ABSTRACT
The chorionic villous vascularization of 40 patients with first trimester spontaneous abortion was compared with that of 10 patients undergoing legal abortion (control group). The spontaneous abortion group was subdivided into a group with intrauterine embryonic death (n = 20) and a group with blighted ova (n = 20). Villous vascularization appeared unaffected after prolonged postmortem intrauterine retention. The incidence of vascularized villi was 89% in the control group, 26% in the group with embryonic death, and 9% in the group with blighted ova. In addition, the vascular density of vascularized villi was three to four times higher in the control group than in the two spontaneous abortion groups. The present study provides evidence that, in case of embryonic death and blighted ova, chorionic villous vascularization is deficient.

An epidermoid cyst of the testis is a rare benign lesion, representing about 1% of all testicular tumors. Most of the lesions occur between the age of 20 and 40 and present as a painless enlargement of the testis, or are found as a nodule on routine examination. Histopathologic findings consist of a cyst filled with keratin and lined by a squamous epithelium. There is evidence that this tumor is of germ-cell origin and represents monoepidermal differentiation of a benign teratoma. There is some discussion about treatment, but most authors perform radical orchiectomy.

Regional odontodysplasia was diagnosed in a girl aged 6 with lesions of a number of deciduous and permanent teeth in the right lower and upper quadrants. The literature comprises reports on some 50 cases of regional odontodysplasia, including only one patient who also showed involvement of both the maxilla and the mandible.
