[Benign tumors of the soft tissue of the hand, about 70 cases]. / Les tumeurs bénignes des parties molles de la main, étude clinique à propos de 70 cas.

Through a retrospective study of 70 cases of benign soft tissue tumors in the orthopedic traumatology department of the military hospital of Tunis over a 12-year period from January 2005 to December 2016, we have compared our findings to those of the literature in an attempt to identify epidemiological notions relevant to daily medical practice as epidemiological data on benign tumors of the soft parts of the hand remain few and sometimes discordant. The authors report a series of 70 active, young adults, mostly female, with a swelling at the level of the hand as the most common reason for consultation. The middle finger and index finger were the most affected fingers at equal frequencies. The key supplementary examination was the ultrasound of the soft parts. All patients were treated with a complete surgical biopsy of their tumor followed by a histological study of the surgical specimen. Three cases of recidivism were noted. Through this study, the frequency of tumors of the soft parts of the hand in a particular population (Tunisian military agents) is emphasized. Moreover, this study allowed us to confirm the data of the literature concerning the dominance of the digital localization. On the other hand, this study reports that the giant cell tumor is the most common histological type in the study population.

[Multicentric giant cell tumor in the upper extremity]. / Tumeurs à cellules géantes à localisations multiples du membre supérieur.

Multicentric giant cell tumors of bone are rare; they represent less than 1% of all giant cell tumors. We report the case of a 24-year-old right-handed man, who presented in 1985 with a giant cell tumor of the upper end of the right humerus. After failure of conservative treatment (curettage and bone grafting), resection-arthrodesis of the shoulder with a free vascularised fibular autograft was performed. Three years later, the patient developed an osteolytic lesion of the lower end of the ipsilateral radius, involving the soft tissues and the wrist joint. He was treated with resection-arthrodesis of the wrist with a free vascularised fibular graft. View after 24 years for a new localization of the lower extremity of the humerus, which treated by curettage and bone grafting with a favorable postoperative (follow-up). The histologic study confirmed again the same diagnosis. After review of the literature, we report the uniqueness of this case report.
