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 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.

봉입체 섬유종증은 주로 1세 이내의 소아 수지 및 족지에 발생하는 무통성의 섬유성 연부조직 종양이다. 병리학적으로는 치밀한 방추형 세포로 이루어져 있으며, 세포질 내에 항산성 봉입체가 관찰된다. 종양은 자발적 퇴행을 하는 것으로 알려져 있으나, 변형이나 기능장애를 일으키는 경우 수술적 치료를 요하며, 수술하는 경우 약 60%에서 다시 재발하는 것으로 보고되고 있다. 저자들은 비교적 높은 연령의 소아 수지에서 발병하였으며, 술 후 접촉성 병변이 발견된 봉입체 섬유종증 1예를 보고하고자 한다.

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.
