Verrucous plaque on the back of a hand.

We report the case of a 44-year-old slaughter-house operator with a skin lesion that had been present for two years on the back of his left hand. The lesion had increased progressively in size despite numerous topical treatments. Physical examination revealed an infiltrated erythematous-violet plaque with a verrucous surface featuring numerous orifices draining purulent material.

Diffuse whitening of the oral mucosa in a child.

We report a healthy 16-year-old Caucasian boy, who consulted us for white, asymptomatic lesions in the mouth. The lesions were stable and had been present for 6 years. On physical examination, there were diffuse white, soft, corrugated plaques involving the buccal and labial mucosa, oral commissures, and floor of the mouth.

Juvenile xanthogranuloma.

Juvenile xanthogranuloma (JXG) is a benign, self-healing disorder characterized by solitary or multiple yellow-red nodules on the skin and, occasionally, in other organs. It is predominantly a disease of infancy or early childhood, although adults may also be affected. Histologically, JXG represents an accumulation of histiocytes lacking Birbeck granules (non-Langerhans cells), which can be differentiated from Langerhans cells by specific staining techniques.

[Results of 769 stapedectomies performed between 1975 and 1993].

A retrospective review was made of 719 primary stapedectomies and 48 re-operations carried out between 1975 and 1993. Preoperative and postoperative audiograms (6-12 months) were studied, analyzing 250, 500, 1000, 2000 and 4000 Hz, auditory gain and closure of the air-bone gap < or = 10 dB. Ninety percent had an auditory gain of > or = 10 dB at conversational frequencies.

[The influence of age and previous thresholds on stapedectomy results].

This is a retrospective study dealing with 719 primary stapedectomies and 48 reoperations done between 1975 and 1993 by the AA. of the paper. They consider the audiometric tracings before and after surgery (6 and 12 months).

'Scléroedème génito-sus-pubien' of the newborn: a forgotten disease?

A 2-month-old boy with an important hardening of the skin in the pubic and genital regions is presented. He was born prematurely at 31 weeks of gestation, and required a respirator during the first 72 h. The analytical explorations and abdominal ultrasound images were normal.

[Primary mucous melanoma of the nasal cavity: a case report].

Mucous melanoma in the nasal cavity are unusual tumours that develop from common melanocytes pre-existent in the respiratory epithelium. They manifest a high diagnostic and therapeutic difficulties as well as an obscure prognosis. A case of this rare tumour is exposed and a bibliographic review in which clinical, diagnostic, histological, therapeutic and prognostic features are contemplated.

[Study of 288 stapedectomies performed between 1986 and 1991].

A review of 288 stapedectomies performed between 1986 and 1991 was carried out. Pre- and post-surgical (within six to nine months) audiometries were studied, analyzing the 250 Hz, 500 Hz, 1,000 Hz, 2,000 Hz and 4,000 Hz frequencies. No significant differences between age and sex, type of prosthesis or final auditive gain were found.

[Intracranial invasion of a tumor of the ear].

A 55 years old woman with a neoplasm originating in ceruminous glands of the external auditory canal, with temporal bone and intracranial invasion, mimicking a glomus jugulare tumor. This group of neoplasms, rare in man, are best treated by and aggressive wide "en bloc" temporal bone and contiguos structures resection. In our review few similar cases are found.

[Malignant tumor of the external auditory canal].

The neoplasms from the modified apocrine glands of the external auditory canal are usually included under the term ceruminoma without any reference to their histology, clinical course or prognosis. It seems better to classify them according to their histologic pattern in the following types: 1.--Ceruminous adenoma, 2.

[Ethmoido-frontal mucocele. Apropos of a clinical case].

We presented a case of a 60 years old woman, with a previous history of an intervention upon the frontal sinus 35 years ago, who was diagnosed and operated at our service from mucocele of frontal sinus. We profit this occasion to carry through a revision of bibliography, to contribute at better knowledge of mucoceles about their clinic, pathogenic, diagnostic and therapeutic aspects.
