[Giant form of infantile myofibromatosis located on the jaw].

INTRODUCTION: Infantile myofibromatosis is a rare fibrovascular-like tumour, characterized by the development of single or multiple nodular lesions arising from cutaneous, subcutaneous, muscular bone or visceral structures, diagnosed before 2 years. OBSERVATION: We report a case of infantile myofibromatosis located on the jaw, which is unique because of its large size (12 cm), its location and its neonatal presentation. It was a voluminous proliferate tumour with an ulcerated centre, located on the left jaw. Surgical excision was complete and the diagnosis was maded on histological examination. Recovery was uncomplicated with no recurrence on follow up. DISCUSSION: Diagnosis of infantile myofibromatosis is difficult because of the clinical heterogeneity and the histopathological appearance. The histological diagnosis relies on identification of two separate components, fascicular myofibroblastic at the periphery and hemangiopericytome in the centre. The most freqaent treatment is conservative surgical excision, because recurrence rates are low and there is a possibility of spontaneous regression. Some authors recommend conservative management of very large or multiple lesions particularly if excision will result in significant functional or cosmetic morbidity.

Ectopic lingual thyroid.

Ectopic lingual thyroid is an uncommon embryological aberration characterised by the presence of thyroid tissue located in a site other than the normal, pretracheal region. The tongue is the most frequent ectopic location of the thyroid gland; the clinical incidence of lingual thyroid varies between 1:3000 and 1:10,000. We present a new case of lingual thyroid in a 10-year-old child who presented dysphagia. The radiological findings and the biopsy confirmed the diagnosis. As the mass was well tolerated, surgery was not indicated. At this time, there are no signs of complications or malignant transformation.

[The bilobed flap: a very efficient method in aesthetic reconstruction of small skin defects at the alar and tip regions of the nose].

From October 1996 to January 2001, 20 patients (14 men and six women) ranging from 36 to 75 years old have been treated for their small skin defects of the nose by using the bilobed flap. These skin defects were located in 15 cases at the alar region and in five cases at the tip region. They were secondary to the resection of basal cell carcinoma in 17 cases and benign tumors in three cases. Their diameter ranged from 8 to 17 mm and in all these cases there was no involvement of the lining or cartilage. The design used for this bilobed flap was the Zitelli one, based on some mathematical principles; its base was medial or lateral depending on the site of the defect. With this method, the skin defects were reconstructed esthetically without any distortion of local anatomy of the nose with skin having the same color, texture and thickness. With an average of 28 month follow-up, all these reconstructions were stable with discreet scars and without the trapdoor phenomenon. No complications were reported. Esthetic reconstruction of such subunit nasal skin defects is easily done by this technique and is better than that obtained by the majority of others methods.

[Reconstruction of large scalp and calvarium defects by using the semi-free latissimus dorsi flap associated with methylmethacrylate implant for cranioplasty].

The semi free latissimus dorsi flap is characterized by a temporary vascular anastomosis on a pedicle not belonging to the loco-regional anatomy of the skin defect; after a period of autonomy, the section of the flap pedicle is obligatory. Its advantage compared to the classic free flap is the great microsurgical security avoiding complex, and stressful supervision in the postoperative period. From June 1998 to January 2001, 7 patients ranging from 18 to 65 years old and suffering from large scalp defects going between 20 x 13 cm and 27 x 18 cm have benefited from this surgical method. The etiology of these defects was: in 4 cases dermatofibrosarcoma protuberans involving the periost, in 1 case destruction of the near entirety of the scalp and calvarium by electrical burn, in 1 case an instable scar of burn with osteomyelitis and in the last case an osteomyelitis on a frontal cranioplasty. Three stages have been used:--The thoraco-dorsal artery was anastomosed on the wrist to the radial artery in a termino-lateral way and the thoraco-dorsal vein to the superficiel radial vein in a termino-terminal way;--The flap was fixed to the forearm for 2 weeks, then, the debridement which has always exposed the dura was done; The flap was sutured to the defect after reconstruction of calvarial defect with the méthylmétacrylate implant;--After 3 weeks the pedicle was sectioned and the flap tailored exactly to the defect. No postoperative complications were reported. With a mean follow-up of 18 months, the scalp coverage was very satisfactory.
