A glomus tumour is a rare tumour of the hand, which presents with a classic triad of symptoms of temperature sensitivity, pain, and localised tenderness. We report a series of 14 patients with glomus tumours in the subungual region. There were four men and 10 women, whose mean age was 46 years (range 28-65). All patients complained of pain and localised tenderness and six of temperature sensitivity. The bony lesion was seen on radiographs in four patients. We used a transungual approach in all cases. A detailed history and clinical findings are the best way of making the diagnosis. The treatment of glomus tumour consists of complete excision and repair of the nailbed. Inadequate excision of the tumour usually causes local recurrence.

The distribution of bone and soft tissue tumors appear to have certain characteristics but can show regional differences. We believe that the establishment of a larger series through the collection of these types of studies from centers in which bone and soft tissue tumor surgery is performed will provide important information on the epidemiological features of bone and soft tissue tumors.

The objective of this study was to present a simple, convenient, and reliable technique for the application of liquid nitrogen and to evaluate the effectiveness of curettage and cryosurgery. Between 1992 and 2002, 24 patients who had benign aggressive and low-grade malignant bone tumors were treated by curettage and cryosurgery. While cryosurgery was applied by the "direct pour" technique in the first seven patients, it was applied by the "pressurized spraying" technique in the others. Functional results were graded according to Enneking. The mean follow-up was 47 (range 9−131) months. There were no local recurrences. Three patients who underwent the direct pour technique developed partial skin necrosis. The functional results were excellent in 14 patients, good in six, and fair in four. When compared with previous reports on cryosurgery and its application techniques, we detected no tumor recurrence or complications, including soft-tissue injury, infection, and late fracture with liquid nitrogen applied by the pressurized spraying technique.Résumé L'objectif de cette étude était présenter une technique simple, pratique et fiable pour l'application d'azote liquide et évaluer l'efficacité du curetage avec cryochirurgie. Entre 1992 et 2002, vingt-quatre malades qui avaient des tumeurs osseuses bénignes agressives ou des tumeurs malignes de bas grade ont été traités par curetage et cryochirurgie. Cette cryochirurgie a été appliquée par versement direct chez les sept premiers malades, et par une technique de vaporisation chez les autres. Les résultats fonctionnels ont été notés d'après Enneking. Le suivi moyen était de 47 mois (9 −131). Il n'y avait pas de récidive locale. Trois malades qui ont subi le versement direct ont développé une nécrose cutanée partielle. Les résultats fonctionnels étaient excellents pour 14 malades, bons pour six, et médiocres pour quatre. En comparant avec les précédentes publications nous n'avons retrouvé ni récidive de la tumeur ni les complications incluant l'atteinte des parties molles, l'infection ou la fracture tardive lorsque l'azote liquide a été appliqué par la technique de vaporisation.

Pilomatrixoma is a rare benign skin tumor arising from hair follicle stem cells which is also known as calcifying epithelioma of Malharbe. It occurs with a rate of 0.1% among skin tumors. The definite diagnosis is made histopathologically. In treatment, it is recommended that the lesion be excised surgically. In this study, we wished to present two patients who presented with swelling and underwent excisional biopsy as a result of magnetic resonance imaging and whose pathological result was reported to be pilomatrixoma in accompaniment with the literature.
