RESUMO

Eighteen cases of massive ovarian oedema are presented. The age of patients averaged 26 years and 16 presented with an acute abdomen. Hormonal symptoms included virilism in three cases and one with precocious pseudopuberty. Ultrasonographic findings were variable and not diagnostically accurate. When performed, CA 125 levels were not raised. Seventy-two percent of cases occurred in the right ovary and none were bilateral. Torsion occurred in 14 cases. Salpingo-oophorectomy was performed in all cases. To elucidate its pathogenesis, be this either due to intermittent chronic torsion or to a proliferative phenomenon, immunohistochemistry for Ki-67 and PCNA proliferation antigens, alpha-actin and oestrogen and progesterone receptors was performed. The Ki-67 proliferation index ranged between 0% and 3%, demonstrating the low proliferative status of stromal cells. The PCNA indices, however, were unusually high (60% and above). The divergence between these findings is explained by the fact that PCNA positivity may be related to nuclear reparation subsequent to ischaemia. Alpha-actin was consistently positive in stromal cells, reflecting a myofibroblastic transformation of these cells. These findings together with the clinical evidence of torsion in the majority of cases, lead us to consider that ovarian oedema is a reactive, non-proliferative state of specific stromal cells, occurring as a response to torsion and subsequent ischaemia. The stromal cells have positive oestrogen progesterone receptors and may undergo stimulatory changes responsible for the hormonally related symptoms often found associated with massive ovarian oedema.

RESUMO

Five cases of intrauterine device (IUD)-associated tuboovarian actinomycosis are presented. The patients' ages ranged from 33 to 49 years and their IUD usage from 2 to 12 years. Clinical features of the cases included stenosis of the sigmoid colon in 4 cases, ureteric or bladder obstruction in two cases, and rectal fistula in a further instance. All patients were successfully treated postoperatively with penicillin or ampicillin. An initial diagnosis of ovarian carcinoma was considered in all cases. Although Actinomyces is difficult to differentiate histopathologically from microorganisms and other substances that cause the Splendore-Hoeppli phenomenon, morphological diagnosis permits a quicker and more practical approach than bacterial cultures in the establishment of postoperative antibiotic treatment. Intraoperative frozen-section diagnosis of an acute inflammatory process permits the surgeon to make an immediate decision in order to avoid extensive surgery when ovarian carcinoma is suspected.
