ABSTRACT
Massive Ovarian Edema (MOE) is a rare cause of ovarian enlargement. Only 77 cases have been reported in the world literature so far, merely three of which were observed during pregnancy. Two of these showed additional pathological changes of the affected ovary (torsion) or were found in twin pregnancy. The patient presented on hand is therefore only the second report of MOE in an uncomplicated singleton pregnancy. In this case, a therapeutical resection of the affected ovary was performed at 16 + 4 weeks of gestation. The further course of the pregnancy was uncomplicated.

We report on a 51-year-old male patient showing a slowly growing, pedunculated, hairless tumor on the back of his head. The tumor grew up to the size of 4.2 cm in diameter, before it was removed by surgery. Histological examination revealed the typical picture of an ancient schwannoma (degenerated neurilemmoma). In spite of its highly atypical nuclei, the biological behavior of ancient schwannoma is benign, and it must be differentiated from malignant tumors of the nerve sheath.
