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.

Psammomatoid Ossifying Fibroma

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.

Background Hyalinizing clear cell carcinomas (HCCCs) are rare, low-grade, malignant tumors which most often arise from the minor salivary glands primarily in palate and tongue but can arise in any location with minor salivary glands including the nasopharynx. Methods A case report of primary nasopharyngeal HCCC is presented. Because of the rarity of this tumor and location, a literature search was conducted to determine the most common presenting symptoms, treatment strategies, and outcomes. Results A 48-year-old man underwent biopsy of a 4.5 cm mass of the right nasopharynx with pathology suggesting an intermediate grade mucoepidermoid carcinoma. After discussing management with the patient, an endoscopic resection was performed. Final pathology revealed an HCCC which was confirmed after negative Mastermind-like 2 (MAML2) and positive Ewing sarcoma breakpoint region 1 (ESWR1) gene rearrangements on fluorescence in situ hybridization (FISH) studies. Literature review of other nasopharyngeal HCCC cases shows diverse presentation and overall excellent prognosis through surgical and radiation therapy. Conclusion HCCCs are rare, low-grade malignant tumors of the minor salivary glands and can present as a nasopharyngeal mass. Presenting symptoms are diverse but frequently involve otologic and sinonasal disturbances. HCCC is an indolent tumor with an excellent prognostic outcome when treated appropriately with surgical resection and adjuvant radiotherapy.

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

Lipomatous Tumors

Introduction. Chondrolipomas and osteolipomas are uncommon variants of lipomatous tumors. Case report. We presented a 60-year-old woman with ossifying chondrolipoma of the tongue. Clinical examination revealed a firm nodular mass, located in the midline of the posterior region on the dorsal surface of the tongue. Histologically, the lesion was well-delimited showing areas of mature adipocytes arranged in lobules and separated by fibrous connective tissue septa, islands of mature cartilaginous tissue and osseous metaplasia. Trabeculae of lamellar bone within a fibro-fatty background were visible throughout the tumor. The cartilaginous areas merging centrally with bone formation and fatty marrow tissue were present, as well as the hematopoietic elements in the fatty marrow. The bone forming was found to be through both membranous and enchondral mechanisms. Conclusion. Ossifying chrondrolipoma with hematopoietic elements is extremely unusual lesion. This interesting entity should be kept in mind in the differential diagnosis of lingual lesions.

Introduction. Cystadenofibromas are tumors of the ovary which originate from the surface coelomic epithelium. Benign mucinous cystadenofibroma is a very rare form of these tumors, which consists of dominant stromal component of the connective tissue and one or more cysts. Case report. The case of a 62-year-old female with tumor of right ovary is reported in this paper. Histologically, tumor of the ovary had multilocular cystic formation, lined by a single-layer of mucoproductive cylindrical epithelium - endocervical type. In one area of tumor, the stromal component was abundant and made from partially hyalinised dense connective tissue. Mucinous cystadenofibroma was diagnosed on the basis of histological examination. Since the mucinous type of cystadenofibroma or adenofibroma is rare, this case has been chosen to be presented. Conclusion. Mucinous cystadenofibromas are differentially- diagnostically very similar to different malignant tumors and it is extremely important to make correct diagnosis of these neoplasms.

Chondrosarcoma is a rare variant of bladder tumor and one of the rare types of soft tissue sarcoma. This case happened on a 36-year-old male who complained of lumps in his lower abdomen, accompanied by difficulties in passing urine and painful urination, without hematuria. We performed TURBT and histopathological examination showed low-grade chondrosarcoma. The patient was diagnosed with low-grade bladder chondrosarcoma. The patient was treated for chemotherapy and radiotherapy. However, after undergoing one cycle of chemotherapy, the patient refused to continue the therapy.

Abstract Chordomas are low-grade malignant tumors of bone that occur almost exclusively in the axial skeleton. Other neoplasms with a similar histologic picture but an extra-axial location have been described, including parachordoma, myxoid chondrosarcoma, and extra-axial chordoma. We herein present another case of the rare extra-axial chordoma. A 41-year-old woman developed an 8.3 cm mass in the pubic bone. The gross, microscopic, and immunohistochemical findings were identical to those of a classic chordoma. Parachordoma and myxoid chondrosarcoma were excluded from the differential diagnosis. Five previously reported cases of extra-axial chordoma were reviewed and found also to demonstrate clinical and pathologic features specific to chordoma, despite arising in an extra-axial location. Although rare, extra-axial chordoma does exist and should be recognized and managed in a similar fashion to its well-described counterpart. It must be differentiated from other histologic mimics, because the treatment and prognosis can differ significantly.

Upper Gastrointestinal

Prostate cancer commonly metastasizes bones and lymph nodes, but it very rarely spreads to the gastrointestinal tract. However, only five cases of prostate cancer metastatic to the stomach have been previously reported in the literature. We report a case of a 69-year-old man with metastatic prostate cancer who presented with upper gastrointestinal bleeding (UGB) 4 years after the diagnosis. Esophagogastroscopy revealed multiple ulcerations in the gastric body and histopathological examination confirmed gastric metastasis that originated from prostate cancer. Chemotherapy could not be given because of patient's refusal. He was treated with LHRH agonist. We suggest that for a man with prostate cancer diagnosed with UGB, stomach metastasis should be considered in the differential diagnosis of UGB.
