Juvenile Psammomatoid Ossifying Fibroma of Fronto-Ethmoid Complex Mimicking Fibrous Dysplasia: Case Report

Juvenile Psammomatoid Ossifying Fibromais a rare fibro-osseous tumor seen in children and adolescentand mostly arising from the cranio-facial bone.We report a case of 18-year-old boy who presented with diplopiaand progressive right fronto-orbital swelling. On plain radiograph and CT, it was diagnosed as fibrous dysplasiaand mucocele as differential diagnosis. The tumor was resected and histopathological examination showed psammomatoid features. Therefore, the diagnosis of Juvenile Psammomatoid Ossifying Fibroma must be based on both radiological and histopathological findings.

Psammomatoid Ossifying Fibroma

Juvenile psammomatoid ossifying fibroma (JPOF) is a fibroosseous tumor that arises in the craniofacial bones in young people. This lesion usually originates in the jaw, orbit, and ethmoid complex but can also be associated with the skull base and calvaria. Diagnosis must be made based on observing typical radiological and histopathological features. Although JPOF is a rare pathological entity, neurosurgeons must consider this odontogenic lesion in the differential diagnosis of skull masses given the lesion’s aggressive behavior and locally invasive growth. Treatment must be gross-total resection. In the following article, the authors present a case of cranial JPOF and discuss various aspects of this entity.

Introduction: Intraosseous lipoma is a very rare neoplasm accounting for < 0.1 % of primary bone tumors. Pain is the leading symptom in majority of the reported cases but it can be asymptomatic. There is slight male predominance in occurrence of this lesion. The plain radiological findings are not specific and requires differential diagnosis. The lesion is mostly diagnosed by histopathological examination. Case report: A 31-year-old male presented with localized pain around the medial aspect of right ankle joint for one week. Examination revealed mild tenderness over the distal part of the right tibia over the medial aspect. Plain radiograph of the right leg showed well-defined expansile osteolytic lesion with sclerotic rim and calcified matrix at metaphysis of distal tibia. MRI showed enhancing T1-weighted hypo intense and T2-weighted hyperintense lesion. For this case, radiological impression was giant cell tumor with differential diagnosis of aneurysmal bone cyst and fibrous dysplasia. However, the histopathological examination showed intraosseous lipoma, consistent with stage II of Milgram’s classification. Conclusions: Although the diagnosis of intraosseous lipoma can be very challenging due to its rarity and indistinct plain radiograph findings, combination of computed tomography or magnetic resonance imaging may be useful by being able to show the presence of fat within the lesion. However, the clinicians, surgeons and radiologist should be familiar and be aware of these findings to be able to come to a correct diagnosis since not all cases need surgery and can be managed conservatively.

AbstractFibrosarcomas are malignant tumors of the connective tissue, which are characterized by proliferation of fibroblasts. Most of these tumors are localized subcutaneously and cause different symptoms depending on their location. The case report describes a dermal tumor on the outside of the pinna in a 7-year-old female Cashmere goat. The tumor was surgically removed and histopathological examination revealed a low grade fibrosarcoma. Although tumors are rare in ruminants because of the animals’ short lifespan (age of slaughtering in most cases < 24 months) in modern production processes, they should be considered as a differential diagnosis.

Clinical Differential Diagnosis

Tuberculosis of the oral cavity which is an uncommon occurrence can be primary or secondary. In the absence of active pulmonary tuberculosis, isolated tonsillar tuberculosis is rare. Herein, we report two cases of bilateral tonsillar tuberculosis who presented as recurrent sore throat for which tonsillectomy was done. No active primary pulmonary lesion was found in these cases. Histopathological examination revealed caseating epithelioid granulomas with Langhans giant cells. Ziehl Neelson stain for acid fast bacilli was positive in one case. Tonsillar tuberculosis, though a rare entity, should be considered in the clinical differential diagnosis of tonsillar lesions. Histopathological examination with Ziehl Neelson stain should be performed for definite diagnosis.

Skin Mucosa

Seborrheic keratosis is a benign tumour of skin, a common hyperkeratotic lesion of the epidermis,that usually occurs in the trunk and less frequently in the extremities, face and the scalp. A 65-year old farmer presented with a long standing, slowly growing, firm, redbrown, polypoidal mass about 2×2.5 cm in size, located at the skin mucosa interfare of the tip of nose. The lesion was excised under general anesthesia and histopathologic examination showed seborrheic keratosis. Diagnosis is made on the basis of clinical & histopathological examination. Here, we discuss the clinical presentation, differential diagnosis, pathological diagnosis and management of such a case. There was no recurrence during a year follow-up.Bangladesh J Otorhinolaryngol; October 2015; 21(2): 119-121

AbstractPeripheral odontogenic fIbroma (POF) is a rare odontogenic tumor. It resembles clinically with other peripheral exophytic lesions like pyogenic granuloma, peripheral ossifying fibroma, and peripheral giant cell granuloma. Hence, needs to be differentiated from such other lesions. Histopathological examination being the only diagnostic approach for peripheral odontogenic fibroma, which can provide a basis for treatment and prognosis evaluation. This case report presents a rare clinical case of a 14-year-old female patient with a palatal overgrowth along the maxillary incisors, which was diagnosed as peripheral odontogenic fibroma.
