Fibromatosis colli is a benign fibrous tissue proliferation of sternocleidomastoid muscle, which is usually observed during the first month of life, often associated with congenital torticollis. It should be differentiated from other neck masses in infants because the usual initial treatment of fibromatosis celli is conservative management and invasive therapy should be avoided. Fine needle aspiration cytology provides an excellent minimally invasive diagnostic way for evaluation of infantile neck masses. We describe three cases of fibromatosis colli diagnosed by fine needle aspiration cytology. All of them were younger than one month and presented as a neck mass. Clinical impressions were malignant tumors in two cases and fibromatosis colli in one case. Fine needle aspiration cytology revealed benign and mature fibroblasts and atrophic striated muscle fibers. The cytologic diagnosis was fibromatosis colli or benign fibous lesion.

Plantar fibromatosis is a benign fibroproliferative disorder of plantar fascia with rare incidence, but there are locally invasive tendency. There has been no reports of the treatment of recurrent plantar fibromatosis and its complication except only 2 report about the plantar fibromatosis in Korea. Hereby we report three cases of recurrent plantar fibromatosis including treatment and complication.

A mass excision surrounding the bronchial stump was performed to exclude malignancy in a 42-year-old man who had undergone a right lower lobectomy for lung cancer. The mass was identified as a cicatricial fibroma. Cicatricial fibromatosis, which is desmoid fibromatosis that arises in a surgical scar, is a well-known clinical condition. It consists of histologically benign neoplasms. Their occurrence after thoracic surgery is extremely rare. Biopsy or excision of suspicious lesions is very important for diagnosis. R0 resection remains the principal outcome for intrathoracic desmoid fibromatosis. We report that a cicatricial fibromatosis in the subcarinal space was removed after suspicion of local recurrence at the bronchial stump follwing lobectomy for lung cancer.

The fibromatosis is a rare tumorous with local invasion, but is not metastasized distantly. This term should not be applied to nonspecific reactive fibrous proliferations that are part of an inflammatory process of are secondary to injury of hemorrhage and have no tendency toward growth or recurrence. It arises principally from the connnective tissue of muscle and overlying fascia or aponeurosis(musculaponeurotic fibromatosis), and chiefly affects the muscle of shoulder, pelvic girdle, and extremity. The term 'aggressive fibromatosis' is also employed to describe this disease, but it is impossible to predict the clinical course in the individual case. The fibromatosis arising in the mediastinum is very rare, and the report about it is nearly absent. The plain radiography shows merely mass with soft tissue density. The CT demonstrates a poorly defined homogenous or heterogenous mass, isodense with skeletal muscle on precontrast-images, and slightly hyperdense to muscle on postcontrast-scan. Accurate delineation between the tumor & surrounding tissue is vague or frequently impossible. The authors experienced one case of the mediastinal fibromatosis recently and report the case with review of concerned literature.

Fibromatosis is a broad group of benign fibroblastic proliferation that shows locally aggressive growth but never metastasize. Common anatomic sites include abdominal wall, extremity, and mesentery. Little is reported about clinical features and outcome of fibromatosis of the head and neck. The treatment of choice is wide excision, which is often difficult. Postoperative recurrence rates are high. We recently confirmed a unique case of fibromatosis occurred on the hypopharynx of 44-year-old male patient and report this interesting case with review of literature.

The fibromatoses are defined as a group of non encapsulated, non metastasizing, fibrous tumors that have a tendency for infiltrative growth and local recurrence following surgical excision and can be divided into fascial and musculoaponeurotic fibromatoses. Infantile fibromatosis is childhood counterpart of musculoaponeurotic fibromatosis and is more common in the head and neck, the shoulder and upper arm and the thigh. Treatment includes excision, radiation, steroid and chemotheraphy, etc. Treatment of choice is complete excision but postoperative deformity and sequelae should be considered. Recently, we have experienced a case of infantile fibromatosis originating from infratemporal fossa and report this case with a review of literatures.

Fibromatosis is benign fibroblastic proliferative lesion with abundant collagenous neo-formation located principally in the abdominal wall and in the upper and lower extremities (Masson & Soule, 1966). Wilkins and Waldron, in 1975, suggested that the title aggressive fibromatosis was a more appropriate term, reflecting the invasive characteristics of the disease. Synonyms listed were extra-abdominal desmoid, juvenile fibromatosis, aggressive infantile fibromatosis and congenital fibrosarcoma. A total of 12% of all fibromatosis arise in head and neck. Fibromatosis of the oral cavity is uncommon and is even more rare when in involve the mandibule. It is a locally aggressive fibrous tissue tumor, generally does not metastasize, but may cause considerable morbility and even death due to local infiltration. The degree of microscopic cellularity is variable, not only from tumor to tumor but also from area to area in the same tumor. Some tumors present with proliferation of mature fibroblasts and a dominating collagenous component : others may show a lack of the tumor in both types. The common histologic denominator appears to be cellular interlacing bundles of elongated fibroblasts, showing little or no mitotic activity and no pleomorphism. Mitosis are not a consistent index of malignancy when found in younger age groups. Fibromatosis still posses difficult problems of diagnosis and treatment. It is frequently recurrent and infliltrates neighbouring tissues. These lesion infliltrate widely and replace muscle, fat, and even bone with fibrous tissue of varying cellularity. Lesion representing fibromatosis in the oral cavity must be carefully evaulated by both surgeon and pathologists to ensure proper diagnosis and treatment planning. When these lesions involve bone, surgeon must be aware of the lesion's potential to perforate the cortex and expand while remaining hidden from the surgeon's view. Careful and precise clinical correlation with histologic appearance is essential to preclude misdiagnosis of fibrosarcoma yet provide surgical treatment plan that provides adequate local excision and long-term follow up. As regards cause, little is known. It is attributed to trauma or alteration in the sex hormone(Carlos, et al, 1986). Clinially, the lesion is reported to be not painful in most cases, but capable of rapid growth. The treatment is essentially surgical excision with wide margin of adjacent uninvolved tissue. Radiotherapy, hormone treatment or chemotherapy are of no use (WIkins et al, 1975 ; Majumudar and Winiarkl, 1978). We report a case of aggressive fibromatosis of 15-year-old with a lesion in the soft tissue of the parotid area that invaded the underlying bone of the mandibular body.

Objective: To demonstrate the feasibility of percutaneous microwave ablation in desmoid fibromatosis with respect to tumor volume control and improvement in the quality of life. Materials and Methods: Twelve microwave ablations were performed in 9 patients with a histological diagnosis of desmoid fibromatosis between January 2010 and January 2019. The study population included 6 female and 3 male, with an age range of 21-76 years (mean = 46.6 years; standard deviation [SD] = 19.3 years). The mean major axis of the tumors was 10.9 cm (SD = 5.2 cm) and mean lesion volume was 212.7 cm³ (SD = 213 cm³). Their anatomical distribution was as follows: 3 lesions in the thigh, 2 in the gluteus, 2 in the leg and 2 in the periscapular region. We evaluated the reduction in tumor volume and improvement in the quality of life based on the Eastern Cooperative Oncology Group (ECOG) scale. Results: An average tumor volume reduction of 70.4% (SD = 24.9) was achieved, while the quality of life (ECOG scale) improved in 88.9% of patients. Conclusion: Percutaneous microwave ablation may potentially be a safe, effective, and promising technique for controlling tumor volume and improving the quality of life in patients with desmoid fibromatosis.

Fibromatoses, a broad group of fibrous proliferations of similiar microscopic appearance, show intermediate biological behavior between benign fibrous lesion and fibrosarcoma. they are characterized by the infiltrative growth and the tendency toward recurrence, but they never metastasize. The mediastinal fibromatosis has been extremely rarely reported. We experienced a case of anterior mediastinal fibromatosis ingrowing onto the anterior chest wall in 2-year-old female. A radical surgical resection and anterior chest wall reconstruction was performed successfully.

공격성 섬유종증은 비교적 드문 연부 조직 종양이지만, 국소 증식 및 침윤성이 강한 종양으로 알려져 있다. 그렇지만 종양 증식에 관한 정확한 기전은 아직 보고되어 지지 않고 있다. 한편, 종양 억제 유전자 PTEN은 국소 침윤성과 전이를 보이는 여러 암 조직에서 발현의 감소 또는 돌연 변이가 보고되고 있다. 본 연구에서는 공격성 섬유종증에서 면역조직화학적 염색과 면역탁본법을 통해 종양 억제 유전자 PTEN의 발현의 양상을 알아보고자 하였다. 면역 탁본법과 면역조직화학적 염색상 PTEN의 발현은 정상 근막 조직에서는 균일하게 발현되었으나, 공격성 섬유종증 종양조직에서는 발현이 감소하였다. 공격성 섬유종증에서 PTEN발현의 감소는 급속한 증식과 재발 및 주위 조직의 침윤이 특징인 공격성 섬유종증의 병인에 관련이 있을 것으로 사료된다.
