[Epidemiology of HPV infection].

HPV DNA testing using Hybrid Capture 2 (Digene) was added to a program of liquid based (Thinprep, Cytyc) cervical cancer screening in a population of sexually active women aged from 20 to 62 years, without the history of uterine cervix pathology. 14.32% of 3832 women in this population were HPV positive. Positivity peaked in women aged 25-29 (19.4%) and gradually decreased, with 8% of positivity after 60 years. Positivity was independently related to parity, tobacco use and was correlated to cervical pathology. The rate of positivity in this population seems to preclude the use of HPV testing as a primary screening tool.

[Cellular neurothekeoma, a rare cutaneous tumor. Anatomo-clinical and immunohistochemical study of 2 cases].

Cellular neurothekeoma is an unusual cutaneous tumor described in 1986. We report two new cases in 14-year-old girls. Both tumors measured less than one centimeter and were located on the forearm and the shoulder. They had a plexiform architecture and were developed in the dermis and the dermo-hypodermic junction. Spindle and epithelioid tumor cells were immunoreactive for vimentin, NKI-C3, NSE, CD68 and smooth muscle actin. There was no recurrence 2 and 7 months after the operation. Cellular neurothekeoma is a benign tumor. Its histogenesis is still unknown. Histological and immunohistochemical features, with positivity of the tumor cells for NKI-C3, a non specific melanocytic marker, and negativity for S-100 protein and HMB-45, allow to differentiate cellular neurothekeoma from myxoid neurothekeoma and melanocytic tumors.

[Mesothelial cyst of the adrenal gland].

We report a case of a mesothelial adrenal cyst which was incidentally discovered in a 38-year old woman. The diagnosis was confirmed by an immunohistochemistry study. Adrenal cysts are rare. They occur more commonly in female patients during the 4th and 5th decades and are usually asymptomatic. Adrenal cysts are divided into four groups : parasitic, epithelial, endothelial cysts and pseudocysts. The management is still discussed : follow-up, surgical resection or fine-needle aspiration.

[Plurifocal testicular hamartomas and testicular feminization syndrome].

We report the case of a 14-year-old girl with a testicular feminization syndrome. The inguinal cryptorchid testis contained plurifocal hamartomas ranging from 0.5 to 1 cm. They were composed of tubules lined by cylindrical Sertoli cells immunoreactive for alpha-inhibin and p30/32(MIC2). The stroma contained few Leydig cells. Ultrastructural study showed tubules with immature Sertoli cells. The testicular feminization syndrome is caused by mutations of the androgen receptor gene. Patients with male genotype 46, XY have a female morphotype with external sexual organs without ambiguity. They have neither uterus nor ovary but two cryptorchid testis in which sex-cord stromal tumors can develop. Their malignant transformation is rare but requires preventive bilateral orchidectomy.
