of the cyst (Fig. 2). Routine histologic examination, after decalcification, revealed compact and trabecular mature osseous tissue in iameiiar pattern (Fig. 3). Focal hematopoietic marrow tissue within osseous trabeculas was observed. No epithelial cells were identified in the tumor. The patient was well postoperatively.
In the case reported here we have an unusual ovarian cystic tumor. No similar cases could be found in the literature and we have no histologic elements to determine the pathogenesis of this tumor. Reprint requests: Eduardo Alves Bambirra, M.D., Rua Turmalina 274, 30.000 Belo Horizonte MG, BraziL
