    ABSTRACT: Syndromes with focal overgrowth are sporadic diseases and comprise Proteus syndrome and congenital lipomatous overgrowth, vascular malformations, and epidermal naevi (CLOVE) syndrome, and isolated hemihyperplasia. We describe 3 children classified according to standard criteria with dysregulated growth of various tissues that was excised, together with excess toes, and tumours. Correct classification facilitates diagnosis and operations. Interdisciplinary treatment and follow-up are recommended to prevent disfiguration.

    ABSTRACT: Aggressive fibromatosis, e.g., desmoid tumour, is a rare neoplasm of the connective tissue with local infiltrative growth. Because of the high recurrence rates and destruction of the surrounding tissue, these tumours are classified as semi-malignant. However, desmoid tumors tend not to metastasise. Arising from deep musculoaponeurotic structures, a monoclonal proliferation of fibroblasts occurs. Radical surgical treatment with tumour excision accompanied by radiotherapy is the current standard therapy that can be supplemented by pharmacological treatment in a few cases. We report on 9 patients (5 males and 4 females) with surgical therapy for aggressive fibromatosis. The neoplasm was located on the extremities in 7 cases (4 x upper extremity, 3 x lower extremity), one tumour was situated in the chin and one in the rectus abdominis muscle. All patients were treated with radical tumour resection. Postoperatively, adjuvant radiotherapy was performed depending on the resection level of each patient. In 6 cases complete tumour resection (R0) was achieved. Following surgery, regular follow-ups with a physical examination and MR images were performed. In 3 cases a total tumour resection was impossible (R1 resection). The aggressive fibromatosis had infiltrated the pelvis in 2 cases implying a hemipelvectomy for R0 resection which was not practicable. Furthermore, diffuse locoregional infiltration of the chin region occurred in one case. In these cases, an adjuvant radiotherapy with 25 x 2 Gy was started postoperatively after the accomplished wound healing. Treatment with chemotherapeutic agents was not necessary. Aggressive fibromatosis is a semimalignant neoplasm of the connective tissue with an extremely high recurrence rate. Macroscopically, indistinct solid lesions are found with the destruction of muscles and other surrounding structures. Therapy of choice is the radical surgical resection. Radiotherapy is indicated for patients with non-resectable tumours. Pharmacological treatment should be considered for patients with unsuccessful local therapy.

    ABSTRACT: Systemic treatment with chemotherapeutic agents is often applied by infusions over peripheral vein cannulae located on the hands and lower arms. Dislocation of the cannulae or vein perforation causes an extravasation of the cytostatic agent. This complication occurs in approximately 0.1 - 6 % of intravenous treatments and is rarely noticed before administration of greater volumes. Depending on the tissue toxicity of the administered substances, the extravasation results in tissue damage of different extents. In a few cases, only conservative therapy is required. The majority of patients, however, needs immediate surgical therapy. The reason for this is the severe tissue damage caused by the chemotherapeutic agent that accumulates in the subcutaneous fat where it destroys the connective and fat tissue, nerves, vessels, tendons and muscles, impairing the functionality of the entire hand and arm. In very severe cases, partial or complete amputation of the extremity is the only treatment. The application of antidotes has been discussed controversially and is not a standard procedure. In the past 11 years, 18 patients with extravasations of chemotherapeutics on the dorsum of the hand were admitted to our department. After radical debridement no primary closure of the resulting defect was advisable in the first operation. In all cases we could later perform a stable wound closure. In our opinion, this two-step procedure with primary radical debridement, temporary wound coverage and later wound closure should be performed regularly.
