A 9-year-old castrated male pitbull dog was presented for evaluation of a subconjunctival swelling of 10 days duration. On ophthalmic examination, a subcutaneous mass was identified at the right lateral canthus. An excisional biopsy was performed, and histopathological analysis confirmed a diagnosis of a subcutaneous fibroma. Eleven months after surgical excision, the dog had no evidence of recurrence. Fibroma should be included in the differential diagnosis of rapidly enlarging eyelid masses.

Solitary fibrous tumors of the pleura are uncommon mesenchymal tumors that have been reported in adults. There are very few cases in children. These tumors are considered benign but their behavior is often unpredictable because they can invade nearby structures and transform into malignant variants after several years. Their clinical presentation is diverse but generally asymptomatic and they are detected incidentally in routine radiologic studies. Prognosis depends firstly on resectability of the tumour and secondly on its size, mitotic count, polymorphism, and necrosis within the tumour. Surgical resection is usually curative. Long-term follow-up is recommended because local recurrences can occur after surgery. We report the case of an asymptomatic 15-year-old girl with a giant thoracic mass revealed incidentally on a chest radiograph. Physical examination revealed thoracic asymmetry and no sounds of breathing were found in the right lung. Computerized tomography and magnetic resonance images showed the giant size of the mass. Preoperative fine needle biopsy was performed. Intraoperative biopsy confirmed the diagnosis. Although histologically benign, the tumors may enlarge rapidly. In the present case, because of the localization and size of the tumor, the patient was at increased risk. The tumour was resected and the postoperative course was uneventful. At present our patient remains under long term annual follow-up.

BACKGROUND/AIM
Endosialin is present in human fibrosarcoma neoplastic cells. This study aimed to analyse the expression of selected cellular proteins found in fibrosarcomas and soft-tissue fibroids in dogs.
MATERIALS AND METHODS
A total of 71 skin tumours obtained from dogs were used. The samples included 31 fibromas and 40 fibrosarcomas. Histopathological evaluation was performed according to World Health Organization guidelines. Immunohistochemistry was performed with anti-endosialin, Ki-67, cyclo-oxygenase 2 and vimentin antibodies and assessed using the semi-quantitative scale.
RESULTS
Endosialin expression was observed in 82.5% of fibrosarcomas and in 35% of fibromas. A significant positive correlation was found between the expression of endosialin in fibrosarcoma neoplastic cells and the degree of histological malignancy and the expression of the Ki-67 and cyclo-oxygenase 2 antigen. Expression of vimentin confirmed mesenchymal origin of this tumours.
CONCLUSION
The results of our research suggest that endosialin is involved in the carcinogenesis of fibrosarcoma in dogs.

BACKGROUND
The aim of the present study was to evaluate the prevalence of non-ossifying fibroma (NOF) and fibrous cortical defect (FCD) in a Japanese pediatric population and the association between the lesion size and pain.
METHODS
This retrospective study, conducted across 10 Japanese institutions, included patients aged 5-15 years who had undergone standard antero-posterior and lateral view radiography of the knee. Using these radiographs, we diagnosed the lesion as a NOF or FCD. Patient demographics, including age, sex, the size and location of the NOF, and chief complaint were recorded. The lesion size was determined using radiographs. Student's t-test was used to compare the associations between the lesion size and spontaneous pain.
RESULTS
A total of 6222 subjects (3567 boys and 2455 girls) were included in this study. The number of NOF and FCD cases was 143 and 437, respectively, and the prevalence of NOF and FCD was 2.3% and 7.0%, respectively. The average size of NOF and FCD was 22.1 mm (range: 4-102 mm) and 13.2 mm (range: 5-21 mm), respectively. Three patients (2.1%) had pathological fractures due to NOF. Of the 140 NOFs and 437 FCDs, we obtained complaints from the medical records of 126 and 393 patients, respectively. The number of patients with spontaneous pain or other problems with NOF was 68 (54%) and 58 (46%), respectively, that of patients with FCD was 195 (50%) and 198 (50%) patients, respectively. The lesion size was not associated with spontaneous pain in either lesion (p = 0.67 and p = 0.27, respectively).
CONCLUSION
The prevalence of NOF and FCD around the knee was lower than that reported in previous studies. The prevalence of NOF increased and that of FCD decreased with advancing age. In both lesions, the lesion size may not be associated with pain.

Pachydermodactyly is a rare form of digital fibromatosis. There are only 15 cases reported in the literature, all with a negative family history. Only one of the previously reported cases was a woman. We now report 2 female cases, mother and daughter, who, to the best of our knowledge, are the first patients with familial pachydermodactyly. The histological evolution of this disease over the years had not been previously reported.
