Two cases of fibromatosis are presented. The lesion was biopsied and diagnosis was confirmed by histologic examination. Some reviews with literatures are supplemented.

The purpose of this study was to know the proper diagnosis and to establish the treatment plan of cementifying and ossifying fibroma in the jaws through the clinical, raiological, and histopathologic considerations. The authors compared and analyzed the clinicoradiologic features of the thirteen cases of cementifying and ossifying fibroma, diagnosed at the Dental college hospital in Yonsei university, Seoul, Korea, during the period from 1980 to 1995. The obtained results were as follows: 1. Cementifying and ossifying fibroma occured in the mean age, 44 years, ranged from 29 to 65 years and the male to female ratio was approximately 1:5. 2. Swelling was the most common frequent presenting complaints. Other reported symptoms included pain, tooth mobility and asymptom. 3. The frequency of the lesions was twelve cases in the mandible and one case in the maxilla. And eleven of thirteen cases were distributed on the premolar and molar region. 4. Radiologically, eight of thirteen cases were well defined lesions, five cases were relatively well defined lesions. And nine of thirteen cases were mixed lesions, three cases were radiopaque lesions, and only one case was purely radiolucenct lesion. 5. Histologically, seven of thirteen cases were classified ossifying fibroma, four cases were cemento-ossifying fibroma, and two cases were cementifying fibroma.

The authors experienced one case of peripheral giant cell granuloma occurred at the gingiva of right maxillary molar in a 12-year-old male patient. The lesion showed amorphous calcification within soft tissue mass which made difficult to differentiate this lesion from peripheral ossifying fibroma and peripheral odontogenic fibroma clinically and radiographically. The final diagnosis was made histologically.

This case was diagnosed as multiple cementoosseous dysplasia on the basis of clinical & radiological features but was diagnosed as ossifying fibroma on the basis of histopathological feature. The histopathologic features of the multiple cementoosseous dysplasia and cementoossifying fibroma have common features of cementum, fibrous network and bone. Multiple cementoosseous dysplasia is reactive lesion and shows restricted lesion size, occurred on anterior and posterior tooth of the mandible and needs no treatment except periodic follow up. But Cementoossifying fibroma is the true neoplasm and grows continuously and needs surgical removal. The final diagnosis of the multiple cementoosseous dysplasia requires good correlation of the clinical histopathological, and radiological features.

Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis and this is characterized by asymptomatic soft tissue swelling that affects the lateral aspects of the proximal interphalangeal (PIP) joints of the fingers. Although the etiology of PDD is unknown, the possibility of repetitive minor trauma by habitual or compulsive habits of interlacing the fingers or rubbing of the fingers has been suggested as a cause by several authors. We experienced a 14-year-old boy who was diagnosed as having PDD by the clinical manifestations and this was supported by a radiological study and the routine laboratory tests. He also had the habit of repetitively manipulating his hands when feeling emotional distress. PDD sometimes can be misdiagnosed as a rheumatic condition. Although an unusual disorder, PDD should be considered in the differential diagnosis of patients who present with digital bulbous swelling.

BACKGROUND: Juvenile ossifying fibroma (JOF) is defined as a variant of the ossifying fibroma, and the latter includes juvenile trabecular ossifying fibroma (JTOF) and juvenile psammomatoid ossifying fibroma (JPOF). JOF can be distinguished from other craniofacial fibroosseous lesions by its tendency to recur and its clinical mimicry of malignant bone tumors, but some clinical and histological features of JOF overlap with the other fibro-osseous lesions as well. We aimed to identify the clinicopathologic definition of JOF. METHODS: Forty-two cases of fibro-osseous lesions were reviewed and they were classified into JOF, fibrous dysplasia (FD) and ossifying fibroma (OF). RESULTS: JTOF had long, slender and anastomosing trabeculae of osteoid in a fibrocellular stroma, and JPOF had small ossicles resembling psammoma bodies with a thick collagenous rim in the fibrous stroma, which are features that differ from those of FD and OF. Radiologically, JOF and OF showed a well-defined lesion but FD exhibited an ill-defined lesion. Clinically, the average age of the JOF patients was the youngest, followed by OF and FD. For JOF, three cases had rapid growth and two others showed recurrences. JOF mainly occurred in the paranasal sinuses, OF in the mandible and FD in any craniofacial bone. CONCLUSION: We demonstrated the distinct characteristics of JOF and these features may be helpful for the diagnosis and management of this malady.

Renal medullary fibromas which are arisen from the interstitial cell of the renal medulla show small, multiple nodules on autopsy Findings over age 50, but they are very rare clinically. thus several cases have been reported until 1982. When the tumors are large. their clinical presentation is characterized by loin pain, hematuria and palpable mass. The preoperative diagnosis with radiologic studies is very difficult and the confirmative diagnosis was made with pathologic finding. Nephrectomy has been the most common useful treatment and local excision can be used. We report a case of renal medullary interstitial cell fibroma in a 17-year-old girl presented with a child-head sized palpable mass on the left upper quadrant.

We report a case of trichoblastic fibroma involving the scrotum in a 60-year-old man. Trichoblastic fibroma is very rare and benign trichogenic tumor that has both epithelial and mesenchymal components and histologically recount the embryologic development of the hair follicle. The diagnosis was confirmed by histopathologic examination.

Desmoplastic fibroma of bone is an extremely rare tumor that was first described by Jaffe in 1958. It histologically resembles the desmoid tumor of soft tissue. It is known as locally aggressive tumor but we experienced definitely benign and resembling simple bone cyst radiographically. We report a case of desmoplastic fibroma of bone and it should be included in the differential diagnosis list of any lytic bone lesion. The radiograph, MR imaging features, radiological and pathological differential diagnosis of the case are described, and literatures are reviewed.
